US authorities have given their approval to Swiss pharmaceutical giant Roche to market its test which screens for cervical cancer.

It is the only FDA-approved cervical cancer screening test that identifies genotypes 16 and 18, the two most aggressive forms of the potentially-fatal virus, at the same time as other high-risk forms, the company said.
Roche estimates that more than 55 million cervical smear tests are carried out in the US every year.
Last week the firm reported a nine percent fall in its first-quarter sales compared with a year ago, hurt by a strong Swiss franc.
Revenues for the first three months of the year reached 11.1 billion francs ($12.5 billion dollars, 8.6 billion euros).
The Basel-based group confirmed its full-year target, with group sales expected to grow at "low single-digit rates in local currencies."
