NORCROSS, Ga.--(BUSINESS WIRE)--Guided Therapeutics, Inc. (OTCBB & OTCQB: GTHP) today announced its operating results for the first quarter ended March 31, 2011. Service revenue for the first quarter of 2011 was $767,000, compared to $821,000 in the first quarter of 2010. The quarter over quarter variability is primarily due to the timing of the Konica Minolta Opto contract. The net loss available to common stockholders for the first quarter of 2011 was $726,000, or $0.02 per share, compared to a net loss available to common stockholders of $3.2 million, or $0.15 per share, in the comparable quarter of 2010. The loss amount reported for the first quarter of 2010 was due primarily to non-cash interest on debt and preferred stock dividends, both of which were converted to common stock.
