Iw. Fong et al., DIAGNOSTIC-VALUE OF DETECTING JC VIRUS-DNA IN CEREBROSPINAL-FLUID OF PATIENTS WITH PROGRESSIVE MULTIFOCAL LEUKOENCEPHALOPATHY, Journal of clinical microbiology, 33(2), 1995, pp. 484-486
JC virus DNA was detected by PCR in the cerebrospinal fluid of 17 of 2
3 (73.9%) patients with confirmed cases of progressive multifocal leuk
oencephalopathy and 2 of 48 (4.2%) controls without progressive multif
ocal leukoencephalopathy. The sensitivity and specificity of this PCR
were 74 and 95.8%, respectively, while the positive and negative predi
ctive values were 89.5 and 88.5%, respectively.
