EXERCISE 8. CLINICAL THINKING V:
CROSSMATCH TESTING
To perform a crossmatch test:
Obtain EDTA blood samples from both the donor and the
recipient.
Centrifuge both samples to separate the cells from the
plasma.
Remove the plasma from each sample and placed in a sepa-
Rotate the slide at room temperature for 1 minute.
Examine to look for signs of agglutination or clumping. If
agglutination occurs, the blood is incompatible.
The major drawback to this method is that potentially fatal
hemolytic reactions will be missed.
EXERCISE 9. CLINICAL THINKING CHALLENGE
5. At some point, the instrument will be out of commis-
