Study Notes
Investigating Nutritional Anaemias
- Nutritional anaemia results from deficiencies in nutrients essential for blood cell production.
- Haematinics are nutrients needed by the haematopoietic tissue to produce blood cells.
- Common haematinics include iron, vitamin B12 (cobalamin), and folate.
- Iron measurements include ferritin, transferrin, and transferrin saturation.
- Cobalamin is also known as vitamin B12.
- Folate, also known as vitamin B9.
- Other B vitamins (B2, B3, B6) are also involved.
- Vitamin A, Vitamin C, Vitamin E, Copper (through Hephaestin and ceruloplasmin), and Cobalt are also considered essential in blood cell production.
- Haematinic measurements help identify nutritional anaemias. However, these measurements can lack the sensitivity and specificity for a definitive diagnosis.
- Additional tests are often required to confirm diagnosis.
- Complete Blood Count (FBC) and blood cell morphology are important considerations before haematinic measurements.
- Haematinic treatments can promote reticulocyte response, increase haemoglobin concentrations, resolve cytopenias, and correct/partially correct clinically relevant symptoms.
- Nutritional anaemias are often associated with microcytic or macrocytic blood pictures, although this isn't always the case.
- Haematinic measurements may be performed in haematology or biochemistry laboratories, depending on the lab's structure.
