Effect of Tourniquet Application on Serum Calcium Determination
Sabitha S, Silpa L
Abstract: The preanalytical process of sample collection establishes the validity of therapeutic interventions and the precision of laboratory results. Erroneous laboratory results can result from an inaccurate sample collection process, which can lead to an incorrect treatment plan. The most often used sample in laboratory analysis is blood, which is drawn using a tourniquet.A tourniquet is typically used during venous blood sampling procedures to assist in locating peripheral veins in order to facilitate a successful and secure venipuncture. However, one frequent cause of preanalytical errors has been the kind and timing of tourniquet application prior to blood collection. Applying a tourniquet prior to sampling may have an impact on certain lab parameters.As a result of the extended venous stasis caused by the tourniquet application during venipuncture, various biochemical analyte results may differ.The measurement of potassium and calcium may be impacted by prolonged tourniquet use, which may cause local hypoxia and acidosis.A localized acidotic environment causes the cells to release calcium, which raises the calcium content. Minerals that are most prevalent in the body are calcium and . In physiology, it plays a variety of vital functions. So inaccuracies in the result potentially affect patient safety.The purpose of this article is to provide an overview of how various tourniquet application times affect the overall concentration of calcium in the blood in healthy individuals.
