A Zika virus test checks for evidence of infection with the Zika virus, which is mainly spread by certain mosquitoes. It is ordered when a person has symptoms and recent exposure, or when screening is needed during pregnancy.

What it measures

  • Zika virus RNA (PCR) — Detects genetic material from the virus, usually in blood or urine during early infection.
  • Zika virus IgM antibodies — Shows the body's early immune response to a recent or current infection.
  • Zika virus neutralizing antibodies — A confirmatory test that helps distinguish Zika from similar viruses like dengue.
  • Plaque reduction neutralization test (PRNT) — A specialized test to confirm which flavivirus is present when initial results are unclear.

Who it is for

A clinician may order this test for anyone with symptoms and a history of travel to an area with Zika, or for pregnant people with possible exposure. It is not a routine screening test for most adults.

Preparation

No fasting or special preparation is needed. Tell your clinician about any recent travel and the date your symptoms began, as timing affects which test is used.

Results and what they mean

Results are reported as positive, negative, or inconclusive, sometimes with a note about which test was used. A positive result does not always mean active infection, and a negative result may not rule it out if testing is done too late. Only a clinician can interpret these results in context. This is general information, not medical advice.

Requesting the Zika Virus Test in California

Order online, choose a certified collection site in California, and review results through a secure portal. No referral is required, and orders are processed confidentially. Access across Pacific is uneven, so confirming a site ahead of time is worthwhile.

Frequently asked questions

How long does it take to get results?

Most results are available within 1 to 3 business days, though confirmatory testing may take longer.

Can I get Zika from a blood test?

No. The test uses a small blood sample, and you cannot catch Zika from the test itself.

Do I need this test if I feel fine?

Usually not. Testing is mainly for people with symptoms or specific risk factors, such as pregnancy with possible exposure.

What should I do if my result is positive?

Talk with your clinician. They can explain what the result means for you and discuss next steps.
