ABSTRACT
Objective To investigate the detection results of GHB with different instruments, and to provide reliable basis for improving the accuracy of GHB detection. Methods ADVIA 1650 biochemical analyzer and HA-8160 glycosylated hemoglobin analyzer were used. The accurate detection of glycosylated hemoglobin in 100 healthy people was carried out, and the related data were recorded and analyzed statistically. Attention should be paid to this group according to glycosylated hemoglobin detection value, that is, within 6.5％ for A group, 6.5％-10.0％ for B group, more than 10％ for C group, and compare the above-mentioned different grouping of corresponding instrument glycosylated hemoglobin detection value. Results The analysis showed that there was no significant difference between the two groups of C instrument glycosylated hemoglobin levels, but the level of glycosylated hemoglobin detected by A in group HA-8160 and group B was significantly higher than that of ADVIA 1650(P<0.05). Conclusion Different instruments have some differences in the detection value of glycosylated hemoglobin. Clinicians should judge the disease comprehensively according to the actual situation and other indicators.
ABSTRACT
Objective To investigate the basic status and the 15 quality indicators in clinical laboratory of medical institutionin in Qinghai provinces, and to understand the quality status.Methods Clinet-EQA system was applied by Qinghai Center for Clinical Laboratories to provide the electronic questionnaire for the clinical laboratory of 106 medical institutions in April 2016 and report related results online.The software of Clinet-EQA system and SPSS13.0 were used for 15 quality indicators for statiatical analysis,13 indicators expressed in rate were further evaluated with sigma scales.Results Totally 102 laboratories returned questionnaires, the rate was of 96.2%.8/13 quality indicators of the overall sigma levels were all >3.The average level of 4 quality indicators such as the sample type error rate was slightly lower than the national.Comparison of the 4 quality indicators of each grade hospital in Qinghai and the same grade hospital in the national, secondary hospital in clinical chemistry, immunology, clinical examination,microbiology in the four major performed better than tertiary hospital.In routine examination, pre-analytical TAT average level of clinical chemistry and immunology was about 50 min,and of blood,urine and stool was 45 min.Pre-analytical TAT in emergency examination for all four disciplines were about 15 min.Intra-analytical TAT for clinical chemistry was the longest,which was 120 min for routine examination and 40 min for emergency examination,respectiely.The average level of the median TAT of blood,urine and stool in routine examination of Intra-analytical in Qinghai was longer than the national.For example of clinical chemistry, routine examination both in pre-analytical TAT and in Intra-analytical TAT was statistically significant in different scales of laboratories,and emergency examination in pre-analytical TAT and in Intra-analytical TAT was not statistically significant.Conclusions 4/13 quality indicators which expressed in rate in the average level in Qinghai province were lower than the national,the average level of the median TAT of blood,urine and stool in routine examination of Intra-analytical in Qinghai was longer than the national.The laboratory should focus on the weak links and continue improvement.
ABSTRACT
Objective To analyze the factors related to the disqualification of urine routine and stool routine, and to formulate corresponding solutions. Methods In April 2014 to April 2017 our collected 600 cases of hospitalized patients, urine and stool samples for routine detection, made clear that cause unqualified samples related factors, and develop effective solution strategy. Results 600 cases in the selected routine urine, excrement and urine routine test specimens, the unqualified samples of total 110 cases, fraction defective is 18.33%, 490 qualified samples, percent of pass is 81.67%, the difference was statistically significant (P<0.05).There are a number of factors that cause the sample to fail, such as the contamination of the sample, the length of storage, the operation and the preparation. Conclusion In the process of actual diagnosis of disease, clinical result in urine, feces routine test specimen unqualified often appear, the reason is to a great extent, and the related nursing staff in urine and stool samples of patients before the lack of relevant guidance and so on, and nursing staff after the complete collection of specimens does not usually in accordance with the relevant standard of serious check, to avoid the sample inspection is unqualified, hospitals need to develop scientific inspection process, nurses in practice need to strict adherence to the process, and through intensive training, promote nursing staff awareness test, can to improve the qualification rate of sample test provide strong guarantee.
