Glucose Fasting level ( With details )

Rate: Rs. 50

Sample

This test can be done on Serum and oxalated blood.

Stability of sample

One ml blood in anticoagulant will be stable for 3 hours with flouride or oxalate.and in plasma at 2 to 8 c for 48 hours.

Mostlty serum is used which is stable for 8 hours at 25C and 72 hours at 4 C.

•For fasting sample ,fast of 6-8 hours is required.

Important facts

•Concentration of glucose is higher inarterial blood than venous.

•When this is around 126 mg/dl then try to esimate glucose level after oral 75 grams of glucose and check one hour and two hour samples.This oral glucose test will pick up Impaired Glucose Tolerance cases where you can prevent the development of Diabetes Mellitis.

•When the fasting level is between 100 to 126 mg/dl is called fasting hyperglycemia.

Now latest classification criteria is fasting glucose level 126 mg/dl or above should be labelled as D.Mellitis (when found two times).

Normal

It’s level is less than 100mg/dl.
