| Blood Sugar Interpretation |
Blood sugar concentration is the amount of glucose present in the blood of human being. The four tests help to determine the ability of the body to metabolise the blood sugar.
- FBS- Fasting Blood Sugar
- RBS- Random Blood Sugar
- PPBS- Post Prandial Blood Sugar
- GCT- Glucose Challenge Test
- GTT- Glucose Tolerance Test
- HbA1c- Glycosylated hemoglobin
Fasting Blood Sugar
Blood must be checked after 12 hours of fasting. Normal value is 60-110mg/dl.
Random Blood Sugar
Blood samples will be taken at any point of time irrespective of the consumption of food. Normal value is 60-130mg/dl.
Post Prandial Blood Sugar
Blood must be checked after 2 hours of eating.Normal value is 60-140mg/dl.
Glucose Challenge Test
It measures the blood glucose level 1 hour after the woman has drunken the 50 gm or 70 gm of oral glucose.It usually done to screen for the diabetes in pregnancy. Normal value is below 130mg/dl.
Glucose Tolerance Test
It is a 3 hour test, usually done if GCT value above 140mg/dl in pregnant woman. It consists of drinking 100 gm of oral glucose and taking blood samples at 1hr,2hrs and 3hrs intervals. Normal values will be
- Fasing -<95 mg/dl
- 1 hr -180 mg/dl
- 2 hrs -<155 mg/dl
- 3 hrs -<140 mg/dl
HbA1c- Glycosylated hemoglobin
Recommended HbA1c value for non diabetic patients will be less than 4.5-5%.It indicates that in every 100 blood cells, 4 to 5 cells have glucose attached to them. In diabetic patients, less than 6.5% will be the normal range.
