1. Study Purpose

   The purpose of this study was to determine the effects of collecting blood into plain versus gel tubes on the measurement of iPTH in serum from patients with chronic renal failure. Serum was separated after 20 minutes at room temperature and frozen at -20 degrees C until analysis.

   Summary of Findings:

   Serum iPTH levels were 13% higher when blood was collected into plain serum tubes rather than gel serum tubes (p<0.01). The authors hypothesize the difference may be attributable to the clot activator, the gel barrier, or both.
