I will
reply as a laboratorian. I am not a MD or Pathologist.
From my experience
the biggest issue is lack of commutable cutoff’s. This poses difficulty when
the patient is transferred from the chest pain center to an in patient and the
troponin is switched from POC to lab based method. On approach is to add to the
lab report the method and ranges yet this is not a 100% mitigation. Other
issues to face are that POC usually lack the low end 10% CV goals precision of lab
based platforms such as Beckman Accu Troponin I, Abbott TnI ADV, and Vitros
Troponin I ES

Two queries today!
We have recently changed
to a more sensitive Troponin I assay within the laboratory but there has been a
request to look at offering a point of care Troponin assay within the emergency
department. We have been pointing out the potentail pitfalls of having two
differenet assays but would like to gather further evidence for and against.
I recognise that this is
a similar question to one posed recently but what are the experiences (
positive and negative) of labs and clinicians who have been running two
different troponin assays (be it two troponin I assays or a troponin I /
Troponin T combination) ?
Many thanks
Chris
