A 26-year-old female participated in a blood drive. She had no history of donations or deferrals. Evaluation of the donor’s responses to the donor history questions revealed no cause for deferral. Physical Examination: Weight 145 lbs. Temperature 98.8 F Blood Pressure 120/68 mm Hg Pulse 70 beats/min Hemoglobin Satisfactory (screened by Cu2SO4) Disease Testing: HbsAg Anti-HIV Anti-HBc ALT Anti-HTLV-1 Anti-HCV NR R NR NE NR NR Question 1. Can the blood components be labeled and released for issue? Explain. 2. Should this donor be permanently deferred?

1. Joey is participating in a study abroad program and received the following vaccinations 30 days ago: varicella, typhoid (oral), hepatitis B, and polio (oral). May Joey donate at this time. If Joey is deferred, state the reason. 2. Kim comes to the donation site and her physical examination reveals the following data: • Hemoglobin: 13.0 g/dL • Weight: 121 lb • Blood pressure: 150/92 • Pulse: 87 beats/minute • Immunization: Hepatitis B vaccination booster 2 months ago • Medications: Prescription immunotherapy injection 1 week ago for severe seasonal allergies May Kim donate at this time. If Kim is deferred, state the reason. 3. Annika recently made a full recovery after infection with the Zika Virus. She stated her symptoms resolved one month ago. May Annika donate at this time? If Annika is deferred, state the reason. 9. A donor experiences an episode of syncope while donating a unit of blood. How should the blood donor center personnel treat the donor’s condition? When is the donor eligible for future donations? 10. Helen comes to the donation center to donate a unit of blood to be re-infused during a hip replacement in two weeks. Her hemoglobin value is 12.0 g/dL. a. May Helen provide this unit of blood for her upcoming surgery? b. If she does not use the unit of blood, may it be converted to allogeneic use? If not, why? c. What tests must be performed on Helen’s unit of blood for autologous use?

A 45-year-old man was admitted to the hospital with complaints of extreme fatigue and back pain. The patient was diagnosed with hypertension 8 months ago and was prescribed methyldopa. The patient has never been transfused. Admission testing results are as follows: Hemoglobin: 7.5 g/dL Hematocrit: 22% Total bilirubin: 6.8 mg/dL The attending physician ordered four units of packed red blood cells for transfusion as soon as possible. Records indicate that 3 years ago the patient was transfused with four units of red blood cells following an automobile accident. No serological problems were noted at that time. 5. R's DAT result is interpreted as follows: A. Positive B. Negative C. Positive IgG only D. Positive IgG and C3d E. Positive C3d only 6. Given the patient history and serology results, the next test you would perform would be a(n): A. Elution B. Antibody identification panel C. Autoadsorption D. Warm saline wash technique 7. Which of the following describes the mechanism by which the autoantibody was produced in this case? A. Drug adsorption B. Immune complex C. Membrane modification D. Drug-induced autoimmune hemolytic anemia
