Test Details
Methodology
Immunofluorescence (IF)
Result Turnaround Time
1 - 6 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
The clinical utility of serological testing for HHV-6 is largely limited to diagnosing infection in immunocompromised individuals and for identifying past infection/exposure to roseola infantum. IgG seroconversion or detection of HHV-6 IgM antibody may indicate a recent primary infection, reactivation or reinfection. Please note that nucleic acid amplification (PCR) is the recommended testing method for diagnosis of active HHV-6 infection.
