Common terms: blood sugar; blood glucose; fasting glucose; random glucose; FPG; FBS; FBG; blood sugar; blood glucose; FPG; FBS; FBG; Blood glucose; Fasting glucose; Random glucose; blood sugar blood glucose sugar test; Blood Sugar & Diabetes

Preparation: Fasting and random glucose use different collection timing. Confirm which order you have; do not fast for a random test unless instructed for another reason. Do not change medicines or supplements unless your healthcare professional tells you to.

Preparation: Confirm the laboratory’s instructions for this order. The cited catalog does not establish a universal fasting requirement. Do not change medicines or supplements unless your healthcare professional tells you to.

Important distinction: This is a shorter-term glucose marker than A1c. It measures glycated proteins and is not a direct blood-glucose measurement.
