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?
10881528 tn?1423633032 You should not eat before. Only drink water. You are supposed to take the test while fasting.
7559220 tn?1393620758 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.

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.
7094011 tn?1405459486 I have my glucose test tomorrow and I am super nervous! I LOVE my sweets, and espically being pregnant that's all I crave is sweets! However the receptionist at my OB office gave me my drink and gave me instructions to eat a normal breakfast, drink the drink 30 minutes before my appointment. When I've talked to so e other people they have said eating before you go could potentially make you fail the test.
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?
Avatar f tn If you need a drink just sip water. That's all. They will take your blood make you drink a glucose drink and then take your blood again 2 hours later. Unfortunately I found out I do have gestational diabetes but so far can control this through my diet.
Avatar f tn Ive had some tell me to eat something low in sugar before the test, and some tell me not to eat anything(fasting) before the test.
8650265 tn?1421569013 Before you go off calling people idiots you should look at your wording. You said how do I pass it. Since you failed it. What else are you really asking with that statement? You don't do anything to "pass it" you take the test and follow the instructions they give you to do before hand. Pretty simple.
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?
310089 tn?1232485023 You need to check with your doctor / the lab to get clear instructions. When I did the test I went to the clinic. had the first blood draw. Then had to drink the drink, then they did blood draws every hour.

1240706 tn?1331605711 A random glucose test is not a glucose tolerance test. A random glucose test is just that. They measure your blood glucose at just any time when you're eating normal meals. This does not qualify as a screening for Gestational Diabetes. Depending on how long after your last meal and what you ate, the results could be normal, even if your blood sugar is not.
1240706 tn?1331605711 If your levels are high they send you for the 3h test which is a fasting test in which you take blood on your fast. then a 75 ml drink, and then blood after 1h and blood after 2h. However even though you don't need to fast for the 1h screen you still shouldn't eat anything after drinking the solution. I don't know why I did not think of this a little better. But in my case since the levels were so high they just skipped over the 3h test and diagnosed me with GD.
341551 tn?1266984330 Fasting blood draw: less than 95 1st draw after drinking glucola: less than 180 2nd draw: less than 155 3rd draw: less than 140
Avatar f tn My doc said that if this one comes out normal it should be the last blood test I have to do...I hope so to. I hate giving away what seems to be those large vials of blood. I am not much of a needle/blood type of gal.
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?
Avatar f tn amount of water is fine... And i swear last time i did a THREE hour fasting test but this time was just a 2 hour? and i asked if it used to be a 3 hour and she started explaining the 2 hour to me so im not sure she understood what i was asking lol but anyway there wasnt an opiton for a 3 hour at all on the form...

1452593 tn?1285190924 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 f tn My 1 hour glucose test came back annormal:( I was 4 points over. I'm trying not to worry but I can't help it. Has this happened to anyone and your 3 hour test came back fine?
Avatar n tn I had recent dizzyness (usually at night), and went to my cardiologist about it, nad he took me off one of my blood pressue meds. Dizzyness seems better. They gave me a blood test, and my Glucose Serum came in at 103. It had been 87 about 3 months ago. This latest bloodtest was given to me about an hour after I had a glass of orange juice, and an english muffin with peanut butter. I believe that I had also not fasted before the blood test 3 months ago.
1428239 tn?1333460653 I am going to do my glucose tolerance test on Thursday.... I was hoping people could give me advice on how to prepare the night before and morning of... I am really nervous for it.
92903 tn?1309908311 Regarding glucose, buy a blood sugar meter and test yourself one hour after meals and again two hours after meals for several days to see how high you go. This will tell you far more than a fasting blood sugar test, which only indicates problems when you're pretty diabetic. Basically, you should not go over 140 at one hour, 120 at two. Eliminating refined sugar won't do the job. First of all, white bread, believe it or not, is way worse than any sugar.
Avatar n tn I have only heard fast for my Cholesterol 12 hours only water..Nothing bout Fasting for thyroid blood test, does it make a difference to the test? I Haven't heard dont drink before a test, but i probably wouldn't..
