Multi-cancer early detection

Blood-based screening for circulating tumor DNA.

DiagnosticEvidence A0 providers documented

What happens

A blood draw screened for circulating tumour DNA and protein markers, intended to flag a cancer signal and predict its tissue of origin before symptoms appear.

How to read the result

Specificity in the published validation studies is high, so a positive result deserves serious follow-up. Sensitivity is much lower for early-stage disease, which is the stage the test is marketed for.

Where it stops

These tests are laboratory-developed and are not a substitute for guideline screening — mammography, colonoscopy, low-dose CT. No randomised trial has yet shown a mortality benefit, and a negative result is not an all-clear.

Before you book

Three questions to ask

  1. 01What is the sensitivity for stage I disease in the validation data?
  2. 02What is the diagnostic pathway if the result is positive?
  3. 03Which guideline screenings do I still need?
