Herpes Simplex Virus (HSV) Types 1 and 2-Specific Antibodies, IgG With Reflex to Supplemental HSV-2 Testing
- Herpes 1 and 2; HSV Types 1- and 2- Specific Antibodies, IgG; HSV-1 and HSV-2; HSV
For 163034 HSV-2 IgG, Type Specific:If patient result falls between 0.91 (Equivocal) and 5.00 (Low Positive) Index Values, the specimen will reflex to 163006 HSV-6 Supplemental test per CDC guidelines.
If reflex test is performed, additional charges/CPT code(s) my apply.
Expected Turnaround Time
1 - 3 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
For more information, please view the literature below.
Red-top tube, gel-barrier tube, or serum transfer tube
Causes for Rejection
Hemolysis; lipemia; grossly icteric; visible particulate matter; gross bacterial contamination
Detect IgG antibodies specific to HSV types 1 and/or 2 infection; confirm or rule out possible infection with herpes simplex types 1 and/or 2 virus in prenatal patients in whom HSV 2 infection can cause serious prenatal disease. Per CDC guidelines, specimens with equivocal or low positive results for HSV-2 type specific IgG will reflex for supplemental testing by another assay.
In a patient with no history of lesion disease, a positive result for this test may be indicative that the primary infection was asymptomatic. Once infected by HSV, it is possible for a patient to shed virus without the development of lesions (asymptomatic shedding). This test does not indicate the site of HSV infection. The magnitude of the Index Value is not indicative of the amount of antibody present in the patient sample. There is a considerable homology between HSV-1 and HSV-2 antigens, so that antibodies formed against either virus are highly cross-reactive. These assays are based on purified recombinant glycoprotein G-1 (HSV-1) or G-2 (HSV-2) antigens.
HSV-2 IgG Type Specific
HSV-2 IgG Supplemental
Positive / Equivocal
Indicates the presence of detectable IgG antibodies to HSV-2.
Positive / Equivocal
Unable to confirm the presence of IgG antibodies to HSV-2. Recommend retesting in 2 to 4 weeks.
This test is intended for qualitative determination only. The magnitude of the Index Value is not indicative of the amount of antibody present in the patient sample.
Chemiluminescent immunoassay (CLIA). Reflex of specimens equivocal and low positive for HSV-2 type specific IgG to a membrane based immunoassay.
Set up Monday thru Friday.
