4 Common Blood Tests for Diabetes

  • HbA1c Test

An HbA1c test determines sugar levels in the body. It checks for average sugar levels for the past 2 – 3 months. The test is recommended for diagnosing and monitoring blood sugar mainly in type 2 diabetes. Unlike other blood tests, this test does not require fasting and is a good marker for long-time sugar control. An A1c level below 5.7% is normal, 5.7%–6.4% indicates prediabetes, and 6.5% or more indicates diabetes.

  • Fasting Plasma Glucose Test

This is a simple and common way to diagnose prediabetes, diabetes or gestational diabetes. The abnormal test results mean that the patient has an alteration in blood sugar levels. This test requires at least 8 to 12 hours of fasting. A fasting blood sugar level of 99 mg/dL or lower is normal, 100–125 mg/dL indicates prediabetes, and 126 mg/dL or more indicates diabetes.

  • Postprandial Plasma Glucose Test

Testing blood glucose levels after 2 hours of having a meal is called postprandial blood sugar (PPBS) test. It checks how your body utilizes glucose after a meal. Normally, PPBS level less than 140 mg/dL is normal and that less than 180 mg/dL indicates diabetes.

  • Random Plasma Glucose Test

Random Plasma Glucose Test allows for determining the level of blood glucose in the body at any time, no matter when one ate last. If your random plasma glucose levels are 200 mg/dL or above, it suggests diabetes.

Diabetes does not have a cure, but the good news is it’s absolutely manageable (or preventable if you don’t have it) with healthy lifestyle choices and regular health checkups. Keep your glucose in check to be in charge of life.
