Which of the following techniques/reagents may be useful in increasing the reactivity of anti-M?

_________ is an antigen in the high-prevalence series (901) that is found in saliva and urine. The corresponding antibody typically reacts at the AHG phase and produces a characteristic refractile, mixed-field reaction.

Cells that have antibody attached to them but are still separated from one another are:

When red blood cells are placed in a solution of 2M urea, the red blood cells will lyse. However, it has been shown that which red blood cells are resistant to lysis?

A 2-unit crossmatch was ordered on a patient in the emergency room. The patient’s antibody screen was negative. One unit was compatible and the other was incompatible at AHG. If the patient’s antibody screen was negative and the donor had no history of antibodies, what could be the reason for this reaction?

Serologic tests determine a person’s:

Which of the following substances may interfere with gel technology but not SPRCA technology?

Units that were positive for P² antigen had to be crossmatched with serum of a patient containing the corresponding antibody because of a short supply of blood. Which of the following crossmatch results would be considered acceptable for transfusion?
