                            <p>Amaç: Amerikan Diyabet Derneği (ADA), diyabetin teşhisinde ve hastalık açısından yüksek risk altındaki kişilerin taranmasında HbA1c&#039;nin kullanılmasını onaylamıştır. Çalışmamızda HbA1c&#039;nin rutin ölçümü için Lifotronic H9 Yüksek Performanslı Sıvı Kromatografi (HPLC) analizörünü türbidimetrik immün inhibisyon (TINIA) kullanan Roche Cobas c501 yöntemiyle karşılaştırmalı olarak değerlendirmeyi amaçladık.Gereç ve Yöntemler: Araştırmaya toplam dört yüz altmış dokuz katılımcı dahil edildi. Bunlardan 297&#039;sinin (%63,3) kadın, 172&#039;sinin (%36,7) erkek olduğu belirlendi. Yöntem karşılaştırması doğrusal regresyon ve Bland-Altman grafikleri ile yapıldı.Bulgular: HPLC ve TINIA yöntemiyle elde edilen HbA1c değerleri sırasıyla 6.78±1.76 ve 6.70±1.39 elde edildi. Ancak bu fark istatistiksel olarak anlamlı değildi (p=0.461). Passing-Bablok regresyon analizi, oldukça yüksek bir korelasyon katsayısının (r=0.974) yanı sıra, HbA1c için 0.90&#039;lık bir eğim (güven aralığı (CI) 0.89-0.91) ve 0.59&#039;luk bir kesişme noktası (CI 0.50-0.67) gösterdi. Tüm hastalarda tekrarlanan ölçümler üzerinde gerçekleştirilen Bland-Altman analizi, +%0.08&#039;lik bir sapma (CI 0.05-0.10) ile karakterize edilen güçlü düzeyde bir anlaşmaya işaret etti. Analiz, iki standart sapmanın (2 SD) alt sınırı -0.47 (CI -0.52 ila -0.43) ve üst sınırı 0.63 (CI 0.59 ila 0.68) olarak belirlediğini ortaya çıkardı.Sonuç: HPLC ve TINIA&#039;nın kalitesi ve performansı karşılaştırılabilir ve mükemmel bir korelasyon gösterdi. Klinisyenler ve klinik biyokimyacılar, diyabetin teşhisi, tedavisi ve takibi konusunda işbirliği yapmalıdır. Bu işbirliği etkili hasta bakımı için gereklidir.</p></trans-abstract>

In our study, we aimed to evaluate the Lifotronic H9 High-Performance Liquid Chromatography (HPLC) Analyzer for the routine measurement of HbA1c in comparison to the Roche Cobas c501 method, which employs turbidimetric immuno-inhibition (TINIA).Material and Methods: A total of four hundred sixty-nine participants were included in the study. Among them, two hundred ninety-seven (63.3%) were identified as female, while one hundred seventy-two (36.7%) were male. Method comparison was done by linear regression and Bland-Altman plots. Results: HbA1c values obtained through the HPLC method were found to be greater than those obtained via the TINIA method, with measurements of 6.78±1.76 and 6.70±1.39, respectively. However, this difference was not statistically significant (p=0.461). The Passing–Bablok regression analysis indicated a slope of 0.90 (confidence interval (CI) 0.89-0.91) and an intercept of 0.59 (CI 0.50–0.67) for HbA1c, alongside a notably high correlation coefficient (r=0.974). Bland-Altman analysis conducted on repeated measurements across all patients indicated a strong level of agreement, characterized by a bias of +0.08% (CI 0.05–0.10). The analysis revealed that the two standard deviations (2 SD) established the lower limit at -0.47 (CI -0.52 to -0.43) and the upper limit at 0.63 (CI 0.59 to 0.68).Conclusion: The quality and performance of HPLC and TINIA are comparable and exhibit excellent correlation. Clinicians and clinical biochemists should collaborate on managing diabetes mellitus regarding diagnosis, treatment, and follow-up. This collaboration is essential for effective patient care.</p></abstract>
