| description | Real-time polymerase chain reaction (PCR) assay for the rapid detection of the toxin B gene (tcdB) of Clostridium difficile. Fecal C. difficile toxin testing can aid the diagnosis of C. difficile-associated diarrhea in hospitalized patients. | |
| status | ACTIVE | |
Fully-Specified Name | ||
| component | Clostridioides difficile toxin B tcdB gene B = Buccal | |
| 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 | Stool = Stool = Fecal | |
| scale | Ord = Ordinal: Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive. | |
| method | Probe.amp.tar | |
