Effects of Different Rare Hb Variants on HbA1c Measurement in Eight Methods
Randie R. Little et al. (2015) Journal of Diabetes and Science and Technology1
Introduction
The study examined analytical interference from 49 different less common variants comparing seven different HbA1c methods. HbA1c accuracy was assessed as well as the likelihood for the systems to report inaccurate results. The authors noted that previous studies with some assay methods have shown interference with HbA1c measurement from the four most common heterozygous Hb variants (HbAS, HbAE, HbAC, and HbAD).
Study Results
Bio-Rad HPLC systems outperformed other HbA1c testing systems. The VARIANT II TURBO System reported 97.7% accurate results in the presence of hemoglobin variants. The table below illustrates the clinical benefit of Bio-Rad ion-exchange HPLC for patient diagnosis and treatment.
Conclusion
The authors concluded that in order to ensure accurate HbA1c results, it’s important to know if patients have a hemoglobin variant and if so, how that variant affects their HbA1c results. Laboratories should take care when reporting results if a variant is suspected.

Bio-Rad HPLC Reveals HbF for a Diagnosis You Can Trust
Are You Reporting Valid HbA1c Results?
HbA1c testing methods that don't see common hemoglobin variants or elevated levels of hemoglobin F might lead to misdiagnosis and unnecessary or delayed patient treatment.
Case Study Results:**
- Bio-Rad VARIANT II TURBO System reveals the presence of HbF so you can confidently report HbA1c results to your clinicians.
- Immunoassays do not reveal the presence of HbF. So you might not know the result was invalid and unknowingly report incorrect results.
For Quality Patient Care
The VARIANT II TURBO System brings speed, efficiency and accuracy to laboratories demanding a robust system for processing thousands of tests a month.
