If taken at a blood bank the 18.2 means nothing. Twice i did a proper lab work in the morning and then went to blood bank. Both time the blood bank reading was off by almost two points. But not consistently in same direction!
I've got another data point on this. I gave blood the other day and when they checked my hemoglobin with the finger test the result was 18.9 (!). A CBC taken a week before said my HBG was 17.1. Then I took a CBC again 4 days after the donation[1] and HGB was 15.6.
1. To make sure my HGB wasn't really 18.9 before the donation, which freaked me out a bit.
