CPT® Code 86625

The CPT® Code 86625 refers to a laboratory test specifically designed to measure antibodies against Campylobacter, a type of spiral-shaped bacteria known to cause gastrointestinal infections in both humans and animals. This test is crucial for diagnosing infections that may lead to symptoms such as diarrhea, which can often be bloody, along with nausea, vomiting, abdominal pain, and fever. Campylobacter infections are particularly prevalent during the summer months and are typically characterized by isolated and sporadic outbreaks. The primary mode of transmission is through the ingestion of raw or undercooked meat and poultry, as well as foods that have been contaminated by these sources. Additionally, unpasteurized dairy products, contaminated drinking water, and contact with infected household pets can also result in human infections. A positive result for Campylobacter jejuni IgG antibodies indicates either a current or past infection with this bacterium. To perform this test, a blood sample is collected, which is reported separately through a venipuncture procedure. The serum obtained from the blood sample is then analyzed using a semi-quantitative indirect fluorescent antibody technique, allowing for the detection and measurement of the specific antibodies present in the patient's serum.
