For patients with diabetes mellitus type 2 , the importance of monitoring and the optimal frequency of monitoring are not clear. A 2011 study found no evidence that blood glucose monitoring leads to better patient outcomes in actual practice.  One randomized controlled trial found that self-monitoring of blood glucose did not improve glycosylated hemoglobin (HbA1c) among "reasonably well controlled non-insulin treated patients with type 2 diabetes".  However a recent meta-analysis of 47 randomized controlled trials encompassing 7677 patients showed that self-care management intervention improves glycemic control in diabetics, with an estimated % (95% CI, -) reduction in their glycosylated hemoglobin values.  Furthermore, a recent study showed that patients described as being "Uncontrolled Diabetics" (defined in this study by HbA1C levels >8%) showed a statistically significant decrease in the HbA1C levels after a 90-day period of seven-point self-monitoring of blood glucose (SMBG) with a relative risk reduction (RRR) of % (95% CI, -%, p<.001).  Regardless of lab values or other numerical parameters, the purpose of the clinician is to improve quality of life and patient outcomes in diabetic patients. A recent study included 12 randomized controlled trials and evaluated outcomes in 3259 patients. The authors concluded through a qualitative analysis that SMBG on quality of life showed no effect on patient satisfaction or the patients' health-related quality of life. Furthermore, the same study identified that patients with type 2 diabetes mellitus diagnosed greater than one year prior to initiation of SMBG, who were not on insulin, experienced a statistically significant reduction in their HbA1C of % (95% CI, - - -) at six months follow up, but a statistically insignificant reduction of % (95% CI, - – ) at twelve months follow up. Conversely, newly diagnosed patients experienced a statistically significant reduction of % (95% CI, - – -) at 12 months follow up.  A recent study found that a treatment strategy of intensively lowering blood sugar levels (below 6%) in patients with additional cardiovascular disease risk factors poses more harm than benefit.  For type 2 diabetics who are not on insulin, exercise and diet are the best tools.

Insulin-dependent type 2 diabetics do not need to monitor their blood sugar as frequently as type 1 diabetics.
When immediate blood transfusion or replacement is required, knowing your blood type can save your life. Unfortunately, many surveys indicate that a high percentage of people do not have their critical blood type group information because either they don't ask or they forget when the medical professionals communicate their patients with their blood type information. The EldonCard blood typing kit uses the basic forward antibody method of blood hematology to easily and quickly provide the user with their blood type (A, AB, B or O) and rhesus factor (Rh negative or Rh positive) in a few minutes without the need for special laboratory supplies or training.
