Fasting Glucose Wellness Check
A fasting glucose wellness check screens morning trends after an overnight fast—interpret trends with your clinician, not a single home reading.
A fasting glucose wellness check is a morning reading after eight or more hours without food—often at an annual physical or with a home meter—to screen trends, not to label yourself from one number. Dawn hormones, poor sleep, and late dinners can elevate mornings even when daytime habits are solid.
Compare trends with your clinician; prediabetes and diabetes thresholds are medical interpretations.
Common questions
-
Does one high fasting glucose mean prediabetes?
Not necessarily—illness, stress, and sleep loss can skew a single draw. Clinicians usually confirm with repeat labs or A1C before labeling prediabetes.
