Blood glucose level charts help diabetics determine if their glucose levels are within a healthy range during self-testing, reports WebMD. Diabetics check their glucose levels before or after they engage in various activities, points out Mayo Clinic. Health care providers set specific levels and times for testing for individuals based on a number of factors.
Factors that affect optimal blood glucose levels for diabetics include the type of diabetes, the severity of the disease, the duration of the diabetes and the presence of complications, explains Mayo Clinic. Other considerations include a patient's age, condition of pregnancy and overall health. Those with Type 1 diabetes may have to self-test their blood sugar levels and compare them with their charts four to eight times a day, while those with Type 2 diabetes may only need to test themselves two or more times a day. Typical times for testing may include before eating, before and after vigorous activities, and before bedtime.
Diabetics can measure their blood glucose levels using glucose meters, states Mayo Clinic. The meters read disposable test strips onto which diabetics place a drop of their blood, explains the U.S. Food and Drug Administration. The devices then use chemicals, electricity or light to analyze the blood. Because there are a number of types of glucose meters on the market, diabetics should consult with their health care providers about the meter that best suits their needs.
