Blood glucose testing is typically done on the fingertips due to their abundant capillary blood supply, which helps obtain accurate results. However, alternative testing sites are available for those who find fingertip testing uncomfortable or need to test frequently. These alternative sites are known as "alternate site testing" (AST). Remember that blood glucose levels at these sites may differ slightly from fingertip levels, particularly during rapidly changing blood glucose levels.
Some alternative sites for blood glucose testing include:
Palm (base of the thumb): The fleshy area on the palm, close to the base of the thumb, is rich in capillaries and can provide a suitable blood sample. This site is less sensitive than fingertips and often less painful.
The outer aspect of the hand (side of palm): This fleshy area has many capillaries and is less sensitive than the fingertips.
Upper Forearm: The forearm is another commonly used alternate site. Choose an area on the inner forearm with sufficient fatty tissue and avoid areas close to the bone. The forearm may be less painful than the fingertip, but it's essential to apply pressure after testing to minimize bruising.
Upper arm: The upper arm can also be used for blood glucose testing. Select a spot on the back of your upper arm with adequate fatty tissue. This site is generally less sensitive than fingertips. This is the most common site for continuous glucose monitoring, which uses a longer needle to tap into a blood supply sufficient for ongoing sampling. You may get different results using a lancet device.
Thigh: Find the fleshiest part of your thigh. If you have muscular thighs, this may not be an appropriate option for you.
Consult with your Revero coach
It's essential to discuss alternate site testing with your Revero Health Coach to determine if it's appropriate for your specific situation, as there may be differences in blood glucose readings between the fingertip and alternate sites.
