We offer a TPMT activity assay service to UK laboratories and also take referrals from outside the UK. Our TPMT assay carries the CE mark and has been
registered with the MHRA.  Deficient results are confirmed in our DNA laboratory.
We provide a service rather than an assay. We have clear policies for analysing samples for genotype - for example any patient details where an indication
that blood products have already been given is analysed for TPMT activity and also genotype studies. We continue to invest in this service to enable us to
meet demand and keep to our 1 day turn round, electronic reporting is available.
