A meta-Investigation of 14 reports showed that the specificity of the elevated troponin about the 99th percentile was substantially lowered in sufferers with CKD. It's essential to know Should the troponins are trending after some time in these sufferers.[73] The troponin concentrations in sufferers with CKD are generally steady, so an increase and fall of your troponin can be much more indicative of the cardiac reason for the elevated troponin.
