A method is described for the automation of the T3-uptake test using a discrete analyser.
This enables 160 samples to be analysed in two hours at a cost of only 9p a sample. By
making use of a simple correction procedure for differences in charcoal contact time and for
radioactive carryover it is possible to get a within-batch precision of 2ˇ 5% and a between-
batch precision of 4ˇ 6% for values within the normal range.
