ASCP-MLT Exam Dumps : MEDICAL LABORATORY TECHNICIAN - MLT(ASCP)

Platelet neutralization tests are one of the confirmatory tests that can be used to determine if a patient has a circulating lupus antibody, or lupus anticoagulant. The principle in this test involved the use of a freeze-thawed platelet suspension that, when mixed with the patient plasma, will neutralize the anti-phospholipid antibodies (lupus anticoagulant) present and allow for a corrected aPTT result upon re-testing.

A patient has a history of repeated spontaneous abortion. Coagulation studies reveal an elevated APTT, normal PT, normal platelet function, and normal clotting time. Schistocytes were seen on the peripheral blood smear.

Which test should be performed to determine if the patient has lupus anticoagulant?

Which of the following genotypes cause beta thalassemia minor?

Since cimetidine inhibits CYP2D6, less amphetamine will probably need to be given since it will not be able to be metabolized as readily.

Most drug interactions are like this: one drug inhibits or competes with the same CYP450 as another drug. The end result is that higher concentrations of one, or both, drugs are present, leading to potential toxicity.

A patient is taking cimetidine for a stomach ulcer. This drug inhibits CYP2D6. The patient is now prescribed amphetamine for narcolepsy. Amphetamine is metabolized by CYP2D6. What would you predict?
