Tryptase percentile

One of our customers using ImmunoCAP Tryptase has a question regarding the 99th percentile as there is only the 95th percentile in the DFU?

Referring to the study shown in our Dfu for Tryptase, the 99<sup>th</sup> upper percentile for healthy individuals is 14,8 µg/l. Except for the information that is present on page 2 in the Dfu we do not have any more official documents from this study available. Though this value is calculated from the same patient material as the values shown for geometric mean and 95<sup>th</sup> upper percentile.
