【Test Purpose】
T4 is the main product of thyroid secretion, and it is also an indispensable component of
the integrity of the hypothalamic-anterior pituitary-thyroid regulatory system. It
increases the basal metabolic rate and plays an important role in the development of all
body cells. T4 is stored in thyroid follicles in combination with thyroglobulin, and
secreted and released under the regulation of TSH. More than 99% of T4 in serum exists
in the form of binding to other proteins.
Testing for total T4 in a blood sample can tell if your thyroid is functioning abnormally.
【Detection principle】
This product uses fluorescence immunochromatography to quantitatively detect the
content of cTT4 in cat serum/plasma. Basic principle: T and C lines are marked on the
nitrocellulose membrane, the T line is coated with cTT4 antigen a, and the binding pad is
sprayed with a fluorescent nanomaterial labeled antibody b that can specifically
recognize cTT4. The cTT4 in the sample is first labeled with the nanomaterial. The
antibody b binds to form a complex, and then chromatographs upward. The complex
competes with T-line antigen a and cannot be captured; On the contrary, when there is no
cTT4 in the sample, antibody b binds to antigen a. When the excitation light is irradiated,
the nano material emits a fluorescent signal, and the strength of the signal is inversely
proportional to the concentration of cTT4 in the sample.
