Using a quick bedside lactate test to improve prioritization for patients triaged as yellow by the Manchester system
Official title: Impact of Point-of-care Lactate Testing as Triage Supplement on Patient Management Using Manchester Triage System
Run by University Medical Centre Maribor · NCT07123857 · Data updated 2026-11-12
This trial will test whether adding a rapid bedside blood lactate test helps emergency staff better prioritize care for patients assigned the yellow Manchester triage category.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are consenting patients who arrive at the emergency department and are assigned the yellow Manchester triage category, excluding pregnant patients, trauma cases, those with seizures, or patients who received prehospital adrenergic therapy.
✕Probably not a fit
Patients in other triage categories, pregnant patients, trauma patients, those with epileptic seizures, or those who received prehospital adrenergic therapy would not be eligible and are unlikely to benefit from this intervention.

What this trial studies
This is a prospective, randomized trial that enrolls adult patients placed in the yellow category by the Manchester Triage System at the University Medical Center Maribor. Enrolled patients will be randomized to standard triage versus triage supplemented with a point-of-care lactate measurement and possible re-triage based on the result. The trial excludes pregnant patients, trauma cases, patients with epileptic seizures, and those who received adrenergic therapy in the prehospital setting. Outcomes focus on changes in patient management and identification of higher-risk patients within the yellow category.
Why it matters
Potential benefit: If successful, the approach could identify higher-risk patients earlier within the yellow category and reduce under-triage and unsafe delays.
How similar studies have gone: Observational and ED studies have shown that elevated lactate is linked to higher mortality and can aid risk stratification, but randomized evidence specifically using point-of-care lactate as a routine triage supplement is limited.
