Are MRD tests and detection thresholds standardized across labs or is it important to complete MRD testing with the same lab each time?

So, is MRD testing standardized? And that's a good question. So not necessarily. Generally speaking, depending on where you have your MRD tested, there might be a slightly different platform that's used to do that. And so it's very difficult to compare MRD values across different institutions, across different laboratories. So in general, I recommend that once a specific MRD test is chosen for a specific patient and their type of leukemia, that that same test is used over the course of therapy to give more accurate comparisons of the results.
