Specimen Collection Criteria

Collect: One of the following specimen types:

  • Blood: One Lavender-top EDTA tube or Gold-top SST tube
  • Cerebrospinal Fluid: 1 mL CSF in a sterile collection container. (Minimum: 0.5 mL)
  • Urine: 1 mL urine in a sterile collection container. (Minimum: 0.5 mL)

Physician Office/Draw Specimen Preparation

Centrifuge blood specimens to separate serum or plasma from cells within two hours of collection. Transfer serum or plasma to a plastic transport tube and freeze (-20°C/-4°F or below) immediately. Maintain CSF and urine specimens frozen (-20°C/-4°F or below) prior to transport.

Preparation for Courier Transport

Transport: 1 mL serum, plasma, CSF, or urine, frozen (-20°C/-4°F or below). (Minimum: 0.5 mL)

Rejection Criteria

Specimens not collected or processed as indicated.

In-Lab Processing

Clinical Utility

The detection of JCV can aid in the diagnosis of progressive multifocal leukoencephalopathy (PML), a viral infection that infects the human central nervous system. JCV is usually associated with immunosuppression of the cell-mediated immune system in patients with lymphoreticular malignant disease, organ transplantation, and acquired immunodeficiency syndrome.
