Fasting Insulin Blood Test

Measures

Insulin after an overnight fast.

Why it matters

Insulin is the hormone that moves glucose out of the blood and into cells. Measuring it fasting, alongside fasting glucose, describes how much insulin is required to hold glucose where it is.

That relationship is more informative than either value alone, which is why the two are usually ordered together.

Before you collect
