31 healthy person with average ages of 76.3 (s.o=6.4), being the normal life were studied by 8 tests of BEC according to the instruction. The advantage of BEC 96 was actual evaluation of functions, suitable capacity of evaluation and time of evaluation. The Vietnamese version of test can be applied in practising the gerontology in Vietnam. However, the nervous-psychological tests were valuable only when related with the clinical and considered seperately for individuals.

The authors have examined the biochemistry activity of the hospital during the past 4-5 years. The numbers of the tests have been raising from 52,000 to 140,000/year. The different kinds of tests have been raising from 55 to 90. The quality of the tests is poor; now 90% of them give high precise results.

In Evidence-based Family Practice, requesting a diagnostic test should be based on two issues. First is whether the test is accurate and thus will significantly help in clinical decision making. Second is whether the test is appropriate and acceptable for the patient. This involves careful discussion of risks and benefits based on the physician’s knowledge and experience and the patient’s values and preferences.

OBJECTIVE: To evaluate the frequency and adequacy of statistical analyses in a general radiology journal when reporting a reliability analysis for a diagnostic test. MATERIALS AND METHODS: Sixty-three studies of diagnostic test accuracy (DTA) and 36 studies reporting reliability analyses published in the Korean Journal of Radiology between 2012 and 2016 were analyzed. Studies were judged using the methodological guidelines of the Radiological Society of North America-Quantitative Imaging Biomarkers Alliance (RSNA-QIBA), and COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) initiative. DTA studies were evaluated by nine editorial board members of the journal. Reliability studies were evaluated by study reviewers experienced with reliability analysis. RESULTS: Thirty-one (49.2%) of the 63 DTA studies did not include a reliability analysis when deemed necessary. Among the 36 reliability studies, proper statistical methods were used in all (5/5) studies dealing with dichotomous/nominal data, 46.7% (7/15) of studies dealing with ordinal data, and 95.2% (20/21) of studies dealing with continuous data. Statistical methods were described in sufficient detail regarding weighted kappa in 28.6% (2/7) of studies and regarding the model and assumptions of intraclass correlation coefficient in 35.3% (6/17) and 29.4% (5/17) of studies, respectively. Reliability parameters were used as if they were agreement parameters in 23.1% (3/13) of studies. Reproducibility and repeatability were used incorrectly in 20% (3/15) of studies. CONCLUSION: Greater attention to the importance of reporting reliability, thorough description of the related statistical methods, efforts not to neglect agreement parameters, and better use of relevant terminology is necessary.

The Hahn Pseudoisochromatic Plates were used to test the color sense of 100 color defective subjects. Results and data obtained from the test showed the plates to be practically useful in screening. qualitative and quantitative diagnostic test for congenital color defective subjects.

A simple diagnostic test has been performed for the evaluation of the patency of the lacrimal excretory system. A 1% Saccharine solution was instilled in the lower conjuctival cul-de-sac and then tastfd by the patknt when it reachd the oropharynx; this painless and effective test was performed in study using 100 subjects. The average time lapse between instillation and testing was 7 and 1/6 minutes. Of the 100 subjects, 46% had a positive taste response within 5 minutes, 79% within 10 minutes, 88% within 15 minutes, and 97% within 20 minutes.

Like any other medical technology or intervention, diagnostic tests should be thoroughly evaluated before their introduction into daily practice. Increasingly, decision makers, physicians, and other users of diagnostic tests request more than simple measures of a test's analytical or technical performance and diagnostic accuracy; they would also like to see testing lead to health benefits. In this last article of our series, we introduce the notion of clinical utility, which expresses-preferably in a quantitative form-to what extent diagnostic testing improves health outcomes relative to the current best alternative, which could be some other form of testing or no testing at all. In most cases, diagnostic tests improve patient outcomes by providing information that can be used to identify patients who will benefit from helpful downstream management actions, such as effective treatment in individuals with positive test results and no treatment for those with negative results. We describe how comparative randomized clinical trials can be used to estimate clinical utility. We contrast the definition of clinical utility with that of the personal utility of tests and markers. We show how diagnostic accuracy can be linked to clinical utility through an appropriate definition of the target condition in diagnostic-accuracy studies.
