[Measurement of triiodothyronine in urine].

A radioimmunoassay procedure to measure triiodothyronine (T3) in unextracted urine is described. One hundred microliter of T3 standards or samples were incubated with 100 microliter of T3 antiserum (1:40,000), 100 microliter of tracer 125I-T3 and 700 microliter of 0.05 M borate buffer, pH 8.6. Separation of free from bound antigen was achieved by dextran coated charcoal. The cross-reaction of L...
