Mc. Marca et al., Evaluation of canine serum thyrotropin (TSH) concentration: comparison of three analytical procedures, J VET D INV, 13(2), 2001, pp. 106-110
A comparative study of 3 analytical methods (immunoradiometric assay, enzym
e immunometric assay, and chemiluminescent immunometric assay) for canine s
erum thyrotropin (TSH) was performed. Ninety-six dogs were included in the
study. The within- and between-run precision was evaluated for each method,
and correlations for the results obtained with each method were examined.
The best within- and between-run precision was obtained with the chemilumin
escent immunometric assay. Satisfactory correlations for the 3 analytical p
rocedures were obtained but varied in relation to serum TSH concentration.
