Turbidimetry and radial immunodiffusion techniques are compared for measuring the average amounts of IgG in serum from healthy sheep, swine and chickens using different rabbit antisera. The correlation coefficients (r) between the IgG values measured by the two techniques, were high; r greater than 0.97. Turbidimetric measurement was found to be a reliable, rapid and simple method for IgG determination in serum.
