Abstract
Purpose:Using preservative urine tubes for urine analysis has been made a new era. A proportion of compounds in a preservative tube can be listed as follows: Sodium Propionate (94%), ethylparaben (5.6%) and chlorhexidine (0.4%).
Patients and Methods:We study the urinary tube containing preservative (Becton-Dickinson, Franklin Lakes, USA) additives aimed to study whether the effect on some biochemical tests. 24-h urine samples (n=118) were obtained from outpatients for routine urine analysis. They were divided in to the two tubes: containing preservatives tubes and additive free tubes. Six biochemistry parameters (protein, calcium, urea, phosphorus, creatinine, microalbumin) were tested on Beckman Coulter AU680 analyzer.
Results:Results: The results of phosphor in two urine samples were decreased significantly in all of the time points in stability studies(p= 0.02, p < 0.01).
Conclusion:Conclusion: We can conclude that tubes containing preservatives could be used to analyze biochemical parameters which were analyzed. But urine phosphor measurement with the additive tubes should be done promptly after delivery to the laboratory.

Abstract
Amaç:İdrar analizi için koruyucu içeren idrar tüplerinin kullanılması yeni bir dönem olmuştur. Koruyucu içeren tüplerdeki bileşikler şu şekilde sıralanabilir: Sodyum Propiyonat (% 94), etilparaben (% 5.6) ve klorheksidin (% 0.4).
Hastalar ve Yöntem:Biz çalışmamızda koruyucu içeren idrar tüplerinin (Becton-Dickinson, Franklin Lakes, USA) bazı biyokimyasal parametreler üzerine etkisini incelemeyi amaçladık. Rutin idrar analizi için gelen 24 saatlik idrar örneklerinden 118 tanesi çalışmaya alındı. İdrar örnekleri 2’ye porsiyonlandı: Koruyucu içeren tüpler ve katkı maddesi içermeyen tüpler. Beckman Coulter AU680 analizöründe altı biyokimya parametresi (protein, kalsiyum, üre, fosfor, kreatinin, mikroalbümin) test edildi.
Bulgular:İki idrar örneğindeki fosforun sonuçları stabilite çalışmalarında tüm zaman noktalarında anlamlı olarak azaldı (p = 0.02, p <0.01).
Sonuç:Biyokimyasal parametreleri analiz etmek için koruyucu içeren tüplerin kullanılabileceği sonucuna varabiliriz. Ancak, koruyucu içeren tüplerle idrar fosfor ölçümü laboratuvara teslim edildikten hemen sonra yapılmalıdır.
