Summary:
- This article describes a new method for detecting and quantifying the levels of various chemical compounds in biological samples, such as blood or urine.
- The method uses a technique called liquid chromatography-tandem mass spectrometry (LC-MS/MS) to separate and identify different molecules based on their unique mass and chemical properties.
- This approach allows for the precise measurement of a wide range of substances, including drugs, hormones, and other biomarkers, which can provide valuable insights into a person's health and physiological state.
