Abstract

Objectives: Reliable reference intervals are important in the interpretation of labo ratory data. Several analytes vary notably among different age and gender group Some routine biochemical assays may change with increasing age. In this study we aimed to determine reference intervals for routine chemistry assays in health individuals who are 40 years old or over. Methods: Healthy reference individuals (133 male, 133 female; ages: 40-80) wer selected by a questionary. The 95% reference intervals were determined by non parametric method for the selected 21 analytes. The reference values calculated were compared with the reference intervals given by manufacturer and reported from other studies. Results: Significant differences were observed for the reference intervals of som analytes (Urea, Creatinine, Uric Acid, Albumin, Triglycerides, High density lipo protein-Cholesterol, Alanine Aminotransferase, Gamma Glutamyl Transferase, To tal Bilirubin, Direct Bilirubin, Sodium, Chloride) between males and females. Ca culated reference intervals for Urea, Creatinine, Uric Acid, Total Calcium, Ionized Calcium, Total Protein, Aspartate Aminotranferase, Alanine Aminotransferase Alkaline Phosphatase, Gamma Glutamyl Transferase, Total Bilirubin, Direct Bil rubin, Sodium, Potassium and Chloride were similar with the values given by th manufacturer. Reference intervals for Albumin and Lipid profile were observed higher than the values given by the manufacturer. Conclusion: We suggest that studies determining reference intervals will help cl nicians identify and evaluate their own patient populations.

Özet

Amaç: Laboratuvar verilerini yorumlamada, güvenilir referans aralıklarının önemli bir yeri vardır. Farklı yaş ve cinsiyet grupları arasında, çeşitli testler önemli düzeyde değişim göstermektedir. Bazı rutin biyokimyasal testler, ilerleyen yaşla değişebilmektedir. Klinik laboratuvarlar, genellikle üretici firma tarafından önerilen referans aralıklarını kullanırlar. Bu çalışmada, 40 yaş ve üstü sağlıklı bireylerde 21 biyokimyasal parametrenin referans aralıklarını belirlemeyi amaçladık. Yöntem: Sağlıklı referans bireyler (133 erkek, 133 kadın; yaş: 40-80) anket yöntemiyle seçildi. %95 referans aralıkları parametrik olmayan yöntem ile seçilmiş 21 biyokimya testi için hesaplandı. Üretici firmanın verdiği ve literatürden elde edilen referans aralıkları ile karşılaştırıldı. Bulgular: Bazı testlerin (Üre, Kreatinin, Ürik Asit, Albumin, Trigliserid, Yüksek Dansiteli Lipoprotein-Kolesterol, Alanin Aminotransferaz, Gama Glutamil Transferaz, Total Bilirubin, Direkt Bilirubin, Sodyum ve Klorür) referans aralıklarında kadın ve erkekler arasında anlamlı fark saptandı. Üre, Kreatinin, Ürik Asit, Total Kalsiyum, İyonize Kalsiyum, Total Protein, Aspartat Aminotransferaz, Alanin Aminotransferaz, Alkalen Fosfataz, Gama Glutamil Transferaz, Total Bilirubin, Direkt Bilirubin, Sodyum, Potasyum ve Klorür için elde edilen referans aralık değerlerinin üretici firmanın tavsiye ettiği referans aralıklar ile uyumlu olduğu; Albümin ve Lipid profili için elde edilen referans aralıklarının üretici firmanın değerlerinden yüksek olduğu tespit edildi. Sonuç: Yapılacak referans aralık çalışmalarının, hekimlerin kendi popülasyonlarını tanımasında ve hastalarını değerlendirmesinde önemli katkılar sağlayacağını düşünüyoruz.
