The shake test, the tap test and the turbidity test were evaluated to determine their accuracy in predicting lung function maturity, ie their ability to predict respiratory distress syndrome (RDS). The turbidity test was the most efficient with a sensitivity of 60%, a specificity of 97%, a positive predictive value of 82% and a negative predictive value of 92%. The shake test had a sensitivity of 40%, a specificity of 95%, a positive predictive value of 63% and a negative predictive value of 88%. The tap test at 2 minutes had a sensitivity of 57%, a specificity of 78%, a positive predictive value of 35% and a negative predictive value of 89%. It was fortuitous that the simplest and cheapest test was found to be the most efficient test of the three. We recommend that the turbidity test or at least one of these tests should be used to determine the maturity of lung function when non-urgent elective deliveries are contemplated, to help reduce the incidence of RDS in this group of patients. 相似文献

目的探讨尿液检验中试纸法及镜检法的效果,并进行分析。方法选取2016年2月~2018年1月在本院进行尿液检验的198例患者作为研究对象,采用随机抽签的方式分为对照组和观察组,每组各99例。对照组采用试纸法进行尿检,观察组采用镜检法进行尿检。观察并记录两种检测方法结果,并对比分析。结果镜检法和试纸法在检测中均能准确测出患者尿液中红细胞、白细胞的含量;试纸法及镜检法在检测阳性率、假阳性率、阴性率、假阴性率等方面无明显差异(P0.05)。结论传统单一的试纸法与镜检法在检测尿液时均能保证基本的正确性,在监测结果方面无明显差异。 相似文献

检验的及时性、全面性、准确性直接关乎临床诊断与治疗的效果。由于医学科学的快速发展,其中临床检验学已经发展为一门独立的学科,并已形成一个庞大的体系,包括的内容繁多、复杂,而检验新知识、新项目的普及和临床应用目前在国内却处于相对落后的态势,使其在临床工作中没有发挥出应有的作用,难免会出现漏诊误治的现象。造成这种状况的原因是多方面的,本文将结合实际调研对此作一简要分析,目的在于促进检验知识的普及和应用,使医护人员和患者重视检验,让检验更好地为人们的健康保健服务。 相似文献

The aim of this study was to correlate tuberculin reactivity with the Kveim test in sarcoidosis. Case records 1983–91 inclusive, of those patients with positive Kveim tests and recorded tuberculin tests in an acute regional general hospital serving south-west Ireland (counties Cork and Kerry) were reviewed. Of 39 patients with positive Kveim tests 28 (72%) were tuberculin negative to a test dose of 10 tuberculin units or more. The group was slightly though significantly younger (p <0.05) in age than the corresponding group (n = 11; 28%) with positive tuberculin tests. The incidence of tuberculin reactivity in the presence of Kveim reaction is higher than that expected for sarcoidosis. Corresponding studies in Britain and Scandinavia show a considerably lower tuberculin positive rate, which may be due to a lower prevalence of tuberculosis in these countries. However the younger age of the tuberculin negative group in our study may reflect a continuing decline in tuberculosis prevalence in south-west Ireland. 相似文献

OBJECTIVE: To evaluate the performances of 3 serological assays (direct agglutination test [DAT], fast agglutination screening test [FAST], recombinant protein [rK39] dipstick) test for use in primary care, for the diagnosis visceral leishmaniasis (VL) in Syria. METHODS: We utilized 267 serum samples obtained during 2007 from patient groups confirmed and suspected VL, confirmed cutaneous leishmaniasis, toxoplasmosis from endemic areas in Syria and control samples, and applied the 3 serological tests in the Damascus University, Damascus and Health laboratories at the same time, on these samples. RESULTS: Our data show that the tests were very sensitive, where the DAT was the most specific followed by FAST, then rK39 dipstick. CONCLUSION: Our study confirmed that all the tests performed well, and proved to be very important sero-diagnosis tools for visceral leishmaniasis. 相似文献

The universities are encouraged by the government nowadays to stimulate innovations and also to provide the proper machinery for assisting the protection and commercialisation of innovations. A better understanding of the innovation process may help to create an atmosphere suitable for inventions at the university. Examples can be taken from successful innovations previously made at the university. During the 1960's I made a series of inventions, which ultimately led to the development of the diagnostic test kit industry. The first, which I made as an undergraduate, was a simple and reliable test kit for diagnosis of pregnancy. This was followed by the solid phase radioimmunoassay and a solid phase assay for vitamin B12; next, the dual specific non-competitive sandwich assay and the in-vitro test for diagnosis of allergy, called RAST (Radioallergosorbent test). Organon in Holland with the pregnancy test kit, and Pharmacia in Sweden with test kits for radioimmunoassay, became pioneers among the diagnostic test kit industries. Pharmacia Diagnostics later became one of the leading diagnostic test kit companies in the world and has continued to be so in the field of allergy diagnosis. Each one of these inventions started with a few unique observations leading to a technical development. The pregnancy test as well as the allergy test emerged from the development of assay methods with unique qualities with the subsequent search for appropriate applications. The foreseeing of a commercial value on a future market was a very important step. This was followed by the search for a suitable industry interested to exploit the invention with its new business opportunity i.e. apply for a patent, produce and market the products, which in my case consisted of the necessary reagents and equipments for particular diagnostic tests. Finally, an agreement had to be settled between the entrepreneur and the inventors. This report describes these inventions and particularly discusses some crucial steps of the innovation processes. 相似文献
