PerkinElmer has announced the launch of a dry blood spot (DBS) based test for SARS-CoV-2 IgG using its GSP®/DELFIA® platform, which enables the processing of up to 5,000 samples per day. The finger-prick sample collection device allows for both decentralized sample collection and high-throughput testing. The product is being marketed as a CE-IVD test, and the Company plans to apply for Emergency Use Authorization (EUA) with the U.S. Food and Drug Administration (FDA).

Serological tests detect antibodies that are formed after an immune reaction to the pathogen has taken place. These tests can determine if an individual has developed immunity to a virus. Researchers are still studying how long antibodies last and whether they are protective against the COVID-19 virus.

The DBS assay is run on PerkinElmer’s GSP analyzer, a fully automated and high throughput system for large population testing. The GSP combined with the universal TRF (time resolved fluorescence) of the DELFIA platform screens more than 30 percent of all newborn babies worldwide, spanning 32 countries. The traceable DBS workflow consists of five main elements: sample collection, punching, measurement on the GSP analyzer, reagents, and software, to detect anti-SARS-CoV-2 IgG antibodies. The SARS-CoV-2 IgG assay can also be run with serum or plasma samples via the Company’s Victor2™D platform. With an install base of over 2,500 GSP and Victor2D instruments, the capability for laboratories to meet heightened demand for COVID-19 testing is robust.

“Dried blood spot samples have been used in large scale population screening programs for decades and can help alleviate the costs and logistical constraints associated with collecting, transporting and processing venous blood for SARS-CoV-2 antibody testing,” said Masoud Toloue, Ph.D., Vice President and General Manager, Diagnostics, PerkinElmer. “This CE-IVD marked assay enables decentralized collection, a much-needed tool in COVID-19 testing.”

PerkinElmer’s comprehensive SARS-COV-2 offerings span RT-PCR, high throughput RNA extraction, automation, ELISA and other laboratory solutions. This DBS based test follows the recently CE-Marked ELISAs for detection of IgG antibodies from EUROIMMUN, a PerkinElmer company.

HematologyIn Haematology / Hematology, complete blood cell counts (or full blood counts) are obtained using automated blood count analyzers to enumerate blood cell types.  Hematology also encompasses haemostasis and coagulation, thrombophilia and hemophilia, plasma viscosity and ESR analysis, hemoglobinopathies, cell morphology and haematinic measurement.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.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.

Research into the biology, transmission, and treatment of coronaviruses has become a global priority, particularly since the emergence of SARS-CoV-2. Understanding the virus�s structure and behavior is essential for developing vaccines, diagnostics, and antiviral treatments. Explore our peer-reviewed product directory to discover the latest research tools, diagnostic tests, vaccines, and treatments for coronavirus, compare products, read reviews, and receive pricing directly from manufacturers.
