Importance of biological variation data of analytes in interpretation of laboratory results

Yıl 2013, Cilt: 22 Sayı: 2, 252 - 258, 01.06.2013

Clinical laboratories should minimize all the sources of variations (preanalytical, analitical and biological variations) and manage them during the entire process leading to the laboratory report. Biological variation data of analytes has been widely used in for many purposes, such as evaluating the significance of changes in serial results which is known as reference change values. Conventional population based reference values do have serious intrinsic problems and thus, there is a need for revisiting practical applications of these values for getting more useful laboratory data. This paper explains the magnitude of within- and between subject biological variation of analytes and details the reference change value applications of biological variation data.

Laboratuvar Sonuçlarının Değerlendirilmesinde Analitlerin Biyolojik Varyasyon Verilerinin Önemi

Klinik laboratuvarlar, laboratuvar süreçleri ile ilişkili tüm varyasyon kaynaklarını (preanalitik, analitik ve biyolojik varyasyonlar) en alt düzeye indirmeli ve laboratuvar sonucu verilene kadar tüm süreci yönetmelidirler. Analitlerin biyolojik varyasyon verileri referans değişim değeri olarak bilinen seri ölçümler arasında anlamlı farklılıkların değerlendirilebilmesi gibi pek çok farklı amaç için sıklıkla kullanılmaktadır. Geleneksel olarak kullanılan popülasyona dayalı referans değerlerinin kendine özgü problemleri bulunmaktadır ve bundan dolayı daha yararlı laboratuvar verileri elde edebilmek için bu değerlerin pratik uygulamalarının yeniden gözden geçirilmesi gerekmektedir. Bu makalede analitlerin birey-içi ve bireyler-arası biyolojik varyasyonlarının önemi açıklanarak biyolojik varyasyon verilerinin referans değişim değeri hesaplanması ve uygulamaları anlatılmıştır.
