What is the tumor marker for melanoma?

Is there a tumor marker for melanoma?

What blood test indicates melanoma?

Blood tests. Blood tests aren’t used to diagnose melanoma, but some tests may be done before or during treatment, especially for more advanced melanomas. Doctors often test blood for levels of a substance called lactate dehydrogenase (LDH) before treatment.

Does melanoma cause high white blood cell count?

Screening laboratory studies may show an elevated white blood cell count (WBC) at diagnosis or during the treatment of melanoma. This finding may be caused by infection, bone marrow metastasis, or concomitant corticosteroid administration.
