ctDNA is a type of genomic testing. It uses a blood sample, collected in the same way as a standard blood test. Because of this, it's sometimes called a ‘liquid biopsy’.
ctDNA is showing promising results in finding and monitoring blood cancers. However, it is still an experimental test, which means we are continuing to research its effectiveness. Our hope is that by developing ctDNA, we can help people with blood cancer avoid painful biopsies.
How does ctDNA work?
Cancer tumours release tiny bits of DNA in your blood. A ctDNA blood test finds and analyses this DNA from the tumour. It may help us find out:
- more about the cancer’s characteristics – or ‘personality’
- more gene mutations to tell us how you might react to treatment
- which treatments are likely to be successful
- if the cancer is indolent or aggressive
- how you are responding to cancer treatment
- if cancer has returned after remission (a relapse)
- more about cancer to help with research in the future.
