X or Y
A naturally important question to ask is “Is the DNA based, X or Y Early Gender Test right for me?” There are several factors that will help determine whether X or Y Early Gender Test is right for you. In order to provide you with the most accurate results review the following criteria:
Are you at least nine (9) weeks pregnant?
Recent discoveries in science has proven that there is fetal DNA in a mother’s blood as soon as five weeks into her pregnancy. HOWEVER, the X or Y Early Gender Test requires that you take this test nine (9) weeks after the first day of your last menstrual period to be eligible for our money back guarantee. Optionally you can select the X or Y test at eight (8) weeks, but we require a waiver to be signed. Click Here to calculate your X or Y Eligibility Date.
If we have determined you are not 9 weeks from the first day of your last menstrual period, we cannot run your test (unless a waiver is signed). It is imperative that you take our test at the eligible time. Please see our Refund Policy for more information.
Have you had a recent blood transfusion?
Blood that did not originate from the mother or her fetus can affect the results of the X or Y Early Gender Test. If a woman recently had a blood transfusion, we do not recommend taking the X or Y Early Gender Test.
Did you recently have an abortion or a miscarriage?
If you recently had a miscarriage or had to terminate your previous pregnancy, we recommend that you wait THREE (3) months post Dilation and Cutterage (D&C). There still may be residual fetal DNA from your previous pregnancy that may affect your test results.
Have you ever in your life had a bone marrow transplant from a male?
If you have had bone marrow transplant from a male donor, your marrow will have been replaced by male marrow cells. You are not eligible to take the X or Y Early Gender Test.

Yes, in fact, we encourage it! You can order the kit at any time, but you must wait until your eligible testing date to use it. The laboratory will not process samples collected before 9 weeks pregnancy (unless a waiver is signed to authorize the ultra sensitive X or Y test). This is the same as 9 weeks after your last menstrual period.
If you are 9 weeks from the first day of you last menstrual period (7 weeks post-conception) you are eligible to use the X or Y Early Gender Test. You may also opt to take the test early by signing a waiver. The X or Y Eligibility Calculator can be used with either the date of your last menstrual period (LMP), or the Projected Due Date, as determined by a medical professional. Your eligibility is strictly based on this calculation. Thus, it is extremely important that you provide us with the most accurate LMP date or Due Date. Intentional miss-reporting of these dates voids our warranty.
We recommend ordering ahead of time so you can be ready to use as soon as eligible. Order here.
Kits have a “shelf life” of approximately 2 years. If you purchase your kit and choose to wait to complete the test, simply keep the kit in a clean, dry, cool environment to prevent contamination until you are ready to use it.
If you haven’t yet ordered, you can order here.
Please refer to our refund policy page.
Do NOT take the X or Y Early Gender Test if any of the following conditions are true:
• You had a miscarriage or termination within three months of your current pregnancy
• You have had a bone marrow transplant from a male in your lifetime
• You have had a blood transfusion within the last 18 months
• You are taking medication to treat blood-related conditions and/or undergoing anti-coagulant therapy.
• You are less than 9 weeks from the first day of your last menstrual period (unless you sign a waiver authorizing the X or Y test earlier than 9 weeks pregnancy). Please use the X or Y Early Gender Test eligibility calculator to make a determination of the first date you are eligible to collect your sample. Unless your doctor has provided you with a specific conception date, it is company policy to go strictly with our calculator. Other ways of determining date of eligibility will not be accepted by X or Y Early Gender Test or covered under our Refund Guarantee. (Refund Policy)
X or Y Early Gender Test is not recommended for individuals that fall in any of the categories above. If you have any questions, please contact Customer Care.
If you do not fall in any of the categories above, you can order your kit here.
1. Order the X or Y Early Gender Test online
2. Receive your collection kit in the mail

Since the test only detects the presence of Y (male) Chromosomes, if you receive a “Girl” result, it means that both babies will be girls. If you receive a “Boy” result, it means that one or both babies are boys.
The X or Y Early Gender Test offers parents-to-be with an accurate, non-diagnostic gender determination at 9 weeks pregnancy (7 weeks post conception) through a DNA based, minimally invasive procedure that can be administered in the comfort and safety of your home, without any adverse risk to a mother-to-be or baby.
The X or Y Early Gender Test kit consists of alcohol swabs to clean the finger, lancets to prick the finger, and a FTA collection card for preservation of a few drops of blood. The completed kit is mailed to the X or Y laboratory for processing, then undergoes a very sensitive, quantitative PCR assay process targeting multi-copy Y-chromosome-specific loci (see research section for more detail).
What is the science that makes X or Y Early Gender Detection possible? The answer lies in DNA research, which has rapidly advanced our understanding of life. DNA science has demonstrated that there is fetal DNA in an expectant mother’s blood. In a natural process, fetal cells die and pass into the mother’s bloodstream. As these cells break down, their DNA is released into the mother’s own circulatory system. In other words, the cells decompose and free DNA is released into the mother’s bloodstream. And by using a small sample of the mother’s blood, we can determine, with ultra high accuracy, if there is Y-specific chromosomal DNA. If we detect Y-specific chromosomal DNA, the fetus is male. If there is no Y-specific chromosomal DNA, then the fetus is a female. Remember, females have two X chromosomes, while males have one X and one Y chromosome.
In summary, fetal DNA in a mother’s blood makes this scientific process possible. Next, discover why it matters here.
X or Y Early Gender Test is +98% accurate based on controlled laboratory setting studies for ideal samples starting at 9 weeks pregnancy and older. The company has implemented a program that monitors our accuracy rate and service quality on an ongoing basis. You may be offered the opportunity to participate in our ongoing quality monitoring program during your ordering process or after your testing is completed.
There are several factors which may affect the accuracy of a X or Y result. Some of these factors can be controlled and minimized by the customer and/or laboratory while others are independent factors that cannot be influenced.
Factors which could affect the accuracy of X or Y and which can be minimized:
- Not following the directions carefully: improperly handling kit components, improperly washing hands, and not sanitizing the collection area
- Contaminating the sample: allowing males to handle kit contents or assisting with sample collection.
- Taking the test earlier than 7 weeks post-conception (if you wish to test earlier at 6 weeks post-conception, sign the authorization waiver for the ultra sensitive X or Y test)
- Having a recent transfusion, miscarriage or abortion
- Providing an insufficient blood sample
- Leaving the sample in a hot environment
Factors which could affect the accuracy of X or Y which cannot be controlled:
- Having a bone marrow transplant from a male donor, blood transfusions, miscarriages or abortions: our technology can detect DNA from previous male pregnancies or from male blood/marrow donors as contamination in most cases. However, there may be instances where the accuracy of our test is affected by any of these conditions.
- Miscarriage: Women who have recently experienced a miscarriage must wait at least 3 months before they can use X or Y. If it has been at least 3 months since the miscarriage, then you are eligible to order X or Y.
- Having naturally low levels of fetal DNA: studies have determined that up to 2.8% of women have naturally low levels of fetal DNA. While X or Y is much more sensitive than the methods used in those studies, there may still women whose levels of fetal DNA are too low even for our test to detect. This is a difficult statistic to measure but we anticipate it is less than 2%.
- Vanishing Twin: some pregnancies begin with two (or more) fetuses but very early in the pregnancy, one of the fetuses terminates. In many cases, this occurs without the woman’s knowledge. If the “vanishing twin” is male and the remaining fetus is female, the results of X or Y may be incorrect.
- Previously pregnant with a boy: in very rare cases (less than 1%), fetal cells may remain in the mother’s body several years after birth. Our technology can detect some of this DNA as a form of contamination, however, there may be cases where the accuracy of the test may be affected by this rare occurrence.

No, X or Y does not replace an Ultrasound. Ultrasounds are used for medical and/or health reasons and not just for checking the sex of the baby. Studies have shown that ultrasounds have an accuracy rate of less than 85% before 12 weeks and are greater than 98% accurate at 21 weeks post-conception. Because it can take from five to six months to tell the gender of your baby using the ultrasound, we offer you X or Y Early Gender Test.
If you are EXCITED to know the sex of your baby, X or Y Early Gender Test is for you! X or Y Early Gender Test is a unique DNA-based test that tells you whether you are having a boy or girl! (results starting at 9 weeks after the start of your last menstrual period, approximately 7 weeks post-conception)
X or Y Early Gender Test is a service providing information that has no impact on the health of the mother or the baby. X or Y Early Gender Test makes no medical diagnoses, recommendations, treatments, or medical or health claims.
Chorionic villi sampling (CVS) is a prenatal test that can detect genetic abnormalities such as Down’s syndrome. Unlike amniocentesis, CVS does not screen for neural tube defects. It is performed earlier than amniocentesis—between the 10th and 12th weeks of pregnancy. In CVS, a catheter or thin needle is inserted into the womb to extract some of the chorionic villi—cells from the tissue that will become the placenta. The chorionic villi contain the same chromosomes as the fetus.
Why would I take this test?
You may want to have the CVS test if there is an increased risk of chromosomal or genetic birth defects, and if you would like test results as early in pregnancy as possible. The test is not routinely offered to all pregnant women because the test carries a small risk of miscarriage, and possibly other complications. Also, CVS usually isn’t recommended if a woman has bleeding or spotting during the pregnancy.
CVS may be offered because of:
- Advanced maternal age. The risk of bearing a child with certain chromosomal birth defects increases as a woman ages. Prenatal testing is offered if a woman will be 35 or older at the time of delivery.
- A previous child or pregnancy with a birth defect. A woman may be offered CVS or amniocentesis during subsequent pregnancies if she already has had chromosomal abnormality or genetic birth defects diagnosed in a prior pregnancy or child.
- Family history that indicates the baby may be at increased risk of inheriting a genetic disorder. Prenatal diagnosis is possible for virtually all chromosomal disorders, but not all genetic ones.
How is CVS performed?
In a private exam room, your vagina and cervix are thoroughly cleansed with an antiseptic. Then, with an ultrasound as a guide, your doctor inserts a thin tube through your vagina and cervix (transcervical CVS) to the villi, and uses gentle suction to remove a small sample. No anesthetic is required.
The physician may choose an alternate method to reach the chorionic villi by inserting a needle through the abdominal wall (transabdominal CVS), also using ultrasound guidance. Both forms of CVS have found to be equally safe, although the transabdominal CVS is recommended for women with a tipped uterus because the risk of miscarriage is higher if done transcervically.
After the procedure, the fetal heartbeat is checked with ultrasound before you leave the examination room. You may experience lower abdominal cramping following CVS; or some bleeding or spotting, which ordinarily stops within a few days. If you have these symptoms, tell your doctor.
Studies suggest CVS may be slightly more likely to cause miscarriage than amniocentesis. For women with an anteverted uterus, there is no increased risk of miscarriage. Complication rates from CVS have been shown to be lower among physicians who perform this test more frequently. Before consenting to this test, check with your doctor and determine how often he/she has performed this test.
There has been some concern that the test itself may be associated with limb deformities. However, many geneticists believe that CVS performed between the 10th and 12th weeks of pregnancy does not increase that risk.
How accurate are the CVS results?
Test results have a greater than 99 percent accuracy rate in ruling out certain chromosomal birth defects and specific genetic problems. However, the test is slightly more likely than amniocentesis to give inconclusive results.
Does a negative CVS result mean a baby will be born healthy?
More than 95 percent of the high-risk women who have any prenatal diagnosis receive reassuring news that their unborn babies do not have a disorder for which they were tested. However, no prenatal test can guarantee a healthy baby, since only some birth defects can be ruled out before birth. Three to four of every 100 babies have a birth defect.
Can birth defects diagnosed with CVS be treated?
Advances in prenatal treatment make it possible to treat some birth defects before birth. However, physicians are able to diagnose more birth defects than they are able to treat prenatally. If a fetus has a condition for which prenatal treatment is not possible, prenatal diagnosis may help parents to decide whether to continue the pregnancy or prepare emotionally for the birth.
Amniocentesis is a prenatal test that allows you and your practitioner to gather information about your baby’s health and development from a sample of your amniotic fluid. This is the fluid that surrounds your baby in the uterus. The test is most commonly done when a woman is between 15 and 20 weeks pregnant to determine whether the baby has genetic or chromosomal abnormalities, such as Down syndrome. Not all women choose to have this test, in part because it carries a small risk of miscarriage.
Other reasons that you may need to have amniocentesis include:
- To check on the well-being of your baby if you have a blood sensitization, such as Rh sensitization. This is a complex condition that can occur if your blood is a different type than your baby’s.
- To determine whether your baby’s lungs are mature enough for an early delivery if you appear to be in premature labor or require an early delivery for any reason.
- To diagnose or rule out a uterine infection if your water has broken prematurely or your practitioner has any other reason for suspecting you have one.
Which birth defects can amniocentesis detect?
Amniocentesis can identify several hundred genetic disorders, including some of the most common:
- Nearly all chromosomal disorders, including Down syndrome and Edward’s syndrome. The test is more than 99 percent accurate in diagnosing these conditions. An ultrasound, a combined first-trimester screening, or a multiple marker test may indicate whether your baby is likely to have these problems, but only amniocentesis can tell you for sure.
- Other genetic disorders such as cystic fibrosis, sickle cell disease, Tay-Sachs disease, and Huntington’s disease. Neither the multiple marker test nor ultrasound will pick up these problems. Only amniocentesis can provide the information needed to diagnose them in the womb.
- Neural tube defects such as spina bifida* and anencephaly*.
More than 95 percent of the high-risk women who have amniocentesis receive good news from the results. Only about 5 percent will be found to have a baby with a problem. Amniocentesis doesn’t detect every birth defect, however. A cleft lip or palate, for example, won’t show up on the test.
Is amniocentesis appropriate for me?
Although most centers will do an amnio for any pregnant woman who wants one, the procedure isn’t offered routinely to all pregnant women because it carries a small risk of miscarriage. It’s usually only offered to those found to have a somewhat increased risk of having a baby with a chromosomal or genetic defect.
You may be in this category if:
- You’ll be 35 years old or older on your due date. The risk of having a child with a chromosomal defect rises as a woman ages. The chance that you’re carrying a baby with Down syndrome, for instance, is about one in 270 when you’re 35 years old – compared to 1 in 1,250 when you’re 25.
- You’ve had another test, such as a multiple marker screen, a nuchal fold scan, or a “combined screening,” that indicated your baby is at a higher risk for a problem. If this is the case, you may first have a detailed ultrasound scan to look for physical signs of Down syndrome and other defects. If the ultrasound shows that there’s still cause for concern, you may want to have an amniocentesis for a definitive diagnosis.
- You’ve previously been pregnant with a child with a birth defect.
- You or your partner has a chromosomal abnormality or genetic disorder or a family history that puts your child at increased risk for genetic problems. Or you and your spouse are both carriers of a recessive genetic disorder such as cystic fibrosis or sickle cell disease.
What are the risks of the amniocentesis procedure?
In deciding whether to have this test, you’ll need to weigh your desire to know about your baby’s condition against the slight risk that the test will lead to a miscarriage. You’ll definitely want to discuss your options with a genetic counselor so that you understand all the risks and benefits of your choices. For example, you may decide to have a combined first-trimester screening or a multiple marker test first to gain more information about your risk for certain problems.
There are many reasons to want to know about your child’s condition. Even if you would never terminate a pregnancy for any reason, knowing in advance that your baby will have special needs allows you to prepare for the challenges you might face. You might want to switch to a better-equipped hospital with specialists, for example. Knowing what’s going on with your baby allows your medical team to monitor your pregnancy as needed and to bring a neonatologist or pediatric surgeon on board to prepare to help your baby after delivery. And a few problems can even be treated in utero, such as biotin dependence and MMA (methylmalonic acidemia), both life-threatening, though extremely rare, body chemistry disorders.
That said, you’ll want to consider the small risk that the procedure may cause you to miscarry. According to the Centers for Disease Control and Prevention (CDC), the risk of miscarriage from amniocentesis is between one in 200 and one in 400, depending on the skill and experience of the doctor performing it. You’d also have a slight risk of uterine infection in the days following the procedure (less than one in 1,000), which can sometimes lead to miscarriage. These are all things you should discuss with your partner, your practitioner, and a genetic counselor.
Is there any way to reduce the risks associated with amniocentesis?
The more times the physician who does the amnio has performed the procedure, the lower your risk of complications. Ask your practitioner or genetic counselor to refer you to a physician with plenty of experience, preferably one who does at least 50 amnios a year.
You’ll also want to make sure that an experienced registered diagnostic medical sonographer provides continuous ultrasound guidance during the procedure. This greatly increases the chances that the physician will be able to obtain enough fluid on the first try and avoid having to repeat the procedure. And when continuous ultrasound guidance is used, injuries to the baby from the amnio needle are very rare.
