A considerable demand for convenient, rapid, inexpensive assays of ferritin in serum has been generated in recent years in hospital laboratories and blood banks. We describe a simple and rapid particle-enhanced turbidimetric immunoassay suitable for routine application in a Monarch 2000 centrifugal analyzer with commercially available reagents. This fully automated assay (y) requires no pretreatment of sample, and correlation with a two-step sandwich ELISA (x) is excellent (y = 1.018x + 0.397, Sy/x = 0.027). The analytical range extends from 5 to 900 micrograms/L. Intraassay imprecision (CV) ranged from 1.1% to 5% for various specimen concentrations. Interassay imprecision ranged from 2.2% for above-normal concentrations (755 micrograms/L) to 9.5% for low concentrations (39 micrograms/L). No specimen-related carryover was detected. The method has been useful in our predeposit autologous blood transfusion program for rapid assessment of iron status in patients undergoing repeated phlebotomies.
