77666-6Methicillin resistance mecA mRNA [Presence] by FISH in Positive blood cultureActive

Term Description

This term was created for, but is not limited in use to, the AdvanDx mecA XpressFISH® assay, which is intended for the detection of mecA mRNA on smears from blood cultures found to be solely positive for Staphylococcus aureus by the Staphylococcus QuickFISH BC assay. Detection of mecA mRNA implies the presence of methicillin-resistant Staph aureus (MRSA), and absence of mecA mRNA implies the presence of methicillin-susceptible Staph aureus (MSSA).

Part Description

LP62864-1   FISH
FISH (fluorescence in situ hybridization) is a cytogenetic technique used to detect and localize the presence or absence of specific DNA sequences on chromosomes. FISH uses fluorescent probes that bind to only those parts of the chromosome with which they show a high degree of sequence similarity. Fluorescence microscopy can be used to find out where the fluorescent probe bound to the chromosomes. FISH is often used for finding specific features in DNA for use in genetic counseling, medicine, and species identification. FISH can also be used to detect and localize specific mRNAs within tissue samples. In this context, it can help define the spatial-temporal patterns of gene expression within cells and tissues.

Change Reason
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.; Removed parentheses around gene name in Component based on the current LOINC model.
Order vs. Observation
Both
