I'm a little confused about the different types of blood tests that are available. Which ones are most useful?

The most useful type of blood test is one that can accurately measure your cholesterol levels, such as a lipid panel or total cholesterol test. These tests help to determine your risk for heart disease and stroke, which is why it's important to get them done regularly. Other useful tests include those for glucose, hemoglobin A1C (HbA1c), thyroid hormones, vitamin D, and iron levels.
