Development of an assay for human growth hormone in urine using commercially available reagents.
An assay for the measurement of human growth hormone in urine (u-HGH) has been developed using commercially available reagents and its analytical variables have been investigated. The procedure is sensitive to 0.50 muU/L urine, has an interassay precision of 6.2-7.5 (CV%) over the standard curve, and shows good parallelism and recovery. Urine samples for the assay can be collected in plain plastic bottles, stored at room temperature for up to 24 h and, after adding preservative, at -20 C before assay for three months. There was a good correlation between the responses of HGH in serum and in urine during clonidine and insulin stimulation tests.
