Blood typing_ how do you find out to which blood group someone belong?
This is experiment in immunology lab
I want method, results and discussion
Of detect ( A and B) blood

Expert Solution

To determine the blood-type you need anti-A and anti-B antibodies.

method

Make three tubes

Contains mixture of (sample blood + anti-A antibodies)
Contains mixture of (sample blood + anti-B antibodies)
Only sample blood (negative control)

results

if there is agglutination seen in any of the first two or both, it suggests the positive results for respective antigen (A or B)

If a person has blood type A, the agglutination will only be senn in tube A, because only anti-A antibodies can act on antigen A present on RBCs of blood-type A.

If a person has blood type B, the agglutination will only be seen in tube B, because only anti-B antibodies can act on antigen B present on RBCs of blood-type B.

If a person has blood-type AB, the agglutination will be seen in both tubes 1 and 2, because anti-A and anti-B antibodies will act on antigen A and B present on RBCs of blood-type AB.

If a person has blood-type O, the agglutination will not be seen in any of the tubes because RBCs of blood-type O do not contain any of these two antigens.

Activity 4: Experiment (YOU PRETEND TO DO THIS EXPERIMENT) The control group in an experiment is the group who does not receive any treatment and is used as a benchmark against which other test results are measured. A control group is used in an experiment as a point of comparison, so that it can be isolated in testing that the experiment did, or did not, have the intended effect. For example, scientists have developed many tests using reagents (substances used...

Suppose that someone gives you an unknown solution, and you wish to find out whether this solution contains glucose. To do this, you perform a Benedict’s test. Performing this test requires adding something called ____________________ solution to the solution of interest. Consider the solution you named in the previous question. After adding this to your solution of interest, what do you have to do next? If you perform a Benedict’s test on a solution that does contain glucose, then it...
