Test Description
HSV Type 1 & 2 Quant PCR, Blood/Eye Fluid

Herpes Simplex Virus by PCR, PCR for Herpes Simplex, UOW3537

Test ID
General Information

The detection and quantitation of Herpes Simplex virus (HSV) by real-time PCR amplification. PCR detects amplicons of the gB gene for both HSV-1 and HSV-2. The two probes used in the reaction, specific either to HSV-1 or HSV-2 are labeled with different reporter dyes. Quantitation of HSV DNA (copies/mL) is achieved by amplifying a standard curve consisting of serial dilutions of a known amount of DNA containing the HSV-1 and HSV-2 amplicons. Results are reported in copies per milliliter (copies/mL). The minimum virus level that gives a positive result in 95% of replicates is 250 copies/mL (2.40 log copies/mL).

This test was developed and its performance characteristics determined by the University of Washington Department of Laboratory Medicine and Pathology. It has not been cleared or approved by the US Food and Drug Administration

Container Type

Blood or Clear non-cellular fluid (e.g. BAL, Washing).

Specimen Requirements

Blood: 3 mL blood in EDTA (LAVENDER TOP) tube.

Eye Fluid: 50 microliters in sterile container.

NOTE: Do not send syringe with needle. Only send syringe or transfer fluid to sterile container.
