How early in pregnancy can a blood test detect gender?

But developments in noninvasive prenatal tests (NIPTs) mean you can be let in on this little secret with a simple blood test — even if gender determination isn’t their main purpose — as early as 10 weeks into your pregnancy.

How accurate is a gender blood test at 12 weeks?

“Sometimes there isn’t enough fetal genetic material in the mother’s bloodstream to get an accurate reading, which could happen when blood is drawn too early in the pregnancy,” he says. But when conducted at the right time, NIPT is very rarely wrong, at about 99 percent accurate.

Can Down syndrome test be wrong NIPT?

NIPT is quite accurate for Down syndrome (99%) and for trisomy 18 (97%). It is less accurate for trisomy 13 (87%). In all cases, the results should not be considered certain unless confirmed by diagnostic testing. Two diagnostic procedures can usually confirm or disprove the results of NIPT.

What happens if NIPT is positive?

If you have a positive NIPT result, your healthcare provider will likely order additional diagnostic tests. In some cases, these diagnostic tests reveal that the baby doesn’t have a chromosomal abnormality after all.

Is it worth getting NIPT test?

Why have an NIPT? The NIPT is highly sensitive and picks up more than 99% of cases of Down syndrome. But it is still a screening test rather than a diagnostic test. This means it can only tell you whether there is an increased risk of having a baby with an abnormality, rather than give you a definitive answer.
