T4 Total ELISA Kit (Feline)

  • Created on the 29 August, 2018.

INTENDED USE

Feline T4 total ELISA kit is designed to detect quantitative levels of total thyroxine (T4 total)  using feline (cat) serum or plasma samples. The dynamic range for this assay is 50.0 – 250.0 nmol/l.

BACKGROUND

T4 (thyroxine) problems in cats can be identified through the following symptoms; polyphagia, polyuria, polydipsia, weight loss, cardiac disease, vomiting and hyperactivity. All of these symptoms are usually an indication of hyperthyroidism. However, cats are found to not lose their appetite and are also quite active even though they are displaying the above symptoms. In majority of cases (approx. 80%) there is an enlargement of one or even both thyroid lobes that can be found. The levels of T3 and T4 serum can be decreased using a number of different drugs such as: heparin, phenothiazines, glucocorticoids and androgens.

SENSITIVITY

The standard range of cat total thyroxine using current feline T4 total ELISA kit is 50.0 – 250.0 nmol/l. Please contact us for the protocol insert for more details.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA kit performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA kits from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
