Abstract

Objective: Coagulation tests are sensitive to pre-analyticalvariables. The aim of our study is to identify the effect oftransportation and freeze-thaw status on for Factor VIII,Factor IX, Anti-thrombin III, Protein S, Protein C, Pro thrombin time (PT) and Activated partial thromboplastintime (aPTT). Materials and methods: The study was performed on 102plasma samples obtained from 34 healthy volunteers.The samples were divided into three groups. Group A wasanalyzed whereas group B, C were frozen at −20°C. After24 h, group B and C were transported for 2 h. Followingthe transfer, group B was analyzed and C was frozen at−20°C. After 24 h, group C was analyzed. Analyses of samples were performed in Thrombolyzer-XRM for PT, aPTT, Factor VIII, Factor IX, Anti-thrombin III, Protein C and Protein S. Results: There were significant variations for PT, aPTT, Protein S, Factor VIII and Factor IX for group A&B and A&Ccomparisons in different stability criteria approaches. In significant change limit and percentage change calcula tions Protein S, Factor VIII and IX showed significant dif ferences. For acceptable change limit approach, aPTT and Factor IX showed significant changes. Conclusion: Laboratories should take precautions fortransportation and freeze-thaw cycles to prevent inaccu rate results.

Özet

Amaç: Koagulasyon testleri analiz öncesi değişkenlerekarşı duyarlıdır. Çalışmamızın amacı, donma-çözünme vetaşıma etkisinin Faktör VIII, Faktör IX, Anti-trombin III,Protein S, Protein C, Protrombin zamanı (PT) ve Aktiveparsiyel thromboplastin zamanı (aPTT) sonuçlarına etki sini araştırmaktır. Gereç ve Yöntem: Çalışma 34 sağlıklı gönüllüden eldeedilen 102 plazma örneğinde gerçekleştirildi. Örnekler 3gruba ayrıldı: Grup A örnekleri hemen analiz edilirkenGrup B ve Grup C örnekleri −20°C’de donduruldu. 24 saatsonra Grup B ve Grup C örnekleri 2 saat süre boyuncataşındı. Taşınmanın ardından, Grup B örnekleri analizedilirken Grup C örnekleri tekrar −20°C’de donduruldu.24 saat sonra Grup C örnekleri analiz edildi. Örnekler den Thrombolyzer-XRM cihazında, PT, aPTT, Faktör VIII,Faktör IX, Anti-trombin III, Protein C ve Protein S testleriçalışıldı. Sonuçlar: Farklı stabilite kriterleri yaklaşımlarına göre PT,aPTT, Protein S, Faktör VIII and Faktör IX sonuçlarındaGrup A&B ve A&C karşılaştırmalarında önemli farklılık lar elde edildi. Anlamlı değişim sınırı ve yüzde değişimhesaplamalarında Protein S, Faktör VIII and Faktör IXsonuçlarında, kabul edilebilir değişim sınırı yaklaşımındaise aPTT ve Faktör IX sonuçlarında anlamlı farklılıklarbulundu. Tartışma: Laboratuvarlar yanlış sonuçları önlemek içinörneklerin taşınma ve donma-çözünme döngüleri içinönlemler almalıdır.
