Rapid Diagnostic Centres

Under Review — this page was due to be reviewed by Tuesday, 10 May 2022. The information shown here may be outdated.

Rapid Diagnostic Centres (RDCs) offer a diagnostic pathway for all patients with non-specific symptoms that could indicate cancer. This patient cohort doesn’t necessarily fit the criteria for a referral onto a specific 2WW pathway.

Features and benefits:

  • provides a one-stop service where possible
  • a consultant led triage process that enhances the speed and efficiency of pathway
  • gives patients a clear diagnosis or onward management plan, in addition to tests that exclude/identify cancer
  • enables effective communication between primary and secondary care
  • enhanced support from clinicians, CNS and navigators
  • reduced need for GPs to make multiple cancer referrals when a cancer of unknown origin is suspected.

GPs should request a prescribed set of investigations and filter function tests (i.e. blood tests) when making a referral. These results should be included in a referral form, and should be recent (less than six months old). These tests can be ordered as a bundle on tQuest at North Middlesex, RFL and UCLH. It is also available on SunQuest at WH. GPs in the Whittington catchment can order tests on SunQuest before making a referral to the other three trusts.

Patient with a definite or almost definite diagnosis of metastatic disease should be referred to a CUP service. 

In future the RDC will take patients with a suspected myeloma who have non-specific symptoms.
