Herpes Simplex Virus Type 1 Glycoprotein G-Specific Antibody, IgG by ELISA (HerpeSelect®) : 0050292

Mnemonic: HERP I

Methodology: Semi-Quantitative Enzyme-Linked Immunosorbent Assay
Performed: Sun-Sat
Reported: 1-2 days
Specimen Required: Collect: Serum separator tube.

Specimen Preparation: Separate serum from cells ASAP or within 2 hours of collection. Transfer 0.5 mL serum to an ARUP Standard Transport Tube. (Min: 0.1 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Mark specimens plainly as "acute" or "convalescent."

Storage/Transport Temperature: Refrigerated.

Unacceptable Conditions: Contaminated, heat-inactivated, hemolyzed, or severely lipemic specimens.

Stability (collection to initiation of testing): After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
Reference Interval:
0.89 IV or less: Negative - No significant level of detectable IgG antibody to HSV type 1 glycoprotein G.
0.90-1.10 IV: Equivocal - Questionable presence of IgG antibody to HSV type 1.  Repeat testing in 10-14 days may be helpful.
1.11 IV or greater: Positive - IgG antibody to HSV type 1 glycoprotein G detected, which may indicate a current or past HSV infection.
Interpretive Data: Individuals infected with HSV may not exhibit detectable IgG antibody to type-specific HSV antigens 1 and 2 in the early stages of infection. Detection of antibody presence in these cases may only be possible using a nontype-specific screening test.
