hi bubba i found this so far:
Essentiality of copper in humans
American Journal of Clinical Nutrition, Vol 67, 952S-959S, Copyright © 1998 by The American Society for Clinical Nutrition, Inc
Diets in Western countries provide copper below or in the low range of the estimated safe and adequate daily dietary intake. Copper deficiency is usually the consequence of decreased copper stores at birth, inadequate dietary copper intake, poor absorption, elevated requirements induced by rapid growth, or increased copper losses. The most frequent clinical manifestations of copper deficiency are
anemia, neutropenia, and bone abnormalities.

The term neutropenia describes the situation where the number of neutrophils in the blood is too low
contains info on a bajillion types of neutropenia, including congenital and acquired types, with this tidbit related to nutrition:

Nutritional deficiencies include vitamin B-12, folate, and copper deficiency
.
i had a quick look at the B12 and folate side of things and am less certain that they are involved to the same degree as copper. i'd go to copper as a potential nutritional suspect first.
now to figure out how to evaluate a copper test result... what is a healthy copper level?:

Determination of copper levels in serum of healthy subjects by atomic absorption spectrometry
Abstract
Copper levels in serum samples of 84 healthy subjects living in southeastern Spain were determined using the flame atomic absorption spectrometry technique... Mean copper concentrations were 1.092 ± 0.365 mg/l (with the range 0.304–2.000 mg/l) and 1.113 ± 0.253 mg/l (corresponding to an interval of 0.648–1.760 mg/l) for women and men, respectively ... Estimated daily dietary intakes on copper in women and men were 1.38 and 2.10 mg Cu/day respectively.
looks like 1.100 mg/L might be a good target. i have other copper studies kicking around somewhere.. i'll dig them up and we can compare mean values in healthy people to see if there's general academic agreement on a 'sweet spot' inside the normal range.
so with all that said, you may wish to suggest a copper test. remember, if the test gets done, don't let them tell her it's normal! get the result including units, and we can see if it lines up with healthy subjects or not.
best wishes for your daughter, bubba
