You are the most important member of your own health care team. Use the skills of the professional you have access to, but maintain an active, informed and intelligent role yourself. No one else can possibly care as much as you do. Don't misinterpret a result or over-rely on test results to diagnose a condition, illness or disease.
Sequence is important.
Don't skip a step. Note special precautions before testing, such as avoiding vigorous physical activity or precautions regarding specified foods and drugs. Repeat any test that is abnormal on first testing. When a test is timed, be precise. If possible, use a stopwatch or a watch with a second hand.
