Blast from the Past-using PTH to Differentiate Acute versus Chronic Kidney Disease

Chase Cavayero,Sunny M Kar,Ani

Abstract

In these times of limited financial and human resources, physicians must be cognizant of the rising costs of healthcare. Expensive imaging studies should be reserved for conditions that are particularly challenging to diagnose using traditional laboratory tests. Consequently, we must revisit the use of alternative simple, inexpensive and readily available laboratory tests to help differentiate medical conditions. Therefore, we would like to revisit the use of intact PTH as a discriminatory lab value in evaluating chronic vs. acute kidney injury.
