Using BGI's sequencing technology, the firms plan to commercialize Natera's Signatera test in China and to develop reproductive health tests in "select markets."

The ctDNA test will be covered for all US fee-for-service Medicare patients with advanced (Stage IIIB/IV) NSCLC who meet specific clinical criteria.

Data being presented at the upcoming AACR meeting show that Guardant's liquid biopsy test provided more accurate and rapid mutation detection than tissue genotyping.

The assay monitors mutations across a patient's genome and matches them to mutations found in a patient's resected tumor and in DNA in the bloodstream.

Researchers will first compare liquid with tissue-based tumor profiling before implementing it as a way to enroll patients into the targeted drug trials.

The company received Chinese regulatory approval for a lung cancer assay last year and plans to seek approval for a liquid biopsy test this year.

The effort will also help resolve open questions about liquid biopsy sequencing's validity in clinical practice in general.

In Nature this week: study of gene drive feasibility in lab mice, circulating tumor DNA from cerebrospinal fluid to track glioma progression, and more.

The researchers believe using cerebral spinal fluid will enable them to identify brain tumors with a higher sensitivity than with blood samples.

The firm's has expanded its ctDNA sequencing test to cover 17 genes, enough to provide a readout of microsatellite instability for guiding cancer immunotherapy use.
