How many hours count as fasting for testing blood sugar? Are my numbers abnormal?
Eight hours is long enough for a fast since non-diabetics typically return to pre-meal levels within 2-4 hours after eating. Ideally you would have been below 99 mg/dL at that point. The problem with testing at home, of course, is the possibility of meter and user error, as well as the margin of error. The 106 mg/dL is noteworthy because technically it's in pre-diabetic fasting range (100-125 mg/dL), but until you see a doctor, nothing is definitive. Your two-hour post-meal blood sugar was completely normal and even your three-hour was normal, but it's unusual to be higher at three hours than two hours. Usually, non-diabetics have a fairly predictable blood sugar pattern after eating where blood sugar is highest at 45 minutes to 1 hour or so. By two hours, blood sugar starts dropping down closer to pre-meal levels, sometimes at pre-meal levels. By three hours, non-diabetics will be lower than they were at two hours. Again, the meter could be wrong, the margin of error could be making it appear as though you were higher than you were or perhaps your hands weren't clean. Make an appointment with your doctor and ask for a fasting blood sugar test and an HbA1c, a three-month average of blood sugar levels. Good luck to you.
Eating before a fasting blood test!!?
I have read on other sites that for a basic Cholesterol test it's not really necessary to fast at all. At first I thought that was a little strange but I notices several sites saying the same thing. Then on my last Cholesterol test When I got up in the morning I forgot I had the test in a couple hours and had two poptarts and a cup of coffee with creamer in it. I stressed the whole week waiting for the results and what I was going to tell my Doctor. When I got to my Dr's appointment I was informed all of my numbers were perfect. Cholesterol was at 133 and my other numbers were all in the ideal range. So maybe there is something to it. Still, all the same I would still probably fast at least 8 hours prior to my next one only because I have been doing that for years.

Does what you eat 24 - 72 hours prior to a fasting blood test affect the results if it is different from your normal diet?
I've seen the results changed from eating a lot of high fat foods for 3 days before his test.The Dave Feldman Protocol showed proof this could be done by reducing his cholesterol lipid test, just from eating very high fats for 3 days. He ate well over 4000 ketogenic calories each day, avoiding coffee, coconut and/or MCT oils for his well documented, self experiment. Others have since done the same thing with the same kind of lower results.
Would eating a small pizza before fasting for a blood exam change drastically my results?
What I would tell my fellow Navy buddies who forgot to fast for their yearly physical was you are taking a chance of your blood sugar being a little high and your lipids being off … if you are willing to take that chance of having that in your record, then I will draw you. Most of them took the chance because they were 20 somethings in perfect physical condition.Pizza has fats and carbs … if you are older, “Hitting the marks of normality becomes a challenge” … EVEN IF YOU HAVE FASTED FOR 8–12 hours. If your doctor wants to do further tests on you … CONFESS. Your results (glucose and lipids/ cholesterol) are biased and should be repeated on a FASTING SPECIMEN.OK … I think I misread the question. Eating BEFORE YOU START YOUR FAST is still considered a FASTING BLOOD SPECIMEN. The minimum time is 8 hours. YOU SHOULD EAT NORMALLY and if that includes pizza, then that is your pattern and we want to see what your values are under the conditions you live in. Before doctors had A1C’s to view a diabetic’s eating patterns, they were bamboozled by diabetics like my Aunt Edna who would fast for 2–4 days before her blood draw to gain a pat on the head from her doctor on how well managed she was on her blood sugars. While she could fool the doctor with a snapshot GLUCOSE level, the A1C is a long view of your glucose range … you can’t fast for 24–48 hours and expect it to change for praise from your doctor.
Can you drink (soda) when your have a fasting blood test?
For fasting water is okay. Have nothing with calories within 12 hours prior to the blood draw. After blood is drawn, it is okay to eat and drink as soon as you can.
Can I drink Gatorade before a fasting blood test?
Can I drink Gatorade before a fasting blood test?Not if you want accurate results. Anything we drink within eight or nine hours of a blood draw for labs needs to have no calories, no carbohydrates and no electrolytes. Some sweeteners contain carbs, so either avoid all sweeteners or investigate/ask about the one(s) you want to use.Here are a few things a person can drink before a routine fasting blood test:waterflavoured water with no sugar (carbonated water is ok if no electrolytes)black coffee with no milk, cream or sugartea with no milk, cream or sugardiet soda (ask doctor)That’s all I can think of right now, but you get the idea.It’s pretty important. When I forgot and had a snack at 3:00 am, my doctor had me reschedule my blood draw rather than chance inaccurate results. Another time I ate about 3:00 am and forgot to tell him, my blood glucose was 111 mg/dl and it was interpreted as pre-diabetes. Now, I think that’s a bit much* but just saying that a snack or drink can skew your results.*seems pretty normal to me
How many hours do I have to fast before a cholesterol blood test?
Three different references, three different answers. I guess the best answer is to ask the lab faculty before your test..... A fasting blood test is a blood sample taken from a person who has not eaten for at least 8 hours. Usually, the blood sample is taken early in the morning. Examples of blood tests that may be done after a period of fasting include fasting blood sugar (fasting plasma glucose) test and lipid profile (cholesterol and triglycerides). http://www.webmd.com/hw/health_guide_ato... Patients who are scheduled for a lipid profile test should fast (except for water) for 12-14 hours before the blood sample is drawn. If the patient's cholesterol is to be fractionated, he or she also should avoid alcohol for 24 hours before the test. http://www.healthatoz.com/healthatoz/Ato... To get accurate results, you should fast for 9 to 12 hours before the test. The health care provider may advise you to stop taking drugs that can affect the test. (See "Special considerations.") You may drink water during the fast, but other beverages such as coffee, tea, or soda may affect results. http://www.pennhealth.com/ency/article/0...
Can you eat before a blood test?

You may also be told not to smoke before your test.Common fasting blood testsExamples of blood tests that require you to fast include:a fasting blood glucose test (used to test for diabetes) – you fast for 8 to 10 hours before the testan iron blood test (used to diagnose conditions such as iron deficiency anaemia) – you fast for 12 hours before the test
What happens if you eat before fasting glucose test?
If just a fasting test you can change the test name to a random glucose test. Here are the numbers::What Are Normal Blood Glucose And Blood Sugar Levels There are various methods to determine blood glucose level. Some tests give you accurate diagnosis of diabetes or pre-diabetes, while others will tell you how well you are managing your diabetes. Fasting Blood Sugar Test: Measures the blood sugar level after 8 hours fast or overnight. Normal fasting blood glucose level is less than 100mg/dl. If your fasting blood glucose level is from 100mg/dl to 125mg/dl then you will have impaired blood glucose level also known as Pre-Diabetes. If your blood glucose level is above 125mg/dl then your doctor will diagnose as a patient of diabetes. To confirm the diagnosis, your doctor may repeat the fasting blood glucose test on any other day. If you have blood glucose level of 126mg/dl or higher in two consecutive tests, then you may have diabetes. If you have blood glucose level greater than 200mg/dl and you have symptoms of diabetes like increased thirst or hunger, frequent urination, weight loss, blurred vision etc, then you may be diagnosed with diabetes mellitus without confirming it with second test. Post-Meal Blood Sugar (Postprandial) Independent of what they eat, the blood sugar of a truly normal person is: Under 120 mg/dl (6.6 mmol/L) one or two hours after a meal. Most normal people are under 100 mg/dl (5.5 mmol/L) two hours after eating You just said a fasting test not a glucose tolerance test?Yes! >
