What is hepatitis virus tests?
These tests are based primarily on antigen-antibody reactions--an antigen being a protein foreign to the body, and an antibody another type of protein manufactured by lymphocytes (a type of white blood cell) to neutralize the antigen.
What antibodies are tested for by Selectogen I and II?
Selectogen I tests for IgG antibodies to hepatitis A virus, hepatitis B virus core antigen, and hepatitis B surface antigen. Selectogen II tests for IgG antibodies to hepatitis C virus, hepatitis B core antigen, and hepatitis B surface antigen.
What is the purpose of hepatitis virus tests?

What tests can tell if you have strep throat?

Should Brucella abortus antigen and Brucella melitensis antigen both be used to test for brucella?
Because of the cross-reaction of the LPS (Lipo poly Saccharide) of Brucella abortus. B. militensis and B. suis, only one antigen is used for serological diagnosis. Virtually all agglutination tests use the B. abortus antigen. There is no need to test with B. militensis.
What services does Prenetics offer at Hong Kong Airport?

What is the Uses of antigen and antibody reaction?
Antigen-antibody reactions are fundamental to the immune system's ability to identify and neutralize foreign substances. They are used in diagnostic tests (e.g., ELISA) to detect the presence of specific antigens or antibodies in samples such as blood. These reactions also play a crucial role in vaccine development and research on autoimmune diseases.
What is the molecule that can be recognized by the immune system?
Antigens.
What characteristics does a normal hepatitis virus test have?
Reference ranges for the antigen/antibody tests are as follows: hepatitis A antibody, IgM: Negative, hepatitis B core antibody: Negative, hepatitis B e antibody: Negative, hepatitis B e-antigen: Negative.
Why is prostate specific antigen done?
Prostate-specific-antigen tests are done to gauge the amount of prostate-specific antigens in the bloodstream. In healthy young males, the PSA count is low, but the amount of PSA in the bloodstream slowly increases with age as the prostate becomes enlarged.
