Some CGMs have a warm-up window before readings are available. A meter can help cover that gap when a care plan calls for a check.
CGM backup guide
Do CGM users still need a fingerstick meter?
Yes.
A CGM can be the everyday view, but a fingerstick meter is still useful when symptoms do not match the reading, when a sensor is warming up or unavailable, while waiting for a replacement, during travel, or when a care plan asks for a confirmatory blood glucose check.

CGM users may still need a fingerstick meter as a backup.
A fingerstick blood glucose meter can be useful for CGM users when symptoms do not match sensor readings, during sensor warmup, while waiting for a replacement, when a sensor fails or is unavailable, during travel, or when a healthcare professional's care plan calls for a confirmatory blood glucose check.
When this matters
Four moments when backup testing can make the routine clearer.
CGMs and fingerstick meters can play different roles in diabetes care. This page is not medical advice, but these are common moments when people are told to keep a meter nearby.
If someone feels different than the CGM reading suggests, many device makers and care teams recommend confirming with a blood glucose meter.
Adhesive, signal, sensor, or app issues can interrupt CGM data. A backup meter helps keep a simple check available.
A compact kit can be kept in a bag, car, classroom, work drawer, or caregiver pouch for times when the main setup is not nearby.

CGM + fingerstick
Not either-or. More like everyday view plus backup check.
A CGM shows glucose trends over time. A fingerstick meter checks a blood sample at a specific moment. Many people keep both in the routine for different reasons.
CGM
Helpful for ongoing visibility, trend arrows, alerts, and pattern awareness.
Fingerstick meter
Helpful for backup checks, confirmatory readings, sensor gaps, and travel kits.
