As part of my initial new gp apt nurse did dip test and asked if I was diabetic as glucose in sample. Asked go back next morning for fasting bloods and to produce another sample. Different nurse - didn't have time to dip, said would do later as too many patients waiting. Anyway I phoned later and receptionist said "no abnormalities" sample sent off with the bloods. QUESTION. Is It possible to have glucose present at 4pm but absent 9am following day?? Or did she bother dipping?
