Test Panel: Blood Sugar, Fasting Blood Sugar, FBS, Fasting Blood Glucose, FBG, Fasting Plasma Glucose, FPG, Blood Glucose, Oral Glucose Tolerance Test, OGTT, GTT, Urine Glucose

Tests in Glucose Panel:

BSR, BSL, BSF, OGTT, GTT, GCT, Urine Sugar, HbA1c,

Why Get Tested:

This test is done to diagnose diabetes mellitus.
This test is also done to evaluate and monitoring of the patient with diabetes mellitus.

When to Get Tested:

Blood glucose: when you are older than 45 years or have risk factors for diabetes; when you have symptoms suggesting high or low blood glucose; during pregnancy; when you are diabetic, self-checks up to several times a day to monitor blood glucose levels

Sample Required:

This test can be done on Serum. The serum should be separated within 30 minutes of collection.
The serum can be stored at 25° C for 8 hours and 72 hours at 4 °C.
Oxalate blood can also be used. Preservative sodium fluoride may be added.
The plasma can be stored at 25 °C for 24 hours (when there is preservative sodium fluoride).

Normal Values:

Fasting Blood Sugar: 74 to 106 mg/dL (4.5 to 5.9 mmol/L)
Random Blood Sugar: 80 to 120 mg/dl (4.4 to 6.6 mmol/L).
