Medical tests have become a household name as a guide or reference for remedial treatment measures. Is there a standard that gauges the accuracy level of these medical tests.
Researchers use a Gold standard, a bench mark test against which is compared the medical test in question, to gauge the preciseness of the result or measure the deviation. Generally Gold standard benchmark tests consume time and are often an ex pensive proposition.
Anne Rutjes and colleagues studied 487 primary studies of test evaluations to check out if published results were precise. Much to their surprise, they discovered that only one among the lot they studied seemed to match the desired level of accuracy.
The results of this analysis showed that the test would be really accurate when it concerned patients with severe disease, while the accuracy level dropped when the test involved checking for mild or early stages of a disease.
