Pre Analytical Variables And Types Of Biological Samples

Preanalytical Variables And Biological Variation Establishment of a quality manual addressing preanalytical variables is a prerequisite for implementing measures to recognize and control this crucial component of laboratory quality, which cannot be detected by traditional analytical quality control procedures. the preanalytical quality manual should address both patient and specimen variables. Introduction a large number of variables can potentially affect the results of a laboratory test and these can be divided into: pre analytical variables analytical variables post analytical variables there is increasing evidence that an awareness of the significance of the pre analytical variables that can potentially affect a lab test, will ensure the reliability of the final result.

Preanalytical Variables And Biological Variation Ppt Non biological variables involve sample collection, handling and transport to the laboratory. all of these variables can be controlled to minimize the effect they have on laboratory results. The current paper focusses on a number of preanalytical variables which can be critical for any medical biology examination: (1) sampling related variables (type of samples, collection of the. The pre pre analytical phase includes test request, patient identification, collection, and transport, while sample handling, aliquoting, secondary labeling, and centrifugation belong to pre analytical phase. for expository purposes, we will distinguish pre analytic problems into patient related variables and sample related variables. Widely acceptable recommendations, which are for optimal molecular assays associated with pre analytic variables, are limited. in this article, we have reviewed most of the important issues in sample handling from bed to bench before starting molecular tests, which can be used in diagnostic as well as research laboratories.

Controllable variables include physiologic variables such as posture, prolonged bed rest, exercise, physical fitness and training, circadian variation, and travel. diet, life style, stimulants, drugs, herbal preparations, and recreational drug ingestion are additional examples of variables that can be controlled. Relevance of pre analytical parameters for product verification and validation. overview of new european and international standards on sample pre analytics. discussion of challenges in complying with the regulation on in vitro diagnostic medical devices.
