BullnBear, found something interesting regarding a clinical trial being performed via Obstetrix Medical Group.
I believe, using you as a sounding board, that this clinical trial re-review, may help build the premise for the abstract of "Incidental detection of cancer with a non-invasive prenatal test (NIPT)".
They could use that older MT21! sample data and review for cancer markers, with access to the sample providers (mommies) for validation.
Just thinking out loud.
