I am worried that there is some confusion in the eyes (heads) of some
colleagues perhaps within and without the laboratory.
I understood the cutoff value for Troponin to be :
Troponin T 0.1 ng/mL or 0.1 µg/L with assay sensitivity ca.
0.01
Troponin I 1 ng/mL or 1 µg/L with assay sensitivity ca 0.1
We should not allow our results to be too cleverly reported for our
clinician customers to make silly mistakes.
It is essential for our clinician colleagues to be aware of the assay which
is on offer and its reference values (as with any assay, I hope)
I have seen 'eminent' papers quoting generic troponin levels without
reference to either troponin flavour or limits and I hope not too many of
our laboratory colleagues have either eggy faces or brown trousers !
please let me know if I am wrong !
With best wishes

Subject: Re: Troponin I units
Clinicians rarely mention or remember units of tests
in general. For example they say the patient had a
high TSH of 60 or a troponin I of 85 ...etc. There
seems to be an international consensus, albeit
unintentional, to use ug/L for troponins and therefore
we should use it. The argument of making high errors
with decimals is questionable.
