The most common is a complete blood count (CBC) that measures the number of red and white blood cells, hemoglobin, and platelets. This test helps detect anemia, which can be a sign of scleroderma.
A sedimentation rate (ESR) can also be used to diagnose scleroderma. This test measures the speed at which red blood cells fall to the bottom of a tube and can reveal inflammation in the body.
A C-reactive protein (CRP) test is used to measure the amount of CRP, an inflammatory marker, in the blood. An elevated CRP level may indicate an underlying autoimmune condition such as scleroderma.
A rheumatoid factor (RF) test may also be used to measure the amount of RF in the blood. A high level of RF can suggest the presence of an autoimmune disorder such as scleroderma.
In addition to blood tests, doctors also perform skin biopsies, imaging tests such as x-rays, CT scans and MRI scans, as well as lung function tests to diagnose scleroderma.

Does scleroderma show up in blood work?
Yes, scleroderma can show up in blood work. When you go in for a screening to check for scleroderma, the doctor usually orders a variety of blood tests to check for signs of scleroderma. This includes a complete blood count, a blood chemistry panel, and tests for particular antibodies in your blood.
The blood test for scleroderma looks for antibodies called antinuclear antibodies (ANA) and anti-Scl-70 antibodies, both of which are common in people with the condition. In addition to these tests, your doctor may request additional tests, such as a erythrocyte sedimentation rate (ESR) test and a C-reactive protein (CRP) test, depending on your specific symptoms.
If scleroderma is suspected, your doctor may also recommend a skin biopsy and other tests to confirm the diagnosis.
What labs are abnormal with scleroderma?
Scleroderma is a complex, chronic autoimmune connective tissue disorder, and there are a number of laboratories that may show abnormalities with this condition. Generally speaking, labs that may be abnormal include:
• Erythrocyte sedimentation rate (ESR): This test measures how quickly red blood cells “settle” to the bottom of a test tube, which can help measure overall inflammation in the body. People with scleroderma typically have an elevated ESR.
• Complement levels: These blood proteins help the immune system detect and respond to foreign invaders, but can be reduced in people with scleroderma.
• Autoantibodies: Antibodies are proteins that fight invaders, but in someone with scleroderma, they may attack healthy tissue instead. Tests to measure various autoantibodies associated with scleroderma include anti-nuclear antibody, anti-cardiolipin antibody, and anti-Ro/SSA antibody.
• ANA titer: The antinuclear antibody titer measures the amount of a certain type of autoantibody in the blood, and is typically elevated in people with scleroderma.
• Creatinine & BUN: These tests measure kidney function, and may be elevated in people with scleroderma.
• Platelet count: Because scleroderma affects the small blood vessels of the skin and other organs, it can cause changes in the production of platelets—the cells that help our blood clot. Low platelet counts may indicate problems related to scleroderma.
In some cases, other tests may be ordered as well, such as imaging scans to look for organ changes related to scleroderma or specialized blood tests to measure other changes or antibodies.
How does a doctor check for scleroderma?
A doctor will typically perform a physical examination to check for the signs and symptoms of scleroderma. The examination will usually involve looking for pieces of hardened skin or visible signs of swelling or discoloration in areas such as the hands, face, and extremities.
The doctor may also check range of motion and overall mobility in the joints. In addition, they may use a stethoscope to listen to the heart, as scleroderma often affects the heart and lungs.
A blood test may also be taken to check for certain biomarkers or proteins that are typically elevated in people with scleroderma. The doctor may also order tests such as urine tests, chest x-rays, and other imaging tests such as an MRI, CT scan, or echocardiogram.
Based on the results of these tests, the doctor can make a more accurate diagnosis of the severity and type of scleroderma the person has.
What is the marker for scleroderma?
As it is an autoimmune disorder with a range of symptoms and no known cause. However, there are several tests that may be used to diagnose scleroderma, including: skin biopsy, blood tests to measure levels of certain immune cells, X-rays, CT scans, and ultrasounds to detect any changes in the structure of the organs.
Additionally, doctors may order additional tests such as electromyography (EMG), nerve conduction tests, pulmonary function tests, and other heart tests.
Physicians may also perform or request physical examinations to help diagnose scleroderma. During the physical, the doctor will likely observe the appearance of the skin, feeling for abnormalities in the joints and muscles, and looking for changes in sensation.
A cardiovascular exam may also be carried out to assess the health of the heart and lungs. Physical examination is a good indicator of scleroderma as it can detect changes in the skin, joints, and muscles.
It is important to note that there is no single marker for scleroderma, as this autoimmune disorder changes over time and presents different symptoms in different individuals. The diagnostic tests and physical examinations mentioned above are used to help picture the changes that may occur in the body as a result of scleroderma.
What were your first symptoms of scleroderma?
My first symptoms of scleroderma were a persistent, dry and tight feeling in my skin. At first, I couldn’t really identify what it was and it seemed to come and go. Eventually, it became more and more persistent and I noticed some patches of hard, thick skin on areas like my hands and face.
I also started experiencing some joint and muscle pain and stiffness that was initially attributed to getting older. I had some fatigue, a low-grade fever, and started losing some weight. Eventually, I went to a rheumatologist to get some tests done and was diagnosed with scleroderma.
Which antibody is positive in systemic sclerosis?
Systemic sclerosis (SSc) is an autoimmune disorder characterized by excessive accumulation of collagen in the skin and other organs. This leads to fibrosis, or tissue hardening, that can eventually cause tissue damage.
While there is no cure for SSc, its diagnosis can be aided by presence of certain biomarkers in the blood. One such biomarker is an autoantibody called anti-topoisomerase 1 (anti-Scl-70). Anti-topoisomerase 1 is a specific type of autoantibody known as a high prevalence autoantibody (HPA).
This type of antibody is mainly found in those with systemic sclerosis, and is detected in up to 70% of patients diagnosed with SSc. Furthermore, anti-Scl-70 is a strong indication of active disease, and its presence is associated with a greater risk of disease progression in people with SSc.
In contrast, absence of this antibody is associated with milder forms of the disease. Positive anti-Scl-70 antibody levels indicate that the patient is suffering from systemic sclerosis and can be used to monitor disease activity and progression.
What is Scl 70 blood test?
The Scl-70 blood test, also known as the Antinuclear Antibody (ANA) Scl-70 test or the Topoisomerase I (Scl-70) antibody test, is a medical test used to look for autoimmune diseases such as scleroderma, systemic lupus erythematosus, and mixed connective tissue disease.
It measures the presence and amount of a specific antibody, scleroderma antigen (Scl-70), in the blood. The presence of the antibody implies that the person’s immune system is attacking their own cells, which may be indicative of an autoimmune disorder.
It is typically ordered along with other ANA tests, if there is a suspicion of an autoimmune disorder. Results of the Scl-70 blood test are usually available within 2-3 days after the sample is collected.
Where does scleroderma usually start?
Scleroderma usually starts with a thickening and hardening of the skin, along with areas of inflammation and discoloration. The areas most commonly affected are on the face and hands, along with the arms and legs.
Generally, it will start in one area and possible spread over time to other areas of the body. Additionally, the onset of scleroderma may be accompanied by a range of other symptoms such as fatigue, muscle weakness, swelling of the face, painful joints, and gastrointestinal issues.
In severe cases, organs such as the lungs and heart can be affected. Ultimately, the severity and exact location of the effects will depend upon the type of scleroderma, as there are variations which affect different areas of the body.
Which organ is more involved in scleroderma?
The organ that is most involved in scleroderma is the skin. Scleroderma is a rare autoimmune disease that causes the skin and connective tissue to become hard and thick. This can result in skin tightening, discoloration, and burning or itchy sensations.
It can also cause damage to the blood vessels, lungs, heart, and kidneys. In severe cases, scleroderma can cause organ failure and lead to death. Additionally, scleroderma can cause damage to the gastro-intestinal and musculoskeletal systems which can result in difficulty with swallowing, bloating, and painful joint movements.
People with scleroderma may also experience symptoms including fatigue, depression, and difficulty concentrating. In order to properly diagnose and treat scleroderma, your doctor may perform tests such as chest radiographs, blood tests, and MRI scans.
Treatment options are primarily centered around managing symptoms and may include medications, physical therapies, and lifestyle adjustments.
How do I know if I have systemic scleroderma?
Systemic scleroderma is an autoimmune disorder that affects the body’s connective tissues, causing the skin and organs to thicken and harden. It can have serious consequences on a person’s health. To determine if you have systemic scleroderma, your doctor will perform some tests and ask about your medical history.
Some of the tests your doctor may use to diagnose systemic scleroderma include blood tests to check for antibodies that may be associated with the disease, X-rays and other imaging tests to look for signs of organ damage, and a physical examination to look for signs of hardening and thickening skin.
Your doctor may also order a biopsy of affected skin to look for cellular changes indicative of systemic scleroderma.
Your doctor will also ask questions about your medical history, such as if you have had any other autoimmune disorders, if you have experienced any symptoms of systemic scleroderma, and if you have noticed any changes in the way your skin or organs look or feel.
This can help them determine the best course of treatment for you.
Because systemic scleroderma can have a range of possible symptoms, it can be difficult to diagnose. Your doctor should be able to work with you to best evaluate your condition and determine the most appropriate course of action for you.
What autoimmune diseases cause positive ANA?
Autoimmune diseases are those in which the body’s immune system attacks its own cells, tissues, and/or organs, causing damage and dysfunction. A positive result on an antinuclear antibody (ANA) test means that the body may have one of the diseases classified in the family of autoimmune disorders.
Some of the most common autoimmune diseases associated with a positive ANA result include systemic lupus erythematosus (lupus), rheumatoid arthritis (RA), Sjogren’s syndrome, scleroderma, polymyositis, dermatomyositis, autoimmune hepatitis, and mixed connective tissue diseases.
In lupus, autoantibodies are typically found to be directed against two nuclear antigens – the ribonucleoprotein Ro/SSA and the double-stranded DNA antigen (dsDNA). In other autoimmune diseases, the antibodies may be directed towards other nuclear or cytoplasmic antigens, including histones, Sm antigen, and Jo-1 antigen.
It is important to note that a positive ANA result does not necessarily diagnose one of these autoimmune diseases; further tests may be required to confirm the diagnosis.
