Diabetes - To diagnose Type 1 diabetes or Type 2 diabetes, endocrinologists may perform the following blood tests:
- Glycated hemoglobin (Ac1) test – this blood test measures the sugar level in the blood. A high blood glucose level after two tests indicts the presence of diabetes. This blood test cannot be performed during pregnancy.
- Random blood sugar test – this blood test measures the sugar level in the blood. Fasting is not required to take this blood test. If other signs of diabetes are present, a high blood glucose level indicates diabetes.
- Fasting blood sugar test – this blood test measures the sugar level in the blood after fasting. If other signs of diabetes are present and this blood tests results in high sugar on two separate tests, then diabetes is diagnosed.
Thyroid disorders - To diagnose thyroid disorders, blood samples are taken to measure the thyroid stimulating hormone levels in the blood. Too much hormone indicates hyperthyroidism, or overactive thyroid, while not enough hormone indicates hypothyroidism, or underactive thyroid.
