Often, the first symptoms are fatigue, muscle aches and a low fever. The classic sign of an autoimmune disease is inflammation, which can cause redness, heat, pain and swelling. The diseases may also have flare-ups, when they get worse, and remissions, when symptoms get better or disappear
A negative test means that an active autoimmune disease is unlikely.
A positive ANA test means that you have high levels of ANA in your blood. However, this doesn’t mean that you have an autoimmune disease. Up to 15 percent of completely healthy people have a positive ANA test. This is called a “false-positive” test result.
A positive ANA test alone can’t diagnose a specific disease. However, some conditions that are associated with a positive ANA test include:
systemic lupus erythematosus (lupus): an autoimmune disorder that can affect different parts of your body, including the heart, digestive tract, and skin
chronic liver disease (cirrhosis): scarring of the liver, which is most commonly caused by alcohol abuse and viral infections
rheumatoid arthritis: an autoimmune disorder that causes pain, swelling, and stiffness in the joints
Sjögren syndrome: an autoimmune disorder that affects the salivary and lacrimal glands, which produce saliva and tears
scleroderma: an autoimmune disorder that primarily affects the skin and other connective tissues
thyroid disease: a range of conditions can affect your thyroid, including hypothyroidism and hyperthyroidism
temporal arteritis: a disorder, likely caused by an autoimmune response, in which the arteries supplying blood to the head and brain become damaged
Examples include thyroid supplements, vitamins such as B12, or insulin injections. If the autoimmune disorder affects the blood, you may need blood transfusions. People with autoimmune disorders that affect the bones, joints, or muscles may need help with movement or other functions.
Test Method 1 : The ANA panel is similar to other blood tests. A phlebotomist will tie an elastic band around your upper arm so your veins swell with blood. This makes it easier for them to find a vein. After cleaning the site with an antiseptic, they’ll insert a needle into a vein. You might feel some moderate pain when the needle goes in, but the test itself isn’t painful. Blood is then collected in a tube attached to the needle. Once the blood is collected, the phlebotomist will remove the needle from your vein and cover the puncture site.
In infants or children, a lancet (small scalpel) may be used to puncture the skin, and blood may be collected in a small tube called a pipette. It may also be collected on a test strip.
The blood is then sent to a lab for examination.
Report available : The TAT for this test is around 24 hours.
