Agglutination
particles (such as red blood cells or bacteria or latex beads) suspended in a liquid collect into clumps in response to an antigen or antibody. COOMBS TEST
Cell culture
removal of cells from an animal and their subsequent growth in a favorable artificial environment (in vitro).
Cell culture examples
Primary Cell culture and Secondary Cell cultures (genetic change from primary).
Cell line
population of cells that can be maintained in
culture for an extended period of time, retaining stability of certain phenotypes and functions.
Types of cell lines
Continuous, Transformed, and Cancerous/Immortal
Cerebral Spinal Fluid
Liquid within the ventricles of the brain and the subarachnoid spaces of the cranium and spine.
Diagnostic test controls
Procedures used to ensure that reagents and lab instruments are working within predefined specifications, thereby safeguarding the reliability of test results.
Diagnostic test reagent
Substances used in laboratories to determine specific
types of pathogens, metabolic abnormalities, physiological
anomalies, and genetic diseases.
Fluorochrome
A chemical that fluoresces, especially one used as a label in biological tests and research
Immunodiagnostic tests
based on interaction of antibody and antigen. ELISA and Serum Assays
Molecular diagnostic tests
tests that analyze genome. PCR
Precipitation
precipitation reaction is one in which dissolved substances in solution react to form one (or more) solid products. In immunodiagnostic precipitation tests, it is the
binding of antigen and antibody that form larger and larger Ag-Ab complexes that become large enough to precipitate
out of solution.
Titer
A measure of the amount of a substance (such as an antibody) in a liquid sample that is obtained by subjecting the sample to serial dilutions (as with saline) to determine
the maximum dilution at which the sample retains a specific activity (such as neutralizing an antigen).
Tumor antigens
Abnormal proteins produced by tumor cells that can trigger an adaptive immune response.
