Rh blocking test
Rh blocking test[¦är¦āch ¦bläk·iŋ ‚test] (immunology) A test for the detection of Rh antibody in plasma wherein erythrocytes having the Rh antigen are incubated in the patient's serum so that the antibodies may be adsorbed on these cells, which are then employed in the antiglobulin test. Also known as indirect Coombs test; indirect developing test. Rh blocking test
Rh block·ing testa test for nonagglutinating Rh antibodies: an Rh agglutination test is first carried out; if the test result for Rh agglutinins is negative, then 1 drop of anti-Rho agglutinating serum of moderate titer is mixed with the patient's serum containing Rh-positive test cells; if after incubating for from 1-2 hours at 37°C no agglutination occurs, Rho-blocking antibodies are assumed to be present in the patient's serum. |
