    • Purpose: Measures your blood sugar after an overnight fast (typically 8 hours).
    • Procedure: A blood sample is taken in the morning after you haven't eaten.
    • Interpretation:

    | Result | Category | Implication | |----------------|------------------------|----------------------------------------------| | Less than 100 mg/dL | Normal | Indicates healthy blood sugar levels. | | 100-125 mg/dL | Prediabetes | Indicates increased risk of developing diabetes. | | 126 mg/dL or higher | Diabetes | Suggests you may have diabetes. Further testing is required to confirm. |

  2. Random Blood Sugar (RBS) Test:

    • Purpose: Measures blood sugar at any time of day, without regard to when you last ate.
    • Procedure: A blood sample is taken at a random time.
    • Interpretation:

    | Result | Category | Implication | |------------------|---------------|---------------------------------------------------| | 200 mg/dL or higher | Possible Diabetes | Suggests you may have diabetes, especially if accompanied by symptoms like excessive thirst, frequent urination, and unexplained weight loss. Requires further testing. |

  3. Oral Glucose Tolerance Test (OGTT):

    • Purpose: Measures how your body processes glucose after drinking a sugary solution.
    • Procedure: You fast overnight, then drink a special glucose drink. Blood sugar is tested periodically for the next two hours.
    • Interpretation:

    | Time | Result (mg/dL) | Category | Implication | |---------|----------------|---------------|---------------------------------------------------------| | Fasting | Less than 100 | Normal | Healthy fasting glucose level. | | 2 hours | Less than 140 | Normal | Healthy glucose processing. | | Fasting | 100-125 | Prediabetes | Elevated fasting glucose level, risk of diabetes. | | 2 hours | 140-199 | Prediabetes | Impaired glucose tolerance, high risk of developing diabetes. | | Fasting | 126 or higher | Diabetes | Possible diabetes, requires further testing. | | 2 hours | 200 or higher | Diabetes | Suggests diabetes, further confirmation needed. |

  4. A1C (Glycated Hemoglobin) Test:

    • Purpose: Measures your average blood sugar levels over the past 2-3 months.
    • Procedure: A blood sample is taken and analyzed to see what percentage of your red blood cells have glucose attached to them.
    • Interpretation:

    | Result | Category | Implication | |----------------|------------------------|-----------------------------------------------------------------------------------| | Less than 5.7% | Normal | Indicates good blood sugar control over the past 2-3 months. | | 5.7-6.4% | Prediabetes | Indicates higher than normal blood sugar levels, increased risk of developing diabetes. | | 6.5% or higher | Diabetes | Suggests diabetes.
