Not quite. Different blood types result from different antigens present on the membranes of red blood cells.
True
Yes, it is possible to have antibodies for herpes without actually having the virus. Antibodies can be present in the body as a result of previous exposure to the virus or through vaccination.
A non-reactive RVS test means that the individual tested does not have detectable antibodies for HIV, indicating a negative result. It suggests that there is no current HIV infection present.
Your body creates antibodies - as a result of being infected. An antibody only attacks an infection it's been 'programmed' to identify - so a single antibody will not attack multiple diseases. For example - say a person develops measles and chicken pox. Their immune system would produce two different antibodies to attack each disease.
what is the result when hiv is non reactive
Producing antibodies in response to a vaccination
A positive result means that antimyocardial antibodies are present and that heart disease or damage is likely. Further testing may be needed as other autoantibodies could also be present, causing a false abnormal test.
Anti-sera AB appears pink in color due to the presence of specific antibodies that interact with antigens in a test medium, often involving a dye or chromogen that produces a visible color change. This pink color can also result from the aggregation of immune complexes formed during the reaction between antibodies and their corresponding antigens. The intensity of the pink hue may vary based on the concentration of antibodies and antigens present.
The test you are referring to is called the slide agglutination test. In this test, samples of an unknown bacterium are mixed with different types of antibodies (antisera) and observed under a microscope. If the antibodies react with the bacteria, clumps or aggregates will form, indicating a positive result.
A hypothesis could be: "If different color pigments are present in the flower petals, then crossbreeding two different colored flowers will result in a flower with both colors present."
Latex agglutination test is a diagnostic method that uses latex beads coated with antibodies to detect antigens or antibodies in a sample. When the target substance is present, it binds to the latex particles, causing them to clump together or agglutinate, which can be visualized and interpreted as a positive result. It is commonly used in clinical laboratories for rapid and sensitive detection of various infections and autoimmune diseases.
Antibodies bind the antigen, which then targets the antigen for elimination by innate mechanisms
