The test tube for Anti-Nuclear Antibody (ANA) testing is typically a purple-top tube, containing EDTA as an anticoagulant. However, always refer to the specific laboratory requirements or test instructions for accurate information.
A purple or lavender specimen container is typically used for antinuclear antibody (ANA) testing. These colors indicate that the tube contains an additive designed to prevent blood clotting, which is important for accurate testing.
The tube for an anti-DNA test is typically purple on the top and lavender on the bottom, known as a lavender-top tube. This tube contains EDTA, an anticoagulant that helps preserve the blood sample for testing.
The positive color for the iodine test is a dark blue or black color. This color change indicates the presence of starch in the test substance.
In direct ELISA, the primary antibody is directly linked to an enzyme for detection, while in indirect ELISA, a secondary antibody linked to an enzyme is used to detect the primary antibody bound to the antigen. Direct ELISA is quicker and more straightforward, but indirect ELISA allows for signal amplification and detection of multiple antibodies bound to the antigen.
A clear or transparent test tube is typically used for a lipid test to easily observe any color changes or reactions that occur during the test.

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.
There are over 100 autoantibodies that can be found in lupus patients. Not all lupus patients have the same autoantibodies. The most common tests are antinuclear antibody with immunofluorescence (ANA), anti double stranded DNA, anti Snith, anti Ro, anti La, and anti SSA.
fluorescent antinuclear antibody test, a test for antinuclear antibody components; used, in particular, for the diagnosis of collagen-vascular diseases.
The antinuclear antibody test of blood is usually negative in Raynaud's disease
Laboratory tests. the fluorescent antibody test uses fluorescent tags that are attached to antibodies for easy detection.
An example of a antibody-based test that can be bought at your local pharamacy wouldbe a Pregnancy Test. a pregnancy test is pretty much an ELISA.
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.
A Celiac disease test involves finding out if the small intestine is sensitive to gluten, and such tests include the endomysial antibody (EMA) test and the tissue transglutaminase antibody test.
The test for anti-smooth muscle antibodies (ASMA) is typically performed using a serum sample collected in a gold or red-top tube, which is designed to allow the blood to clot. These tubes contain no additives or have a gel separator that facilitates serum extraction. After centrifugation, the serum is separated for testing. Always confirm with specific laboratory protocols, as practices may vary.
Chickenpox and shingles result from the same virus, and generate the same antibodies. There is no difference between chickenpox antibody and shingles antibody, and there is only one test (varicella virus antibody) for both.
Its an agglutination test
