FPG value at or above which requires clearance before treatment?

• A. 126
• B. 160
• C. 140
• D. 180

Answer: (B)

Fasting plasma glucose thresholds are used to gauge how well a patient’s diabetes is controlled and whether medical clearance is needed before procedures. When the fasting glucose level reaches 160 mg/dL or higher, this indicates significant hyperglycemia that raises the risk of perioperative instability, dehydration, infection, and poor wound healing. In such cases, obtaining medical clearance allows a physician to reassess and optimize glycemic control before proceeding with treatment, reducing the risk of complications. A value of 126 mg/dL or higher is a diagnostic cutoff for diabetes rather than a clearance trigger, and 140 mg/dL sits in the impaired fasting glucose/prediabetes range. A threshold like 180 mg/dL may be used in some settings for more urgent management, but the commonly cited clearance threshold in this context is 160 mg/dL.
