Introduction
Diabetes, a chronic metabolic disorder, affects millions of people worldwide. Early detection and accurate diagnosis are crucial for effective management. Several clinical tests are available to diagnose diabetes, each offering valuable insights into a patient's condition.

1. Fasting Plasma Glucose (FPG) Test
The FPG test measures blood sugar levels after an overnight fast. A reading of 126 milligrams per deciliter (mg/dL) or higher typically indicates diabetes.
2. Oral Glucose Tolerance Test (OGTT)
The OGTT involves fasting and then consuming a glucose-rich drink. Blood sugar levels are monitored at intervals. A two-hour post-drink reading of 200 mg/dL or above suggests diabetes.
3. Hemoglobin A1c Test (HbA1c)
The HbA1c test provides a long-term average of blood sugar levels. An HbA1c level of 6.5% or higher usually indicates diabetes.
4. Random Blood Sugar Test
This test measures blood sugar at any time, regardless of fasting. A reading of 200 mg/dL or more, along with diabetes symptoms, may indicate the condition.
5. Glycated Albumin Test
This test measures the percentage of glycated albumin in the blood. It offers a shorter-term view of blood sugar control.
6. Continuous Glucose Monitoring (CGM)
CGM involves wearing a sensor under the skin to monitor blood sugar levels continuously. It provides valuable data for diabetes management.
Conclusion
The choice of diabetes diagnostic tests depends on various factors, including the patient's symptoms and medical history. Early diagnosis through these clinical tests is essential for timely intervention, enabling individuals to better manage their diabetes and lead healthier lives. Regular monitoring and consultation with healthcare professionals are key to successful diabetes management.
