DETECTION AND PREVENTION OF CONTAMINATION BY INTRAVENOUS FLUIDS IN BLOOD SPECIMENS

Pdf Summary

The document discusses the issue of contamination of blood specimens by intravenous fluids during sample collection. It provides a case study where a sample collected from a patient receiving IV fluids resulted in highly elevated and depressed analyte levels. The document emphasizes the importance of proper procedures to prevent contamination, such as temporarily discontinuing IV infusions before collection and discarding the initial blood to minimize error risks. Detection of contamination can be done visually or through various laboratory tools, and proper training for healthcare personnel involved in specimen collection is crucial. The summary outlines the significance of addressing preanalytic errors to ensure accurate test results and enhance patient safety. Additionally, the document offers CMLE questions to reinforce key concepts discussed in the text.
