I’ve donated blood since I was in high school.
The last time I tried I was turned away due to a hematocrit of 37 (minimum 38 to donate).
Today my hematocrit was 31. And that was after three tries to get the machine to read my blood sample.
I think it’s more likely a nutritional deficit, so I’m going to work on increasing protein intake and add iron supplements over the next few weeks.
A third strike and I’ll make a doctor’s appointment.
