I used to donate as a Boy Scout and they would take a drop and put it in this solution and it had to sink if it did you could donate that was it mind you this was the late/mid 90sAt least the places around here only check your hemoglobin with their finger prick device similar to a glucometer. I have never had them pull blood and test actual iron and ferritin.
