50 g Glucose Test

Blood Glucose 1 h Post 50 g

Measuring blood glucose levels (glycemia) 1 hour after drinking a solution containing 50 grams of glucose is used to screen for gestational (pregnancy-related) diabetes. This test is recommended among pregnant women between the 24th and 28th weeks of pregnancy or earlier if the risk is high. The test is a version of the glucose tolerance test adapted for pregnant women that has a reduced dose of sugar (50 grams rather than 75 or 100 grams), a shorter testing period (1 hour rather than 2 hours) and is more practical (no need to fast before the test).

A normal result is a glucose level below 7.8 millimoles per litre (mmol/L). For results between 7.8 and 11.0 mmol/L, a traditional 2-hour hyperglycemia test must be performed to determine the diagnosis. A glucose level above 11.1 mmol/L indicates the very likely presence of diabetes.

Hot zone

A hot zone is a section of a facility (sometimes an entire facility or even a city district) where there is a high risk of contamination by patients with an infectious disease. All individuals entering a hot zone must respect appropriate protective measures. By analogy, “cold zone” and “warm zone” are used to refer to areas where there is no infected individual or only individuals suspected of having an infection.
