CPT® Code 83670

The CPT® Code 83670 refers to the measurement of leucine aminopeptidase (LAP) levels through a blood test. LAP is an enzyme that plays a crucial role in the maintenance of cells and is primarily found in the liver and small intestine. This enzyme is involved in various metabolic processes, and its levels in the blood can provide valuable insights into liver function and overall health. Elevated levels of LAP may suggest liver damage or dysfunction, which can arise from several conditions, including hepatitis, cirrhosis, and tumors. It is important to note that elevated LAP levels can also be a normal physiological finding during the third trimester of pregnancy, indicating that context is essential when interpreting test results. The test is performed by obtaining a blood sample through venipuncture, which is a procedure that may need to be reported separately. The serum obtained from the blood sample is then analyzed using quantitative spectrophotometry, a method that measures the concentration of the enzyme in the serum, providing precise and reliable results for clinical assessment.
