What are the methods for checking melanoma

Many patients with melanoma are very confused when they are diagnosed, because they know too little about melanoma. Many people don't know what are the methods of melanoma examination? What are the examination items? So even if they go to the hospital, they are still confused. In this regard, we specially consulted relevant experts to see what are the examination methods of melanoma introduced by experts?

Experts say that the high-risk group for melanin is the middle-aged and elderly, and the incidence rate in men is higher than that in women. The disease sites are mostly concentrated in the patient's lower limbs and feet, followed by the human body's trunk, upper limbs, and head and neck. The routine examination methods for melanoma are as follows:

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 double PAP immunoenzyme: When the dilution of the antiserum is 1:400, 81.24% 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.
