About this test
Measures the sugar in your blood at the moment of the draw. Fasting, it is a standard screen for prediabetes and diabetes risk.
A1c shows your three-month average blood sugar, which is why it is commonly rechecked. Fasting glucose and insulin add a view of how your body handles sugar day to day.
Together they are the standard picture of metabolic health. Fasting matters for glucose and insulin; A1c does not need it.
Reading your result
Fasting glucose rises with insulin resistance, weight gain, illness, steroid medicines, and poor sleep, and falls with weight loss, activity, and diabetes medicines. Eating within eight hours of the draw is a common reason for a high value.
One reading is a snapshot, so a borderline value is usually repeated or read against A1c, which reflects three months and is not affected by the morning's breakfast or a poor night of sleep.
