Abstract
Disclosed are methods, systems, and computer program products for using liquid chromatography/tandem mass spectrometry (LC-MS/MS) for the analysis of endogenous biomarkers, such as PGD2, in a biological sample. More specifically, the methods, systems, and computer program products are described for detecting and quantifying the amount of an PGD2 in a sample. The quantitative analysis may be helpful in making clinical diagnoses.
Claims18
A method for determining the presence or amount of PGD2 in a biological sample by tandem mass spectrometry, comprising:
- (a) obtaining a sample from a subject;
- (b) performing liquid chromatography to purify the sample;
- and
- (c) measuring the PGD2 by tandem mass spectrometry.
A computer-program product tangibly embodied in a non-transitory machine-readable storage medium, including instructions configured to cause one or more computers to perform actions to measure the presence or amount of PGD2 in a biological sample comprising at least one of the following steps:
- (a) obtaining a biological sample from a subject;
- (b) performing liquid chromatography;
- and
- (c) measuring PGD2 by tandem mass spectrometry.
