Pharmacia Delfia

The requested name "Pharmacia Delfia" does not appear to be the exact legal name of a standalone company. The strongest evidence indicates it refers to Pharmacia, a historical Swedish pharmaceutical and biotechnology company, together with DELFIA, a branded time-resolved fluorescence immunoassay technology that originated under the Pharmacia/Pharmacia-LKB umbrella. Pharmacia operated in pharmaceuticals, biotechnology, and scientific instrumentation before a series of mergers, divestitures, and acquisitions. Its life-science tools activities were later associated with Pharmacia Biotech and then Amersham Pharmacia Biotech, while the DELFIA assay platform continues today as a branded assay technology sold by Revvity. Accordingly, the best interpretation is that "Pharmacia Delfia" is a historical brand/company reference rather than an exact current company name.
