CPT® Code 87280

The CPT® Code 87280 refers to a laboratory test specifically designed for the detection of the respiratory syncytial virus (RSV) antigen using an immunofluorescent technique. This test is crucial for identifying RSV, which is known to cause significant respiratory infections, particularly in vulnerable populations such as infants, young children, the elderly, and individuals with pre-existing lung or heart conditions. The common presentation of RSV infection can range from mild upper respiratory symptoms to severe conditions like bronchiolitis and pneumonia. The test is performed on samples obtained from the nasopharynx, either through a swab or aspirate, allowing for the direct detection of the virus's antigens. The immunofluorescent technique involves treating the sample with a reagent that contains antibodies specific to RSV, which, when examined under an epifluorescence microscope, will reveal a color change if RSV antigens are present. This method is noted for its rapid results, although it may have lower sensitivity compared to more advanced techniques such as reverse transcription-polymerase chain reaction (RT-PCR). Understanding the implications of RSV infections and the utility of this test is essential for timely diagnosis and management of affected patients.
