Even with the growing popularity of continuous glucose monitors (CGMs), blood glucose meters (BGMs) remain essential for many people with diabetes. They offer fast, accurate readings using a small blood sample, often at a lower cost than CGMs. Whether you’re looking for high precision, low-cost test strips, Bluetooth connectivity, or dual glucose and ketone testing, this updated 2025 guide will help you choose the best blood glucose meter for your needs.
Why Blood Glucose Meters Still Matter
Despite advancements in CGM technology, traditional glucose meters are still widely used for:
- Backup testing when CGMs fail or are unavailable
- Spot checks for accuracy confirmation
- Ketone monitoring for those at risk of diabetic ketoacidosis (DKA)
- Budget-friendly glucose tracking
All meters sold in the U.S. must meet FDA standards and are evaluated using the ISO 15197:2013 accuracy criteria, which require 95% of results to fall within ±15% of lab values.
