Impact of serum-clot contact time on lactate dehydrogenase and inorganic phosphorus serum levels.

Objectives: The aim of this study is to determine the longest acceptable serum-clot contact time before centrifugation in lactate dehydrogenase and inorganic phosphorus analysis.

Materials And Methods: The LDH and inorganic phosphorus serum levels from 103 adults were analyzed at three different storage times. The three measures were done immediately (T0), after a 2-h serum-clot contact (T2) and after a 4-h serum-clot contact (T4).
