What is the Origin of LC-MS/MS?

This is a technical term originating from analytical chemistry and laboratory medicine. LC stands for Liquid Chromatography, a separation science technique, and MS/MS stands for Tandem Mass Spectrometry, a powerful detection method. The development of this technology revolutionized the precision of hormonal diagnostics.

What is the Mechanism of LC-MS/MS?

The process begins with liquid chromatography separating the complex mixture of compounds in the sample based on their physicochemical properties. The separated components then enter the first mass spectrometer (MS1) for ionization and selection of the target molecule. These ions are fragmented, and the second mass spectrometer (MS2) detects and quantifies the specific fragments, providing definitive molecular identification and highly accurate concentration data. This dual-stage detection ensures both sensitivity and specificity in complex biological matrices.

LC-MS/MS

Meaning

An advanced analytical technique, Liquid Chromatography-Tandem Mass Spectrometry, utilized for the highly sensitive and specific quantification of molecules, including hormones and their metabolites, in biological samples. This method separates components via liquid chromatography before precisely identifying and measuring them using two stages of mass spectrometry. Clinically, LC-MS/MS provides superior accuracy and reduced interference compared to older immunoassay methods, especially for low-concentration steroid hormones. It is considered the gold standard for many endocrine measurements.
