    Abstract:
    OBJECTIVE: To evaluate the feasibility of URIT-12 hemoglobin analyzer for fast measurement of hemoglobin concentration. METHODS: Hemoglobin concentration was detected in 100 random blood samples using URIT-12 hemoglobin analyzer and Coulter LH-750 hematology analyzer. RESULTS: The two analyzers showed good correlation of the results (r=0.994) without significant difference between them (P>0.05). The linear range of URIT-12 hemoglobin analyzer was 46-240 g/L, and in the repeated measurements (20 times) of 3 batches of blood samples with low, moderate and high hemoglobin concentrations, the within-batch coefficient of variation of URIT-12 hemoglobin analyzer, from low to high concentrations, were 2.13%, 2.17%, and 2.33%, respectively. In the measurement of 4 batches of high-fat, high-bilirubin, high-globin and high-white-blood-cell blood samples, the interference rate of the former 3 samples were all less than 4% by the two devices, but that of the fourth sample was 10% by URIT-12 hemoglobin analyzer and 7% by Coulter LH-750 analyzer. CONCLUSION: The results detected by URIT-12 hemoglobin analyzer have high accuracy and precision and is easy to operate, fast-testing and portable.
