Different Diagnostic Tests Using Serum Antibodies

Describe in detail how a technician performs each of the following diagnostic tests with a sample of blood serum that contains fragmentizeicular antibodies, and bespeak the advantages and disadvantages associated with each test . (1) the balance regression toward the mean test, (2) the fluorescent fixture antibody test, (3) the radioimmunoassay, and the enzyme-linked immunosorbent assay. The co-occurrence fixation test is used to detect antibodies for several(prenominal) types of viruses, fungi, and bacterium involves a two step process.. The first part or test system utilizes the perseverings serum, a grooming of antigen from the suspected pathogen, and accompaniment from guinea go throughs. The south part, the indicator system, uses sheep blushful strain cells and prepa ruby antibodies that recognize the sheep violent blood cells. The soft touch step involves heating the patients serum to undo any existing complement in the serum. The antigen and guin ea pig complement are thus added to the serum, and so incubated at 37 degrees Celsius for 90 minutes. An antibody-antigen interaction occurs if there are antibodies specific for the antigen present. The complement is located, or used up, plainly there is no sign signifying that a reaction has taken drive. aft(prenominal) the indicator is added the supply is reincubated.

If the complement was already fixed then the lysis of sheep red blood cells would not take place and the cells would remain entire. After the sample is centrifuged, a clear facile with blood cells at the arsehole is observed. It can be cogitate that the patients serum contained a! ntibodies. If the complement was not fixed, then the sheep cells will be forthcoming to react and they will lyse. After the sample is centrifuged, a red fluid with no intact blood cells at the render is observed and it can be concluded that the serum lacked antibodies. 1 advantage of the complement fixation test is that it can be used to detect a variety of antibodies by change the antigen. Tests can be conducted for diseases such as encephalitis,...If you want to demoralise a full essay, ensnare it on our website: BestEssayCheap.com
