There are ELISA tests to detect various kind of diseases, such as dengue, malaria, Chagas disease, [30] Johne's disease, and others. [31] ELISA tests also are extensively employed for in vitro diagnostics in medical laboratories. The other uses of ELISA include: detection of SARS-CoV-2 antibodies in blood samples [32]
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
An antibody titer is a measurement of how much antibody an organism has produced that recognizes a particular epitope. It is conventionally expressed as the inverse of the greatest dilution level that still gives a positive result on some test. ELISA is a common means of determining antibody titers.
The enzyme-linked immunosorbent assay or ELISA is a diagnostic method for quantitatively or semi-quantitatively determining protein concentrations from blood plasma, serum or cell/tissue extracts in a multi-well plate format (usually 96-wells per plate). Broadly, proteins in solution are absorbed to ELISA plates.
Serological assays are tests that detect specific antibodies and are used to determine whether those antibodies are in an organism's blood; such tests require a significant concentration of unbound antibody in the blood serum. Serostatus is a term denoting the presence or absence of particular antibodies in an individual's blood. An individual ...
In immunology the particular macromolecule bound by an antibody is referred to as an antigen and the area on an antigen to which the antibody binds is called an epitope. In some cases, an immunoassay may use an antigen to detect for the presence of antibodies, which recognize that antigen, in a solution.
A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick. Multiple tests for specific blood components, such as a glucose test or a cholesterol test , are often grouped together into one test panel called a blood panel or blood work .
An antibody elution removes bound antibody from the surface of a red blood cell to aid in the antibody identification process. An antibody elution is a clinical laboratory diagnostic procedure which removes sensitized antibodies from red blood cells , in order to determine the blood group system antigen the antibody targets.
