Klinik Kimya Laboratuvarında Acil Durum Testlerinde Plazma Tüpü Kullanımı

Abstract

The major considerations for the STAT testing performed in laboratories are to obtain a fast and accurate test result. Increasing number of instruments and methods have been developed for making it possible to perform the STAT testing on plasma rather than serum. The aim of this study is to compare the STAT test results of the serum and plasma sample tubes. Venous blood samples of 78 patients were collected into BD Vacutainer®SST™II Advance serum gel and Vacutainer®Barricor™ plasma tube. The sampling orders of the tubes were switched during blood collection and loading the tubes into the instruments in order to ensure randomization. It was ensured the tubes were inverted, completely filled, and were allowed serum tubes to clot for a minimum of 30 minutes from the time of blood collection. It was determined that the chloride and sodium tests had a good concordance and the remaining tests had a strong level of concordance.
