“There's usually no single test to diagnose autoimmune disease. You have to have certain symptoms combined with specific blood markers and in some cases, even a tissue biopsy. It's not just one factor.” Diagnosis can also be difficult because these symptoms can come from other common conditions.
Autoimmune tests may include anti-dsDNA, anti-RNP, anti-Smith (or anti-Sm), anti-Sjogren's SSA and SSB, anti-scleroderma or anti-Scl-70, anti-Jo-1, and anti-CCP. Antibody against cardiolipin also may be tested. If you have several of these antibodies—or have them in high amounts—you may have an autoimmune disease.
A negative ANA test means that no antinuclear antibodies were detected; however, it is still possible for someone with a negative test result to have an autoimmune disease. If the patient's symptoms continue to linger, they may require additional autoimmune testing.

These include the complete blood count (CBC), urine analysis (UA), sedimentation rate (ESR), C-reactive protein (CRP), comprehensive metabolic panel (CMP), and muscle enzymes. In the CBC, we are looking for an anemia of inflammatory disease which can develop.
Blood tests which detect inflammation are not sensitive enough to diagnose serious underlying conditions, generating an 85% false positive rate and a 50% false negative rate when used for this purpose, according to new research.
Living with Symptoms, but No Diagnosis
Autoimmune diseases are often difficult to diagnose, with no one test available to determine autoimmunity. Tests like the antinuclear antibody test (ANA) or others that look for autoantibodies can indicate an autoimmune disease but may not confirm a diagnosis.
Autoimmune diseases can affect many types of tissues and nearly any organ in your body. They may cause a variety of symptoms including pain, tiredness (fatigue), rashes, nausea, headaches, dizziness and more. Specific symptoms depend on the exact disease.
In fact, if an autoimmune disorder is left untreated, it can lead to more serious complications and even death. The person will also run a higher risk of infections.
When the body senses danger from a virus or infection, the immune system kicks into gear and attacks it. This is called an immune response. Sometimes, healthy cells and tissues are caught up in this response, resulting in autoimmune disease.
Based on visual observation, the ancients characterised inflammation by five cardinal signs, namely redness (rubor), swelling (tumour), heat (calor; only applicable to the body' extremities), pain (dolor) and loss of function (functio laesa).
You have aches and pains
Experiencing pain regularly that is not attributable to an injury is an indicator of a lot of inflammation. If you notice pain at the end of your range of motion, you could have too much inflammation. It could also be a signal that you have developed arthritis.
Some of the most common signs of chronic inflammation include: Body discomfort, including joint stiffness, tendonitis and muscle pain. Sleep disorders like insomnia, sleep apnea and persistent fatigue. Weight gain or unexplained weight loss.
Your healthcare provider may order an ANA test if you have signs of an autoimmune disease such as fever, fatigue, a butterfly rash, muscle pain, and joint pain.
Antinuclear antibodies are markers for a number of autoimmune diseases, the most notable of which is systemic lupus erythematosus (Ferrell and Tan, 1985). Antibodies to specific nuclear constituents are high specific for certain collagen vascular diseases.
Blood tests.
Blood tests can determine if you have typical levels of infection-fighting proteins (immunoglobulins) in your blood and measure the levels of blood cells and immune system cells. Having numbers of certain cells in your blood that are outside of the standard range can indicate an immune system defect.
The most common reasons for chronic inflammation include: Autoimmune disorders, such as lupus, where your body attacks healthy tissue. Exposure to toxins, like pollution or industrial chemicals. Untreated acute inflammation, such as from an infection or injury.
Chronic inflammation can contribute to an overproduction of inflammatory cytokines. As the body gets flooded with these molecules during chronic inflammation, the cytokines actually begin to attack healthy joint and muscle tissue, resulting in pain, swelling, redness, and stiffness.
What are the signs of inflammation? The four cardinal signs of inflammation are redness (Latin rubor), heat (calor), swelling (tumor), and pain (dolor). Redness is caused by the dilation of small blood vessels in the area of injury.
For many autoimmune diseases, symptoms come and go, or can be mild sometimes and severe at others. When symptoms go away for a while, it's called remission. Flares are the sudden and severe onset of symptoms.
No one is sure why autoimmune diseases happen. But you can't catch them from other people. Autoimmune diseases do tend to run in families, which means that certain genes may make some people more likely to develop a problem.
Foods to avoid include grains, legumes, dairy, processed foods, refined sugars, industrial seed oils, eggs, nuts, seeds, nightshade vegetables, gum, alternative sweeteners, emulsifiers, and food thickeners, said Romano.
