Hi flossyboo,
Dr (now Professor) Quenby is now at Birmingham Heartlands Hospital and the NKC trial has moved there. Think that they are the only place in the UK doing the uterine biopsy test for the cells (understand that Mr Shehata and a number of other doctors do more general blood tests, which are yet more controversial).
When the clinical trial was in Liverpool there was no option to pay for the biopsy test, so only women who met the criteria for the clinical trial were able to have it. The criteria are published somewhere, think there is a link from the Miscarriage Association site, and include a maximum age and that no other reason must have been found for the recurrent m/c.
I understand from other ladies on another website, though, that once the test is done one can opt NOT to be in the clinical trial and, if the test indicated it, be prescribed the treatment by one's GP, who would refer to info from Dr Quenby.
Not sure what the arrangements will be in Birmingham, is probably worth ringing them up to find out.
Your GP can refer you directly and in parallel to Dr Quenby, no need to get a referral from a consultant.
