Zika Virus Test Test
A Zika virus test checks for signs of Zika infection in your blood or urine. It is mainly used for pregnant women who have traveled to areas with Zika risk, because the infection can cause serious birth defects.
What this test measures
A Zika virus test looks for signs of the Zika infection in your blood or urine. There are two types: molecular tests (like PCR) that find genetic material from the virus, and antibody tests that find antibodies your immune system makes to fight Zika.
What your results mean
Reference ranges vary by laboratory and by your age and sex. MedlinePlus does not publish a single normal range for this test — always read your result against the range printed on your own lab report and discuss it with your provider.
Higher-than-normal results
A positive Zika test result means you probably have a Zika infection.
Lower-than-normal results
A negative result can mean that you aren't infected or that you were tested too soon for the virus to show up in testing.
