what is mg dl mean

mg/dL stands for milligrams per deciliter. It is a unit of measurement used to indicate the concentration of a substance (such as glucose) in a specific volume of blood. For example, blood sugar levels are often measured in mg/dL. Here's a quick breakdown:

• mg: Milligrams, a unit of mass.
• dL: Deciliter, a unit of volume (1/10th of a liter).

In the context of blood sugar, a normal fasting blood glucose level is typically 70–99 mg/dL, while levels above this range may indicate prediabetes or diabetes.
