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

General Information

Lab Name

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

Lab Code

HS12QN

Epic Name

HSV Type 1 & 2 Quantitative PCR, Blood

Description

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.

Ordering & Collection

Specimen Type

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

Collection

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.

Clear non-cellular fluid (e.g. BAL or Washing): 1 mL sterile container.

Also Acceptable: 3 mL blood in GOLD SST, RED, or PPT (PEARL TOP) tube.

Unacceptable samples: Plasma collected in sodium or lithium heparin.

Note: Separate specimens MUST be submitted when both Viral Culture/Serology and PCR testing are ordered.

Minimum sample requirement: 0.5 mL

Quantity

requested: 1.0 mL serum/plasma, 50 microliters eye fluid
minimum: 0.5 mL serum/plasma/non cellular fluid.

Processing

Blood: Separate plasma/serum from whole blood within 24 hours of collection. Freeze at -10°C or colder and ship on dry ice. If freezer and/or dry ice is not available, ship immediately at 2-8°C (ice pack). Sample may be stored at 2-8°C (ice pack) for up to 48 hours of collection. Samples stored at 2-8°C greater than 48 hours old may be rejected. Do not freeze/thaw.

Eye Fluid: Freeze at -10°C or colder and ship on dry ice. If freezer and/or dry ice is not available, ship immediately at 2-8°C (ice pack). Sample may be stored at 2-8°C (ice pack) for up to 48 hours of collection. Samples stored at 2-8°C greater than 48 hours old may be rejected. Do not freeze/thaw.

Clear non-cellular fluid: Freeze at -10°C or colder and ship on dry ice. If freezer and/or dry ice is not available, ship immediately at 2-8°C (ice pack). Sample may be stored at 2-8°C (ice pack) for up to 48 hours of collection. Samples stored at 2-8°C greater than 48 hours old may be rejected. Do not freeze/thaw.

Outside Laboratory: Ship samples on dry ice. If freezer and/or dry ice is not available, ship immediately at 2-8°C (ice pack). Shipment time must not exceed 48 hours from collection. Sample may be stored at 2-8°C (ice pack) for up to 48 hours of collection. Samples stored at 2-8°C greater than 48 hours old may be rejected. Do not freeze/thaw.
