What's this test for?

This test is ideal if you're experiencing joint pain, skin thickening or tightening, unexplained muscle weakness, or symptoms of Raynaud's phenomenon like fingers turning white or blue in the cold. It helps check for signs of systemic sclerosis or overlapping connective tissue conditions that can cause these symptoms. It's often used when your symptoms overlap between skin, muscle, and joint issues and a clearer answer is needed.

What's included in this test?

This test looks for a specific autoantibody in your blood called PM/Scl-100. Autoantibodies are proteins your immune system makes that mistakenly target your own tissues, and finding this particular one can point toward systemic sclerosis or overlap conditions between scleroderma and myositis. Detecting it helps clarify a diagnosis when symptoms cross over between different connective tissue conditions.

What happens after I get my results?

Your results will show up in your account with the normal range explained so you know exactly what your value means. If your result is outside the normal range, the report will explain what that could indicate and whether retesting or additional evaluation makes sense; if a result looks dangerously abnormal, seek medical care promptly. You can download a standard lab report directly from your account at any time. You'll also be able to track this result over time using the trends feature if you test again in the future.

How can I naturally support connective tissue and immune health?
Eating an anti-inflammatory diet rich in fruits, vegetables, and omega-3 fatty acids (like fish or flaxseed) may help support your immune system and reduce inflammation. Gentle regular movement, like stretching or swimming, can help keep joints and skin more flexible. Managing stress through sleep, relaxation techniques, and avoiding smoking are also known to support overall immune balance. These steps don't replace medical treatment but can be helpful alongside it.
When will I get my results?
Results are typically available within about 7 days after your sample is processed at the lab. You'll get a notification once they're ready to view securely in your account. If it takes a bit longer, that can happen if additional confirmation testing is needed.
Who should consider this test?
This test is a good option for adults with unexplained skin tightening, joint pain, muscle weakness, or Raynaud's-type symptoms where fingers or toes change color in the cold. It's also useful if you have a family history of autoimmune or connective tissue disease and want to check for early markers. People already diagnosed with a related condition may also use it to clarify whether an overlap syndrome is present.
What symptoms indicate I may need this test?
Common symptoms include skin that feels tight, thick, or shiny, especially on the hands or face, along with joint pain and stiffness. Muscle weakness, fatigue, and difficulty swallowing can also be signs worth checking. Raynaud's phenomenon, where fingers or toes turn white or blue in cold temperatures, is another common symptom linked to this condition.
What does a positive PM/Scl-100 antibody result mean?
A positive result means your immune system has produced antibodies associated with systemic sclerosis or an overlap between scleroderma and myositis. This doesn't confirm a diagnosis on its own, but it's an important piece of the puzzle alongside your symptoms and other testing. If your result is positive, it's a good idea to seek a full evaluation to understand next steps.
What should I do if my results are abnormal?
If your result comes back positive, keep track of your symptoms like skin changes, joint pain, or muscle weakness so you have detailed information for further evaluation. Consider retesting or additional lab work to build a fuller picture over time. Seek medical care promptly if you experience severe symptoms like difficulty breathing or swallowing, or rapidly worsening skin or muscle changes.
How often should I retest?
If your first result is negative but symptoms persist or worsen, retesting every 6-12 months can help catch any changes early. If you've tested positive, tracking your levels periodically alongside symptom changes can help you and any care team monitor how things are progressing. Your healthcare situation and symptom pattern should guide the exact timing.

Negative

What this means

A negative result means no PM/Scl-100 antibodies were detected in your blood, which does not support systemic sclerosis or scleroderma/myositis overlap based on this marker. If symptoms persist, other tests may still be needed to get a full picture.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
