Ordering Recommendation
Not recommended for herpes simplex virus (HSV) testing; IgM lacks adequate predictive value for acute infection. If pursuing antibody testing, refer to Herpes Simplex Type 1 and Type 2 Glycoprotein G-Specific Antibodies, IgG by CIA (0051152). If acute HSV infection is suspected, molecular testing is preferred; refer to Herpes Simplex Virus (HSV-1/HSV-2) Subtype by PCR (2010095).
