Abstract
Different methods for the determination of thyroid and related hormone have been reviewed. Performance characteristics of the radio isotopic method for the hormone assay were identified. Bound T3, Bound T4, TSH and Free T4 were assayed using different counting time and two different pulse height window levels. A very little difference was found during the measurement. The whole procedure was performed using Canberra AccuSpec NaI system, which has a high precision and stability. (c Squire equals to 3.56, detector resolution 9.10% and a 2k channel MCA). It is noticed that for low counting measurement counting time and window effect are present. It is assumed that for analog devices with single channel system the difference may be significant.
