Progenika will provide blood group genotyping reference laboratory services to ARUP Laboratories, the firm said last week.

Salt Lake City-based ARUP will next month begin offering the service to determine patient red blood cell antigen profiles when serology has logistic and functional limitations.

Progenika's service uses the company's blood group genotyping microarray, which detects over 100 genetic variants in the nine blood group systems that are most relevant to transfusion safety, the firm said.

Randox Laboratories last week launched three biochips for the detection of a variety of antimicrobial agents.

The arrays enable multi-analyte testing of up to 12 antimicrobials from a single sample, Randox said. Its Antimicrobial Array I tests for sulphonamides, its Antimicrobial Array II for general antibiotics, and its Antimicrobial Array III tests for nitrofurans, chloramphenicol, and malachite green.

According to Randox, the included antimicrobials are used in human and veterinary medicine and their use in food producing animals could result in potentially harmful concentrations in tissue, organs, and milk.

Randox arrays are chemiluminescent enzyme-linked immunosorbant assays. The biochip contains an array of immobilized antibodies that are each specific to a different antimicrobial. The antimicrobial arrays are analyzed on the Crumlin, UK-based firm's semi-automated Evidence Investigator system.
