You had blood test it showed you have antibodies in your blood?
blood test for antibodies ANA TEST Antibodies are often a sign of an infection best thing to do is talk to your doctor
What are the effects of the ana blood test?
There is no actually effect of the ana blood test. An ana blood test is to check for a type of antibodies that work against your body instead of helping your body.
What is the medical problem ANA?
There is a test for ANA, meaning anti-nuclear antibodies. This is used to detect immune system disorders. ANA is not, itself, a medical problem. As with any medical test, the results can be in error (false positive or false negative) and should be interpreted in the context of other tests and the clinical presentation.
What does a negative 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. This is not normal. 10 million Americans have a positive ANA. 1.5 million have lupus. 2-3 percent of people with lupus will have a negative ANA. The pattern that shows up under when the cells are treated with immunofluorescent dye is more important than the fact that the test is postive. Lupus will cause a speckeld pattern. The ANA test is a titer. This means the number is how many times a sample of blood had to be diluted to come up with a sample that has no antinuclear antibodies in it. Typically the numbers will be 40, 80, 160, 320, 640 etc. Many people have a positive ANA and don't have any active disease. The older a person gets, the more likely they are to test postive.
What is a normal ANA?
A normal ANA (anti-nuclear antibody) test result is usually negative, indicating that there are no detectable antibodies to the cell nucleus. However, it is important to interpret ANA results in conjunction with clinical symptoms and other diagnostic tests to determine their significance.
What is a hematology lab test ANA for?
ANA or Antinuclear Antibody is a test that helps detect autoimmune disorders in the body. This is usually done to diagnose systemic lupus erythematosus or SLE.
ANA is a?
ANA is an acronym standing for: AntiNuclear Antibodies.
Does it mean you have an auto immune disease if you have had a positive ana test?
A positive ANA test does not necessarily mean the patient has an autoimmune disease. An ANA test is not specific for autoimmunity, but is a sign of inflammation that is often specific to autoimmunity. Specific antibodies are usually tested for to determine if a patient has an autoimmune disease.
Meaning of ANA?
ANA stands for (number of) Antinuclear Antibodies.

Is high ANA titer an indication of disease progression in rheumatoid arthritis?
The acronym ANA stands for anti-nuclear antibody. When your doctor suspects you may have an autoimmune disorder, he or she will test for the presence of anti-nuclear antibodies in your blood. To perform the ANA test, serum from your blood specimen is added to microscope slides which have commercially prepared cells on the slide surface. If your serum contains antinuclear antibodies (ANA), they bind to the cells (specifically the nuclei of the cells) on the slide. A second antibody, commercially tagged with a fluorescent dye, is added to the mix of patient's serum and commercially prepared cells on the slide. The second (fluorescent) antibody attaches to the serum antibodies and cells which have bound together. When viewed under an ultraviolet microscope, antinuclear antibodies appear as fluorescent cells. If fluorescent cells are observed, the ANA test is considered positive. If fluorescent cells are not observed, the ANA test is considered negative. The ANA titer is determined by repeating the positive test with serial dilutions until the test yields a negative result. The last dilution which yields a positive result (flourescence) is the titer which gets reported. For example, if a titer performed for a positive ANA test is: 1:10 positive 1:20 positive 1:40 positive 1:80 positive 1:160 positive 1:320 negative The reported titer would be 1:160. Generally, an ANA titre of 1:80 or higher is considered positive. At least 5% of the population has a positive ANA titre with no disease activity. For those with disease activity, the ANA titre does not indicate the absolute amount of disease activity (e.g. one person with an ANA titre of 1:640 may have very little disease activity, while another with a titre of 1:320 may have significant disease activity). The ANA titre must be evaluated in the context of the individual. The ANA test by itself is not specific for any disease. Your clinical presentation, as well as tests for additional antibodies, complements and factors in your blood will also be used to determine what condition, if any, is present, and how to treat it.

Does lupus always show in ANA test?
No. 3 to 5% of patients will be negative.
