The card shows an example result of 110 mg·dL⁻¹, which is 3.52 SD above the mean.

What it measures

The level of glucose in the blood after at least 8 hours without food. It shows how well the body keeps glucose steady between meals.

Reference range

The mean is (low + high) / 2 and the SD is (high − low) / 4, so the healthy range covers Z from −2 to +2.

Reading the result

• High — 100 to 125 mg·dL⁻¹ suggests prediabetes and 126 or more on two tests suggests diabetes.
• Low — Not the concern this panel tracks. Values below 70 mg·dL⁻¹ are hypoglycaemia and can cause symptoms.

Notes

• To convert to mmol·L⁻¹, divide by 18.
• Illness, stress, and some medicines raise it.
