Is your signatera able to detect all 16 assays? I've just started with this monitoring, and only got 8 assays from my original tumor biopsy. So its not ideal. Also, ca19 has always been pretty low. 174 and diagnosis, 450 at peak on ineffective chemo, then under 35 since December 2022. Seing an upward trend over the last 1.5 years from 11 to 27.
