What is the 10 week blood test for in pregnancy?
Noninvasive prenatal testing (NIPT).
This cell-free fetal DNA test can be done as early as after 10 weeks of pregnancy. The test uses a blood sample to measure the relative amount of free fetal DNA in a mother’s blood. It’s thought that the test can detect 99% of all Down syndrome pregnancies.
Can you find out the gender at 9 weeks with blood test?

Tests Done Early in Pregnancy Expand All
- complete blood count (CBC)
- blood type and Rh factor.
- urine culture.
Is 9 weeks too early for genetic testing?
New cell-free fetal DNA testing can be performed as early as 9 weeks of gestation and carries no risk of miscarriage, permits earlier detection, and generally provides earlier information about a fetus’ sex, according to a recent perspective published in The New England Journal of Medicine.
What tests are done before 10 weeks?
The combined screening test (10 to 14 weeks)
This is called a nuchal translucency measurement. This test needs to happen between 10 and 14 weeks because the nuchal translucency measurement will change after 14 weeks + 1 day. It is not always possible to get this measurement, depending on the baby’s position.

How accurate is the blood test for gender?
The review, which looked at 57 studies representing 6,541 pregnancies, found the blood tests gave a genuine result (sensitivity) 95% of the time and that this result was accurate or correct for gender (specificity) 98.6% of the time.
How early can blood test detect gender?

An early sex blood test is usually done at the beginning of week 10 of pregnancy. It may take about one week for the results to come back. Your doctor will recommend a diagnostic test such as chorionic villus sampling (CVS) or amniocentesis if your cell-free fetal DNA test comes back positive for a genetic abnormality.
What is more accurate a blood test for pregnancy or ultrasound?
Quantitative blood serum test: This test is also known as the beta hCG test, measuring the exact amount of hCG in your blood. Because this test can detect even trace amounts of hCG, it is highly accurate. Doctors use this test, along with ultrasound, to diagnose an early pregnancy loss. 3
