A client diagnosed with hemophagocytic lymphohistiocytosis requires multiple blood transfusions. One of his family members wishes to donate blood. Which of the following conditions would DISQUALIFY someone from donating blood?

  1. current medical condition of hyperthyroidism
  2. new mother, 10 weeks postpartum
  3. currently ill with common cold
  4. past medical history of tuberculosis; completed treatment and recovered 3 years ago
Number 3 is correct.
Someone with current symptoms of a common cold or the flu cannot donate blood. A potential donor must be free of cold or flu symptoms on the day of donation. Those with hyperthyroidism, new mothers, and people who are at least 3 years recovered from tuberculosis after completing treatment are eligible to donate blood.
