What is this test?

The Eastern equine encephalitis virus nucleic acid amplification test, or EEEV NAAT, looks for genetic material from EEEV in a respiratory specimen. It is a laboratory test performed on a sample collected by a healthcare professional.

Why might I need this test?

This test may be ordered when someone has fever, headache, confusion, seizures, or other symptoms of a neurologic infection and has been exposed to an area where EEEV is found. EEEV is a mosquito-borne virus that can cause serious illness.

How is the test performed?

A respiratory specimen is collected and tested in the laboratory using a nucleic acid amplification method, which can detect even small amounts of viral genetic material. The laboratory reports whether EEEV genetic material was detected.

How do I prepare for the test?

Preparation depends on the type of respiratory sample being collected. Follow your healthcare professional's collection instructions carefully, and tell the laboratory if you recently had a respiratory illness or received antiviral treatment.

Frequently asked questions

Does a positive EEEV NAAT mean I have encephalitis?
It means EEEV genetic material was detected and supports an active infection, but your symptoms, other laboratory findings, and imaging are also used to determine the diagnosis and severity.
Can this test detect a past EEEV infection?
No. This NAAT detects viral genetic material and is mainly useful during active infection; it is not a test for previous exposure or immunity.
What should I do if I have symptoms of EEEV?
Seek urgent medical care, especially if you have a severe headache, stiff neck, confusion, seizures, or weakness. Tell the clinician about any travel or outdoor exposure in areas where EEEV has been detected.
