Question

Which one of the following is a matching pair of a certain body feature and its value count in a normal human adult?

• A. Urea - 5-10 mg/100 ml of blood
• B. Blood sugar (fasting) - 70 -100 mg/100 ml
• C. Total blood volume - 3-4 litres
• D. ESR in Wintrobe method - 9-15 mm in males and 20-34 mm in females
• E. None of the above

Answer 1

Answer: (B)

Blood sugar (fasting) - 70 -100 mg/100 ml

Normal human adult blood should contain between 6 to 20 mg of urea per 100 ml of blood. Blood glucose levels are maintained within a constant range of 70-110 mg/100 ml of plasma. An adult has a blood volume of approximately 5 liters. Average values of ESR in healthy men are <15 mm/hr and in healthy females, they are higher <20 mm.

Thus, the correct answer is option B.
