Finally, those patients who were categorised as having anaemia of another cause or without evidence of iron deficiency (ferritin < 30 μg/L and CRP ≤ 5 mg/L, n = 18) had a similar median pre-infusion haemoglobin to those with anaemia of inflammation (110 mg/L, range 103 to 115). The gene discussed is CRP; the disease is nutritional disorder.
