What does a biochemistry test show?
Non-clotting blood must be obtained for some clinical-biochemical examinations. Blood is collected in containers with the addition of anticoagulant (anti-clotting) agents. Plasma is obtained by centrifuging non-clotting blood. Blood can be centrifuged immediately after collection, which saves time in acute conditions..

What is the purpose of a biochemical test?
Biochemical tests are used to identify bacterial species by differentiating them on the basis of biochemical activities. The difference in protein and fat metabolism, carbohydrate metabolism, enzyme production, compound utilization ability, etc. are some factors that aid in bacterial identification.Oct 16, 2018.
Catalase Test
The catalase test is a biochemical test used to detect the presence of the enzyme catalase in bacteria. The test involves adding hydrogen peroxide to a colony of bacteria on a culture plate and observing for the production of bubbles of oxygen gas, indicating a positive result. The test is commonly used to differentiate between different types of b.
Coagulase Test
The coagulase test is a biochemical test used to distinguish between different species of Staphylococcus bacteria. The test involves adding a small amount of plasma to a colony of bacteria on a culture plate and observing for the formation of clots, indicating a positive result. Staphylococcus aureus is coagulase-positive, while other Staphylococcu.
Indole Test
The indole test is a biochemical test used to detect the ability of bacteria to produce the enzyme tryptophanase. The test involves adding Kovac’s reagent to a bacterial culture and observing for a color change, indicating a positive result. The test is commonly used to differentiate between different species of Enterobacteriaceae, which can be eit.
Motility Test
The motility test is a biochemical test used to determine the motility of bacteria. The test involves inoculating a tube containing a semi-solid agar medium with a bacterial culture and observing for the movement of the bacteria through the medium, indicating a positive result. The test is commonly used to differentiate between different species of.
Nitrate Reduction Test
The nitrate reduction test is a biochemical test used to detect the presence of the enzyme nitrate reductase in bacteria. The test involves adding a reagent to a bacterial culture and observing for a color change or the presence of gas, indicating a positive result. The test is commonly used to differentiate between different species of bacteria, p.
Oxidase Test
The oxidase test is a biochemical test used to detect the presence of cytochrome c oxidase in bacteria. The test involves adding a reagent containing the oxidase substrate to a colony of bacteria on a culture plate and observing for a color change, indicating a positive result. The test is commonly used to differentiate between different types of G.
Phenylalanine Deaminase Test
The phenylalanine deaminase test is a biochemical test used to detect the presence of the enzyme phenylalanine deaminase in bacteria. The test involves adding a bacterial culture to a medium containing phenylalanine and observing for a color change, indicating a positive result. The test is commonly used to differentiate between different species o.
Triple Sugar Iron (TSI) Test
The Triple Sugar Iron (TSI) test is a biochemical test used to differentiate between different species of bacteria, particularly Enterobacteriaceae. The test involves inoculating a tube containing a semi-solid medium with a bacterial culture and observing for the production of gas, acid, and hydrogen sulfide. The test results can be interpreted bas.
Urease Test
The urease test is a biochemical test used to detect the presence of the enzyme urease in bacteria.

What is biochemical examination
Oxygen needed to remove organics from water
Biochemical oxygen demand is an analytical parameter representing the amount of dissolved oxygen (DO) consumed by aerobic bacteria growing on the organic material present in a water sample at a specific temperature over a specific time period. The BOD value is most commonly expressed in milligrams of oxygen consumed per liter of sample during 5 days of incubation at 20 °C and is often used as a surrogate of the degree of organic water pollution.
