Should I use alcohol wipes before testing 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.

Can alcohol hand sanitizer affect blood sugar readings?

Instant hand sanitizers did not adversely affect the test strip chemistry of a blood glucose monitoring system. Instant hand sanitizers perform a dilution of preexisting sugar-containing compounds and may or may not minimize interference from exogenous glucose prior to blood glucose monitoring.

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.

What Does Alcohol Do to Your Blood Sugar?

What can throw off a glucose test?

Don't eat high-sugar foods or simple carbs (including refined grains) the morning of your glucose screening. The body breaks these foods down quickly, leading to a spike in blood sugar levels. That means avoiding foods such as: Orange juice and other fruit juices.

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

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).

Can alcohol swab affect blood alcohol test?

What is a good blood sugar reading in morning?

What we call fasting blood sugar or blood glucose levels is usually done six to eight hours after the last meal. So it's most commonly done before breakfast in the morning; and the normal range there is 70 to 100 milligrams per deciliter.

Should I wash my hands before I check my blood sugar?

The implications of this small study are clear: having residual fruit sugar on your fingers can artificially elevate blood glucose readings, and alcohol swabs are not the best way to clean your hands before performing the test. A thorough hand washing with soap and water is always best.

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.
