Anemia diagnostic flow-chart. This anemia diagnostic flow-chart is presented as a guide. Asterisk: Hepcidin is not yet available in routine clinical practice. Hash: WHO defines folate deficiency as serum folate < 10 nmol/L (4.4 g/L) or red blood cell folate, reflecting long-term status and tissue reserves, < 305 nmol/L (< 140 µg/L). Serum vitamin B12 < 150 pmol/L (< 203 ng/L) indicates vitamin B12 deficiency and a higher level does not exclude vitamin B12 deficiency, in which case blood methylmalonic acid must be assayed (a level > 271 nmol/L is in favour of vitamin B12 deficiency)
