Fasting Glucose — Baseline Metabolic Marker — 60-Second Protocol

The protocol

Units	mg/dL
Standard range	70–99 (normal); 100–125 (prediabetes); ≥ 126 on two separate tests (diabetes) — per MedlinePlus and NIDDK (ranges vary by lab)
<70	may be normal for some people, mainly those who are thin and young — discuss with your clinician
70-99	normal
100-125	prediabetes (impaired fasting glucose)
≥126	diabetes range — confirmed by a repeat test on a different day; see your clinician
Testing	a result in the prediabetes or diabetes range is confirmed with a repeat test on a different day; the A1C test (no fasting needed) can be used alone or with other tests
Preparation	fast for at least 8 hours before the draw (water only); the test is most reliable in the morning
Clinician	discuss any result outside 70–99 mg/dL with your clinician

Full transcript

The cheapest metabolic number on your panel, and the one most people read too generously. Plasma glucose after an eight to twelve hour fast. Seventy-five to ninety is optimal. Ninety to ninety-nine is inside the normal range but trending, and worth pairing with fasting insulin. One hundred to one twenty-five is pre-diabetic. One twenty-six or above on two readings is diabetes, and that one goes to a clinician. It is less sensitive than fasting insulin to early trouble, but it is on every basic panel — so it is the number you already have. agegen.ai. Generate your prime age! ~~ Mr. Age
