The Decision to Donate is Made. The donor needs to be evaluated. What of the following is done to evaluate the donor? (Select all that apply)

Brief Introduction: Organ donor evaluation is a systematic clinical process ensuring immunologic compatibility, infection screening, organ viability, and recipient safety. It involves laboratory testing, serologic profiling, and comprehensive history assessment to minimize graft rejection and disease transmission risks. Rationale: A. ABO blood typing, routine laboratory investigations, and microbiological cultures are essential baseline assessments. ABO compatibility prevents hyperacute rejection, while labs evaluate organ function and metabolic stability. Cultures detect occult infections that could be transmitted to recipients, ensuring transplant safety. B. A thorough physical assessment including height and weight determines organ size matching and physiologic suitability. Anthropometric data ensures appropriate donor-recipient compatibility, particularly in thoracic and abdominal organ transplantation, reducing postoperative complications related to size mismatch and functional insufficiency. C. Screening for risk factors of bloodborne infections such as HIV, hepatitis B, and hepatitis C is mandatory. Serologic screening identifies transmissible pathogens. Although some infections are not absolute contraindications, risk stratification guides recipient selection and post-transplant prophylactic management strategies. D. A detailed medical and social history evaluates conditions affecting organ quality. Comorbidity assessment identifies diseases such as diabetes, hypertension, or malignancy. Social history reveals substance use or high-risk behaviors, which may compromise organ function or increase transmissible disease risk. E. Although this statement includes correct components, the presence of multiple individually correct selections makes “all of the above” redundant in a select-all-that-apply format. Each appropriate evaluation must be independently identified rather than grouped. F. Human leukocyte antigen matching assesses immunologic compatibility. HLA typing reduces the likelihood of graft rejection by identifying donor-recipient antigen similarity. It is particularly critical in kidney and bone marrow transplantation to improve long-term graft survival outcomes. G. Screening for transmissible diseases is essential to prevent donor-derived infections. Infectious screening includes viral, bacterial, and sometimes parasitic pathogens. Identifying these conditions ensures appropriate recipient counseling, prophylaxis, and reduces post-transplant morbidity and mortality.
