A new TSH assay. Just another technique or a useful test?
The immunoradiometric assay is a sensitive test for diagnosing thyroid dysfunction. It permits greater accuracy by measuring response of thyrotropin-producing cells of the pituitary to thyroxine (T4) as opposed to comparing circulating T4 to a range of values from healthy controls. The assay allows improved precision in establishing replacement and suppressive doses of hormone for thyroid disease.
