Flashcards do conjunto (9)
- 1AnaemiaLow blood haemoglobin concentration
- 2MicrocyticSmall MCV
- 3MicrocyticFailure of haemoglobin synthesis
(hence smaller erthrocytes) - 4MicrocyticCaused by iron deficiency as a result of gradual blood loss
e.g. menstruation, GIT lesions or cancers and parasitic infection - 5NormocyticNormal MCV
- 6NormocyticRed blood cell production is normal, but is a result of acute blood loss.
- 7MacrocyticLarge MCV
- 8MacrocyticFailure in DNA synthesis and cell division (during erythropoeisis).
Folic acid (thymine synthesis) and Vit B12 are essential for division. - 9MacrocyticVit B12 deficiency: pernicious (gradual but harmful) anaemia
Folic acid deficiency: pregnancy
