EDTA-containing tubes are easy to find inclinical laboratories and do not need to be centrifuged, whichsaves time and effort.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Introduction: In this study, we aimed to investigate the shortterm stability and variability of cardiac troponin T (cTnI)in ethylenediamine tetraacetic acid (EDTA) whole blood,heparinized whole blood, and EDTA plasma.Methods: Thirteen patients with myocardial infarction wereincluded.
📊
Key Findings & Data:Venous blood samples (24 mL) from all patients werecollected into vacuum tubes with EDTA and heparin (BectonDickinson-USA), and analyses were performed on four differentgroups (one group for repeatability and three groups forstability).Results: There was no statistically significant difference incTnI concentrations at baseline, 2, 4, 6, 12, 24, and 48 hoursbetween the heparinized whole blood, EDTA whole blood, andEDTA plasma groups (group 2) (p>0.05).

Abstract

Introduction: In this study, we aimed to investigate the shortterm stability and variability of cardiac troponin T (cTnI)in ethylenediamine tetraacetic acid (EDTA) whole blood,heparinized whole blood, and EDTA plasma.Methods: Thirteen patients with myocardial infarction wereincluded. Venous blood samples (24 mL) from all patients werecollected into vacuum tubes with EDTA and heparin (BectonDickinson-USA), and analyses were performed on four differentgroups (one group for repeatability and three groups forstability).Results: There was no statistically significant difference incTnI concentrations at baseline, 2, 4, 6, 12, 24, and 48 hoursbetween the heparinized whole blood, EDTA whole blood, andEDTA plasma groups (group 2) (p>0.05). In the heparinizedwhole blood and EDTA plasma groups, there was a statisticallysignificant difference between cTnI concentrations at baseline,2, 4, 6, 12, 24, and 48 hours. In the EDTA whole blood group,there was no statistically significant difference between anytime points.Conclusion: The interclass and intraclass correlationcoefficients of the EDTA whole blood group were sufficientlyhigh, which indicates better stability. EDTA whole bloodsamples are preferable for cTnI measurement because they arestable for 48 hours. EDTA-containing tubes are easy to find inclinical laboratories and do not need to be centrifuged, whichsaves time and effort.

Özet

Amaç: Bu çalışmada EDTA tam kan, heparinize tam kan ve EDTA plazmasındaki kısa-süreli kardiyak troponin T (cTnI) stabilitesini ve değişkenliğini araştırmayı amaçladık. Yöntemler: Miyokard enfarktüsü geçiren 13 hasta dahil edilmiştir. Tüm hastalardan 24 mL venöz kan örnekleri EDTA ve heparinli vakum tüplerine alındı (Becton Dickinson-ABD) ve analizler 4 farklı grupta (tekrarlanabilirlik için 1 grup ve stabilite için 3 grup) gerçekleştirildi. Bulgular: Heparinize tam kan, EDTA tam kan ve EDTA plazma grupları arasında başlangıç, 2., 4., 6., 12., 24 ve 48. saat cTnI konsantrasyonları arasında istatistiksel olarak anlamlı bir fark yoktu (p>0,05). Heparinize tam kan ve EDTA plazma gruplarında, başlangıç, 2., 4., 6., 12, 24, 48 saat cTnI konsantrasyonları arasında istatistiksel anlamlı fark vardı. EDTA tam kan grubunda tüm saatler arasında istatistiksel olarak anlamlı fark yoktu. Sonuç: EDTA tam kan grubunun sınıflar arası ve sınıflar arası korelasyon katsayıları yeterince yüksekti, bu da daha iyi bir stabilite olduğunu göstermektedir. EDTA tam kan örnekleri cTnI ölçümünde tercih edilebilir, çünkü 48 saat stabildir. EDTA içeren tüplerin klinik laboratuvarlarda bulunması kolaydır ve santrifüjlemeye gerek kalmaz, zamandan ve emekten tasarruf sağlar
