The CV in the Abbott FPIA assays exceeded 20% only at the lowest concentrations of PCP and BEG tested.
Carter said that discontinuing the FPIA program will result in a one-time pre-tax charge to INCSTAR's second quarter earnings of approximately $3 million and that the company had spent approximately $7 million on the FPIA project over an 18-month period.
Moreover, because of poor protein binding of digoxin-like immunoreactive components of ginseng, elimination of this interference in the FPIA assay by monitoring free digoxin in the protein-free ultrafiltrate is not possible.
However, in Primavette samples Hcy obtained by FPIA was approximately 11% higher than Hcy obtained by HPLC.
3 million restructuring charge resulted from INCSTAR's decision, announced on May 17, 1994, not to further pursue commercialization of its FPIA automation technology, in favor of the company's ongoing strategic focus on the development and marketing of reagents that will work in an automated testing environment and run on existing instrumentation.
In addition to our continued work toward commercializing our FPIA automation technology, we are working on several other initiatives that we believe will better position us for growth.
Hcy levels were measured using automated FPIA immunoassay technology on an Abbott Diagnostics IMx immunoanalyzer.
