Why is the Test Performed?

Malignant melanoma is a cancerous tumor of the skin cells that produce pigment. This disease is usually visible on the skin, but if the malignant cells metastasize to internal areas of the body, you may never see the cancer.

If the skin cell tumors are growing within the body (especially within the liver), melanin may be produced in sufficient quantities to be present in the urine.

This test measures the absence or presence of melanin in the urine.
