HMB-45 Ag
Detects HMB-45 protein in tissue samples using specialized staining techniques.
Why This Biomarker Matters
HMB-45 expression helps confirm melanoma diagnosis and differentiate it from benign skin lesions. This is critical for appropriate cancer treatment planning.
Overview
HMB-45 is a protein marker found in melanoma and other pigmented tumors. This immunohistochemical stain detects HMB-45 antigen in tissue samples, helping pathologists diagnose melanoma and distinguish it from benign moles or other skin cancers. A positive stain supports melanoma diagnosis and can guide treatment decisions. This test is performed on biopsied tissue under a microscope by trained pathologists as part of cancer diagnosis and staging.
