Useful for evaluating the cause of elevated homocysteine levels, sometimes to help determine your risk of thrombosis or premature cardiovascular disease (CVD).
Useful for determination of postimmunization immune response of individuals to the mumps vaccine and/or documentation of previous infection with mumps virus in an individual with no previous record of immunization to mumps virus
Useful for the detection and identification of Mycobacterium species, Nocardia species, and other aerobic actinomycetes. Identification is performed using the Hologic/GenProbe AccuProbes for selected Mycobacterium species, matrix assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry, or 500-base pair 16S rRNA gene sequencing. M tuberculosis complex species identification can be done upon request using rapid PCR targeting the regions of difference (RD) genomic areas.
