Haemoglobin A1 levels in Nigerian diabetic patients using microcolumn affinity chromatography
African Journal of Medicine and Medical Sciences
|March 1, 1986
Summary
Glycated hemoglobin A1 (HbA1) testing using affinity chromatography is effective for diabetic Nigerians. This method is reliable even with sample storage at room temperature or refrigeration, proving useful in developing countries.
Area of Science:
- Clinical Chemistry
- Biochemistry
- Medical Diagnostics
Background:
- Diabetes mellitus management requires regular monitoring of glycemic control.
- Glycated hemoglobin A1 (HbA1) levels reflect average blood glucose over 2-3 months.
- Accurate and accessible HbA1 measurement methods are crucial, especially in resource-limited settings.
Purpose of the Study:
- To evaluate the efficacy of disposable microcolumn kits based on affinity chromatography for measuring HbA1 levels in Nigerian diabetic patients and controls.
- To assess the impact of short-term storage of whole blood samples at room temperature and refrigeration on HbA1 measurement accuracy.
- To determine the suitability of this method for use in tropical developing countries.
Main Methods:
- HbA1 levels were measured in 45 diabetic Nigerians and 13 non-diabetic controls using affinity chromatography microcolumn kits.
- Whole blood samples were stored for one week at room temperature and in a refrigerator to evaluate storage effects.
- Statistical analysis (t-tests) was used to compare HbA1 levels between groups and assess storage impact.
Main Results:
- Mean HbA1 levels were significantly higher in diabetic patients (12.1 +/- 5.6%) compared to controls (5.2 +/- 0.90%) (P < 0.001).
- Newly diagnosed, untreated diabetic patients showed higher HbA1 levels (14.4 +/- 5.0%) than treated patients (9.5 +/- 2.9%) (P < 0.01).
- Sample storage for one week showed non-significant changes in HbA1 levels at room temperature (9.8 +/- 3.6%) and refrigeration (11.0 +/- 4.2%) compared to baseline (10.3 +/- 4.2%).
Conclusions:
- Glyc-affinity micro-column chromatography is a satisfactory and potentially useful method for HbA1 measurement in developing countries.
- The method is user-friendly and suitable for ambient room temperatures, eliminating the need for specialized equipment.
- Short-term storage of samples does not significantly affect HbA1 measurement results, enhancing its practicality.
