CPT® Code 87147

The CPT® Code 87147 refers to a laboratory procedure known as culture typing using an immunologic method, excluding immunofluorescence techniques. This procedure involves the identification and grouping of different antisera present in a blood sample. In simpler terms, it is a method used to determine the specific types of antibodies in a patient's blood, which can be crucial for diagnosing various infections or immune responses. The process typically involves the use of agglutination grouping, where the blood sample is mixed with specific antisera that react with particular antigens present on the surface of pathogens or cells. This reaction helps in identifying the presence of specific antibodies, thereby allowing healthcare professionals to understand the patient's immune status or the type of infection they may be dealing with. The accurate identification of these antibodies is essential for guiding treatment decisions and ensuring appropriate patient care.
