Thanks for letting me know you are using the Natera/Signatera test. Yes, there was an opening at UCLA at the time. I just checked and they still show as "recruiting" for KRAS pancreatic tumors and KRAS/NRAS tumors at NIH. Have you tried calling the locations directly? That's what I did, but it took more than one call to talk with someone. I've found these types of facilities can be short staffed in terms of phone answering. Let us know how it works out for you.
