Lab test profiles are designed to screen for disease in as many systems of the body as possible. Early detection of disease conditions will give you the opportunity of disease prevention. Curative treatment can be instituted and many diseases can be treated early and complications can be prevented. From these screening tests we will determine if further tests are necessary and so saving you the costs of unnecessary investigations.
Because reference ranges (except for some lipid studies) are typically defined as the range of values of the median 95% of the healthy population, it is unlikely that a given specimen, even from a healthy patient, will show “normal” values for all the tests in a lengthy profile. Therefore, caution should be exercised to prevent overreaction to miscellaneous, mild abnormalities without clinical correlate.
