The World Health Organization suggests using your third and fourth (middle and ring) fingers for the best glucometer test results; your palm can also be an ideal site.
Here's a breakdown of why certain fingers and sites are preferred:
-
Middle and Ring Fingers: These fingers are often recommended because they tend to have better blood flow compared to others and are less calloused than the index finger or thumb.
-
Palm: The palm can also be used as an alternative site.
