A blood sugar test is a procedure that measures the amount of sugar, or glucose, in your blood. Your doctor may order this test to help diagnose diabetes.
Also Known as: Fasting Blood Sugar, FBS, Fasting Blood Glucose, Blood Sugar Fasting, BSF, BSL
| Also Known as | BSR, BSF, BSL, Blood Sugar Random, Blood Glucose Random, RBS, Random Glucose, Random Sugar |
| Test Purpose | Describes how blood glucose tests are used, such as to screen for and diagnose prediabetes and diabetes, to detect hyperglycemia or hypoglycemia, and to monitor blood glucose levels over time when treating diabetes |
| Test Preparations | No Need any Preparation |

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).
