Necessity of Routine Repeat Testing of Critical Values in Various Working Shifts
Background & Objective: Accurate and timely reporting of critical values is an important issue. There is some doubt whether repeat testing of critical values would offer any advantage over single testing or not. The aim of this study was evaluation of utility of routine repeat testing of critical values in our referral center and to compare probable variations in different work...
متن کاملSpatial Correlation Testing for Errors in Panel Data Regression Model
To investigate the spatial error correlation in panel regression models, various statistical hypothesizes and testings have been proposed. This paper, within introduction to spatial panel data regression model, existence of spatial error correlation and random effects is investigated by a joint Lagrange Multiplier test, which simultaneously tests their existence. For this purpose, joint Lagrang...
متن کاملOn Using Asymptotic Critical Values in Testing for Multivariate Normality
Many multivariate statistical methods call upon the assumption of multivariate normality. However, many researchers fail to test this assumption. This omission could be due either to ignorance of the existence of tests of multivariate normality or confusion about which test to use. Although at least 50 tests of multivariate normality exist, relatively little is known about the power of these pr...
متن کاملUtility of Repeat Testing of Critical Values
Context.—A common laboratory practice is to repeat critical values before reporting the test results to the clinical care provider. This may be an unnecessary step that delays the reporting of critical test results without adding value to the accuracy of the test result. Objectives.—To determine the proportions of repeated chemistry and hematology critical values that differ significantly from ...
متن کاملDoes routine repeat testing of critical laboratory values improve their accuracy?
Background: Routine repeat testing of critical laboratory values is very common these days to increase their accuracy and to avoid reporting false or infeasible results. We figure that repeat testing of critical laboratory values has any benefits or not. Methods : We examined 2233 repeated critical laboratory values in 13 different hematology and chemistry tests including: hemoglobin, white...
