Reference intervals

The Clinical biochemist. Reviews, 2010
Recommended elements of a process for establishing a reference interval: Define the analyte (measurand) for which the reference interval is being established, the clinical utility, biological variation and major variations in form. Define the method used, the accuracy base, and analytical specificity.

Reference interval and preanalytical properties of serum neurofilament light chain in Scandinavian adults

Scandinavian Journal of Clinical and Laboratory Investigation, 2020
The neurofilament light chain (NfL) is a promising biomarker of neuronal injury which is approaching routine clinical use. With the development of ultra-sensitive technologies, NfL has become measurable in the peripheral blood but the reference interval ...

Radiographic vertebral left atrial size: A reference interval study in healthy adult dogs.

Veterinary Radiology & Ultrasound, 2020
Thoracic radiography is a useful technique for the evaluation of cardiac dimensions, especially when echocardiography is not possible. The vertebral left atrial size (VLAS) has recently been proposed as a new radiographic method for quantifying left ...

Big data and reference intervals

Clinica Chimica Acta, 2022
Although reference intervals (RIs) play an important role in clinical diagnosis, there remain significant differences with respect to race, gender, age and geographic location. Accordingly, the Clinical Laboratory Standards Institute (CLSI) EP28-A3c has recommended that clinical laboratories establish RIs appropriate to their subject population ...

Reference Intervals in Coagulation Analysis

Hämostaseologie, 2022
AbstractBlood coagulation analysis is characterized by the application of a variety of materials, reagents, and analyzers for the determination of the same parameter, or analyte, by different laboratories worldwide. Accordingly, the application of common reference intervals, that, by definition, would represent a “range of values (of a certain analyte)

Reference intervals: an update

Clinica Chimica Acta, 2003
Reference intervals serve as the basis of laboratory testing and aid the physician in differentiating between the healthy and diseased patient. Standard methods for determining the reference interval are to define and obtain a healthy population of at least 120 individuals and use nonparametric estimates of the 95% reference interval.

Reference interval estimation of small sample sizes: A methodologic comparison using a computer-simulation study.

Veterinary clinical pathology, 2019
BACKGROUND According to the ASVCP and other guidelines, samples should comprise at least 120 individuals for reference interval (RI) estimation. Unfortunately, this minimum sample size is difficult to achieve in veterinary medicine.

Reference intervals: the way forward

Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 2009
New facts have recently enhanced interest in the topic of reference intervals. In particular, the International Organization for Standardization standard 15189, requesting that ‘biological reference intervals shall be periodically reviewed’, and the directive of the European Union on in vitro diagnostic medical devices asking manufacturers to provide ...

Reference interval determination for glycated albumin in defined subgroups of a South African population

Annals of Clinical Biochemistry, 2019
Background Glycated proteins, such as glycated haemoglobin (HbA1c) and glycated albumin (GA%), are increasingly being used for glycaemic control assessment and the diagnosis of diabetes mellitus. GA% is an intermediate marker of glycaemic control that is
