They are kits used for diagnostic purposes in the analysis of body fluids such as blood, urine, or cerebro-spinal fluid in clinical biochemistry and hematology laboratories. Consequently, the diagnostic kits help to determine the levels of analytes that are significant in diagnoses for instance enzymes, metabolites, or electrolytes to identify important industrial microorganisms or to diagnose infectious diseases. In addition, they provide crucial data with regard to the specification of diagnosis and monitoring of the treatment process.
The diagnostic kits are ready to use and can be used in all forms of automatic analyzers as well as laboratory procedures. Observations are done on microorganisms that are subjected to a set of conditions and their reactions monitored in terms of change in color or evolution of gas.
- To identify gram-positive bacteria
- To identify gram-negative bacteria
- On Mannitol sugar agar
- In testing gram-negative enteric bacteria in glucose broth with Durham tubes
- In testing the ability of organisms to produce hemolysins in blood agar plates
- To identify the members of the genus Enterococcus
- To differentiate members of Enterobacteriaceae
Biochemical kits play an essential role when conducting tests to identify bacteria species based on their biochemical activities. This is for the reason that bacterial physiology differs from one species to another due to carbohydrate metabolism, protein metabolism, fat metabolism, or enzyme production. Identification of bacterial structural differences is not possible with a naked eye, as a result, the use of biochemical kits is viable in the identification of these structures and in differentiating species.
