[Comparison of 2 different commercial kits for research on the rheumatoid factor with the Waaler-Rose method chosen as reference]. / Comparazione di due diversi kits commerciali per la ricerca del fattore reumatoide con il metodo Waaler-Rose scelto come riferimento.

Research was carried out on the rheumatoid factors in the serum of 917 patients by means of two tests (one using polystyrene and one with erythrocytes) and the results obtained were compared using a method of reference. The conclusions of this research allow us to affirm the necessity of using all three tests for the diagnosis of rheumatoid factor.
