The antihuman globulin (AHG) test was discovered in 1945 by whom?

You are performing an ABO/Rh on a patient as part of a routine Type and Screen procedure. You encounter a discrepancy between the forward and reverse type. Upon examination of the patient’s red cells under the microscope, you observe cells that are arranged like “stacks of coins”. What is this called? How would you work to distinguish between this occurrence and true agglutination? Describe the reagents used and procedural steps.

For an individual whose Phenotype is 0: The possible genotype(s) is(are):_________ The antigen(s) present on the red cell are:  ____________ The antibodies in the plasma/serum are:  ___________

If an individual with a partial D expression is transfused with a normal Rh-positive unit of blood, a likely result will be:

A1 lectin agglutinates:

An immunogenic substance that reacts with an antibody is:

Determine the ABO/Rh from the given reactions.   Anti-A       Anti-B     Anti-D    Rh control       A1 cells     B cells     0               0            3+            0                   3+            3+           

A patient came in for a routine type and screen prior to surgery. The antibody screen was negative at 37°C and at the AHG phase. Check cells did not produce agglutination often. What is a possible explanation for this result?

All of the following conditions may produce a positive DAT except:

We rely more on nonverbal cues when determining ones __________.
