Data on the internal consistency of fasting blood glucose (FBG) and 2 hrs-oral glucose tolerance test (OGTT) are scarce despite of its importance both for research and treatment purposes. FBG and OGTT were performed on two consecutive days among the 218 (107 men and 111 women) newly diagnosed type 2 diabetes patients at BIRDEM (a diabetic hospital), Dhaka Bangladesh. Further studies are needed to investigate the observed difference in FBG measures with specific attention to BMI and the fasting state. Different diagnostic criteria have been established to reduce the risks for the development of complications among the diabetic patients [1,4]. The ADA published revised criteria for the diagnosis of diabetes that includes a FPG value, with a confirmatory test on a subsequent day [6]. All people with type 2 diabetes who were diagnosed within 4 weeks prior to the scrutiny attending FBG test at outdoor facility of Bangladesh Institute of Research on Diabetes, Endocrinology and Metabolism (BIRDEM) hospital, Dhaka, Bangladesh were requested to participate in the study during the month of November, 2003. 1st day data collection- (FBG1 and OGTT1) – Screening subjects attending BIRDEM hospital for confirmatory test were informed about the procedures of the test previously at the time of collection screening test result. 2nd day data collection- (FBG2 and OGTT2) - FBG and OGTT tests were repeated on all the subjects on the next day by ensuing the same procedure. Consistency of the diagnostic procedures FBG or OGTT for the diagnosis of diabetes mellitus appeared to be reasonably reliable on two consecutive days. Relatively stronger consistency over the repeated tests was observed among lower level of FBG values, while this was true for higher OGTT values. More investigations are needed to reduce the ambiguity of the test results by including some control subjects, preferably in the hospital and rather than fasting time to reduce the confusion, and to observe the creditability of the fasting state as assessed by interviews. We sincerely thank the team at BIRDEM hospital for their cooperation and the subjects for their participation.

Our free blood sugar chart (or blood glucose chart) lets you track your blood sugar levels throughout the day. Print this blood sugar log and attach it to your fridge or wherever you typically test your blood sugar. With this Blood Sugar Chart spreadsheet you can enter your blood sugar test results and see those results plotted on a graph along with your recommended upper and lower blood sugar levels. Remember to enter notes next to your entries regarding your diet and exercise so that you can see how they may be affecting your levels.
Tracking your blood sugar level (or blood glucose level) is highly recommended to give you power over your body and health.
Measuring your Blood Sugar Level: You can check your blood sugar level with a blood glucose meter at any time during the day, but generally people take them before meals and before they go to bed at night. Tracking Your Blood Sugar Level: After using the meter to find your blood sugar level, enter the date, time, level and any notes into the chart.
If you are on an exercise plan, ask your doctor for the best time to take your levels, to determine the affects your exercise plan is having.

Further, an interview with each subject was conducted and HbA1c, bio-physical and anthropometric examinations were performed.
The observed variation for FBG and OGTT should be considered during diagnosis of diabetes or control of the condition.
The most widely used diagnostic criteria for glucose intolerance was recommended by the World Health Organization (WHO) based on fasting plasma glucose (FPG) value and glucose value measured 2 hrs after a standard 75-g glucose load (OGTT) [5]. In contrast to the recommendation of ADA, World Health Organization (WHO) recommends using the OGTT in clinical practice [5].
At that time participants were asked to undertake 12 hrs fast for confirmatory test, avoid any treatment for diabetes and physical activities during this one month. A fasting sample of venous blood was also collected for HbA1c measurement on the second day by HPLC (ion exchange high-performance liquid chromatography) using a Modular Diabetes Monitoring System (BioRad, Variant, USA) method. However, it was observed that PD was normally distributed and that a total of 95% of the FBG and OGTT values varied respectively within approximately ± 25 % and ± 24% on a day to day basis.

I will be getting into specifics in this post here and breaking down the  individual tubes, additives and laboratory uses that each tube serves for. It consists of evacuated tubes of various sizes, with color coded tops indicating tube contents.
It's always good to know all of the tubes though in case you ever encounter them at smaller labs or clinics.
Thanks for hanging in there even though I'm probably sure most of the time you said to yourself "What in the *u*k is that?!!" I loved learning about all of the tests and things that you can learn just from somebodies blood *salivates* it's great. It also allows you to enter in normal blood sugar levels, both high and low, so you can see how well you are staying within your healthy range. This printable blood sugar log allows you to write down your results no matter where you are. For the A1C level chart, you can enter the level that your doctor recommends you stay close to. Tracking your blood sugar level along with your diet and exercise lets you see how to use diet and exercise to keep you at the right levels and stay healthy.
Notes could include what food you ate, what exercises you did, or anything else that you think influences your levels. I had my first diabetes hemoglobin A1c test only many weeks later because my doctor failed to notify me about my high fasting blood glucose levels. A 17-gauge Luer-lock venflon was inserted in to both anticubital fossa and sample was taken for HbA1c.
Statistical comparisons among sex, BMI, SBP and DBP were made by one sample t- test for continuous variables and chi-square tests for group comparisons.

The inconsistency of the test results was largely influenced by female subjects following FBG procedure. HbA1c appeared to have improved associations with FBG measures contrasting against OGTT values. The upper limit of blood glucose measurement by HemoCue Blood-glucose analyzer and sample size may also be a concern for further investigation. Next to each entry, you can enter notes about your diet and exercise, to see how they affect your levels. You can also show your healthcare provider your results to help them provide you with a better care plan. Because the average life of a red blood cell is about 4 months, this test will give you a good idea of how you've been doing for the past 2 to 3 months.
That is one of the reasons why I fired that doctor and got a new doctor for my diabetes management.
Moreover, the DECODE study found that almost 30% of all patients with diabetes (based on fasting or 2hrs - PG following OGTT or both) would remain undetected [7].
At the end of 2hrs blood glucose test, all subjects were interviewed to collect information regarding socio-economic, family history, treatment history and smoking habit etc. Anthropometrical data and blood pressure were measured in the same examination room to avoid any influence of physical activity between 2 hrs time of glucose drink and OGTT2. Moreover, both FBG and OGTT values appeared to have no significant deviation from normality as assessed by the PD.
Either setting will likely have implications in the epidemiology, treatment and control of the state of diabetes. You can also keep track of your A1C levels (also referred to as hemoglobin HbA1c levels), which you get tested by your doctor. Do not tolerate a lack of attention to your case or incompetence, as it is your life in the balance not your doctor's! This low agreement may raise concern for identification and treatment of people with diabetes. Moreover, the increased variability was also stratified by hypertension, which may raise attention for diagnosis of hypertensive subjects. It was also recommended by ADA that the internal stability of the diagnostic procedures should be carefully considered when monitoring glycemic control for people with diabetes [10,13].
Liner regression analysis was carried out to describe the relation between FBG, OGTT and HbA1c with PDs and averaged values of them. Therefore, elevated variability of the test results among women and hypertensive subjects by FBG procedure deserves attention for future studies with a focus on obese status. This may have been true for the newly diagnosed cases as was observed in other studies [18]. Data on the internal consistency of these two procedures is scarce especially from ethnic groups representing the highest increase of incidence in type 2 diabetes. Scattered diagrams are also presented to indicate the correlation and inter-relationship of those values. Therefore the purpose of the study was to assess the day to day variability of FBG and OGTT in people with newly diagnosed type 2 diabetes in Bangladesh. In addition, both the diagnostic procedures were examined against glycosylated hemoglobin A1c in order to observe the strength of FBG and OGTT procedures.
