Insulin-dependent patients ideally should test their plasma glucose daily before meals, in some cases 1-2 hours after meals, and at bedtime. In practice, however, patients often obtain 2-4 measurements each day, including fasting levels and levels checked at various other times (eg, preprandially and at bedtime).
