Segment Reporting [Abstract]

SEGMENT INFORMATION

NOTE 10 — SEGMENT INFORMATION

Management has determined that the Company has two segments for financial reporting purposes:  the technology and strategic partnerships segment ("TSP") and the assays and related products segment ("ARP").  The accounting principles of the segments are the same as those described in the Summary of Significant Accounting Policies in the 2012 10-K.

Intersegment sales are recorded at fixed prices that approximate the prices charged to third party strategic partners and are not a measure of segment operating earnings. Intersegment sales of approximately $2.9 million and $3.3 million for the quarters ending June 30, 2013 and 2012, and $5.6 million and $5.7 million for the six months ended June 30, 2013 and 2012, respectively, have been eliminated upon consolidation.  Following is selected segment information for the periods indicated (in thousands):
