Triiodothyronine (T3) ELISA Kit

  • Created on the 26 January, 2017.


Thyroid hormones play essential roles in the proper development and differentiation of many cells within the human body. Triiodothyronine (T3) is a tyrosine-based hormone that is produced by the thyroid gland and is a useful marker for hyperthyroidism and hypothyroidism diagnosis. One of the major carrier of circulating thyroid hormones is thyroxine-binding globulin (TGB). There are a number of pathological and physiological stimuli that can influence thyroid hormone synthesis and any deficiencies or excess of thyroxine can cause many disorders. The level of T3 is found to be normal in individuals with euthyroid, whereas in hyperthyroid patients it is increased and in hypothyroid patients it is decreased.


Triiodothyronine ELISA kit can be used to reliably detect levels of total T3 present in serum or plasma samples. The detection sensitivity of this assay is 0.1 ng/ml.


This triiodothyronine ELISA kit has a minimum detectable sensitivity concentration of 0.1 ng/ml. The assay dynamic range for this kit was determined to be between 0.5 – 10 ng/l.

Your secretory IgA ELISA kit gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

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.

You are my first point of contact when I am looking to purchase ELISA kits. You have such an easy and simple system, yet it is very effective.
