| name | Yellow fever virus ns5 gene [Presence] in Cerebral spinal fluid by NAA with non-probe detection | ||
| description | 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. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Yellow fever virus ns5 gene | ||
| property | PrThr = Present or threshold: The Property PrThr stands for “Presence or Threshold”, meaning either a) the actual presence or absence of an analyte, or b) that the amount of analyte detected is over some predetermined threshold. | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | CSF = Cerebral spinal fluid | ||
| scale | Ord = Ordinal: Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive. | ||
| method | Non-probe.amp.tar | ||
Additional Names | |||
| short name | YFV ns5 gene CSF Ql NAA+non-probe | ||

| last updated | 2.63 | ||
| last change type | MIN - change to field other than name | ||
| change reason | Changed Method from "Melt.amp.tar" to "Non-probe.amp.tar", which includes other non-probe based detection methods while still distinguishing from probe-based methods.; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016. | ||
