ANCA/MPO/PR3 Antibodies Negative ANCA tests results mean it is unlikely that a person's symptoms are due to an autoimmune vasculitis. For a positive result on the indirect immunofluorescence microscopy method, several different ANCA patterns may be seen: 1  Perinuclear (pANCA) – most of the fluorescence occurs near the nucleus. Most often, ANCA tests are performed using indirect immunofluorescence microscopy (IFA). 2  Serum samples are mixed with neutrophils to allow autoantibodies that may be present to react with the cells. 3  The sample is put on a slide and treated with a fluorescent stain.

What Do Your Pap Smear Results Mean? If abnormal or unusual cells were discovered during your Pap smear, you're said to have a positive result. A positive result doesn't mean you have cervical cancer. What a positive result means depends on the type of cells discovered in your test. Here are some terms your doctor might use and what your next course of action might be: Atypical squamous cells of undetermined significance (ASCUS).

- Your test is positive if it finds antinuclear antibodies in your blood. A negative result means it found no ANAs. A positive result may mean that you have an autoimmune disease such as lupus. That’s a disease that damages joints, skin, and other organs. About 95% of people with lupus will test positive for antinuclear antibodies. A positive test result can also mean that you have one of these other autoimmune diseases: Sjögren's syndrome-- a disease that causes joint damage, as well as dry eyes and mouth

Blood tests: Understanding the different kinds A positive result on a screening test does not confirm that the person has HIV infection. More tests are needed to confirm HIV infection. A negative test result does not rule out HIV infection. There is a period of time, called the window period, between HIV infection and the appearance of anti-HIV antibodies.

- A positive DAT means that there are antibodies attached to the RBCs. In general, the stronger the DAT reaction (the more positive the test), the greater the amount of antibody bound to the RBCs, but this does not always equate to the severity of symptoms, especially if the RBCs have already been destroyed.

What does it mean for a baby to be Coombs positive? Best Answer: An indirect Coombs' test determines whether there are antibodies to the Rh factor in the mother’s blood. A normal (negative) result means that the mother has not developed antibodies against the fetus's blood. A negative Coombs' test indicates that the fetus is not presently in danger from problems relating to Rh incompatibility. An abnormal (positive) result means that the mother has developed antibodies to the fetal red blood cells and is sensitized.

- A positive test for ANA does not mean you have an autoimmune disease. The test finds small amounts of these antibodies in up to 15% of healthy people. Antinuclear antibodies are measured in titers.A titer above 1:160 is a positive test result. A positive result may mean: You have systemic lupus erythematosis, or SLE.About 95% of people with this autoimmune disease test positive for antinuclear antibodies. You have another type of autoimmune disease. positive test for ANA does not mean you have an autoimmune disease. The test finds small amounts of these antibodies in up to 15% of healthy people. Antinuclear antibodies are measured in titers.

Rh incompatibility If the mother is Rh-negative, her immune system treats Rh-positive fetal cells as if they were a foreign substance. The mother's body makes antibodies against the fetal blood cells. These antibodies may cross back through the placenta into the developing baby. They destroy the baby's circulating red blood cells. When red blood cells are broken down, they make bilirubin. This causes an infant to become yellow (jaundiced).

RPR Blood Test: A Patient's Guide Normal Results A negative result means that the test is normal. However, a negative result does not always mean a patient does not have syphilis because antibodies are not always produced by the body in response to the syphilis bacteria. Because of this, the RPR is not always accurate.

Antibody Screening It is also used in antenatal screening to detect the presence of antibodies in a pregnant woman's serum that could result in hemolytic disease of the fetus and newborn. Antibody screening may be performed in advance of a crossmatch to permit early recognition and identification of clinically significant antibodies and thereby permit selection of the appropriate crossmatch procedure and RBC units.

- A positive p24 test means that someone is HIV-positive. However, a negative p24 test can mean three things: 1  the person is HIV-negative. 2  the person is HIV-positive but that the test could not detect the p24 protein because the person was infected more than four to six weeks earlier. 3  the levels of p24 antigen are too low to be detectable with current technologies.

Antinuclear Antibodies (ANA) A positive ANA test means autoantibodies are present. By itself, a positive ANA test does not indicate the presence of an autoimmune disease or the need for therapy. Some medications cause a positive ANA. Tell your doctor all prescription, over-the-counter, and street drugs you take. ANA testing can produce a positive result without any actual disease process.

Coagulation Factors One or more coagulation factor activity tests may be ordered to evaluate the function of specific factors. If a test result shows reduced activity, then an antigen test may be ordered as a follow-up test.This is occasionally done to determine if the low activity is due to a decreased quantity of a normal coagulation factor or due to a coagulation factor that does not function normally.Coagulation factor testing may sometimes be ordered if a person has a family history of bleeding.ormal coagulation factor activity usually means normal clotting function. Low activity of one or more coagulation factors usually means impaired clotting ability. Each coagulation factor must be present in sufficient quantity in order for normal clotting to occur, but the level required is different for each factor.
