What does a positive ana test mean? A positive ANA (anitnuclear antibody) test means that the person makes antibodies against the nucleus of their own cells. All cells live for a while and then die.When they die, they break down in the blood. The antinuclear antibodies think that the debris from the nucleus is a germ that shouldbe destroyed. positive ANA (anitnuclear antibody) test means that the person makes antibodies against the nucleus of their own cells. All cells live for a while and then die.

Understanding the ANA Blood Test (Antinuclear Antibody Test) To perform the ANA blood test, sometimes called FANA (fluorescent antinuclear antibody test), a blood sample is drawn from the patient and sent to the lab for testing. Serum from the blood specimen is added to microscope slides which have commercially prepared cells on the slide surface.

Overview By Mayo Clinic Staff. An ANA test detects antinuclear antibodies (ANA) in your blood. Your immune system normally makes antibodies to help you fight infection. In contrast, antinuclear antibodies often attack your body's own tissues — specifically targeting each cell's nucleus. In most cases, a positive ANA test indicates that your immune system has launched a misdirected attack on your own tissue — in other words, an autoimmune reaction. But some people have positive ANA tests even when they're healthy.

Antinuclear Antibody Test (ANA) The ANA test is performed using a blood sample. An ANA test is performed by testing the blood in the laboratory. The antibodies in the serum of the blood are exposed in the laboratory to cells. It is then determined whether or not antibodies are present that react to various parts of the nucleus of cells. Thus, the term anti-nuclear antibody.

Antinuclear Antibody Panel (ANA Test) However, other tests may still be needed based on your symptoms. Some people with autoimmune diseases may test negative for ANA but positive for other antibodies. A positive ANA test means that you have high levels of ANA in your blood. A positive ANA test is usually reported as both a ratio (called a titer) and a pattern, such as smooth or speckled. Certain diseases are more likely to have certain patterns. The higher the titer the more likely the result is a “true positive” result, meaning you have significant antinuclear antibodies and an autoimmune disease. However, a positive result doesn’t always mean that you have an autoimmune disease.

What is the ANA Blood Test? In this test, lab technicians determine the pattern and concentration of autoantibodies in the blood. The normal titer of antinuclear antibody is 1:40; higher titers of this autoantibody can indicate that a person is affected by an autoimmune diseases. Some of the conditions that can cause a high ANA titer include Lupus, scleroderma, and rheumatoid arthritis (WebMD). slide 2 of 4. Why the Test is Ordered According to the American Association for Clinical Chemistry, the ANA blood test is ordered when someone exhibits the signs and symptoms of an autoimmune disorder.
