More nucleic acid amplification test usage is ultimately good for patients, hospitals, and the MDx industry, according to a maker of the most widely used assay.

The offering raised net proceeds of $6.2 million, which will be used for working capital and general corporate purposes, the firm said. 

The results also suggest the cfDNA assay has high sensitivity and 100 percent specificity, comparable to other technologies being developed for liquid biopsy testing.

Tests in development for the Alere q include HIV, tuberculosis, and Ebola assays, and it will initially be targeted to low-resource settings in the developing world.

The Singapore-based molecular diagnostics firm continues to operate under court supervision while its finances get sorted out.
