Term Description

The quantitative cross/cycle threshold (Ct) value may be reported for real-time PCR-based assays. The value is defined by the number of PCR cycles required for the fluorescent signal of a given product (targeted RNA) to cross the threshold (i.e. exceed background level). In general, the lower the Ct value, the greater the amount of targeted nucleic acid and vice versa. The interpretation (e.g. positive, negative, indeterminate) is determined based on a cut-off value.

Part Description

LP16864-8   Enterovirus
Enteroviruses are small, non-enveloped, single stranded RNA viruses in the picornavirus family and include coxsackievirus, rhinovirus, echovirus, and poliovirus species. They are the most common viral pathogen worldwide, and clinical manifestations range from mild, cold-like symptoms to severe infections, including encephalitis, aseptic (viral) meningitis, and myocarditis. Enterovirus infection has also been associated with the onset of type I diabetes mellitus. PMID: 23764548 Source: Regenstrief LOINC, PMID: 23764548
