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.
