QUESTION: It used to be that my doctor merely had my finger stuck for tests. Now, more and more, the nurse is taking the blood from a vein in my arm.
I was wondering if there was any difference in the results of these tests, and if one method was better than the other?
ANSWER: There are many screening tests that only require a drop or two of blood from which quite accurate and useful results may be obtained.
They have the advantage of using the blood obtained in the quick and easy method afforded by a finger stick, and may also be quite economical.
Again many people prefer this method of obtaining the blood specimen to that of a needle in the vein.
Actually, with new, very sharp, disposable needles used but one time, neither method is very painful.
However more precise measurements may require more of a sample and so the vein is used to rapidly collect all that is necessary.
With new developments in medical technology, several different tests may be run on a single blood sample, offering you some economies, and providing the physician with answers to more than one question.
It is not a question of one method being better than the other, but which type of test is required for your medical care.
