Common Questions and Answers about Blood glucose meters how it works

Avatar n tn A good way to see if yours is within normal variance is to bring along your meter when you go for a blood draw (from a vein). Within 5-10 minutes of them drawing blood, do your own blood test and save the results. Compare them with what the doc tells you your number was. Your result should be within 15% of the doc's result. What's important here is to know how you feel & how you function when your BG is at different numbers.
Avatar n tn I have read, however, that sites other than fingertips can be less accurate. As to how different the glucose reading would be, it probably depends on the meter and perhaps on the size of blood drop.
Avatar f tn Home glucose checking is designed to only give a ballpark snapshot of what our blood glucose is at that moment of time. Blood flow through the body is dynamic and the chemistry, including glucose, at any given point will very from one moment to the next. That said unless you took a blood sample and tested it many times (not taking a new sample for each test, thus a different blood chemistry) the variance in readings you recorded are normal.
Avatar f tn How accurate are glucose meters?. The other day, I did two measurements of sugar blood in a row, (same finger) seconds appart and the glucose meter showed a difference in the numbers.
Avatar m tn Before leaving her doctors office your mother should have gotten a wealth of printed information on how to control and manage her diabetes. A list of recommended home glucose test meters should have been part of that package.
Avatar f tn thanks for your concern, i will try to track the blood glucose of my husband how it rises and drop down, the il get back to you to give the details. more power!
Avatar f tn 225 was high so in morning i went to lab with gluco meter and they picked blood from vein and tested on gluco meter ist it was 103 and in lab 87.lab technician told me that go home eat drink tea with sugar and come back after two hours.i did it and went to lab and result was 80.i went to my doc who is not a specialist in diabetes said do hba1c and result was 5.5.he said moniter your bs for 2 3 days last night i checked after one and half hour after dinner and glucometer reading was 248.
Avatar f tn s interesting that you question the accuracy of your glucose meter for I was reading the September 2008 issues of Consumer Reports that rated both blood-pressure monitors and blood-glucose meters. Only one blood-glucose meter scored excellent overall and also scored the highest for consistency- the Johnson & Johnson Lifescan OneTouch Ultra Mini. The Ultra Mini was followed by Ascensia Contour, ReliOn Ultima (WalMart), and Accu-check Compact Plus.
Avatar f tn In your first thread I mentioned that the FDA set manufacturing guidelines for home glucose meters at ± [plus/minus] 20%. This means your 70 mg/dl reading could be 70 mg/dl or it could be as low as 56 mg/dl or as high as 84 mg/dl. Home meters give an approximation not a true reading of glucose levels. Since your 100 mg/dl reading two minutes later falls out of this range, the questions remaining are: 1. How old is your father's meter? 2. Do the test strips have an expiration date? 3.

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 My doctor ordered blood work, my glucose result was 103. Doc wanted to put me on a Diabetic pill. I told him No, I would watch what I eat and we'd go from there. I used to junk out bad at night; candy, chips, drink regular cokes, ect... Now I drink Diet Coke and I don't eat anywhere near like I used to. I'm probably 10 pounds overweight. I have a physical job. I'm in good health, I have high blood pressure that is controled by meds. I bought a AccuCheck Active tester.
Avatar n tn t tell a doctor what is going with your glucose levels at all times of the day. Home glucose meters are good to see how well one is managing their glucose levels. Having scaled results (high to low, or normal to near high or above) calls for an A1c test to see the entire picture. An A1c test measures your glucose going back three months. Why three months? On the average, new red blood cells live three months before dieing off and getting turned into Bilirubin.
Avatar n tn s the HIGHEST it could have had, it probably had less) and it would take at least 15 minutes for it to ever hit your blood stream. The blood sugar difference you saw is not very likely to have had anything to do with the gum.
Avatar n tn hi. i have just come back from my duke of Edinburgh gold expedition ( 4 days of hard core walking up mountains!) and i am honestly quite scared. I've been fainting A LOT recently, and getting headaches too. i've had hypoglycemia for a few years now, but i know how to manage it, and know what to do when my hands start shaking - and it's never been worse than fainting and feeling awful.
Avatar m tn You need to eat more. You should test your glucose two hours after you eat. Your fasting blood sugar should 80 to 110. Your blood sugar dropped 6 points is only because it didn't have time to react. Since you didn't wait two hours.
Avatar m tn Whoa Nelly. My advice is to start with square one and learn about what diabetes is and how to control,it. A book "Idiot's Guide to Diabetes" is out there, and although not the best book, nor the most accurate, it is understandable. To optimally control diabetes you need to have an accurate idea of the effect of food and exercise on your blood sugar levels. The hba1c by itself is totally inadequate for this purpose.
Avatar m tn And, 2-3 hours after eating [postprandial] when glucose [blood sugar] is at its highest point. The first is to get a baseline to work off, the second to see what foods you consumed does to your glucose level and what you can and should not eat. "where do I need to be using his # " Huh? Are you asking what numbers are considered normal ranges? These are: prandial = 70-99 mg/dl or 3.8-5.5 mmol/l postprandial = <180 mg/dl in most cases <10.
Avatar f tn Yes, there is a difference. The glucose meter measures blood sugar at that exact moment. The A1C, on the other hand, gives an average of blood sugars for about 2-3 months period. The A1C therefore, gives a lot more significant information but it can also be misleading. For example of someone has a lot of highs, but also a lot of lows, it might average out and look like the person is maintaining a good blood glucose level when they are, in fact, swinging wildly.
Avatar m tn d guess, but one thing I did a few months ago was test my fasting glucose maybe an hour before going to have blood drawn for professional lab testing for complete profile. I was getting mid 80s at home, but my glucose came back 106 from the lab.
Avatar m tn s glucose at the office or hospital, are they using the hand held meters or taking blood draws? First, if they are using hand held meters there usually is a variance in readings from meter to meter--if the readings are drastically different then there could be something wrong with the meter. If this is the case, ask her doctor for a new meter---meter companies are always giving meters to doctor to hand out for free.
