Reference Values: Are They Useful?

Clinics in Laboratory Medicine, 1984
To answer the question of whether reference values are useful in clinical decision-making, this article addresses the following major controversies: (1) Are reference subjects representative of the group from which they are selected? (2) To what extent should the process of collecting reference values be standardized and controlled?

Reference Values

Clinics in Chest Medicine
Interpretation of measured lung function values relies on reference equations to define the range of values that would be expected in otherwise healthy individuals. Reference equations for lung function can be interpreted in a way similar to pediatric growth charts and incorporate key anthropomorphic determinants of lung health: height, sex, and age ...

Intraindividual reference values

Clinical Chemistry and Laboratory Medicine (CCLM), 2004
AbstractWhen a biological quantity examination exhibits a high degree of individuality, developing a strategy for interpreting these values in an individual context can be a useful alternative. Time-series analysis is the appropriate statistical framework to build a model for explanation of the behaviour of laboratory information and to forecast future

Reference change values

Clinical Chemistry and Laboratory Medicine, 2012
AbstractReference change values (RCV) provide objective tools for assessment of the significance of differences in serial results from an individual. The concept is simple and the calculation easy, since all laboratories know their analytical imprecision ...

ECHOCARDIOGRAPHIC REFERENCE VALUES IN WHIPPETS

Veterinary Radiology & Ultrasound, 2007
The aim of the study was to establish reference echocardiographic values for whippets, to compare these values with previously published reference values for the general dog population, and to determine whether there is an influence of gender and breeding lines on echocardiographic measurements.

Electrocardiographic reference values in whippets

The Veterinary Journal, 2009
The aim of this study was to determine the electrocardiographic characteristics of whippets and to compare the results with published reference values for a general dog population. Electrocardiographic parameters from 105 healthy whippets were used to establish reference values for the breed.

Extended dynamometry: reference values

Journal of Hand Surgery (European Volume), 2018
Grip strength is used as a measure of capacity in disability and personal injury claims. Although seemingly an objective measure, it is widely recognized that it is fallible to the effects of sub-maximal effort. We have developed an extended test protocol that uses the five positions of a Jamar dynamometer.

The evolution of the reference value concept

Clinical Chemistry and Laboratory Medicine (CCLM), 2004
AbstractThis manuscript reviews the introduction of the concept of reference values, the corresponding philosophy, and subsequent recommendations reflecting the different subtopics of the field. The generally unrecognised phenomenon that laboratory results of the population tended to be lognormal instead of Gaussian attracted the attention of the ...

Setting reference values in trichology

International Journal of Dermatology, 2015
AbstractBackgroundIn clinical trichology, reference values are often arbitrary. The difficulty in setting them up depends mostly on the presence of the androgenetic alopecia (AGA) genotype in subjects with clinically unapparent forms. Prepubertal children, who lack 5α‐reductase (a real indicator of the AGA phenotype), might provide reference values ...

Subject-based reference values

Scandinavian Journal of Clinical and Laboratory Investigation, 1995
Medical decisions based on comparison with group-based reference value have often less than desired sensitivity to significant changes in the biochemical or physiological state of an individual under investigation. Subgrouping of the reference values according to sex, age, or other criteria does frequently not solve this problem. The better solution is
