Blood tests are among the most common medical tests. They help check your general health, diagnose conditions and monitor treatment. Tests you may hear about include:
- Complete blood count (CBC): red cells, white cells and platelets, which can point to anemia or infection.
- Metabolic panel: kidney function, electrolytes and blood sugar.
- Lipid panel: cholesterol and triglycerides.
- HbA1c: your average blood sugar over the past two to three months.
- Thyroid tests: how well your thyroid gland is working.
Some tests require fasting, so follow the instructions you are given. Normal ranges vary between laboratories, and a result slightly outside the range is not always a problem. Your doctor will interpret results alongside your symptoms and history, so ask them to explain anything you are unsure about.
