CPT® Code 85652

The CPT® Code 85652 refers to the automated measurement of the erythrocyte sedimentation rate (ESR), a laboratory test that assesses the rate at which red blood cells (erythrocytes) settle in a vertical column of anticoagulated blood over a specified period, typically one hour. This test is a non-specific indicator of inflammation in the body and is often utilized to help identify various medical conditions associated with both acute and chronic inflammatory processes. Commonly, the ESR test is performed alongside other diagnostic tests to provide a more comprehensive understanding of the underlying causes of inflammation, such as infections, cancers, and autoimmune disorders. In the automated version of the test, a blood sample is first collected and treated with an anticoagulant to prevent clotting. The sample is then aspirated and introduced into an automated system designed to measure the sedimentation rate. The automation of this process enhances efficiency and accuracy, providing a reading of the sedimentation rate after the designated time has passed. It is important to note that while the basic principle of measuring the distance that erythrocytes fall remains the same, the specific techniques and equipment used can vary among different automated systems. This automation streamlines the testing process, allowing for quicker results and reducing the potential for human error in manual measurements.
