Test Details
Methodology
Chemiluminescent immunoassay (CLIA)
Result 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.
Use
This test is used to detect TORCH antibodies and aid in the diagnosis of congenital infection.
Limitations
Serum samples collected too early in the course of infection may not have detectable levels of HSV IgG. In cases of suspected early disease, a repeat serum specimen should be collected 14-21 days later and submitted for testing.
The predictive value of positive or negative results depends on the prevalence of disease and the pretest likelihood of HSV-1 and HSV-2.
False-positive results may occur. Repeat testing, or testing by a different method, may be indicated in some settings (e.g., patients with low likelihood of HSV infection).
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.
