Understanding Lab Tests for Skin Lesions
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Skin lesions are abnormal areas of skin that differ in appearance from the surrounding tissue. These can include bumps, sores, rashes, or changes in skin color. While skin lesions are primarily diagnosed through visual examination and sometimes biopsy, blood testing plays a valuable supporting role in identifying potential underlying causes.
Recommended Test
Heavy Metals Panel, Blood
This test measures levels of various heavy metals in the blood, including arsenic. Chronic exposure to arsenic and other heavy metals can cause distinctive skin lesions and changes in skin pigmentation. Testing helps identify whether toxic metal exposure might be contributing to unexplained skin changes.

The Role of Blood Testing in Skin Lesion Assessment
There is no single blood test that can diagnose skin lesions themselves. However, blood testing is fundamental for investigating potential systemic causes, toxic exposures, or underlying conditions that may manifest as skin changes. This comprehensive approach helps healthcare providers determine the most appropriate treatment plan.
When to Consider Heavy Metal Testing
Heavy metal testing may be particularly valuable when skin lesions appear alongside other symptoms, occur in areas with known environmental contamination, or when conventional dermatological evaluation doesn't provide clear answers. Early detection of metal toxicity can guide appropriate treatment and prevent further exposure.
