A radioimmunoassay procedure for luteinizing hormone in serum or plasma has been developed in which the assay mixture is incubated at 37 °C. for a total of 22 hours rather than at 4 °C. for 4 to 7 days. The within assay coefficients of variation for the 37 °C. and 4 °C. methods, respectively, are 8.5 per cent and 4.7 per cent, while the between assay variations are 17.0 per cent and 15.1 per cent. Values at 4 °C. (y) were related to values at 37 °C. (x) according to the equation x = 1.4y + 0.6 with a correlation coefficient of 0.86.
