Why do you get different blood sugar readings on different fingers?

Contamination of the fingers is a common culprit in blood sugar reading variability. That's because it only takes a little bit of food residue on your hands to impact blood glucose levels. For example, just touching a banana or cutting a piece of fruit can send your numbers sky high.

Can blood sugar reading be different each finger?

You may get different results than from your fingertip. Blood sugar levels in the fingertips show changes more quickly than those in other testing sites. This is especially true when your blood sugar is rapidly changing, like after a meal or after exercise.

How does squeezing finger affect blood sugar?

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 is it important to wipe away the first drop of blood after a finger stick?

Adult patients

Wipe away the first drop of blood because it may be contaminated with tissue fluid or debris (sloughing skin). Avoid squeezing the finger or heel too tightly because this dilutes the specimen with tissue fluid (plasma) and increases the probability of haemolysis (60).

Why do I wake up at 3am blood sugar?

The dawn phenomenon is a normal rise in blood sugar as a person's body prepares to wake up. In the early morning hours, hormones (growth hormone, cortisol, and catecholamines) cause the liver to release large amounts of sugar into the bloodstream.

Why is my blood sugar high in the morning when I haven't eaten anything?

In the early hours of the morning, hormones, including cortisol and growth hormone, signal the liver to boost the production of glucose, which provides energy that helps you wake up. This triggers beta cells in the pancreas to release insulin in order to keep blood glucose levels in check.

Should you use an alcohol wipe before checking blood sugar?

Cleaning the finger with an alcohol swab prior to taking a blood sample is commonly recommended as a way to make sure the test site is clean.

Is peanut butter good for diabetics?

Research has shown that peanuts can help control blood sugar in both healthy individuals and those with type 2 diabetes. Peanuts and peanut butter have even been shown to help lessen the spike in blood sugar when paired with high-carbohydrate or high-GL foods.

Fasting blood sugar (in the morning, before eating): Less than 100 mg/dL. 1-2 hours after a meal: Less than 140 mg/dL. 2-3 hours after eating: Less than 100 mg/dL.

However, depending on surface area, hand sanitizers may not be adequate for cleaning the skin prior to glucose meter testing.

What can cause false high blood sugar readings?

However, various factors such as application errors, extreme environmental conditions, extreme hematocrit values, or medication interferences may potentially falsify blood glucose readings. Incorrect blood glucose readings may lead to treatment errors, for example, incorrect insulin dosing.

How many times can you use a lancet needle?
