Physical Examination: The First Step

Your doctor will start with a thorough physical exam, looking for skin changes, especially on your hands and face. They'll check for Raynaud's phenomenon and look at your fingernails under a microscope to examine tiny blood vessels. This is called nailfold capillaroscopy.

Blood Tests: Searching for Clues

Several blood tests are typically ordered. These include tests for antinuclear antibodies (ANA) and specific antibodies associated with systemic sclerosis, like anti-Scl-70 and anticentromere antibodies. Other tests may check for inflammation, muscle damage, or organ function.
Systemic sclerosis is a chronic connective tissue disease often characterized by skin thickening and involvement of internal organs. Diagnosis involves a combination of physical examinations, blood tests, and imaging studies.

Imaging and Organ Function Tests

Depending on your symptoms, your doctor may order additional tests. These might include chest X-rays or CT scans to check your lungs, echocardiograms to assess your heart, or tests to evaluate your digestive system. Pulmonary function tests are often done to check how well your lungs are working.

FAQs

Is a skin biopsy necessary?

Usually not, but it may be done in some cases to rule out other conditions.

How long does diagnosis take?

Are these tests painful?

Most are painless, though blood draws may cause brief discomfort.

Will I need to repeat tests?

Yes, some tests may be repeated to monitor disease progression over time.

Putting the Pieces Together

While the diagnostic process can seem overwhelming, each test provides valuable information to guide your care.
