SPURIOUS HYPERKALAEMIA.

Abstract

In a patient with acute lymphoblastic leukaemia, the plasma was found to have a potassium level of 10.4 mEq./1. Investigations showed that plasma from patients with leukaemia may be found to have falsely high potassium levels because of breakdown of leucocytes between the venepuncture and separation of the plasma.

Integration of data derived from biological variation into the quality management system.

BACKGROUND: [corrected] Data on within- and between-subject biological variation are available for around 250 analytes commonly used in medical laboratories. METHODS: Integration of this data into the quality system occurs at all three levels of laboratory activity: (a) Preanalytic process: biological variation provides the basis for selecting the most appropriate specimen for analysis, for defining sample stability and for deciding suitable timing between samplings; (b) analytic process: biological variation-derived goals are fundamental for designing internal quality control procedures, and for evaluating laboratory performance; and (c) postanalytic process: delta checks based on within-subject biological variation values are used for validating results and for interpreting serial results from a patient. CONCLUSION: The biological variation is a pillar for managing quality in laboratory medicine.

Exponential increase in clinical use of plasma brain natriuretic peptide (BNP) assays.

AIMS: To document the number of requests by clinicians for plasma brain natriuretic peptide (BNP) measurements and to define which groups of practitioners have made use of the assay over the 7 years since it became available for clinical use. METHODS: We reviewed the number and source of requests by clinicians for measurements of plasma BNP in the Christchurch area (from 1995--when the assay became available, until July 2002). RESULTS: There was an exponential increase in requests for BNP measurements over the 7-year period (1995-2002). Of the 11,308 samples analysed, 47% came from hospital inpatients, 25.9% from patients in general practice, and 14% from hospital emergency departments. CONCLUSIONS: There has been a rapidly increasing uptake of the assay for plasma BNP by both hospital and primary care clinicians in the Christchurch area.
