 Re:  Cortisol, TSH, free T4, free T3, B12, Folate, Ferritin, Oestradiol, Troponin and HCG


Following the implementation of a new analyser module, the above tests are validated assays but currently not UKAS accredited. 

Good analytical performance standards have been confirmed, but we are required to inform you that the United Kingdom

Accreditation Service (UKAS) has not yet re-accredited these tests.

This notice will remain in force until accreditation is granted.  There has been no change in the analytical quality of the results.
