The story of a little girl suffering an apparent autoimmune “Iron deficiency” syndrome. This class of iron deficiency typically has had particularly high prevalence rates amongst women. However, it has recently been uncovered that traditional methods used for testing iron levels are crude and unreliable. Moreover, no attempt to improve or upgrade methodology has been made since testing first began centuries ago. Dr Heise from the Barely There Institute of Australia says “Relying on these archaic measuring systems has led to a skewing of results towards a false negative bias in women, thereby overestimating deficiency rates in women”. Turns out the girl and many like her had plenty enough iron all along.
