Tests for infectious diseases
Lateral flow immunoassay - immunoassay based on the principle of thin layer chromatography and included reaction between antigen and relevant antibody in the biological materials (urine, whole blood, serum or plasma, saliva, feces, etc.).
This type of assay is carried out using test strips, panels or test cassettes, which ensure the speed of testing. LFIA is rapid test.
Being an effective diagnostic tool, rapid tests allow you to visually determine and evaluate the content of antigens, antibodies, hormones and other diagnostically important substances in the human body within a few minutes. Rapid tests are characterized by a high degree of sensitivity and accuracy detecting more than 100 types of diseases, including such common diseases as tuberculosis, syphilis, gonorrhea, chlamydia infection, various types of viral hepatitis, etc., as well as the entire range of narcotic drugs used with a high reliability of determination. An important advantage of this type of tests is their use in vitro diagnostics which does not require the direct presence of the examined patient.

Enzyme immunoassay (EIA) - method for detection antigens and antibodies based on the determination of antigen-antibody complex due to introduction of enzyme label in one of reaction components with its further detection using relevant substrate changing its color. The basis for any variant of EIA is the determination of enzyme reaction products in study of testing samples compared to negative and positive controls.
To determine antigens and antibodies, a solid-phase (heterogeneous) variant of the enzyme immunoassay is used The use of a solid phase allowed simplification of the process of separating the reaction components by immobilizing one of the components on the solid phase and removing the substances not participating in the reaction.
Enzyme immunoassay has the following advantages over other methods for detecting antigens and antibodies:
- high sensitivity, allowing to detect concentrations up to 0.05 ng/ml;
- the ability to use the minimum volume of the test material;
- storage stability of all ingredients required for EIA;
- the simplicity of the reaction;
- the presence of both instrumental (qualitative and quantitative) and visual accounting;
- the ability to automate all stages of the reaction;
- relatively low cost of diagnostic kits.
