Frequently Asked Questions
How long after infection will HerpeSelect detect IgG antibodies?
HerpeSelect can detect HSV IgG antibodies as quickly as 3 weeks after the onset of a patient's symptoms4. It is important to note that each individual may seroconvert at different rate leading to earlier or delayed detection. Some patients do not seroconvert for 6 months or longer.
Is there a need for HSV IgM testing?
The presence of IgM antibodies in herpes simplex virus (HSV) infections is difficult to interpret. The presence of IgM may indicate a true primary infection. However, the test has low sensitivity, high incidence of cross-reactivity and low negative predictive value (NPV). Additionally, the presence of IgM may be due to the reactivation of a latent HSV-1 or HSV-2 infection. For these reasons, IgM testing is not recommended, but may offer information about a particular patient’s antibody response.
What confirmatory testing is necessary for HerpeSelect type specific assays?
As with other serological tests, false results may occur. Repeat testing or testing with a different device may be indicated in some circumstances, for example, patients with a low likelihood of HSV infection. All results must be correlated with clinical history, epidemiological data, and other data available to the attending physician in evaluating the patient.
