New cancer detector that’s 10 times more sensitive than current methods could pave way for at-home testing
A new method of blood testing has proven up to 10 times as sensitive as current methods in detecting the presence of cancer, potentially paving the way for at-home pin-prick tests to monitor patients.
New research led by the University of Cambridge explored a new method of personalized genetic testing of tumors that can determine the success of an ongoing course of treatment as well as the likelihood of a future relapse.
Using the method, doctors can sift through blood samples for hundreds of different genetic mutations in the DNA released by the tumor into the bloodstream.
Strides in data analysis have also improved the clarity of the information that can be collected from a sample. This has further refined the technique and allows it to deliver remarkable testing sensitivity that can detect one mutant DNA molecule among a million, representing a 10-fold improvement on current methods.
