CPT® Code 87285

The CPT® Code 87285 refers to a specific laboratory test that detects the presence of the infectious agent Treponema pallidum, which is the bacterium responsible for causing syphilis. This test employs an immunofluorescent technique, a method that utilizes fluorescently labeled antibodies to identify the antigen associated with T. pallidum in a specimen. Syphilis is classified as a sexually transmitted disease (STD) and can have serious health implications if left untreated. The test is particularly significant in diagnosing primary syphilis, where a characteristic sore known as a chancre forms at the site of infection. In certain cases, such as when congenital syphilis is suspected, tissue samples from the umbilical cord may also be analyzed. The importance of this test is underscored by the potential consequences of undiagnosed syphilis during pregnancy, which can lead to severe outcomes for the infant, including stillbirth or immediate postnatal death. Additionally, untreated infants may face long-term developmental challenges. The immunofluorescent antigen detection process involves scraping the suspicious lesion to collect a specimen, followed by the application of a specific reagent that binds to the T. pallidum antigen. After incubation, the specimen is examined under a fluorescence microscope, where positive results are indicated by the appearance of bright green or orange-yellow fluorescence, signifying successful antigen-antibody binding.
