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


Hi, I just recently had a f<span style = 'background-color: #dae8f4'>a</span>sting <span style = 'background-color: #dae8f4'>blood</span> <span style = 'background-color: #dae8f4'>test</span>. That morning, about 3 <sp<span style = 'background-color: #dae8f4'>a</span>n style = 'b<span style = 'background-color: #dae8f4'>a</span>ckground-color: #d<span style = 'background-color: #dae8f4'>a</span>e8f4'>hours</sp<span style = 'background-color: #dae8f4'>a</span>n> before the test, I engaged in a 25 minute jog ( 5.5mph, as I do nearly every morning). Unfortunately, no one had informed me that I should abstain from exercise prior to bloodwork like this. So I'm wondering, an style = 'background-color: #dae8f4'>howan> would exercise affect my results? Of particular (though not exclusive) interest are the following: -> Triglycerides (Total was 39. Normally it's around 50 for me, so this is an obvious improvement.
Thanks for help...agree on advice, but any idea whgy my f<span style = 'background-color: #dae8f4'>a</span>sting <span style = 'background-color: #dae8f4'>blood</span> glucose would go UP (in the 8-12 hour style = 'background-color: #dae8f4'>howan> is that possible if I hadn't eaten anything? Was it because fast TOO? Thanks.
30am- 1:00pm. I stay up late at night.
and yes, SOMETIMES there is a correlation between autoimmune celiac and autoimmune thyroid problems. The thing is that <sp<span style = 'background-color: #dae8f4'>a</span>n style = 'b<span style = 'background-color: #dae8f4'>a</span>ckground-color: #d<span style = 'background-color: #dae8f4'>a</span>e8f4'>m<span style = 'background-color: #dae8f4'>a</span>ny</sp<span style = 'background-color: #dae8f4'>a</span>n> <sp<span style = 'background-color: #dae8f4'>a</span>n style = 'b<span style = 'background-color: #dae8f4'>a</span>ckground-color: #d<span style = 'background-color: #dae8f4'>a</span>e8f4'>m<span style = 'background-color: #dae8f4'>a</span>ny</sp<span style = 'background-color: #dae8f4'>a</span>n> people who aRE celiac <span style = 'background-color: #dae8f4'>test</span> negative with the <span style = 'background-color: #dae8f4'>blood</span> 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....
Islam is a understanding religion and does not want people to harm them self, so its does say if you feel ill, or the f<span style = 'background-color: #dae8f4'>a</span>sting 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.
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 <sp<span style = 'background-color: #dae8f4'>a</span>n style = 'b<span style = 'background-color: #dae8f4'>a</span>ckground-color: #d<span style = 'background-color: #dae8f4'>a</span>e8f4'>m<span style = 'background-color: #dae8f4'>a</span>ny</sp<span style = 'background-color: #dae8f4'>a</span>n>. Type 1.5's as you say, have the most difficult time managing <span style = 'background-color: #dae8f4'>blood</span> 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.
I agree with diabetes86, that you should check your 1 1 /2 - 2 <sp<span style = 'background-color: #dae8f4'>a</span>n style = 'b<span style = 'background-color: #dae8f4'>a</span>ckground-color: #d<span style = 'background-color: #dae8f4'>a</span>e8f4'>hours</sp<span style = 'background-color: #dae8f4'>a</span>n> post eating <span style = 'background-color: #dae8f4'>blood</span> sugars to see <sp<span style = 'background-color: #dae8f4'>a</span>n style = 'b<span style = 'background-color: #dae8f4'>a</span>ckground-color: #d<span style = 'background-color: #dae8f4'>a</span>e8f4'>how</sp<span style = 'background-color: #dae8f4'>a</span>n> high you are actually going. For an style = 'background-color: #dae8f4'>manyan> 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 an style = 'background-color: #dae8f4'>hoursan> overnight to try to correct their sugar levels).
Your fasting is high the 170 means you cant eat that an style = 'background-color: #dae8f4'>manyan> 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.
I tell you, whether you realize it or not, STRESS is the reason for <sp<span style = 'background-color: #dae8f4'>a</span>n style = 'b<span style = 'background-color: #dae8f4'>a</span>ckground-color: #d<span style = 'background-color: #dae8f4'>a</span>e8f4'>m<span style = 'background-color: #dae8f4'>a</span>ny</sp<span style = 'background-color: #dae8f4'>a</span>n> 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.
Thanks Wave Yours suggestion matters for me i have planed to take lesser calorie food for 1 week and then will try to take f<span style = 'background-color: #dae8f4'>a</span>sting <span style = 'background-color: #dae8f4'>test</span> again
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.
On my Lab slip for thyroid <span style = 'background-color: #dae8f4'>test</span> my doctor puts no f<span style = 'background-color: #dae8f4'>a</span>sting. I do anyway because I have the <span style = 'background-color: #dae8f4'>test</span> 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.
and if i dont go and i over eat, i will get really sick basically, i'll over eat then feel nausea for <sp<span style = 'background-color: #dae8f4'>a</span>n style = 'b<span style = 'background-color: #dae8f4'>a</span>ckground-color: #d<span style = 'background-color: #dae8f4'>a</span>e8f4'>hours</sp<span style = 'background-color: #dae8f4'>a</span>n> and <sp<span style = 'background-color: #dae8f4'>a</span>n style = 'b<span style = 'background-color: #dae8f4'>a</span>ckground-color: #d<span style = 'background-color: #dae8f4'>a</span>e8f4'>hours</sp<span style = 'background-color: #dae8f4'>a</span>n>, when i finally do have the urge to throw up, its dry heaving an style = 'background-color: #dae8f4'>hoursan> 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.
Sorry about the bad glucose example…I was referring to fasting for an entire day (24 <sp<span style = 'background-color: #dae8f4'>a</span>n style = 'b<span style = 'background-color: #dae8f4'>a</span>ckground-color: #d<span style = 'background-color: #dae8f4'>a</span>e8f4'>hours</sp<span style = 'background-color: #dae8f4'>a</span>n>) before the draw (similar to d/cing your meds for 24 <sp<span style = 'background-color: #dae8f4'>a</span>n style = 'b<span style = 'background-color: #dae8f4'>a</span>ckground-color: #d<span style = 'background-color: #dae8f4'>a</span>e8f4'>hours</sp<span style = 'background-color: #dae8f4'>a</span>n> before). If f<span style = 'background-color: #dae8f4'>a</span>sting 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.
Hi cat Did your Doctor or your diabetic educator give you instructions for testing? Often the minimum is to <span style = 'background-color: #dae8f4'>test</span> your f<span style = 'background-color: #dae8f4'>a</span>sting <span style = 'background-color: #dae8f4'>blood</span> sugar when you first get up and then test two an style = 'background-color: #dae8f4'>hoursan> after breakfast. Then write down these numbers so your Doctor can see an style = 'background-color: #dae8f4'>howan> 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.
I just got back from seeing the doctor and I had him do some <span style = 'background-color: #dae8f4'>blood</span> work on me. He said everything in my <span style = 'background-color: #dae8f4'>blood</span> 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.
May I presume this is a f<span style = 'background-color: #dae8f4'>a</span>sting result? The Hba1c is slightly high, but the f<span style = 'background-color: #dae8f4'>a</span>sting <span style = 'background-color: #dae8f4'>blood</span> 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.
I have just starting testing my <span style = 'background-color: #dae8f4'>blood</span> glucose Do I need to <span style = 'background-color: #dae8f4'>test</span> every day or weekly ?
Thank you for this very informative answer to my question, which was is there something new about fasting or non-fasting cholesterol tests. The conflict was between what my cardiologist stated and what the internist was stating. apparently there is some validity to having the non-fasting test and all of this confusion could have been avoided if he would just have taken a moment and said he was trying something new.
I had the two hour test and you fast for 10 <sp<span style = 'background-color: #dae8f4'>a</span>n style = 'b<span style = 'background-color: #dae8f4'>a</span>ckground-color: #d<span style = 'background-color: #dae8f4'>a</span>e8f4'>hours</sp<span style = 'background-color: #dae8f4'>a</span>n> the night before and then have the <span style = 'background-color: #dae8f4'>test</span> in the morning. They take your <span style = 'background-color: #dae8f4'>blood</span> right away and then you drink this awful sugar drink. Who knows what's in it..... then you get your blood taken after an hour and the following hour. at least that's an style = 'background-color: #dae8f4'>howan> it worked for me.
When I sat waiting for my angiogram I talked to <sp<span style = 'background-color: #dae8f4'>a</span>n style = 'b<span style = 'background-color: #dae8f4'>a</span>ckground-color: #d<span style = 'background-color: #dae8f4'>a</span>e8f4'>m<span style = 'background-color: #dae8f4'>a</span>ny</sp<span style = 'background-color: #dae8f4'>a</span>n> people who were on their second bypass, 4th stent, etc and were ill again. With the medication we have available that is unacceptable. all we ask is to have 80 years of good health without suffering from heart attacks and strokes which lower our quality of life considerably. I'm happy to hear your numbers are good!
So I got my glucose test next Friday and I have the fruit punch a.k.a the red drink an style = 'background-color: #dae8f4'>howan> an style = 'background-color: #dae8f4'>manyan> women got sick after drinking it?
Went back to doc, sent me immediately to hospital for Ultrasound, CT scan, EKG and <span style = 'background-color: #dae8f4'>blood</span> <span style = 'background-color: #dae8f4'>test</span>. They said no deep vein clots, said there may be nerve damage. Sent to neurologist, he thinks the same. Sending me for MRI thurs. The Red Cross has taken responsibility and is paying all out of pocket expenses, but what if I do have nerve damage from this, what am I supposed to do. I can’t sleep, drive comfortably, hurts just hanging my arm down by my side.
I am 15 weeks and I was 124 in f<span style = 'background-color: #dae8f4'>a</span>sting and 220 after food in my first <span style = 'background-color: #dae8f4'>test</span>. Dr. Had put me on diet for four days n now I am 108 in fasting and 126 after food. Dr. Had advised me to be on a diet . this time diet is a little bit relaxed.
