Is the finger the only place to check blood sugar?

People do not need to prick a finger to test their blood sugar levels, but finger pricks may be useful to calibrate the device. According to an older study , a person has to put the CGM sensor under the skin of the abdomen, buttocks, thighs, or upper arm to test for glucose in interstitial fluid and other tissue.

Can you test blood sugar from your thumb?

That's why most blood glucose meters now offer the option of using blood from the fingertips, palm, upper arm, forearm, calf, or thigh, with some limitations.

Why is it important to wipe away the first drop of blood?

The first drop of blood from a lancing site contains a greater volume of platelets, which could make the lancing site seal up before enough blood was obtained for the test, and the dual wipe ensured a longer, larger flow of blood.

Why do I wake up at 3am blood sugar?

How do I check my blood sugar without a needle?
