Question 141

Monoclonal antibodies are usually produced by:
  • Question 142

    The results demonstrate compliance with diet and medication. A HbA1C result that is <7.0% indicates glycemic control for most adults with diabetes.
    Chemistry
    A HbA1C result for a diabetic patient is 6.0%. What conclusion can be made regarding this patient's carbohydrate management?
  • Question 143

    The National Heart, Lung, and Blood Institute initiated the National Cholesterol Education Program (NCEP) in 1985. The goal was to reduce the number of Americans with elevated cholesterol and thus reduce illnesses and deaths in the United States due to coronary heart disease. Three adult treatment panels have been published since then with clinical practice guidelines for managing cholesterol levels in adults.
    The most recent panel, Adult Treatment Panel III (ATP III), was published in 2001 and updated in 2004. The NCEP: ATP III also includes criteria for the diagnosis of metabolic syndrome.
    Select the set of laboratory assays that are utilized in the NCEP: ATP III criteria for metabolic syndrome diagnosis.
  • Question 144

    What is the CORRECT blood-to-anticoagulant ratio for coagulations tests?
  • Question 145

    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?
