[Study of thyroid function using diverse methods of separation of plasma radioiodine compounds in rats].
We compared the fractionations obtained by three different methods of dosage of thyroid hormones and we concluded that trichloracetic PBI is very rapid, (about 15 minutes) excluding the length of calculation of radio activity), is easy to execute, and uses inexpensive materials. Separation by exchanging resins of ions is also very rapid (15 min.), a little more precise, but the cost of operation is much higher. Separation by sephadex G25 is very time consuming (one day), and much more meticulous; its cost is equally high.
