Which condition may abnormal coagulation indicate?

• A. Liver disease
• B. Osteoporosis
• C. Hypothyroidism
• D. Asthma

Answer: (A)

Abnormal coagulation is most closely tied to impaired liver function because the liver is responsible for producing most of the clotting factors needed for blood to clot properly. When the liver is diseased, its ability to synthesize these factors (like factors II, VII, IX, and X) drops, leading to longer clotting times (such as an elevated INR or prolonged PT/aPTT) and a higher risk of bleeding. This makes liver disease the best explanation among the options for abnormal coagulation. Osteoporosis involves bone density, hypothyroidism affects metabolic rate, and asthma is a respiratory condition; none of these directly cause abnormal coagulation test results.
