No, they aren't talking about a creamatocrit. I believe they are wondering 
about the electrolyte levels, sodium, potassium and such.

I think I know the baby that they are talking about, as we had a 2week old 
who had lost from 7#2oz @ birth to 4#14 oz when she went for her 2 wk 
check with peds. She was not jaundiced. She was hospitalized for severe 
dehydration, IV was started, Mother's milk seemed to be in well, she obtained 
4oz when pumping, I did pre & post nursing wts, which reveiled she was 
getting 2 1/2-3 oz per feeding, but she cont. to loose wt & her electrolytes 
were way off from normal. We ended up air-evacing her to Ark Children's 
hospital. The neonatal nurse who came for the transport mentioned she had 
seen this once before and it had been found to be that the mother's breastmilk 
was not adequatly supporting the baby. Of course as an IBCLC I have a lot of 
questions about that.

Thanks for everyones input.
Pam
