The General Free Triiodothyronine (FT3) ELISA Kit is a reliable and accurate tool for measuring levels of free triiodothyronine in human serum, plasma, and cell culture supernatants. This kit boasts high sensitivity and specificity, ensuring precise and reproducible results for a variety of research applications.Free triiodothyronine, also known as FT3, is a critical thyroid hormone that plays a key role in regulating metabolism, growth, and development. Imbalances in FT3 levels can have significant effects on overall health and may be indicative of thyroid disorders such as hyperthyroidism or hypothyroidism.
With its easy-to-use format and rapid results, the General Free Triiodothyronine (FT3) ELISA Kit is an essential tool for researchers studying thyroid function and related conditions. Whether investigating thyroid dysfunction or monitoring hormone levels in patients, this kit provides a valuable resource for advancing our understanding of thyroid health.

Intra-assay Precision:
Intra-Assay: CV <10%. 3 samples with low, middle and high level the index were tested 20 times on one plate, respectively.
Inter-assay Precision:
Inter-Assay: CV <12%. 3 samples with low, middle and high level the index were tested on 3 different plates, 8 replicates in each plate.
Stability:
The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. Note:To minimize unnecessary influences on the performance, operation procedures and lab conditions, especially room temperature, air humidity, and incubator temperatures should be strictly regulated. It is also strongly suggested that the whole assay is performed by the same experimenter from the beginning to the end.
