A person was advised to do urine tests and a blood tests for glucose. Glucose was detected in his urine. He was not taking any medications. Which of the following values will correspond to the amount of glucose in the blood of a person?

  • Correct answer
    A
    200 mg of glucose per 100 ml of blood
  • B
    140 mg of glucose per 100 ml of blood
  • C
    120 mg of glucose per 100 ml of blood
  • D
    100 mg of glucose per 100 ml of blood

Solution

The renal threshold of glucose is 160–180 mg per 100 ml of blood. If the blood values of glucose are below this level, the kidneys will absorb all the glucose from the filtrate. If it rises beyond this value, glucose appears in urine.

Hence, the correct answer is option: 'A'.
