When your doctor orders blood tests during a routine check-up, the goal is to learn how well your body is working and to diagnose diseases such as diabetes or heart disease that might not have obvious symptoms. A blood test is like a gauge, revealing measures of disease inside your body.
You might have any number of different blood tests during your check-up. Four blood tests in particular are important to determine the state of your health. If your doctor hasn't recommended one or more of these blood tests, ask whether you need to have them done.
1] Blood Sugar Test
2] Lipid Panel
3] Thyroid-stimulating hormone (TSH) and T4 test
4] Vitamin D (25 hydroxyvitamin D) test
