CPT® Code 86671

The CPT® Code 86671 refers to a laboratory test that is specifically designed to measure antibodies against fungi that are not classified elsewhere. This test is crucial for diagnosing certain conditions related to fungal infections and can provide valuable information in the context of various clinical scenarios. The procedure involves obtaining a blood sample through a process known as venipuncture, which is a standard method for collecting blood for laboratory analysis. The test primarily focuses on detecting specific antibodies, such as IgG and IgA, against the fungus Saccharomyces cerevisiae, utilizing a semi-quantitative enzyme-linked immunosorbent assay (ELISA) technique. This particular test is significant in differentiating between ulcerative colitis and Crohn's disease, especially in patients who present with symptoms indicative of inflammatory bowel disease. Additionally, CPT® Code 86671 encompasses the testing of serum for antibodies against other fungi, including Trichophyton rubrum, Stachybotrys chartarum/atra, and Sporothrix, employing various quantitative immunoassay methods. The results of this test can aid healthcare professionals in making informed decisions regarding diagnosis and treatment options for patients with suspected fungal infections or related conditions.
