Oncocount RGCC detects the presence of circulating tumour cells (CTCs) and their concentration in the blood. CTCs are a powerful biomarker, and their presence in the blood can act as an early warning sign that cancer is returning.

The test is designed as a follow-up test for patients who have cancer and are worried about the disease returning. Clinicians can use the Oncocount RGCC test to assess how effective cancer treatment is and the likelihood of cancer returning (relapse).
