Study Purpose
The purpose of this study was to determine the effects of PTS transport, tube fill volume, anticoagulation with heparin, and clotting prior to transport on clinical chemistry analytes in blood. Blood was obtained from patients in the emergency room or intensive care unit and transported immediately or allowed to clot for 15 min prior to transport. For blood gas analysis the specimens were wrapped in a cold pack prior to immediate transport.
Summary of Findings:
CO2 and Cl- were slightly increased in specimens transported by PTS rather than hand-delivered. Transport method did not affect K+, hemoglobin, or LDH when collection tubes were half-filled or when they contained heparin, but LDH was increased in clotted blood that was sent by PTS rather than hand-delivered. For unclotted specimens collected with no anticoagulant, glucose, urea, sodium, K+, LDH, hemoglobin, pH, partial pressure oxygen (PO2), and partial pressure carbon dioxide (PCO2) were unaffected by transport method.
