• C. Total blood volume - 5-6 ml
• D. ESR in Wintrobe method - 9-15 mm in males and 20-34 mm in females

Answer 1

The correct option is B Blood sugar (fasting) - 70-100 mg/100 ml

Normal human adult blood should contain between 6 to 20 mg of urea nitrogen per 100 ml (6–20 mg/dl) of blood.

The most commonly used screening tests are determination of the fasting blood glucose level and the blood glucose level tested two hours after a meal. The normal fasting blood sugar content is 70-110 mg per 100 ml of blood.

A typical adult has a blood volume of approximately 5 liters, with females generally having less blood volume than males. Blood volume is regulated by the kidneys.

Results from your ESR rate test will be reported in the distance in millimeters (mm) red blood cells have descended in one hour (hr). The normal range is 0-22 mm/hr for men and 0-29 mm/hr for women.
