If fluorescent cells are seen, the test is positive. When positive, the serum is diluted, or titered, and the test done again.
A positive Molisch's test result indicates the presence of carbohydrates.
Biochemical tests commonly used to identify Proteus vulgaris include urease test (positive result), indole test (negative result), motility test (positive result), citrate test (negative result), and carbohydrate fermentation tests (positive results for lactose and sucrose, negative result for glucose). These tests together help in confirming the presence of Proteus vulgaris in a given sample.
Acetaminophen is not expected to give a positive result in Lassaigne's test for nitrogen and sodium due to its lack of nitrogen-containing functional groups. Similarly, it is unlikely to give a positive result in the ferrox paper test, which is typically used for detecting the presence of phenols.
blue/positive
The oxidase test is a nonfermentative test in which the presence of gas bubbles indicates a positive result. Gas bubbles result from the reaction of the test reagent with cytochrome c oxidase, which is present in certain bacteria like Pseudomonas species.
can taking meloxicam yield a positive result on antinuclear antibody (ANA) test
HI
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
The antinuclear antibody test is done by adding a person's serum to commercial cells mounted on a microscope slide. If antinuclear antibodies are in the serum, they bind to the nuclei of cells on the slide.
The question is unclear, however If you go to the related link (Antinuclear Antibody Test ) below you Will find detailed information on the Antinuclear Antibody Test
A positive test in a person with symptoms of an autoimmune or rheumatic disease helps the physician make a diagnosis.
Normal results will be negative, showing no antinuclear antibodies.
ANA positive means that a person's blood test showed the presence of antinuclear antibodies, which can indicate an autoimmune disorder such as lupus or rheumatoid arthritis. Further testing and evaluation by a healthcare provider are usually needed to determine the significance of this result and the underlying cause.
a second antibody is added to the mixture. This antibody is "tagged" with a fluorescent dye so that it can be seen. The second antibody attaches to any antibodies and cells bound together
Yes, it is possible for a positive antinuclear antibody (ANA) test to change to negative. This could happen if the underlying condition that was causing the positive result resolves or goes into remission. However, it is important to consult with a healthcare provider for proper evaluation and interpretation of test results.
ANA is the antinuclear antibody test. It is used to help evaluate a person for autoimmune disorder that may affect many organs and tissues.
