JC Virus DNA, PCR, Whole Blood
Also known as: John Cunningham Virus, Polyomavirus
Use
Aid in the diagnosis of infections caused by JC virus
Special Instructions
It is important to collect the specimen in a lavender-top (EDTA) tube to ensure the proper preservation of the sample. Specimens should be shipped promptly due to stability constraints, and testing schedules may vary depending on confirmatory or reflex test needs.
Limitations
The test has a stability of 7 days at room temperature and refrigerated, but is unstable when frozen. Therefore, frozen specimens should not be used as they may not yield reliable results. The test's sensitivity and specificity are determined by the laboratory and may vary depending on specimen integrity and handling.
