Immunochemistry Instruments and Reagents
Indian immunochemistry market plummeted in 2020
Immunochemistry analyzers are becoming more and more standard within the world clinical chemistry and immunoassay as these are proven to be an amazingly effective tool to diagnose cancer, hepatitis, illegal drugs, fertility issues, sodium levels, endocrine function, and the detection of blood clots. Use of immunoassays and other ligand-binding assays in clinical diagnosis has increased dramatically during the last several years.
There have been tremendous advances in IVD assays for coronavirus disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Two general methods are used in the diagnostic detection of COVID-19: the sequence-specific molecular nucleic acid test and the antigen-specific immunoassay. These techniques are the current gold standards for diagnosing acute infection and for monitoring immune response. There are now over 70 COVID-19 diagnostic tests that have been authorized for emergency use by the USFDA. The vast majority are molecular assays, while approximately one-fifth are antibody immunoassays.
Chemiluminescence immunoassays (CLIA) are quantitative serological antibody detection assays, which have high sensitivity and specificity. The enzyme-linked immunosorbent assay (ELISA) uses enzyme-substrate reactions to produce measurable signals proportional to the concentration of the target analyte. A defining feature of the ELISA is the immobilization of the target antigen upon a solid surface, usually in microplate wells. ELISA kits are sensitive, quantitative tests that can be used to measure a variety of analyte types within complex samples. Compared to the ELISA, lateral flow assays are generally qualitative, rather than quantitative. However, the relative simplicity of the procedure has led to the widespread development of various point-of-care and direct-to-consumer devices. Many tools are available that make it possible to run immunoassay experiments or even develop new, customized tests. At the heart of the assay are specific SARS-CoV-2 antibodies for targeting various antigens. Recombinant SARS-CoV-2 proteins can be used to develop controls or targets or to serve as antigens for immunoglobulins.
In the current COVID-19 pandemic, ELISA tests are playing a key role in testing, surveillance, and epidemiological studies. A typical ELISA protocol entails multistep manual operations that at some point become challenging from an operational and compliance perspective. The last two decades have seen tremendous innovation in ELISA technology. Automated ELISA processors are equipped with robotic probes and dedicated workstations, which drastically improve ELISA workflows, in terms of technology, features, accuracy, and cost-effectiveness.

The 22 percent decline, with the setback from COVID, hit the entire industry. There was some respite from the antibody tests conducted, but they only picked up pace later in the year. The serosurveys, conducted on a large number of people, by the government in several parts of India testing the presence of antibodies led to demand for the product.
In fact, the first quarter of 2021 has also been slow. It is only in May that the industry began to see some momentum. The government and the private sector started placing orders again, with a distinct bend toward automation. The incidence of COVID-19 has changed the mindset and now all laboratories have automation high on the agenda. However, with mandatory accreditation still not enforceable, the unorganized segment continues to thrive and with it the inefficiencies in the system.
Roche dominates this market, followed by Abbott, and Siemens, each at a 12-13 percent market share. Beckman Coulter and OCD are at around a 10 percent share, with bioMérieux estimated around 7 percent. Agappe, Transasia, and Mindray are also aggressive.

Enzyme-linked immune sorbent assay (ELISA) is a highly sensitive and selective analytical technique that is commonly used to detect the presence of a specific protein (antigen or antibody) in blood samples. Whether a lab works with direct, indirect, sandwich or competitive assays, ELISA protocols involve an exhausting number of dispensing, washing and incubating steps. However, this continues to remain the most widely used microplate assay in diagnostics and research.
The automation of ELISA systems, in the recent past, has further contributed to improving the turnaround time for critical tests.
In the wake of the increasing need to conduct different assays for infectious disease and hormone panels, management of multiple ELISA protocols manually, can be time-consuming. This is where automation of ELISA protocols plays a role in ensuring reliability and consistency in:
Time and temperature of incubation;
Reproducibility of washing process to avoid carry-over of sample and reagents; and
Simultaneous and sequential dispensing through robotic probes.
Besides this, most automated ELISA processors are open systems, allowing flexibility and greater degree of accommodation in expanding the test menu. Most importantly, automation helps in improving workflow efficiency by freeing the laboratory staff from repetitive steps. In fact, automation greatly improves the quality of data generated. It has been noted that on a standardized and validated automated system, replicates on a plate as well as across the plates, show lower co-efficient of variation (CV) when compared to a manual system.
Choosing the right ELISA automation for your lab
In order to gain maximum from automation, one should determine the scale and scope of automation, based on the lab requirement and choose an instrument accordingly. Thoughtful planning and careful implementation, based on test menu, workload and lab infrastructure, can determine the overall success of automating the ELISA process.
Automation can be implemented on the simplest assay format like an ELISA plate reader to a high capacity, modular 6-plate processors for multiple parameters. Transasia Bio-Medicals offers a complete range of fully automated 2½ and six plate ELISA microprocessors for a wide range of infectious diseases and hormone assays.
Stringent regulatory policies related to approval of immunoassay instruments and consumables are major restraints for the immunochemistry diagnostic devices and equipment market.
Immunochemistry devices and equipment manufacturers are required to obtain multiple and separate clearances from the Food and Drug Administration (FDA) for launching their products. The entire process of regulatory approval is time-consuming, with a minimum of about 18-30 months required for approval of class III devices and around 6-9 months required for approval of class II devices.
In the USA, the immunochemistry diagnostic devices and equipment market is regulated under the US Food and Drug Administration (FDA), and all diagnostic laboratory tests are regulated by the clinical laboratory improvement amendments of 1988 (CLIA), which is administered by the Centers for Medicare & Medicaid Services (CMS). A CLIA/FDA compliant laboratory is required to file a PMA/510(k) for market approval of any immunochemistry device. Hence, the regulatory scenario related to immunochemistry diagnostic devices and equipment will keep a check on the companies that manufacture these devices and equipment.
Under the robust rules and regulation laboratories notice it difficult to have good revenues. Therefore, it is vital to seek out ways to sustain in such a cost-crunched environment. Thanks to the price cutting in clinical lab fees, profit per check is decreasing that makes it necessary for the laboratories to focus on the volume instead of the worth. There is additionally significant pressure for quality, error-free results to ensure patient satisfaction. This forces labs to lean toward a lot of automated systems with effective workflow solutions.
Thermo Fisher Scientific, Siemens Healthcare, Roche Diagnostics, Abbott Diagnostics, Beckman Coulter, Danaher, Ortho Clinical Diagnostics, and others are among the major players in the global immunochemistry analyzers market. The companies are involved in several growth and expansion strategies to gain a competitive advantage. Industry participants also follow value chain integration with business operations in multiple stages of the value chain.

“Ongoing technological innovations have made immunoassay tests available and affordable to common individuals. This has expanded the testing volume and scope of tests with more and more immunoassays now becoming available on automated platforms. However there are certain challenges which need to be worked on. There is need to have more high throughput equipment. This saves space, manpower, and cost. More tests currently available only on ELISA need to be automated on one single platform. Issues like hook effect need to be worked out and systems to be created to nullify these errors. There is need to harmonize methods, biological references ranges amongst various manufacturers. Efforts also needed to have multianalyte calibrators as available for clinical chemistry. As technological innovations are moving at a rapid pace, I am hopeful that majority of these challenges will be resolved in coming years”.
