Non Nucleic Acid–Based Identification Methods for Infectious Disease
Chromatographic methods
Microbial components or products are separated and identified using high-performance liquid chromatography (HPLC) or gas chromatography. Usually, identification is by comparison of an organism’s fatty acids to a database. Chromatographic methods can be used to identify aerobic and anaerobic bacteria, mycobacteria, and fungi. Test accuracy depends on the conditions used to culture the specimen and the quality of the database, which may be inaccurate or incomplete.
