The FDA has cleared Randox's Immunoassay Premium Plus quality control for use in US laboratories. A multi-analyte control, it combines 52 analytes, including tumor markers, hormones, therapeutic drugs, and Vitamin D. The combination of analytes contained within this assayed control enables labs to effectively quality control a range of immunoassay tests, reducing the number of single controls required, thereby saving time and money. The Acusera Immunoassay Premium Plus is manufactured from 100% high quality and highly screened human serum to help minimize antibody cross reactivity, reducing the possibility of lot-to-lot variations when changing control batches. An assayed control, instrument-specific target values for each analyte are assigned using data from a global peer-group of over 25,000 laboratories. Three levels of control are available with analytes present at clinically significant levels. This includes Ferritin and Vitamin B12 at levels suitable for anemia monitoring. The level 1 control contains ultra-low TSH levels. Lyophilized for enhanced stability, when reconstituted this control will remain stable for 7 days at +2-8ºC or 4 weeks at -20ºC.
