diaDexus, Inc. reported unaudited earnings results for the first quarter ended March 31, 2015. For the quarter, the company reported net loss of $1 million for the first quarter of 2015 narrowed from the $4.1 million loss reported for the same quarter last year due to revenue growth from product sales and reduction of operating costs and expenses. Total revenues were $5.5 million compared to $5.4 million reported in the first quarter of 2014.

This increase was primarily the result of increased sales of the PLAC ELISA Test, partially offset by a decrease in service revenue. Loss from operations was $508,000 against $3,868,000 a year ago. Basic and diluted net loss per share was $0.02 against $0.07 a year ago.
