CPT® Code 87140

The procedure described by CPT® Code 87140 involves the culture and typing of a specimen using the immunofluorescent method. This technique is utilized to identify specific antisera present in a blood serum sample. During the process, a sample of blood serum is first stained with a fluorescent dye, which allows for the visualization of the different antisera when examined under a microscope. The use of fluorescent dyes enhances the contrast of the antisera against the background, making it easier to distinguish between various types. This method is particularly valuable in clinical laboratories for diagnosing infections and determining the presence of specific antibodies in the serum, which can be critical for patient management and treatment decisions.
