CPT® Code 82390

The CPT® Code 82390 refers to the measurement of ceruloplasmin levels in the blood. Ceruloplasmin is a crucial protein that plays a significant role in the transport of copper molecules throughout the bloodstream and is also involved in iron metabolism. This test is particularly important in the diagnostic process for conditions such as Wilson disease, a genetic disorder that leads to excessive copper accumulation in the body, and copper deficiency, which can result in various health issues. The ceruloplasmin test is typically ordered alongside other blood and urine tests that assess copper levels to provide a comprehensive evaluation of a patient's copper metabolism. To perform this test, a blood sample is collected through a procedure known as venipuncture, which is separately reportable. The analysis of the serum or plasma is conducted using a method called quantitative immunoturbidimetry, which allows for precise measurement of ceruloplasmin concentrations in the sample.
