I had blood drawn and tested on Thursday last week.  I was at the doctors office for follow up on medications I am taking and the doctor only asked that my blood be tested because it had been over a year since it had been. That morning right before I arrived at the doctors office, I had a trail mix granola bar, a banana and 2 cups of coffee.Today the doctors office called and asked me to come in and have the 2 hour fasting glucose test.  My blood tests said that my blood sugar that morning had been 160 (which the nurse said was high).  I had my glucose tested about 9 months ago and everything was fine.  Do you think it is necessary to have another glucose test done?
Hi, Thanks for asking. Based on your query, my opinion is as follows.1. Yes, it is necessary.2. More information can also be gathered through glycosylated hemoglobin of HbA1c evaluation.3. It can change over time and diet should not influence especially when fasting is being evaluated. 160 is too high for even post radial blood sugar levels. Do get it tested and if elevated, blood sugar control is essential. Hope it helps. Any further queries, happy to help again.
