Low and high are relative terms and completely meaningless without actual numbers. Consult your doctor to rule out other conditions, nothing here is actual medical advice.

High iron - is it UIBC, TIBC, ferritine? Lower wbc - what level, exactly? Diet doesn't affect leukocyte levels, it is important to rule out other conditions. And, again, creatinine, how high is it? Kidney function can be measured with creatinine, age and race factors. Urea is also important to know when talking about kidneys.
