Shared Decisions About Medical Tests
Medical tests are important tools, but they have limits. Informed
consumers know medical tests have costs and risks as well as benefits.
Learn the facts
- What is the name of the test, and why do you
need it?
- If the test is positive, what will the doctor do
differently?
- What could happen if you don't have the test?
Consider the risks and benefits
- How accurate is the test? How often does it
indicate that a problem exists when there is none (false-positive
result)? How often does it say there is no problem when there is one
(false-negative result)?
- Is the test
painful? What can go wrong?
- How will you feel
afterward?
- Are there less risky alternatives?
Ask about costs
- How much does the test cost?
- Is
there a less expensive test that might give the same information?
If a test seems costly, risky, or not likely to change the
recommended treatment, ask your doctor if you can avoid it. Try to agree on the
best approach. No test can be done without your permission, and you have the
right to refuse a test.
Talk to your doctor
- What are your concerns about the
test?
- What do you expect the test to do for you? Are your
expectations realistic?
- What prescription and nonprescription
medicines are you taking?
- What other medical conditions do you
have?
- Do you prefer to have the test or not?
If you agree to a test, ask what you can do to reduce the chance of
errors. Should you restrict food, alcohol, exercise, or medicines before the
test? After the test, ask to review the results. Take notes for your home
records. If the results are unexpected and the error rate of the test is high,
consider redoing the test before basing further treatment on the
results.
