Self-monitoring of blood glucose (SMBG) with home blood glucose monitors is essential. The blood glucose (BG) results are used to assess the efficacy of therapy, and to provide data by which to make management decisions. Typically, patients who use insulin should be SMBG at least 3-4 times per day. Some type 1’s check as much as 6-8 times per day.† Individuals with type 2 diabetes should SMBG, but if well controlled they may need somewhat less frequent checks. Patients on diet therapy without medications may only need to check BG a few times per week. Type 2’s using oral agents should check at least 1-2 times daily, and vary the times.
When BG control is sub-optimal, frequency of monitoring should be increased to provide data for therapy changes. To assure proper technique, patients should receive training on meter use.
