Description

Hemoglobin A2-Liangcheng is a highly purified, standardized hemoglobin variant used as a critical reference material and calibrator in clinical diagnostics. This product is essential for ensuring the accuracy and reliability of laboratory testing systems, particularly in the analysis of hemoglobinopathies. It is primarily required by manufacturers of in-vitro diagnostic (IVD) kits, clinical research organizations, and large-scale clinical laboratories for quality control and assay development.

Application

• Primary Calibrator/Standard for IVD Kits: Serves as a traceable reference material for calibrating diagnostic assays measuring Hemoglobin A2 (HbA2) levels.
• Quality Control (QC) Material: Used in internal and external quality assurance programs for clinical chemistry and hematology analyzers.
• Research and Development: A key component in the development and validation of new diagnostic methods for thalassemia and other hemoglobin disorders.
• Method Verification: Employed by laboratories to verify the performance of chromatographic (HPLC, CE) and immunoassay methods.
• Proficiency Testing: Incorporated into samples for inter-laboratory comparison schemes to ensure consistent results across testing sites.
