Two-site immunoradiometric assay for human parathyrin (PTH1-84) is specific for the intact, secreted, biologically active 84 amino peptide. This system incorporates two-different polyclonal antibodies to human intact PTH and has several technical advantages for use. This assay could detect a wide range of PTH in patients with hypo-, hyperparathyroidism,(More)
A newly established double antibody radioimmunoassay (RIA) was fundamentally and clinically evaluated. Original procedures were partially modified as follows: Sample volume for serum and urine was changed to 25 microliters, and thus 200 mg/l of alpha 1-m standard was prepared using 50 microliters of original standard solution (100 mg/l). The results were(More)
We studied on the basic performance of a non-extraction coated tube RIA kit, DPC Aldosterone kit (Nippon DPC Corporation). 1. The average binding CVs of the calibrators (25 to 1,200 pg/ml) were stable in a range from 1.4 to 1.9%. 2. The minimum sensitivity was 17 pg/ml from 2SD method of 0 calibrator. 3. The intra-assay reproducibility test showed an(More)
