ADAMTS13 Assays

University College London has asked Departments to stop providing external specialist referral assays.

We will therefore not be able to perform specialist haemostasis referral assays for ADAMTS13 after the end of this year.

In order to complete any outstanding assays on samples already received, we will not be able to accept any blood samples after Friday 14th December 2018.

I hope that you will be able to find an alternative referral laboratory (ADAMTS13 assays are available at

  • HSL Laboratories (UCLH),
  • St Thomas’ Hospital,
  • Royal Hallamshire Hospital Sheffield,
  • Queen Elizabeth Hospital Birmingham,
  • Leeds Royal Infirmary,
  • Bristol Royal Infirmary,
  • and other institutions.
