SUMMARY A method is described for the measurement of testosterone in peripheral blood plasma by competitive protein binding, using a 1:80 dilution of human late-pregnancy plasma and Sephadex for separating protein-bound from unbound steroid. The reliability criteria were examined in detail for plasma from bulls and rams. Testosterone was measured with a high degree of accuracy, and with a precision of 4·9–7·9% in the concentration range of 4–24 ng/ml. The specificity of the method was checked by comparing it with a gas-chromatographic technique, and the agreement was good. The testosterone concentrations in the peripheral plasma of bulls and rams were found to range between 2 and 24 ng/ml.

25 Hydroxycholecalciferol

1. A competitive protein-binding assay for plasma 25-hydroxycholecalciferol was developed, using Sephadex LH-20 columns for the isolation of the sterol and a partially purified protein from rat serum as the binding protein. 2. The mean plasma 25-hydroxycholecalciferol in eighteen male and female normal volunteers was 38 ± SD 14 pmol/ml (15–2 ± 5–6 ng/ml). 3. Levels of 25-hydroxycholecalciferol in plasma of four male volunteers maintained for 2 months on a diet supplemented with 26·1 nmol (10 μg) of cholecalciferol a day were found to be significantly higher. 4. High correlation was established between plasma 25-hydroxycholecalciferol values obtained by the competitive protein-binding assay and values obtained by bioassay.
