You tested for the glucose level of your patient. You already know that a FBS of 126 mg/dL or greater is considered as diabetes and 100-125 mg/dL is considered as prediabetes. However, the result of the laboratory showed the glucose levels as mmol/L (Patient’s value: 4 mmol/L). Interpret the result.
Conversion Factor for glucose:
1 mg/dL = 0.0555 mmol/L
a. Prediabetes (100-125 mg/dL)
b. Normal (= 99 mg/dL)
c. Diabetes (>/= 126 mg/dL)
Normal (= 99 mg/dL)
