Hello, I wonder if anyone is able to help with a reference or supporting
literature for this test, which is said to distinguish between maternal and
fetal blood in stool or vomit?
It involves making a hemolysate with 5 vol of water, adding 1% NaOH and
looking for a pink-to-yellow/brown color change (indicates maternal) or no
change (indicates fetal).
Our paediatricians are keen to have it done 24/7, and I would like to get
more information about it.
