What does LC mean on lab report?
Liquid chromatography–tandem mass spectrometry (LC–MS/MS) has superior specificity compared to immunoassays and is also able to measure several analytes simultaneously.
What is LC-MS lab test?
Liquid chromatography mass spectrometry (LC-MS) is an analytical chemistry laboratory technique for identification, quantitation and mass analysis of materials. Similar to HPLC/UPLC, a pump is used to provide a continuous flow of a solvent into which a dissolved sample is introduced.
What is LC-MS MS used for?
Liquid chromatography-mass spectrometry (LC–MS) is a powerful analytical technique used for separation, identification, and quantification of both unknown and known compounds as well as to elucidate the structure and chemical properties of different molecules.
What is MRM in LCMS?
MRM stands for Multiple Reaction Monitoring.
What is a MRM transition?
The observed m/z ratio of a peptide and its corresponding product ion m/z ratio are referred to as a MRM “transition.” Consequently to monitor a protein of interest, it must be known in advance which transition is most suitable.
What is the LC/MS/MS assay?
The LC/MS/MS assay will provide quantitative measurement of Tg in the presence of Tg Ab. Please visit our Clinical Education Center to stay informed on any future publications, webinars, or other education opportunities. This test was developed and its analytical performance characteristics have been determined by Quest Diagnostics.
What is the LC/MS-MS Test number for testosterone?
Testosterone, Free, Direct With Total Testosterone, LC/MS-MS TEST:070195 Test number copied CPT:84402; 84403 PrintShare Include LOINC® in print
Which laboratories are using LC-MS/MS?
Drug/Toxicology and Biochemical Genetics/Newborn Screening laboratories were at the vanguard of clinical LC-MS/MS use, but have been eclipsed by Endocrine laboratories. In USA reference/referral laboratories, most steroids and biogenic amines are now assayed by LC-MS/MS, and the technology has started to penetrate into smaller laboratories.
What is thyroglobulin LC MS?
Thyroglobulin, LC/MS/MS – Measurement of thyroglobulin (Tg) is useful in the detection of residual or recurrent thyroid cancer. Many individuals develop auto-antibodies to Tg (Tg Ab) and the presence of Tg Ab interferes with the measurement of immunoassay Tg.
