| pubmed-article:473309 | pubmed:abstractText | The influence of malaria on HbA2 levels was investigated in two groups of children aged two to nine years from the Mano tribe of northern Liberia. One group, 174 children living in a town where there is malaria control, had a parasite rate of 6.5%, only a few having palpable spleens, but 282 children living in an area of intense malaria transmission had a parasite rate of 92%. All but one child in this group had enlarged spleens. However, the difference in proportions of elevated HbA2 values within the limits for beta-thalassaemia, 8% and 10.3% respectively, was not statistically significant (0.5 greater than P greater than 0.1). It was concluded that the influence of malaria on HbA2 levels is not significant and that this parameter is valid for detecting beta-thalassaemia trait in this population. Further, iron deficiency may be a more important factor than malaria to consider when assessing the results of HbA2 estimations. | lld:pubmed |
