Common Mistakes to Avoid

When using a blood sugar record, avoid these common mistakes:

  • Inconsistent Testing: Skipping tests or testing at irregular times can lead to inaccurate data.
  • Incomplete Information: Failing to record relevant details makes it difficult to identify the causes of blood sugar fluctuations.
