Roche's is the only hs-cTnT assay in the US. Labs outside the US often use a single cutoff of 14 ng/L, and the IFCC table lists 9 ng/L for women and 17 ng/L for men for the assay version labeled outside the US. Older conventional (4th generation) tests report in ng/mL and have their own limits. The 99th percentile is the upper limit of what the assay sees in healthy people, not a diagnosis.
