These numbers of blood and urine samples of addicts in clinics of welfare organization, during detoxification treatment or maintenance treatment were screened for abuse drugs presence. The all of samples were tested through as a view of clinical laboratory methods. Age ranges of female patients were 35 ~ 15 and age range of males patients were 45 ~ 15. All patients filled questionnaire and satisfy forms too. First, all fresh urine and blood samples were examined to confirm presence drugs abuses, depend on their addiction and treatment, so all samples were confirmed by two tests. Then they were examined to other clinical laboratory tests. All data were analyzed by t-test and were Anova one way and two ways of Anova Turkey, and p 〈 0.05 was considered significant. The p-value of this study was p = 0.0001. The results of this study were showed that 4% of abusers had mild increase in hematocrite level and 2% of narcotic drugs abusers had mild lower level of blood sugars than normal range and 4% of participants had increase liver enzymes such ALT （alanine transferase）, AST （aspartat transferase）, ALP （alkaline phosphatease） and 1% of them had renal failure. Although blood level BUN （blood urea nitrogen） and creatinin were examined to evaluation of their renal failure .The results in Tabriz/Iran undrevision of welfare organization clinics were approximately showed that positive results of addiction are in each of urine and blood samples. Because some of abusers directly consumed full long time agonist or partial agonists＇ drugs such as methadone and buprenorphine for their maintenance therapy in clinics. Also doing test on blood samples has high importance in distinguishing and confirmation of drugs abuse in samples. Also in this study we conclude that among all drug analytical methods the cheapest and easiest test to screening opioids and other abuse drugs in urine and blood samples is strip test for rapid diagnosis, also tests on blood samples have high importance as a view point of accuracy to distinguishing of drugs abuse, and serum levels of some other parameters showed all abusers patients situation such as liver and renal dysfimction through clinical laboratory tests.展开更多

Methods: 40 blood samples were selected in the completely random manner within the range from July 2019 to December 2020.Conduct statistics and analysis on the inspection of all specimens, clarify the causes of the unqualified specimen inspection, and formulate the solution measures according to the reasons. Results: of 40 blood specimens, 21 specimens failed the inspection, and the unqualified rate was 52.50%. Many reasons caused the unqualified blood specimens, mainly including timely failure, specimen coagulation and poor standardization of blood sampling. Conclusion: during the test of blood samples. Therefore, in order to improve the qualified rate of blood specimen inspection, it must fully clarify the causes of the unqualified inspection phenomenon, and take timely solution measures.展开更多

It is mainly a system to analyze the information of blood samples throughout 2020, to carry out regression statistical analysis on unqualified samples, and to summarize the relevant specific factors affecting the unqualified blood samples, and to formulate qualified countermeasures based on the relevant specific factors. Results: the main purpose is to analyze the specific conditions of unqualified blood samples in community clinical tests and the possible specific reasons. Relevant unqualified blood samples are counted, and relevant specific factors of unqualified blood samples are analyzed by regression. Meanwhile, according to relevant factors, experts are invited to give specific introduction and formulate relevant solutions. Among the samples found so far, 51 samples failed, with a failure rate of 0.51%. Conclusion: blood samples are susceptible to the interference of patient factors, blood collection operation factors, sample transportation and inspection factors and inspection operation factors. It is very important to adopt relevant prevention strategies to ensure the qualified samples.展开更多

Methods: in this study, 120 patients with the error in the routine blood test results from March 2020 to March 2021 were randomly selected as the study subjects, and the clinical data of all the study subjects were analyzed retrospectively. All patients received 2mL blood collection from peripheral blood and 14ml of venous blood. The venous blood samples were divided into 7 groups, among which group 1 was tested immediately after collection, groups 2 and 3 were stored in refrigerator (4℃) and room temperature, groups 4 and 4 hours respectively, group 6 and 7 were treated with 1.6 mg/ml and 2.8 mg/ml anticoagulant respectively. Peripheral blood needs to be tested immediately. The root causes of common errors are summarized, and the influence of different blood collection location, placement time and anticoagulant concentration on the routine blood test indicators is discussed, and the corresponding solutions are summarized. Results: the results of this study showed that platelet content in peripheral blood samples was significantly lower than venous blood, with significantly different data between groups (P <0.05). Blood samples were retained for 2 hours after collection, the hemoglobin concentration and platelet content were lower than the 4-hour retained samples, and the data differences between groups were significant (P <0.05).Blood samples were stored in the refrigerator, the hemoglobin concentration was lower than those stored at room temperature, and there were significant differences between groups (P <0.05).After the blood samples were treated with 2.8 mg/ml anticoagulant concentration, the content of each index was significantly higher than that treated with 1.6 mg/ml, and the data between the two groups varied significantly (P <0.05).Among the routine blood tests, 120 subjects had the error in the routine blood test indicators, including the unreasonable anticoagulant concentration, long inspection time, unreasonable storage and personal factors of the subjects. Conclusion: in the routine blood test, many factors resulted in the test error. The hospital should clarify the main influencing factors, improve the efficiency and quality of routine blood test by strengthening the training of relevant personnel, actively communicating with the subjects, and making reasonable use of anticoagulant, reducing the probability of error, and provide reliable support for the clinical diagnosis and treatment of doctors.展开更多

Methods: 138 hospitalized patients with infection from January 2018 to December 2020 in our hospital, including 80 male patients and 58 female patients, were selected and randomly divided into two groups, 69 in the experimental group and 69 in the control group. Both groups were treated with routine medical treatment. Results: in this study, 69 patients in the experimental group were tested with clinical microorganism and the control group was tested with routine method. By comparing and analyzing the data, the infection rate in the experimental group was much lower than that in the control group. This result shows that the use of clinical microorganism test has a better effect on preventing infection. The difference was statistically significant. Conclusion: the clinical microbiological examination can quickly give feedback to the patients' disease conditions and provide the doctors with the infection incidence data several times a day, which is of great significance in preventing infection.展开更多
