The International Diabetes Federation (IDF) has recently highlighted the importance of the 1-hour post-load plasma glucose (1-h PG) test as a superior method for identifying individuals at an elevated risk of developing diabetes. This recommendation is aimed at enhancing the early diagnosis and intervention for those with prediabetes, thereby potentially preventing the onset of Type 2 diabetes.
Prediabetes, also known as intermediate hyperglycemia, marks a critical transition stage from normal glucose regulation to Type 2 diabetes, a condition characterized by the body’s inadequate insulin production or resistance to insulin. This stage alters how the body processes blood sugar. The 1-h PG test, according to a statement by the IDF, offers a more sensitive and practical approach for screening individuals at this crucial juncture.
A value of 155 mg/dL or higher in the 1-h PG test signals prediabetes, prompting the recommendation for lifestyle changes and participation in diabetes prevention programs. More alarmingly, a reading of 209 mg/dL or above is indicative of Type 2 diabetes, necessitating further evaluation and treatment.
Despite the clear advantages of the 1-h PG test in detecting diabetes risk at an earlier stage, it remains underutilized in diagnostic practices. With the majority of laboratories focusing on fasting and 2-hour post-glucose load tests, the potential for early intervention based on the 1-h PG results is often missed. This gap in the diagnostic approach underscores the need for wider adoption of the IDF’s latest recommendations.
By incorporating the 1-h PG test into routine screening, healthcare providers can identify prediabetes and diabetes more effectively, offering a critical window for early intervention. This approach aligns with the overarching goal of mitigating the risk of diabetes and its associated complications, thereby improving patient outcomes and reducing the burden of this global health challenge.
