I try not to, too-often, write blogs solely for subscription-only information, but this one merits it. Genomeweb publishes an extensive survey of users of MRD testing for solid tumors. The article is written by Molika Ashford. Find it here:
Extensive information and charts. Topics include which types of MRD testing are familiar, what brands are most familiar, what applications do you believe are most useful, do you perform MRD testing in-house, what commercial lab do you use, etc.
