Recombinant Human TSH Stimulation Test

This information explains your recombinant human thyroid stimulating hormone (TSH) stimulation test. 

Thyroglobulin is a protein in your blood that is produced only by thyroid cells. We measure your thyroglobulin level to help us monitor your cancer after treatment. If your thyroglobulin level rises, it could mean that you need more tests and follow-up care to be sure your cancer has not returned.

Recombinant human TSH is given to stimulate any potentially remaining thyroid cancer cells. This will cause your thyroglobulin levels to go up if there are any thyroid cells left in your body.

For more information on blood tests that measure how your thyroid is working, read the resource Thyroid Function Tests. You can search for it on mskcc.org/pe or ask your nurse for it.

Testing Schedule

  • On day 1, you will have a blood draw to measure the amount of thyroglobulin in your blood at baseline.
  • Also on day 1, you will get an injection of  recombinant human TSH.
  • On day 2, you will get another injection of recombinant human TSH .
  • On day 5, you will have another blood draw. This is done to measure the amount of thyroglobulin in your blood after taking the recombinant human TSH.
