What generation of TNT reagent was used in these papers? The generation 2 TNT did respond markedly to skeletal forms of TNT and the current generation 3 is more specific for cardiac TNT. In our experience with generation 3 TNT is the only false positive TNT results are from renal patients. cheers "We tortured the data until it confessed."

The suggestion made in at least one paper (Clin Chim Acta 2001; 306:27) is that this may be due to release of cTnT from skeletal muscle. Does anyone have any evidence to support or refute this suggestion or is this indeed the exception that proves the rule?
