Troponin testing in suspected ACS patients at HEFT

The Trust guidance on Cardiac Troponin testing has been revised in line with the European Society of Cardiology guidance.

This process will be in place from 10th October 2016 and will be subject to audit. The trust uses gender specific Troponin results – for Males <34ng/l and for Females <16ng/l are considered to be within normal range.

The main change is that patients with chest pain >6hrs ago, and remaining pain free during their hospital attendance, will only require a single troponin in order to exclude an ACS. If the hs-TnI is undetectable, risk stratification is also favourable and the patient is pain free then the patient can be considered for discharge with arrangements for outpatient investigation if appropriate.

Paired troponin samples should still be sent at 0h and 3h for patients with onset of chest pain within the last 6 hrs or with ongoing chest pains whilst in hospital.

The ICE requesting system will incorporate a prompt box to ask clinicians to clearly specify if the request is for a single or paired troponin. There will also be a reminder message on the results screen of the Troponin results.

The flowchart below summarises this change and is a reminder of the role troponin plays in the suspected ACS pathway.
