According to AABB standards, which donor may be accepted?

The correct answer is based on the guidelines regarding donor eligibility and the deferment periods for certain medical or health-related conditions. AABB (American Association of Blood Banks) standards state that individuals who have experienced a spontaneous abortion are generally eligible to donate blood after a short deferral period, typically around 6 weeks, as long as there are no subsequent complications. Therefore, a person who had a spontaneous abortion 3 months ago is acceptable for donation if they are in good health.

In contrast, other options present conditions that would disqualify a donor. Traveling to a malaria endemic area typically results in a 12-month deferral period before an individual is eligible to donate. Living with someone who has hepatitis poses a risk, as the donor could potentially be exposed to infectious diseases; therefore, this would typically restrict eligibility. Additionally, receiving a blood transfusion usually results in a deferral of at least 12 months to ensure the safety of the donated blood, as there is a risk of transmitting infectious agents.

Thus, the individual who had a spontaneous abortion 3 months ago meets the criteria for donation according to AABB because they have passed the necessary deferment period and any accompanying health assessments confirm their suitability.
