Which type of relative's history is relevant for screening inherited thrombophilia?

• A. 3rd degree relatives
• B. 1st degree relatives
• C. 2nd degree relatives
• D. Distant relatives

Answer: (B)

The relevance of a first-degree relative's history is crucial in the screening of inherited thrombophilia because first-degree relatives share a higher percentage of genetic material compared to more distant relatives. First-degree relatives include parents, siblings, and offspring, and their medical histories provide significant insights into potential hereditary conditions, including thrombophilia. Inherited thrombophilia refers to genetically predisposed conditions that increase the risk of thrombosis, often due to clotting factor deficiencies or abnormalities. When assessing a patient for these conditions, understanding the thrombotic events in first-degree relatives helps to evaluate the familial risk. If a parent or sibling has a known history of venous thromboembolism or other related complications, it underscores a greater likelihood that the patient might also be carrying a genetic predisposition. In contrast, while second-degree relatives like grandparents or aunts/uncles may also have some relevance, they share less genetic material and therefore their history may not be as informative regarding the patient’s risk for inherited conditions. Distant relatives, such as cousins or more remote family members, provide even less genetic insight and typically are not utilized for direct risk assessment in inheritance patterns. Consequently, focusing on first-degree relatives offers the most pertinent information for effective screening and risk evaluation in the
