What is a HbA1C Chromatogram Graph?
A chromatogram graph is a detailed visual record generated by our HPLC (High-Performance Liquid Chromatography) system during your HbA1c test. It illustrates how the different components of your blood sample are separated, detected, and precisely measured.
Each peak on the graph represents a specific form of hemoglobin, including HbA1c, which reflects your average blood glucose levels over the past two to three months. The height and shape of these peaks help verify the accuracy and quality of your results.
At LHC Lab, we use the same advanced HPLC technology trusted by NHS hospitals, ensuring that your results are highly accurate, reliable, and consistent. The chromatogram graph also serves as an important element of our internal quality control process, allowing our laboratory scientists to confirm that your test was performed correctly and free from contamination or interference.
What Makes HPLC the “Gold Standard” Method
The term “gold standard” refers to diagnostic methods that meet the highest scientific and clinical accuracy standards. HPLC is considered the gold standard for HbA1c testing because it provides:
- Analytical specificity – the ability to accurately distinguish HbA1c from other hemoglobin variants.
- Reproducibility – consistent and comparable results across different laboratories and instruments.
If you would like a copy of your chromatogram graph to share with your doctor or for your personal records, we are happy to provide it. Please email your request to info@lhclab.co.uk
