What blood tests show scleroderma?Antinuclear antibody (ANA) testing is the most important blood test to screen for scleroderma and other connective tissue diseases.
What labs are abnormal with scleroderma?Blood tests: Elevated levels of immune factors, known as antinuclear antibodies, are found in 95% of patients with scleroderma. Although these antibodies are also present in other autoimmune diseases such as lupus, testing for them in potential scleroderma patients is helpful in assisting with an accurate diagnosis.
Can a blood test detect scleroderma?A blood test alone cannot diagnose scleroderma. Depending on the clinical situation, additional tests may be done, such as: Pulmonary function tests or breathing tests to measure how well the lungs are working. CT chest scan may also be ordered to evaluate the extent of lung involvement.
What blood tests are positive with scleroderma?Blood Changes
Approximately 95% of people with systemic scleroderma have a positive antinuclear antibody (ANA) test, but so do people with other autoimmune diseases (97% of people with lupus, as an example). People with localized scleroderma usually have negative ANA.
How can scleroderma be detected?To diagnose scleroderma, a doctor usually begins by asking you about your symptoms, health, and medical history.

What is Scl 70 on a blood test?The presence of Scl-70 antibodies (also referred to as topoisomerase I, topo-I or ATA) is considered diagnostic for systemic sclerosis (SSc).
Is it difficult to diagnose scleroderma?Because scleroderma can take so many forms and affect so many different areas of the body, it can be difficult to diagnose. After a thorough physical exam, your doctor may suggest blood tests to check for elevated levels of certain antibodies produced by the immune system.
What is the pinch test for scleroderma?“In using a skin scoring system, the physician pinches various parts of the patient's body to test for thickness. The less skin that can be pinched equals a higher score in diagnosing scleroderma,” says Feghali-Bostwick.
Can scleroderma cause low iron levels?Conclusions Unexplained iron deficiency is frequent in scleroderma patients and a significant number of these patients do not have frank anaemia. Female sex and longer disease duration is associated with iron deficiency.

How fast does scleroderma progress?In our cohort, 56% of observed progression occurred within 5 years since the first non-Raynaud symptom. While progression in skin involvement occurred more frequently in early disease, the proportion of patients with lung, heart or GI progression was relatively stable over time.
Can you have scleroderma without Raynaud's?Most people diagnosed with Raynaud's will not develop scleroderma, which only affects 0.1% of everyone who has Raynaud's.
