Question

Which of the following is NOT a limitation of the antibody screening test?

1) Antigens with frequencies of less than 10 percent are not usually represented on screening cells
2) They may yield negative results when the titer of an antibody drops below detectable limits
3) You can have a false negative if the patient is in the window period
4) With proper performance and interpretation, they minimize the risk of a delayed hemolytic transfusion reaction

Answer 1

Option 4 is NOT a limitation of the antibody screening test. The antibody screening test has limitations in identifying certain antigens and may yield false negatives in certain situations.

Step-by-step explanation:

The correct answer is 4) With proper performance and interpretation, they minimize the risk of a delayed hemolytic transfusion reaction. This statement is NOT a limitation of the antibody screening test.

The antibody screening test is used to detect antibodies in a patient's serum, but it does have limitations. The other statements listed in options 1, 2, and 3 are limitations of the antibody screening test.
