Fasting plasma glucose — lab reference

Purser Wellness approved rule

Unit: mg/dL

Male: <100

Female: <100

How to read this marker

Normal <100; prediabetes 100-125; diabetes ≥126 on confirmatory testing unless unequivocal hyperglycemia.

The wider testing context

ADA diagnostic decision thresholds are shown where established. They are not ordinary statistical reference intervals.

Using this reference

This is the approved adult, nonpregnant baseline unless the rule explicitly states otherwise. Keep the performing laboratory’s reference interval separate from this Purser Wellness rule. Match units and review the specimen, method, timing, medicines and relevant clinical context before interpreting a result. These pages do not calculate a personal high/low status or prescribe treatment.
