what can cause a false high glucose reading

Several factors can lead to a falsely high glucose reading. These include:

• Improper Meter Use: Not following the instructions for your glucose meter, such as using expired test strips or not cleaning your hands before testing.
• Dehydration: Low fluid levels in the body can concentrate blood sugar, leading to higher readings.
• Certain Medications: Some drugs, like corticosteroids or beta-blockers, can increase blood sugar levels.
• Stress or Illness: Physical stress, such as an infection or surgery, can temporarily raise blood sugar levels.
• Food Contamination: Testing immediately after eating without washing hands can result in a false high reading due to food residue.

If you suspect a false high reading, retest after ensuring proper technique and consult your healthcare provider if readings remain inconsistent.
