CPT® Code 86318

CPT® Code 86318 refers to an immunoassay procedure designed to detect the presence of antibodies against infectious agents. This code specifically applies to qualitative or semiquantitative testing methods that utilize a single-step approach, such as reagent strips or dipsticks. The primary purpose of this immunoassay is to identify whether antibodies are present in a patient's sample, indicating exposure to specific infectious agents. The results from this type of testing are typically available within a short timeframe, usually between 5 to 10 minutes, making it a rapid diagnostic tool. Common infectious agents that may be screened using this method include Helicobacter pylori, influenza viruses (types A and B), infectious mononucleosis, respiratory syncytial virus (RSV), and group A streptococcus. This code is distinct from other related codes, such as CPT® Code 86317, which is used for quantitative measurements of antibody levels rather than qualitative detection.
