Which is more accurate fasting glucose or HbA1c?
However, in an epidemiological study, it has been concluded that FBS is more accurate than HbA1c. The best cutoff point for defining high HbA1c is another important issue. The Diabetes Control and Complications Trial suggested the value of 6% as HbA1c cut point.
What is HbA1c normal range?
A normal A1C level is below 5.7%, a level of 5.7% to 6.4% indicates prediabetes, and a level of 6.5% or more indicates diabetes.
What is difference between HbA1c and average blood glucose?
However, HbA1c is a "weighted" average of blood glucose levels during the preceding 120 days, meaning that glucose levels in the preceding 30 days contribute substantially more to the level of HbA1c than do glucose levels 90-120 days earlier.
Is blood sugar in plasma?
Therefore, glucose concentrations in plasma are approximately 11% higher than whole blood if the hematocrit is normal.
Which blood sugar test is more accurate?

What Does Mean Plasma Glucose Of 119 Mean?
What does mean plasma glucose of 119 mean? I have a mean plasma glucose of 119. Another website says this means that I'm prediabetic. My doctor says it's perfectly normal. This was taken after a 12 hour fast. My glucose was 86. You marked this post as helpful! I changed my mind The normal blood sugar after 12 hours of fasting should be below 100 mg/dl (As per the ADA recommendations). In your case this seems to be 86, and this is within the normal level. The Random blood sugar (RBS) measures blood glucose regardless of when you last ate. The normal range should be between 70 - 125 mg /dl. Prediabetes (or Impaired blood glucose) is considered when the fasting blood sugar (FBS) is in the range of 100 - 125 mg/dl. Diabetes mellitus is considered when the FBS is above 126 mg/dl. The best way to confirm the glucose control in the body is via the HBA1C test. A normal non-diabetic HbA1C is 3.5 - 5.5 %. In diabetes about 6.5% is good. Above 7.0 diabetes is considered as uncontrolled. You might consult with your doctor for proper counselling and advice. Continue reading >>

What is the normal blood glucose level?
Normal fasting blood glucose -- or blood sugar -- is between 70 and 100 milligrams per deciliter or mg/dL for people who do not have diabetes. The standard diagnosis of diabetes is made when two separate blood tests show that your fasting blood glucose level is greater than or equal to 126 mg/dL.
How long before a blood glucose test can you eat?
Before taking the blood glucose test, you will not be allowed to eat anything for at least eight hours.
What is the most common form of diabetes?
The most common form of diabetes mellitus is type 2 diabetes which is a worldwide chronic disease. The aim of this study was to investigate the accuracy of fasting plasma glucose (FPG) and glycated hemoglobin (HbA1c) testing for the early detection of diabetes and to evaluate the correlation between FPG and HbA1c as a biomarker for diabetes in the general population in Hong Kong. This study also observed and assessed the risk of diabetes by comparing different genders and ages in Hong Kong. A retrospective study was undertaken and the data was collected in the database of a HOKLAS (The Hong Kong Laboratory Accreditation Scheme) clinical laboratory from 200 diabetic and non-diabetic patients (83 females and 117 males, age ranged from 20 to 90) who attended the laboratory during January 2016 to February 2016 for both FPG and HbA1c measurements. A significant correlation between HbA1c and FPG (r2 = 0.713, p < 0.05) was observed in this study. Moreover, patients detected as diabetes in age groups 45–64, 65–74 and ≥75 years old were 2.5, 3 and 6 times respectively higher than that of the diabetic individuals under 45 years old. In conclusion, FPG was significantly correlated with HbA1c and a significant increase in FPG and HbA1c in male was observed by comparing with female. Furthermore, the incidence rate of diabetes mellitus in male was 3 times higher than that in female in Hong Kong and it progressed with increasing age. Further longer term and large scale research in each age group is warranted. Fig. Continue reading >>
What is considered impaired fasting glucose?

RESEARCH DESIGN AND METHODS
The DCCT data set was provided by the National Institutes of Diabetes, Digestive, and Kidney Diseases of the National Institutes of Health and was prepared by the Data Coordinating Center at George Washington University.
RESULTS
The results of linear regression analysis are summarized in Fig. 1. The Pearson correlation coefficient ( r) was 0.82; change in MPG per increase of 1% HbA 1c was 1.98 mmol/l (35.6 mg/dl).
CONCLUSIONS
The increasing use of HbA 1c to monitor long-term glycemic control in diabetic patients is largely the result of data from the DCCT and the U.K. Prospective Diabetes Study showing that HbA 1c is strongly correlated with adverse outcome risks.
