Common Language Description

The CPT® Code 80172 refers to a laboratory test specifically designed to measure the levels of gold in the blood, which is also known as gold sodium thiomalate. This substance is classified as a disease-modifying antirheumatic drug (DMARD) and is commonly used in the treatment of severe rheumatoid arthritis, psoriatic arthritis, and certain types of arthritis that may present with an enlarged spleen and elevated white blood cell counts. The test involves obtaining a blood sample through a procedure known as venipuncture, which is a separate reportable service. Once the blood sample is collected, the serum is analyzed using a technique called graphite furnace atomic absorption spectroscopy, a highly sensitive method that allows for precise measurement of trace elements like gold in the serum. This test is crucial for monitoring the therapeutic levels of gold in patients undergoing treatment with this medication, ensuring that the drug is effective while minimizing potential toxicity.

1. Indications

The blood test for gold levels (CPT® Code 80172) is indicated for patients who are undergoing treatment with gold sodium thiomalate, particularly those diagnosed with the following conditions:

  • Severe Rheumatoid Arthritis - A chronic inflammatory disorder affecting joints, leading to pain and disability.
  • Psoriatic Arthritis - An inflammatory arthritis associated with psoriasis, characterized by joint pain and swelling.
  • Arthritis with Enlarged Spleen - Conditions where arthritis is accompanied by splenomegaly, which may indicate systemic involvement.
  • Elevated White Blood Cell Count - A condition that may suggest an underlying inflammatory or infectious process, warranting monitoring during treatment.

2. Procedure

The procedure for testing gold levels in the blood involves several key steps that ensure accurate results. First, a healthcare professional will perform a venipuncture, which is the process of puncturing a vein to obtain a blood sample. This step is critical as it allows for the collection of serum, which is necessary for the subsequent analysis. The blood is typically drawn from a vein in the arm using a sterile needle and collection tube. Once the blood sample is collected, it is processed to separate the serum from the cellular components. The serum is then subjected to graphite furnace atomic absorption spectroscopy, a sophisticated analytical technique that measures the concentration of gold in the serum. This method is known for its sensitivity and precision, making it suitable for detecting low levels of gold, which is essential for monitoring patients receiving gold therapy.

3. Post-Procedure

After the blood sample has been collected and sent for analysis, there are generally no specific post-procedure care requirements for the patient. However, it is important for healthcare providers to monitor the patient for any potential side effects related to gold therapy, especially if the test results indicate elevated levels of gold. Patients may be advised to report any unusual symptoms or side effects they experience following their treatment. Additionally, follow-up appointments may be scheduled to discuss the test results and adjust treatment plans as necessary based on the findings.
