Fingerstick Testing More Accurate Than Tests at Alternate Sites

Because fingerstick testing generally detects low blood glucose earlier than tests performed with capillary blood from arms or thighs, alternate-site testing should be avoided when blood-

glucose levels are apt to be undergoing rapid changes, such as up to two hours after meals and after an insulin injection.

Although results vary among individuals, the pattern of site differences is consistent, say researchers at LifeScan. Fingersticks are accurate at all time points.

Fingerstick testing also should be used when hypoglycemia is suspected.
