Tests and diagnosis
By Mayo Clinic staffYour doctor may conduct the following tests:
- Blood tests. People with scleroderma usually have elevated blood levels of certain antibodies produced by the immune system.
- Tissue sample. Your doctor may remove a small tissue sample (biopsy) of your affected skin to be examined in the laboratory for abnormalities.
- Skin assessment. Your doctor ideally evaluates the condition of your skin in 17 specific areas to determine the level of skin involvement, which provides a clue to the likelihood that you also have life-threatening changes happening to internal organs.
Based on the outcome of your initial evaluation, your doctor may also recommend other diagnostic tests to identify any lung, heart, kidney or gastrointestinal complications accompanying scleroderma.
