    • 160 to 180 mg/dL

    • 130 to 190 mg/dL

    • 140 to 160 mg/dL

    Correct Answer
    A. 160 to 180 mg/dL
    Explanation
    The renal threshold for glucose refers to the blood glucose level at which the kidneys start to excrete glucose into the urine. In a healthy individual, this threshold is typically around 160 to 180 mg/dL. Above this range, glucose spills into the urine as the kidneys are unable to reabsorb all of it. This is an important indicator for diabetes, as elevated levels of glucose in the urine can be a sign of uncontrolled blood sugar levels.
