: What This Test Detects

: The test uses a molecular probe technique to identify varicella-zoster virus DNA. It is a qualitative test, meaning it reports whether viral DNA is detected rather than measuring an exact amount.

: Why It May Be Ordered

: Your healthcare provider may order this test when chickenpox or shingles is suspected but the diagnosis is uncertain, or when a person has an unusual rash or symptoms that could be caused by several different conditions.

: How the Sample Is Collected

: Depending on your symptoms, the sample may be fluid swabbed from a blister or rash, cerebrospinal fluid, or another body fluid. Your provider will explain how your particular sample will be collected.

: Understanding the Result

: A detected (positive) result means varicella-zoster virus DNA was found in the sample. A not-detected (negative) result means it was not found. Results are interpreted together with your symptoms and other findings, so discuss what your result means with your provider.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

: Does a positive result always mean I have chickenpox or shingles?
: A positive result shows the virus's DNA is present, but your provider will interpret it alongside your symptoms and history to determine what it means for you.
: Can this test tell how much virus is present?
: No. This is a qualitative test that reports whether viral DNA is detected, not the quantity.
: Is this test the same as an antibody test?
: No. This test looks for the virus's DNA directly, while antibody tests look for your immune system's response to the virus.
