Aim: Beta thalassemias are common autosomal recessive inherited hemoglobinopathy worldwide. Hemoglobin A2 levels are the most important parameter used to determine beta-thalassemia carriers. One of the most commonly used methods for HbA2 measurement is high-performance liquid chromatography (HPLC). We aimed to compare the HbA2 levels of Lifotronic H9 and Primus Ultra2 HPLC systems.

Material and Methods: A total of 51 individuals, 19 females and 32 males were included in our study. The compatibility of the results was demonstrated by the Bland-Altman plot and Passing-Bablok regression analysis.

Results: The geometric mean ratio of values was 0.95 (95% limits of agreement 0.6 to 1.49) in the Bland-Altman plot. 95% confidence intervals were observed as -1.03 - 1.30 (intercept) and 0.55-1.33 (slope) in Passing-Bablok regression analysis.

Conclusion: We reported first time measuring compatibility of Lifotronic H9 HPLC system in terms of HbA2 levels by using Primus Ultra2.
