What tests should be done for melanoma?

1. Scleral transillumination test: This method has great value in the identification and diagnosis of melanoma. If there are inflammatory lesions, macular discoid degeneration, choroidal metastatic carcinoma and choroidal hemangioma, light can be transmitted. However, if choroidal melanoma occurs, light will generally not be transmitted.

2. Pigmentogen test: Melanogen is oxidized after being eliminated by the kidneys, and the patient's urine will be dark brown, which is called black urine. If ferric chloride, sulfuric acid, and potassium dichromate are added to black urine, it will promote its oxidation. If sodium nitrate is added, the urine will appear purple. If acetic acid is added first and then sodium chloride is added, the urine will appear blue.

3. Labeling test using Vacca dual PAP immunoenzyme: When the dilution of the antiserum is 1:400, 82.14% of the positive reactions will occur.

The above is an introduction to several methods of melanoma examination. If you want to check for melanoma, you can use the methods introduced above. However, it should be noted that in order to obtain the most accurate test results and prevent misdiagnosis, it is recommended that patients choose a regular, large hospital for examination. If melanoma is confirmed, patients should continue to stay in the hospital for observation and treatment, and should not take medication without authorization to avoid worsening of the condition.
