CPT® Code 86707

The CPT® Code 86707 refers to a laboratory test specifically designed to measure the presence of Hepatitis Be-antibodies (HBeAb) in the blood. HBeAb is an antibody that the body produces in response to the Hepatitis Be-antigen, which is associated with the Hepatitis B virus (HBV). This antibody can remain elevated for several years after an individual has recovered from an acute HBV infection, indicating a potential long-term immune response. The measurement of HBeAb levels is crucial for several clinical purposes, including assessing the infectivity of individuals who are carriers of HBV, monitoring the infection status of patients with chronic HBV infections, and evaluating the immune response in patients undergoing antiviral therapy for chronic HBV. In clinical practice, the presence of HBeAb, particularly in conjunction with negative HBV DNA levels in the serum, suggests that the individual may have a state of viral inactivity and low infectivity, which is important for determining the risk of transmission to others. Conversely, the presence of HBV DNA in the serum indicates active viral replication, which correlates with a higher risk of infectivity. The test is performed by obtaining a blood sample through venipuncture, and the serum is analyzed using a qualitative enzyme immunoassay, a method that allows for the detection of specific antibodies in the blood. This test plays a vital role in the management and treatment of patients with HBV, guiding clinical decisions and monitoring disease progression.
