- Answers About the Value of Blood Tests
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: I know that blood tests form an important tool for doctors to use
- to help make diagnoses. Still it is hard to understand why at each visit,
- there are either new tests to take, or old tests to repeat. With each test
- costing more than I make in an hour, I need some answers about their value.
- Please explain.
-

- ANSWER: There are several good reasons for a doctor to take blood samples for
- testing, even when they seem to come too frequently and too often. In the
- initial stages of evaluation, when the diagnosis is still uncertain, it may
- take several tests before one shows any evidence of a disease. When results
- are normal, a test is classified as "negative", and while negatives are signs
- that little is wrong, they don't help too much in establishing just what is
- wrong. There are many diagnostic blood tests available today, and it would be
- foolish to test for everything at once, so most physicians proceed in a manner
- that will provide the quickest answers at the least cost to the patient. They
- test first for the most probable cause, and then proceed to lesser diseases
- that can provoke the symptoms and complaints you presented when you arrived at
- the office. Once the diagnosis is obtained, treatment is started, and the
- effects of the treatment can be followed by testing the blood regularly. The
- first abnormal results (they are called "positive") soon begin to return to
- normal as the treatment takes effect. This is particularly important in
- diseases such as diabetes, anemia and kidney ailments. I don't know the
- reason for each test in your case, but it is most important that you find out
- the purpose for these examinations from your physician, and become well
- informed about your condition, its causes and its treatment, and satisfy
- yourself that the tests are truly needed. You may then learn that your money
- was well spent.
