Agreement between capillary and venous lactate in emergency department patients: prospective observational study.

ABSTRACT:

Objectives

Capillary blood lactate testing with handheld analysers has great advantages to reduce the time needed for clinical decisions, and for extended use in the prehospital setting. We investigated the agreement of capillary lactate measured using handheld analysers (CL-Nova and CL-Scout+ measured by Nova and Lactate Scout+ analyzers) and the reference venous level assessed using a point-of-care testing (POCT) blood gas analyser (VL-Ref).

Design

A prospective observational study.

Setting

A university teaching hospital emergency department in Hong Kong.

Participants

Patients triaged as 'urgent' (Category 3 of a 5-point scale), aged ≥18 years during 2016 were eligible. 240 patients (mean age 69.9 years) were recruited.
