Fasting blood glucose test instructions

Common Questions and Answers about Fasting blood glucose test instructions


Avatar m tn I'm having some blood work done that will include a glucose test. The requisition form includes instructions to fast for 12 hours prior to the test, but does not mention anything about tobacco use, and I do unfortunately smoke. Perhaps to be safe I should abstain from smoking as well as food prior to the test, as nicotine could affect my blood glucose levels. But on the other hand, doesn't *nicotine withdrawal* also affect blood glucose levels?
10881528 tn?1423629432 You should not eat before. Only drink water. You are supposed to take the test while fasting.
Avatar f tn I'm so pissed my doctor sent to do a blood glucose test gave me instructions not to fast and now that I got here the nurse told me I have to fast for it to be correct... like what the f***... has anyone had to take that 3 hours test cause of not fasting??
Avatar f tn In going for my glucose test tomorrow and I was wondering if it was OK to eat before the test or not. I have heard it was ok but I have also heard that you shouldn't because it will mess the test up. What should I do?
Avatar n tn in blood glucose readings, does that mean my 79 random blood glucose test is A LOT higher than that? And if I WAS fasting for that exam (it was a few months ago, believe it might have been a morning appointment), what does that mean in terms of the false decrease? Does anyone have any realistic/substanial evidence/knowledge on this?
1452593 tn?1285187324 Two hour PC (Postprandial glucose test) where they make you fast for 8 hours, take a blood sample to get your glucose reading, and then you eat a meal and then they test your blood-sugar again (another blood sample). You have to do insulin or your sugar goes through the roof. Beats me....
Avatar n tn The best thing you can do to help your self is test, test, test your blood glucose. Test before a meal to get a reference range. Then test 2-3 hours after a meal to see how the foods you consumed affected your blood glucose levels. Avoid/eliminate or cut way back on those that elevate your range above normal. After meals aim for less than 140 mg/dl or 7.78 mmol/l.
7559220 tn?1393617158 Im going in for a one hour glucose test and i was wondering what i can and cannot eat for breakfast, i really want a bowl of fruit loops.
1674823 tn?1307263620 I have an issue regarding blood glucose. Over the years all my fasting blood tests have been fine, but I have noticed once or twice highish readings in the emergency room, and yesterday 8.6 in the walk in clinic. I decided to get a meter and have tested today 4 hours after my light lunch it was down to 5.9 and 2 hours after my evening meal 11.0. I will check again in a while and first thing in the morning.

Avatar f tn Hi ladies, just a quick one I went for my routine blood test a couple of days ago and have been asked to go back for futher investigation and have a glucose test?? Obviously im aware this must be because my blood sugar is maybe to high. But was just wondering if anyone had any simular experiences as im a bit of a worrier and wanted to do my best for my little princess on the way.
490398 tn?1319940717 This is NOT a fasting glucose. My dad is diabetic and he has all of the tools to test blood. He has regular diabetes not Type 2 but it usually skips a generation. I had blood taken at the doctor last week, again, not fasting, for other health problems and it came back at 169. My doc obviously wants to retest me when I've been fasting and get an A1c.
180395 tn?1287493997 " Are these levels normal?" First, I'm glad you posted for the chance of diabetes are greater when the parents have it. What you need to do today is change doctors and find one that will listen to you, offer advice, and not ignore your health. Unfortunately not all doctors follow their "hippocrates oath" and it appears yours is in this category. Ask your doctor to test your glucose (blood sugar) with an OGTT (oral fasting glucose and an A1c test.
Avatar n tn A fasting glucose test will give a fairly accurate reading of the amount of excess glucose floating around your blood streams. A measurement of 5.0 mmol/l is considered normal, not diabetic.
Avatar f tn Hello~I am not a doctor or lab technician, so I really can not give you a clear answer on this. However, I am wondering if this test was "fasting" or "non-fasting" If fasting, the glucose looks a wee bit high to me, not much, but higher than most doctors like it to be if you are fasting, the desired levels are under 100.
Avatar n tn In the event that you had a fasting blood glucose test, a dimension somewhere in the range of 70 and 100 mg/dL (3.9 and 5.6 mmol/L) is viewed as ordinary. In the event that you had an arbitrary blood glucose test, an ordinary outcome relies upon when you last ate. More often than not, the blood glucose level will be underneath 125 mg/dL (6.
975514 tn?1324997938 I recently had a blood test, which included a glucose test. I wasn't fasting. I ate a bowl of whole grain cereal at about 5AM. My test was a 10AM. My uncle has diabetes and my sister is hypoglycemic. I know I get sick if I have a shake from McDonalds, but that's about it. I get really tired and nauseated. I don't drink sugary beverages at all just because I am always watching my weight, but I wonder now how that would effect me?
Avatar f tn Doctor's give different instructions. My ob office said eat whatever but the hospital said to fast...both for the same test. There is no way to 'beat' the glucose test though. Even if one passes due to fasting, fetal weight gain and physical symptoms will catch GD if it's there. Also, GD can show up at anytime so testing at specific weeks is purely precautionary and not a good indicator that one who passes will not develop GD.
Avatar n tn My blood glucose was 95 after an overnight fast. I ate a bowl of Fiber One cereal for breakfast, and 70 minutes afterward my glucose was up to 146. Then three hours later it was 118. Is this prediabetic?
194838 tn?1303428544 to get labs done, especially if you have diabetes, they will most likely want to do a cholesterol test, which IS a fasting test. This test will be very good info for keeping up with your overall health. If I were you, I would just skip breakfast or lunch, whatever is closer to your app.
