Limitations of Zika Testing No test is 100% accurate. A test result can sometimes be negative in the setting of true infection, and the results could be falsely reassuring.

While the Zika virus remains in the blood of an infected person for a few days to a week, according to the CDC, there's no current evidence to suggest that it poses a risk of birth defects in future pregnancies. And Zika won't cause infections in a baby that's conceived after the virus has left the bloodstream.

When used correctly, home pregnancy tests are 97–99 percent accurate. A pregnancy blood test is done in a health care provider's office. It can find smaller amounts of HCG, and can confirm or rule out a pregnancy earlier than a urine test.

Pregnancy after Infection has Cleared There is no evidence that a fetus conceived after the virus has cleared the woman's body would be at risk for fetal Zika infection. Current evidence suggests that Zika virus infection prior to pregnancy would not pose a risk of birth defects to a future pregnancy.

“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.

Accuracy. As with urine/home pregnancy tests, it is possible to end up with false results (both negative and positive) from a blood pregnancy test.

The HIV RNA test is actually more accurate than other types of HIV test even though it is done far earlier than other types of tests. Thanks to the polymerase chain reaction process used during testing, even damaged fragments of HIV RNA are not missed. When performed correctly, HIV RNA test is over 99.9% accurate.

If signs of infection are found, the result is "positive". The blood test is the most accurate test and can normally give reliable results from 1 month after infection. The other tests tend to be less accurate and may not give a reliable result for a longer period after exposure to the infection.

Diagnosis. Infection with Zika virus may be suspected based on symptoms of persons living in or visiting areas with Zika virus transmission and/or Aedes mosquito vectors. A diagnosis of Zika virus infection can only be confirmed by laboratory tests of blood or other body fluids, such as urine or semen.

If you get infected with Zika during pregnancy, you can pass it to your baby. It causes a birth defect called microcephaly and other brain problems. Zika virus also spreads through mosquito bites and through body fluids, like blood and semen.

FIRST RESPONSE™ is >99% accurate from the day of the expected period in laboratory studies. However, some pregnant women may not have detectable amounts of pregnancy hormone in their urine on the day of the test or may have miscalculated the first day of their period.
