Blood tests or other laboratory investigations may be recommended to rule out underlying conditions that could be contributing to the skin condition. Overall, a combination of clinical assessment, medical history review, and possibly laboratory tests are utilized to diagnose Digitate dermatosis accurately.

Clinical examination of skin lesions on the fingers and toes.
Dermoscopy to assess the morphology and patterns of the skin lesions.
