JC Virus DNA Quantitative

What is the JC Virus DNA Quantitative test?

This molecular test measures the amount of JC virus DNA present in blood or cerebrospinal fluid using quantitative PCR, aiding in the diagnosis of progressive multifocal leukoencephalopathy (PML).


Why is this test done?

It is primarily used in immunocompromised individuals, particularly those with HIV/AIDS or those receiving immunosuppressive therapy, to detect JC virus infection and monitor disease progression.


How is the test performed?

A blood or cerebrospinal fluid sample is collected and tested using real-time PCR techniques for accurate quantification of JC viral DNA.


What do the results mean?

High levels of JC virus DNA are suggestive of active infection and may indicate PML. Low or undetectable levels suggest absence or remission of the virus.


Are there any precautions or preparations required?

No special preparation is needed for this test.
