| pubmed-article:137034 | pubmed:abstractText | A radioimmunoassay for urinary tetrahydroaldosterone is described. An antiserum, elicited by a 3-carboxy-methyloxime 18-21 aldosterone diacetate conjugated to bovine serumalbumine, with which tetrahydroaldosterone cross reacts, is used. The method is specific, sensitive (10 pg/tube), accurate, reproducible (7%), thus allowing sufficient reliability for clinical applications. In 19 normal adults subjects under unrestricted sodium intake, the urinary tetrahydroaldosterone averaged 59,8+/-29,4 mug/24 h. | lld:pubmed |
