A simple blood test can determine a baby’s gender as early as eight weeks of pregnancy. The blood sample is usually taken from the mother’s arm and is analyzed to determine if any fetal DNA is present. This is a non-invasive DNA test, which is 100% safe for both mother and unborn child.
What Are Blood Tests That A Doctor Can Do?
In the past, the standard of care for those at risk of having a baby with certain genetic conditions or other complications was one of two genetic screenings performed in the first trimester: chorionic villus sampling (CVS) or an amniocentesis.
These provide a pretty accurate picture of the baby’s genetic health, but they’re also invasive and carry a risk of miscarriage.
So, it is not ideal or worth the risk without other medical reasons, although they allow finding the baby’s sex before the 20-week ultrasound.
Now expectant parents have other options. In fact, 10 years ago, researchers developed a much less invasive test called cell-free DNA screening. Because the baby’s DNA shows up in the blood, it can be used to screen for things like:
- Down syndrome
- Edwards syndrome
- Patau syndrome
These are three of the most common genetic fetal conditions. For those with high-risk pregnancies, cell-free DNA screenings are recommended, which reveal the likelihood of the baby having one of these genetic conditions. Today, they’re being offered more widely.
What’s The Difference Between Baby Gender Test And Ultrasound?
Whether the child will be a girl or a boy is determined at conception, even before most women even know they are pregnant. In fact, sex chromosomes are both carried by the egg from the mother and the sperm from the father. That said, the egg always contributes an X chromosome, on the other hand, the sperm contribute either an X or a Y chromosome.
Moreover, the sex of the baby is thus determined by the sperm cell fertilizing the egg first. If the sperm carries an X chromosome, the baby will be a girl. If the sperm has a Y chromosome, it means a boy.
Although the gender of the baby is determined when the egg is first fertilized, pregnant women have to wait until their mid-pregnancy scan (at around 16 weeks) to determine the baby’s gender. Because of that, ultrasound shouldn’t be relied upon since statistics show that ultrasounds could be wrong up to 10% of the time.
Although it’s an essential tool for monitoring the progress of a pregnancy, ultrasounds were not designed for sex prediction. Preferably, it’s advised to wait until after 18 weeks of pregnancy to get a more reliable prediction of gender from an ultrasound scan.
What Is An Early Sex Blood Test?
Prenatal genetic tests may inform parents-to-be about the chances of their fetus having genetic abnormalities. Here are two main kinds of prenatal genetic testing:
- Screening
- Diagnostic
Additionally, prenatal screening testing may identify the likelihood of the baby having defects at birth (many of these are genetic abnormalities). These tests are:
- Blood tests
- Prenatal screening for cell-free DNA
- A specific type of ultrasound
Healthcare providers usually perform a prenatal screening test during the first or second trimester. Screening tests don’t definitively diagnose birth defects — if the test results indicate an increased risk of a genetic disorder, additional diagnostic tests may be needed to confirm a diagnosis.
What Are The Available Gender Blood Test?
Parents can conduct blood tests to determine their child’s gender. Most of them have minimal risks and can be undertaken at early pregnancy stages. These tests include:
Free Cell DNA Test
This test uses fragments of the fetus’ DNA to determine the health status and gender of the child and can be performed as early as week 7 of pregnancy. Fetal DNA testing is non-invasive and can be performed throughout pregnancy. It has no risks to pregnancy and is 95.4% accurate for boys and 98.6% for girls.
These DNA fragments swim through the placental wall into the mother’s bloodstream and are visible at 5 weeks. In addition to gender, this test can determine Duchenne muscular dystrophy, paternity, hemophilia, congenital adrenal hyperplasia, and Rh blood group type. Free cell DNA testing may diagnose other disorders, including cystic fibrosis, Down’s syndrome, and Beta-Thalassemia.
NIPT test; (stands for non-invasive prenatal testing)
It is a blood test to screen for Down syndrome and a few other chromosomal conditions. NIPT can be done at 10 weeks of pregnancy or later. Results are usually available in a week or two, sometimes a little sooner.
Most pregnant women find out their baby’s sex (if they choose to know) and expecting twins during their mid-pregnancy ultrasound, usually between 16 and 20 weeks. However, the technician may not be able to tell for sure if she can’t get a clear view of the baby’s genitals.
Sneak Peek Early Gender Test
SneakPeek® is a non-invasive prenatal testing (NIPT) method that utilizes the natural process of shared fetal DNA circulating inside the mother’s bloodstream. They can test for the presence of male DNA from the small sample of blood supplied via a finger stick.
Ramzi Test
The Basics of The Ramzi Theory. “Ramzi’s method using placenta/chorionic villi location as a marker for fetal gender detection at 6 weeks gestation was highly reliable. This method correctly predicts the fetus gender in 97.2% of males and 97.5% of females early in the first trimester.”
When To Have A Blood test To Find Out The Sex Of The Baby?
A blood test to determine the sex of a baby may help identify fetuses that are at an increased risk of developing severe genetic diseases (recessive disorders linked to the X chromosome) in pregnant people who have either delivered a baby with a recessive disorder linked to X chromosome or are carriers of these disorders.
The Bottom Line
Non-invasive prenatal screening tests analyze the blood of a pregnant person to determine the likelihood of certain genetic disorders in their fetus. Royalty Wellness Spa offers Sneak Peak Clinical Early Gender DBA Test, which is the only 99.9% accurate early gender DNA test as early as seven weeks of pregnancy. Ultimately, SneakPeek Clinical is the most accurate early gender test on the market.
