New Test Launched

• Cell-free or circulating tumour DNA (ctDNA) is tumor DNA circulating freely in the blood of a cancer patient.
• Originates from dying tumour cells and can be present in a wide range of cancers but at varying levels and mutant allele fractions.

clinical Utility

• Qualitative and quantitative testing of circulating cell free DNA (CCFDNA) can be applied for the management of malignant and benign neoplasms.
• Detecting circulating DNA in cancer patients may help develop a DNA profile for early stage diagnosis in malignancies.
• To look for resistance mutation T790M in EGFR positive patients.
• Address the tumor heterogeneity.

Benefits

• It is non invasive
• Can be a substitute for primary biopsy in sick patients
• Repeated blood samples are much easier to obtain
