RAMIREZ BENAVIDES, Ginés Fernando  e  OSORIO, José Henry. Free Tetraiodothyronine (FT₄) serum levels by electrochemiluminescence method in canines. Rev. Cient. (Maracaibo) [online]. 2009, vol.19, n.3, pp.238-241. ISSN 0798-2259.

The present study establishes references values for free Tetraiodotironine (FT₄) in canines using eletrochemiluminescence method. Blood samples from 180 canines divided in six groups of age (males and females), 30 animals for each group were used. Significant differences (P<0.0001) was found between age groups but not between sex groups. The canine average values for FT₄ using this technique were as follow: younger than 1 year of age , 9.9 - 11.7 ng/L; from 1 to 7 years of age, 8.1 - 11.7 ng/L; older than 7 years of age 7.4- 8.6 ng/L. The electrochemiluminiscence method for measuring FT₄ is valuable diagnostic tool in canine medicine.
