Abstract

To verify whether precision of lipids analyses by a new portable device, CardioCheck(TM), were in agreement with the guidelines of the National Cholesterol Education Program (NCEP). Serum samples from hundred outpatients were collected for the determination of total Cholesterol (TC), HDL-cholesterol (HDL-C) and triglycerides (TG). These samples were analysed simultaneously by the CardioCheck(TM), and by the automatic enzymatic methods routinely used at the biochemistry laboratory. Precision was determined by repeating 20 times the evaluation of normal and high control sera. Precision for panel TC was 3.29 % (NCEP ≤ 3 %), for panel HDL-C was 6.1 % (NCEP ≤ 6%) and for panel TG was 18.9 % (NCEP ≤ 5 %), TC was 5.3 % , HDL-C 14.5 % , TG was 15.7 %. Precision lipids evaluation by the CardioCheck(TM) are within the guidelines of the NCEP. Therefore the CardioCheck(TM) seems to be a nonreliable alternative to the conventional biochemical routine

Abstract

Yeni kullanılmaya başlayan CardioCheck(TM) taşınabilir lipid analizörünün, NCEP’e (National Cholesterol Education Program) göre değerlendirilmesi amaçlanmıştır. Total Kolesterol (TK), HDL Kolesterol (HDL-K) ve Trigliserid (TG) düzeyleri saptamak için, polikliniğe gelen yüz hasta çalışmaya dahil edilmiştir. Örnekler eş zamanlı olarak CardioCheck(TM) lipid analizöründe ve Biyokimya Laboratuvarında otomatik enzimatik metod ile çalışıldı. Tekrarlanabilirlik çalışması, normal ve yüksek kontrol serumunda yirmişer kez saptandı. Tekrarlanabilirlik çalışmasının varyasyon katsayısı (% CV) sonuçları; panel TK % 3.29 ( NCEP % ≤ 3) , panel HDL-K % 6.1 ( NCEP ≤ %6), panel TG % 18.9 ( NCEP ≤ % 5), TK % 5.3, HDL-K % 14.5, TG % 15.7 idi. CardioCheck(TM) tekrarlanabilirlik sonuçları NCEP’e göre değerlendirildi. CardioCheck(TM) lipid analizörünün geleneksel rutin ölçüme bir seçenek olacak kadar güvenilir olmadığı ortaya kondu
