CGM vs. Finger Stick Monitoring
Blood sugar monitoring technology has expanded significantly beyond traditional finger stick testing.
Finger stick testing
Provides a single point-in-time reading, requiring a small blood sample each time.
Continuous glucose monitors (CGM)
Provide real-time, continuous data throughout the day and night via a small sensor worn on the body.
Choosing between them
CGMs offer richer data and convenience at a higher cost, while finger sticks remain a reliable, more affordable option for some.
Key takeawayCGMs offer far richer, continuous data than finger sticks, particularly valuable for spotting patterns, though cost and personal preference still make finger sticks a reasonable choice for some.
