Common Questions and Answers about How many hours for blood fasting test


Avatar f tn Am due for glucose testing. Im really hungry how many hours in between do i need to fast to be sure the test comes out right .
Avatar m tn That's why a fasting blood test usually requires that you avoid all food and drinks except water for 12 hours before your screening. It's also advised that you avoid alcohol for 24 hours before your fasting blood test, as well as any strenuous exercise.
Avatar n tn My one hour test glucouse result a little high at 143. Dr. schedule for 3 hours test, will my baby ok if I have a high glucouse?
Avatar f tn NO fasting is fasting 12 hours or 16 hours its still fasting. no error because you fasted for 15 instead of 12 hours.
Avatar f tn A lot of doctors are now just taking a blood sample for a test called A1C. The A1C test is a common blood test used to diagnose type 1 and type 2 diabetes and then to gauge how well you're managing your diabetes. The A1C test goes by many other names, including glycated hemoglobin, glycosylated hemoglobin, hemoglobin A1C and HbA1c. The A1C test result reflects your average blood sugar level for the past two to three months.
Avatar n tn Thanks for help...agree on advice, but any idea whgy my fasting blood glucose would go UP (in the 8-12 hour is that possible if I hadn't eaten anything? Was it because fast TOO? Thanks.
Avatar f tn 30am- 1:00pm. I stay up late at night.

The thing is that many many people who ARE celiac test negative with the blood tests (which is what happened with my brother) and the only positive test is the biopsy of the small intestine... PROBLEM IS, that if you've been gluten free for a while, your test will come back negative no matter what. In order for your biopsy to come back positive there must be damage to the intestine villi....
Avatar n tn Islam is a understanding religion and does not want people to harm them self, so its does say if you feel ill, or the fasting could be harmful for the mother or for the baby or if it is too much for the mother and not because of lazyness, they are allowed not to fast. But they have to make up for the missed fast before next Ramamdan. So to answer your question go to your doctor to check your and yout baby health and if fasting will be bad for health with the respect of your religion.
Avatar n tn To know how many carbs you can eat . test BG before eating (gives a base line) count how many carbs your going to eat. test 1 hour and 2 hours after eating take the highest reading. Ideally you want your BG not over 140 and or no more than a 40 pt rise. If you constantly have the hirer reading at 1 hour you can stop the 2 hour test and vise versa.
Avatar n tn Type 1's on the other hand experience much more in the way of both highs and lows and keeping blood sugar in target range is a constant effort for many. Type 1.5's as you say, have the most difficult time managing blood sugar because their own pancreas is still producing insulin and sometimes does so in spurts making insulin doses difficult to determine consistently. It would be nice if insulin dosing were an exact science, but it isn't.
Avatar m tn I agree with diabetes86, that you should check your 1 1 /2 - 2 hours post eating blood sugars to see how high you are actually going. For many people who are developing diabetes, their fasting blood sugar will remain "normal' much longer than their post eating levels (after all their bodies have 8 - 10 hours overnight to try to correct their sugar levels).
Avatar m tn But you should discuss your concerns with the doctor (or the nurse) who ordered the test. Why were you having the Fibrosure test? Have you had hep c for many years? I have read that in general for patients infected with hep c only about 20% will develop advanced liver disease after 20 years of infection. I know for me I was infected for 30 years before I was diagnosed with cirrhosis in 2008.
Avatar f tn Post prandials depend on when you test and how many carbs you eat. This pp is normal. His fasting is a bit elevated and would be considered pre-diabetes. The doctor might do further testing to clarify such as an A1C which measures all the blood sugars for about a two month period or an OGTT which measures his response to a sugary drink over a couple hours.
1727909 tn?1314848810 Your fasting is high the 170 means you cant eat that many carbs (BG over 140 is bad for your long term health) 65 means probably you went MUCH higher and your pancreas over compensated what is your idea of a "healthy meal" ? For me that would be prime rib and salad. To me your numbers mean your pancreas is not working correctly. A better test I think is what is the highest your BG went after each of your tests.
Avatar f tn I tell you, whether you realize it or not, STRESS is the reason for many of us having PVCs. The reflux will cause them just as quick for me. I take Zantac 75 . One in the morning and one just before bedtime. I eat smaller meals and I NEVER...NEVER allow any caffine in my body.I strictly limit my sugar intake and rarely ever eat fried food. The healthier we are the better our bodies can handle the stresses and demands we put on it.
Avatar n tn On my Lab slip for thyroid test my doctor puts no fasting. I do anyway because I have the test done early in the AM as soon as they open and depending where I am at in line. Hypos need their Labs done as late as possible in the day for that is when they are the most hypo. And no fasting necessary, I would assume, unless the doctors office tells you otherwise.
Avatar m tn Thanks Wave Yours suggestion matters for me i have planed to take lesser calorie food for 1 week and then will try to take fasting test again
Avatar m tn I think the primary reason for fasting is the blood glucose test. I doubt that eating would affect LFTs. "...For example, males have higher transaminase levels than females. And, African-American men have higher AST levels compared with Caucasian men. Even the time of day that a blood sample is drawn may influence the level of transaminase elevation. People appear to have higher transaminase levels in the morning and afternoon than in the evening.
Avatar f tn Most physicians, unless they are specifically trained in the pharmacology of opioids, are unfamiliar with UDT results, and therefore accept them as fact, as if they would a blood sugar result, knowing well that a simple blood glucose level can have false readings depending whether or not the patient was fasting for 12 hours prior to the test. This is also from the FSMB document: "Test results that suggest opioid misuse should be discussed with the patient.
Avatar m tn And if i dont go and i over eat, i will get really sick basically, i'll over eat then feel nausea for hours and hours, when i finally do have the urge to throw up, its dry heaving hours later. This landed me in the hospital once with the same symptoms and xrays basically confirmed i was packed from stem to stern. Lately if i over ate, i would drink a glass of prune juice and 30 min later work out. Then it would kick in and i would feel fine and have a bowel movement the next day.
535882 tn?1396580285 Sorry about the bad glucose example…I was referring to fasting for an entire day (24 hours) before the draw (similar to d/cing your meds for 24 hours before). If fasting all day is not your usual routine, then you are going to be skewing the test by doing so, since on a daily basis, you eat. Your glucose level as tested is virtually useless. I’m making the distinction between something that really lowers FT3 levels and something that might cause the test to return a falsely low level.
Avatar n tn Continue to work with them and ask as many questions as you have as your doctor is best to guide you. Normal fasting blood sugar levels is 72 to 100 for the average person. Yours are slightly elevated at 103. This would mean that you should begin watching this to make sure they don't continue to rise and to see if you can impact it to lower the number. Ways to do so naturally are through diet including cutting back on sugar and carbs as well as increasing your exercise.
Avatar n tn Hi cat Did your Doctor or your diabetic educator give you instructions for testing? Often the minimum is to test your fasting blood sugar when you first get up and then test two hours after breakfast. Then write down these numbers so your Doctor can see how your meds are working when you return for follow up. I'm assuming you are relatively recently diagnosed though, so testing is also an opportunity to learn more about your own particular version of this disease.
Avatar m tn I just got back from seeing the doctor and I had him do some blood work on me. He said everything in my blood work looked good except for my Uric Acid. He said it was quite high and was something that needed to be looked at. I'll be honest and say I have no idea what a high Uric Acid does or means besides gout. I'm not even sure what gout is besides something my brother talks about when we talk about food.
Avatar n tn Hello, So I 've been told by my doctor that my glucose levels in urine have been rising.Also that blood glucose test you do at forgot how many weeks,she said I passed it,but very close to not passing. I do not think the way they measure it in the doc's office is very accurate, by using strips put into urine. I have done some checking myself at home,by pricking the finger before and after each meal. On empty stomach in the morning,my number was 4.0.
Avatar m tn May I presume this is a fasting result? The Hba1c is slightly high, but the fasting blood sugar is high enough to put you in the prediabetic range. Triglycerides are high, HDL is low. You are likely in early stages of diabetes. To address this:- 1. Low carb, moderate protein, higher fat (fat is for added calories / replace the carbs reduced). The high triglycerides should also improve on a lower carb diet. Paleo or mediteranean style (without the bread/pasta/potato) are a good approach.
Avatar m tn I have just starting testing my blood glucose Do I need to test every day or weekly ?
