Rapid Diagnostic Service

Definition/Description

This pathway exists for patients who are considered to have vague, non-specific, symptoms. Provided minimum referral criteria is met patients will receive chest x-ray and abdominopelvic ultrasound as a minimum. 

Red Flag Symptoms

Any patient with specific alarm symptoms warranting referral onto site-specific two week wait pathway should NOT be referred along the RDS pathway (in line with NG12). With the exception that patients who test FIT positive can be referred to RDS if there are additional vague symptoms present. 

DO NOT REFER

  • Patient has specific alarm symptoms warranting referral onto site-specific two week wait pathway (in line with NG12)
  • Patient is too unwell or unable to attend as an outpatient or needs acute admission
  • Patient is likely to have a non-cancer diagnosis suitable for another specialist pathway
  • Patient is currently being investigated for the same problem by another specialist team

Guidelines on Management

It is recommended the following filter function tests are carried out in primary care, where relevant for patients, to make a successful referral into RDS.

Core tests for patients with non-specific symptoms:

  • Urine dip for haematuria
  • FIT test (This is hugely important to avoid duplication of tests as if >10 will need colorectal 2ww referral and either CT virtual or optical colonoscopy. Abdominal CT in the community is therefore not required and will be a wasted appointment.
  • FBC, CRP, U&Es, LFTs, TFTs, HBA1c, CA-19.9

CA-125 and PSA if appropriate.
