Abstract: | Background Developing countries have high prevalence of diseases, but facilities to diagnose and treat them are limited. We must use
available resources in ways not needed where there are sophisticated equipment and trained staff. Anaemia is common; iron
deficiency affects health and productivity; folate deficiency in pregnant women causes foetal abnormalities. Few developing
countries can measure serum folate or ferritin, but standard automated blood analyses are widely available and can help predict
folate and iron deficiency. The RDW-CV% (coefficient of variation of the red cell width) measures the variability in the size
of red blood cells (RBC) in routine automated analysis of blood cells, but is seldom reported. Levels of RDW-CV% and haemoglobin
(Hb) can predict iron deficiency anaemia. |
