| Zika Virus Test : What is a Zika virus test? A Zika virus test looks for signs of the Zika infection in your blood or urine. Zika is a type of flavivirus, as is dengue fever and West Nile. Like those viral infections, Zika is usually spread by mosquitoes, especially in areas with tropical climates, such as parts of Central and South America, Africa, Mexico, and islands in the Caribbean and Pacific. Because Zika can enter bodily fluids such as blood, urine (pee), and semen, it can also spread through sex with an infected person or from a pregnant woman to her fetus. There are two types of tests used to check for Zika infections: - Molecular tests. These tests look for genetic material from the Zika virus. The tests are also called nucleic acid amplification tests (NAAT or NAT). A PCR test (polymerase chain reaction) is a common type of molecular test that checks for the Zika virus in a sample of your blood or urine. This test is recommended if you're pregnant. - Antibody tests. Antibodies are proteins that your immune system makes to fight viruses and other germs. A Zika antibody test checks a sample of your blood for the antibodies that fight Zika. Your body needs time to make antibodies. So, to be accurate, an antibody test can be done starting within a week after symptoms begin. Zika virus outbreaks tend to come and go. The recommendations for Zika testing are likely to change as outbreaks develop and disappear. Even without confirmed cases of Zika in the U.S., it is still possible to get the infection.
