Thyroid Stimulating Hormone (TSH) ELISA Kit

  • Created on the 2 February, 2017.


Thyroid stimulating hormone ELISA kit is a reliable quantitative procedure for measuring TSH (thyrotropin) in human serum samples. This assay has a sensitivity detection limit of 0.06 mIU/l.


Thyroid stimulating hormone (TSH) which is also sometimes called thyrotropin is a glycoprotein hormone that has a molecular weight of 28,000 Daltons and is secreted by the pituitary gland. The function of TSH is to regulate the synthesis and release of T3 and T4 by the thyroid gland. Thyroid stimulating hormone is composed of alpha and beta subunits, the alpha subunits are similar alpha subunits found in LH, FSH and hCG glycoprotein hormones alpha subunits whereas the beta is more specific and is different from one hormone to another. One of the most important maker in the diagnosis of thyroid disorders is the measurement of serum TSH levels, where elevated concentrations of TSH (thyrotropin) can be a good indicator for overt primary hypothyroidism and a decrease in the thyroid reserve levels. Additionally, determining the levels of TSH is equally helpful in differentiating secondary and tertiary hypothyroidism (hypothalamic) from the primary thyroid disease. The advent of immunoassays has provided laboratories with sufficient sensitivity to be able to differentiate hyperthyroidism from euthyroid population. The following thyroid stimulating hormone ELISA kit is a second-generation assay that is able to provide a tool that can offer a means for discriminating the hyperthyroid-euthyroid range.


The minimum sensitivity detection limit for TSH (thyrotropin) using current thyroid stimulating hormone ELISA kit was approximately 0.06 mIU/l. The dynamic range for this assay is between 0.25 – 15 mIU/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.
