CPT® Code 87143

The CPT® Code 87143 refers to a laboratory procedure known as culture typing, which utilizes advanced analytical techniques such as gas liquid chromatography (GLC) or high pressure liquid chromatography (HPLC). In this procedure, a blood serum sample is first vaporized into a gas form, allowing for the separation and analysis of various substances present in the sample. This method is particularly effective in identifying specific components within the serum that may be indicative of certain conditions or infections. Alternatively, the high pressure liquid chromatography method involves running the liquid sample through a machine under high pressure, which effectively filters and separates the different components for further identification. Both techniques are crucial in clinical diagnostics, providing valuable information that aids in the understanding of a patient's health status and guiding subsequent treatment decisions.
