The ARKRAY Variant Hemoglobin Library contains the records of hemoglobin variants that have been analyzed on ARKRAY glycohemoglobin analyzers. This website serves as an educational tool for ARKRAY users when encountering patient samples that may contain hemoglobin variants.

Each record contains the measurement result from a specific patient sample. As variations may exist between patient samples with the same type of hemoglobin variant, users are advised against interpreting each record as a general representation of that hemoglobin patient samples containing possible hemoglobin variants. In addition, the information presented in this website cannot be used to diagnose the hemoglobin status of patient samples. Instead, users are required to consider the proper procedure for determining hemoglobin status of patient samples e.g. genetic testing.
