Screening for deficiencies of iron, B12, and folate was generally low, with limited testing for serum ferritin (33.7%), TSAT and serum iron (11.2% each), and vitamin B12 and folate levels (19.8% and 17.6%, respectively) with CRP measurements available for 21.0% of patients with anaemia. The gene discussed is CRP; the disease is anemia (phenotype).
