4.3.3. Investigation of Serum Iron Metabolism Parameters
The routine parameters of iron metabolism in serum were analyzed in a medical diagnostic laboratory. The concentrations of ferritin and transferrin were determined using an immunoturbidimetric method on the Cobas 8000 analyzer (Roche, Indianapolis, IN, USA). The concentration of iron in the tested samples was measured using a colorimetric method on the Cobas 8000 analyzer (Roche, Indianapolis, IN, USA).
