[2025-10-02T00:32:05.220119] [PI reasoning] **Determining HbA1c measurement methods**

I’m tasked with figuring out the best method to measure HbA1c among the options given. In clinical labs, ion-exchange high-performance liquid chromatography (HPLC) is typically seen as the gold standard. It’s widely recognized as the reference method by NGSP. While affinity chromatography might work, it may not effectively separate hemoglobin variants. Considering this, if the question is from an Indian medical exam context, I suspect ion-exchange chromatography might be the best answer. I'll double-check quickly!
