Introduction: Iron is an important factor of the energy balance and correlates with serum ferritin. For competitive athletes, ferritin measurements are regularly performed at certified medical laboratories. However, as a laboratory change happened, we questioned the validity of ferritin levels, since unusually high values were measured. The aim of this study is to compare the ferritin values of blood samples in six different laboratories and to evaluate the diagnosis of iron deficiency.
Methods: Blood samples from 63 patients with suspected iron deficiency were sent to six laboratories for ferritin measurements.
