More accurate the better

When I have seen other members post a chimerism that was falling or rising, it was usually pretty precipitous in decline, and firmly upward when rising.
I think anytime you can have a more accurate test, it is to your advantage. I think that is the idea behind the test in this study. Their idea is a that a chimerism of less that 90% or one that is falling is indicative of a higher chance of relapse. If the test is more accurate, it would follow that the prognosis of relapse would be more accurate.
