What is the Zika Virus Test?

The Zika Virus Test uses clinical microbiology methods to look for evidence of infection or immunity.

Background: Zika is a virus that is spread mostly by mosquitoes. A pregnant mother can pass it to her baby during pregnancy or around the time of birth. It can spread through sexual contact. There have also been reports that the virus has spread through blood transfusions. There have been outbreaks of Zika virus in the United States, Africa, Southeast Asia, the Pacific Islands, parts of the Caribbean, and Central and South America. Most people who get the virus do not get sick. One in five people do get symptoms, which can include a fever, rash, joint pain, and conjunctivitis ( pink eye ). Symptoms are usually mild, and start 2 to 7 days after being bitten by an infected mosquito. A blood test can tell …

How the Zika Virus Test works

Methods vary by pathogen: antibody serology detects your immune response (IgG/IgM), antigen tests find pathogen proteins, NAAT amplifies pathogen genetic material, cultures grow the organism, and microscopy inspects specimens directly.

Medical Tests may earn a commission when you order through partner links. Ordering direct-to-consumer tests does not replace care from a qualified healthcare provider.

Why healthcare providers order it

Ordered when exposure history, symptoms, travel, or screening protocols raise the question of a specific infection — and for immunity checks (titers) before school, work, pregnancy, or after vaccination.

Interpreting your results

Understanding infectious-disease results

IgG positive: past infection or vaccination — usually immunity.
IgM positive: suggests recent/active infection, though IgM can persist and false positives occur; confirmatory testing is standard.
Antigen/NAAT positive: direct detection of the pathogen — active infection.
Culture positive: organism grown and identified; sensitivity testing guides antibiotic choice.
Negative: no detection, subject to window periods and specimen quality.

Reference intervals vary by laboratory, instrument, age, sex, and — for hormones — collection time. Always compare your value against the range printed on your own report, and review results with a qualified healthcare professional who knows your history. This guide is educational and does not diagnose.

Understanding your lab report

Find the reference interval printed beside your value on the report — that pairing defines 'normal' for this lab run.
Note the units. mmol/L vs mg/dL, ng/mL vs µg/L — numbers mean nothing across unit systems.
Look at flags (H/L) but read the degree: barely-outside values behave differently than multiples of the limit.
Trends outrank snapshots. A series of results tells your provider far more than any single draw.

Frequently asked questions

What does the Zika Virus Test measure?

It quantifies a specific biomarker or characteristic of the submitted sample, compared against a laboratory-defined reference interval.

Do I need to fast before the Zika Virus Test?

Fasting is not routinely required for this test; follow any instructions from your provider or laboratory.

How soon do Zika Virus Test results come back?

Most routine assays return within 1–3 business days; specialty methods can extend that to a week or more.

Can an abnormal Zika Virus Test result mean something serious?

Many of these infections are treatable; a positive result is interpreted with your symptoms, exposure history, and confirmatory testing.
