Abstract

There is few information on the effect of light on serum vitamin B12 and folate measurements in the literature. Additionally, different kits and instrument systems for the measurement of these analytes can be affected by light in a different way. In this study, we aimed to investigate the effect of light on these analytes. Blood specimens were collected from 11 healthy volunteers in 16*100 mm Vacutainer® SST tubes. Sera were separated and aliquoted in two groups of plain polypropilen tubes capped and stored in dark (Group 1) and light (Group 2) at room temperature. Duplicate vitamin B12 and folate measurements were performed immediately (0 h, initial point), and after 8 h and 24 h from the initial point. The measurements were performed in an Immulite 2000 analyzer with reagents from the manufacturer. The significance of differences between and within groups were analyzed by repeatedmeasures ANOVA. When the 0 h specimens were considered reference, vitamin B12 measurements were not significantly affected by light up to 24 hours (p>0.05). Whereas folate measurements were significantly affected by light at 24th h after drawing. In conclusion, there is no need to store the samples in dark for vitamin B12 and folate measurements which performed in the same working day of drawing.

Özet

Literatürde serum vitamin B12 ve folat ölçümlerine ışığın etkisi hakkında yeterli bilgi yoktur. Ayrıca, bu analitlerin ölçümlerinde kullanılan farklı kit ve cihaz sistemleri ışıktan farklı şekilde etkilenebilir. Bu çalışmada ışığın bu analitler üzerine etkisini araştırmak amaçlanmıştır. Kan örnekleri 11 sağlıklı gönüllüden 16*100 mm’lik Vacutainer® SST tüplere alındı. Serumlar ayrıldıktan sonra düz polipropilen tüplere bölündü ve tüplerin bir bölümü karanlıkta (Grup 1), geri kalanı ışık altında (Grup 2) oda sıcaklığında kapakları kapalı olarak bekletildi. Örneklerde işlem tamamlandıktan hemen sonra (0. saat) ve bundan 8 ve 24 saaat sonra çift olarak vitamin B12 ve folat ölçümleri yapıldı. Ölçümler Immulite 2000 analizöründe üretici firmanın ayıraçları ile yapıldı. Gruplar arasındaki farkın önemi “tekrarlanan ölçümler ANOVA” ile yapıldı. Başlangıç değerleri esas alındığında vitamin B12 ölçümlerinin 24 saate kadar ışıktan etkilenmediği görüldü (p>0.05). Folat ölçümleri ise kan alımından sonraki 24. saatte ışıktan etkilendi. Sonuç olarak, vitamin B12 ve folat ölçümleri kan örneğinin alındığı işgünü yapılacaksa, örneklerin karanlıkta saklanmasına gerek yoktur.
