who do not self-adjust their drug dosage will miss many of the benefits of self-testing, and so it is questionable in this group. This is particularly so for patients taking monotherapy with metformin who are not at risk of hypoglycaemia. Regular 6 monthly laboratory testing of HbA1c (glycated haemoglobin) provides some assurance of long-term effective control and allows the adjustment of the patient's routine medication dosages in such cases. High frequency of self-testing in type 2 diabetes has not been shown to be associated with improved control. The argument is made, though, that type 2 patients with poor long term control despite home blood glucose monitoring, either have not had this integrated into their overall management, or are long overdue for tighter control by a switch from oral medication to injected insulin. Continuous Glucose Monitoring (CGM) CGM technology has been rapidly developing to give people living with diabetes an idea about the speed and direction of their glucose changes. While it still requires calibration from SMBG and is not indicated for use in correction boluses, the accuracy of these monitors is increasing with every innovation. The Libre Blood Sugar Diet Program utilizes the CGM and Libre Sensor and by collecting all the data through a smartphone and smartwatch experts analyze this data 24/7 in Real Time. The results are that certain foods can be identified as causing one's blood sugar levels to rise and other foods as safe foods- that do not make a person's blood sugar levels to rise. Each individual absorbs sugar differently and this is why testing is a necessity. HbA1c test A useful test that has usually been done in a laboratory is the measurement of blood HbA1c levels. This is the ratio of glycated hemoglobin in relation to the total hemoglobin. Persistent raised plasma glucose levels cause the proportion of these molecules to go up. This is a test that measures the average amount of diabetic control over a period originally thought to be about 3 months (the average red blood cell lifetime), but more recently thought to be more strongly weighted to the most recent 2 to 4 weeks. In the non-diabetic, the HbA1c level ranges from 4.0 to 6.0%; patients with diabetes mellitus who manage to keep their HbA1c level below 6.5% are considered to have good glycemic control. The HbA1c test is not appropriate if there has been changes to diet or
