Official Description

Nuclear Matrix Protein 22 (NMP22), qualitative

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 86386 refers to a qualitative screening test for Nuclear Matrix Protein 22 (NMP22). This test is specifically utilized in patients presenting with hematuria, which is the presence of blood in the urine. The primary purpose of the NMP22 test is to assist healthcare providers in distinguishing between hematuria caused by bladder cancer and hematuria resulting from other non-malignant conditions. NMP22 is a protein that resides within the cell nucleus, and its levels can be indicative of malignancy. In cases of bladder cancer, malignant neoplasms lead to an increase in intracellular NMP22 levels, which subsequently results in the shedding of this protein into the urine. To perform the test, a urine sample is collected from the patient, and a specialized test kit designed for NMP22 is employed to detect the presence or absence of the protein in the urine. Additionally, the test estimates the concentration of NMP22, with a level exceeding 7 being suggestive of a potential bladder malignancy. This screening test plays a crucial role in the early detection and diagnosis of bladder cancer, thereby facilitating timely intervention and management.

1. Indications

The NMP22 qualitative screening test is indicated for patients who present with hematuria. The specific conditions or symptoms that warrant this test include:

  • Hematuria The presence of blood in the urine, which may be a symptom of various underlying conditions, including bladder cancer.

2. Procedure

The procedure for conducting the NMP22 qualitative screening test involves several key steps, which are outlined as follows:

  • Step 1: Urine Sample Collection A urine sample is obtained from the patient. This sample is critical as it will be analyzed for the presence of Nuclear Matrix Protein 22 (NMP22). Proper collection techniques must be followed to ensure the integrity of the sample.
  • Step 2: Test Kit Preparation A test kit specifically designed for the detection of NMP22 is prepared. This kit contains the necessary reagents and materials required to perform the qualitative analysis of the urine sample.
  • Step 3: Testing for NMP22 The urine sample is then subjected to the test kit, which will identify the presence or absence of NMP22 in the urine. The test also estimates the concentration of the protein present in the sample.
  • Step 4: Interpretation of Results After the testing process, the results are interpreted. A concentration level of NMP22 greater than 7 is considered suggestive of bladder malignancy, indicating the need for further diagnostic evaluation.

3. Post-Procedure

Post-procedure care following the NMP22 qualitative screening test typically involves monitoring the patient for any immediate reactions to the test. Additionally, healthcare providers will discuss the results with the patient, particularly if the NMP22 level is elevated. If the test suggests a potential bladder malignancy, further diagnostic procedures, such as cystoscopy or imaging studies, may be recommended to confirm the diagnosis and determine the appropriate course of action. It is essential for patients to follow up with their healthcare provider to discuss the implications of the test results and any necessary next steps in their care.
