Abstract:
Objective To evaluate the automatic biochemical analyzer when used to detect urinary vanilmandelic acid (VMA), and to compare it with manual method. Methods The automatic biochemical analyzer using homogenous enzyme immunoassay technology was compared with the manual method on accuracy, precision, linear range, recovery rate, anti-interference capability and etc when used to detect VMA.The comparison was also carried out on positive rate and etc when the two methods were used to test the urine specimens of the healthy subjects and suspected patients of hypertension, hyperthyroidism and hypothyroidism. Results The two methods both had the results on accuracy, precision, linear range, recovery rate, anti-interference capability meet the requirements described in the instruction of reagent kit, while the analyzer gained advantages over the manual method.The positive rates by the two methods for testing urine specimens were similar,while the analyzer behaved better in diagnosing the patient with critical value.Conclusion The analyzer proves better than the manual method when used to detect VMA,and thus is worthy promoting in clinical trial.
