Like "Howdy Leslie, WELCOME to DiabeticConnect! The minimum you should be testing per day is 3 times per day. 1st fasting ( after you get up from bed ) 2 hours ("post prandial") after any meal you choose, (can be rotated to different meals on different days) and just before going to bed, so you aren't too low at night. Praying God's richest blessings on you and yours, Leslie James"
