Anti-TSH Receptor Antibodies (TRAb) ELISA Kit

  • Created on the 2 February, 2017.


This anti-TSH receptor antibodies ELISA kit is a reliable quantitative procedure for measuring TSH (thyrotropin) receptor auto-antibodies (TRAb) in human serum. The minimum sensitivity limit of this assay is 0.55 U/L.


TSH receptor auotoantibodies (TRAb) are found to be predominantly located on the surfaces of thyroid epithelial cells, these are essentially autoantibodies that are directed against TSH receptors. They are particularly useful in helping to distinguish between Graves’ disease and postpartum thyroiditis. In many cases they can also be used to determine the likely risk of neonatal/foetal thyrotoxicosis. During pregnancy TRAb are able cross the placenta and in many instances affect the foetal thyroid. In these cases a positive test for TRAb can be used to alert the obstetrician of potential risks associated to the baby during the neonatal period, such as thyroid dysfunction in the offspring. Anti-TSH receptor antibodies ELISA kit is often used as a diagnostic biomarker for many clinical applications.


The minimum sensitivity detection limit of anti-thyrotropin receptor auto-antibodies (TRAb) using current anti-TSH receptor antibodies ELISA kit is 0.55 U/L. The dynamic range for this assay is 1.0 – 40.0 U/L (WHO).

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.
