Product news

Quidel Corporation has announced that it has received FDA clearance for the sale of its next generation immunoassay analyzers. The Sofia analyzer and Sofia Influenza A+B Fluorescence Immunoassay (FIA), combine unique software and fluorescent chemistry to give automatic and objective results.

The Sofia FIA employs advanced lateral flow and Immunofluorescence technologies to provide enhanced clinical sensitivity for influenza A and B. The Sofia Analyzer can accommodate both large and small laboratories using different operational modes, and additional features enable its use in a variety of healthcare settings, from hospitals to small clinics.

"We are very pleased with the FDA clearance of our Sofia Analyzer and Sofia Influenza A+B FIA," said Douglas Bryant, president and chief executive officer of Quidel Corporation. "This announcement represents the achievement of a significant milestone, and positions us in the marketplace with a strategically important platform that will provide numerous benefits to healthcare providers and their patients."

The Sofia Influenza A+B FIA is the first in a series of new Quidel FIA’s which will be available for the diagnosis of infectious disease as well as other conditions and disorders, using the Sofia Analyzer. The FDA clearance grants Quidel permission to sell both the Sofia Analyzer and the Sofia Influenza A+B FIA in the United States in advance of the upcoming influenza and respiratory disease season. Both the Sofia Analyzer and the Sofia Influenza A+B FIA received the CE Mark in August 2011, and are thus already available for sale in Europe and other ex-U.S. locations, and they are now available for commercial distribution in the United States.

ImmunologyImmunological techniques measure and characterize immune responses. Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.Point-of-CarePoint-of-Care Testing (POCT) or Near Patient Testing (NPT) products are available for urine, blood and other clinical chemistry analyses. POCT includes: blood glucose testing, blood gas and electrolytes analysis, rapid coagulation testing (PT / INR), rapid cardiac markers diagnostics, drugs of abuse screening, urine strips testing, pregnancy testing, fecal occult blood analysis, food pathogens screening, hemoglobin diagnostics, infectious disease testing and cholesterol screening.Clinical ChemistryBiochemistry (or clinical chemistry) involves the analysis of bodily fluids using chemical tests. Techniques used include HPLC, chromatography, spectroscopy, mass spectrometry, immunochemical, electrophoresis, turbidometric / spectrophotometric assay, MRI and ISE analysis. Tests are often carried out on plasma or serum but urine (urinalysis) and fecal specimens are also processed.Clinical MicrobiologyMicrobiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments.
