CPT® Code 87634

The CPT® Code 87634 refers to a laboratory test specifically designed for the detection of the infectious agent known as respiratory syncytial virus (RSV) through the use of nucleic acid analysis, which can involve either DNA or RNA. Respiratory syncytial virus is a prevalent respiratory pathogen that typically manifests as cold-like symptoms in adults and older children. However, it poses a significant risk to vulnerable populations, particularly infants under one year of age and the elderly, as it is a leading cause of severe lung infections and airway inflammation in these groups. The test utilizes an amplified probe technique, which enhances the sensitivity of the assay by exponentially increasing the quantity of the target RSV DNA or RNA sequence. This amplification process is most commonly achieved through methods such as polymerase chain reaction (PCR) or reverse transcriptase polymerase chain reaction (RT-PCR). Following amplification, the resultant replicated sequences are identified using DNA probes that are labeled with either fluorescent or chemiluminescent markers, ensuring that they bind specifically to the target sequence of RSV. This precise detection method is crucial for accurate diagnosis and management of RSV infections.
