Which of the following best describes how serum is obtained from a blood sample? Serum is obtained by directly extracting the liquid portion from whole blood before any centrifugation. Serum is obtained by spinning down whole blood with ethylenediaminetetraacetic acid (EDTA), which prevents clotting. Serum is obtained by spinning down whole blood that has been treated with ethylenediaminetetraacetic acid (EDTA), resulting in a liquid at the bottom of the tube. Serum is the liquid that remains after blood has clotted and been centrifuged without anticoagulants. None of the above is correct

Blood Banking: 1- List the steps in order for performing an adsorption: I. Incubate the red cell and serum suspension. II. Remove serum from red cells and wash red cells. III. Add serum to washed red cells. IV. Remove serum and use to test against screen/panel cells. Group of answer choices I, II, III, IV II, I, III, IV IV, I, II, III 2- Why would an antibody be found in the eluate only and not in the serum during the investigation of a transfusion reaction? Group of answer choices The antibody is IgM and will only be found in the eluate. There is not sufficient quantity of the antibody to coat the transfused cells and spill over into the serum. The serological testing techniques are not sensitive enough to detect the antibody in the serum. The antibody can be found in the serum if the non-TSU tech would stop shaking the test tube so hard.

Which of the following errors is NOT considered a preanalytical error? a. During a phlebotomy procedure, the patient is opening and clenching his fist multiple times. b. The blood was not permitted to clot and spun in a centrifuge after 6 minutes of collection. c. The patient was improperly identified leading to a mislabeled blood sample. d. The serum sample was diluted with tap water. e. During phlebotomy, the EDTA tube was collected prior to the red clot tube.
