Digesting acquisitions can be a slow process - 18-24 months seems about average - and International Murex Technologies Corp. appears to have just about completed the task of digesting its February 1992 acquisition of Wellcome Diagnostics.

Year-end results for the Norcross, Ga.-based diagnostics company put it in the black for the first time since the acquisition, with net income of $2.7 million (16 cents per share) versus a loss of $17.6 million ($1.17) in 1992, despite adverse movements in exchange rates.

Much of the credit for the turnaround goes to President and COO David Tholen, who joined MXX in June 1993 after 21 years at Abbott Laboratories.
