77959-5
LaboratoryYellow fever virus ns5 gene [Presence] in Cerebral spinal fluid by NAA with non-probe detection
Definition
This assay comprises qRT-PCR targeting the ns5 gene in the yellow fever backbone followed by melt curve analysis, which identifies DNA fragments with different nucleotide compositions based on their unique melting temperature. [PMID: 18501437] CSF testing is indicated for suspected adverse neurological reactions to the vaccine against yellow fever. Genome detection of CSF yellow fever vaccine in this context is considered diagnostic. In suspected patients, detection of antibodies against yellow fever in CSF should also be requested.
