Summary
This study validates a new automated analyzer for measuring Haemoglobin A2 (HbA2) and Foetal Haemoglobin (HbF). The method demonstrates high precision and accuracy, meeting the growing clinical demand for these tests.
Area of Science:
- Clinical Chemistry
- Analytical Biochemistry
- Hematology
Context:
- Accurate quantification of Haemoglobin A2 (HbA2) and Foetal Haemoglobin (HbF) is crucial for diagnosing and managing hemoglobinopathies.
- Existing manual methods can be labor-intensive and time-consuming.
- There is a growing clinical demand for rapid and reliable HbA2 and HbF measurements.
Purpose:
- To present the analytical performance of the first automated High-Performance Liquid Chromatography (HPLC) analyzer for HbA2 and HbF.
- To evaluate the precision, accuracy, and correlation of the automated method with established manual techniques.
- To establish reference values for HbA2 and HbF in an adult population.
Summary:
- The automated HPLC analyzer demonstrated excellent within-run (0.66-2.7%) and between-run (1.8-6.44%) imprecision.
- High correlation coefficients (r = 0.965 for HbA2, r = 0.999 for HbF) were observed when compared to manual methods.
- Established reference ranges: HbA2 (1.98-2.94%) and HbF (0-0.95%). Chromatograms of various hemoglobinopathies were also presented.
Impact:
- Validates an automated method for HbA2 and HbF analysis, addressing increased clinical demand.
- Provides a more efficient and accurate diagnostic tool for hemoglobin disorders.
- Facilitates improved patient care through timely and reliable laboratory results.
