Serum Free Light Chain (sFLC) Assays Market Size, Share & Industry Analysis, By Technique (Latex Nephelometric/Turbiometric and ELISA), By Indication (Multiple Myeloma, Light Chain Amyloidosis, and Others), By End-user (Hospital Laboratories, Clinical & Pathology Laboratories, and Others), and Regional Forecast, 2024-2032

The global serum free light chain (sFLC) assays market size was valued at USD 227.2 million in 2023 and is projected to grow from USD 245.8 million in 2024 to USD 477.3 million by 2032, exhibiting a CAGR of 8.6% during the forecast period (2024-2032). Moreover, the U.S. serum free light chain assay market size is projected to grow significantly, reaching an estimated value of USD 218.7 million by 2032, driven by the rising adoption of serum free light chain screenings among the patient population in the region.

Serum free light chain (sFLC) assays are used to diagnose and monitor plasma cell disorders, such as multiple myeloma, primary amyloidosis, and related diseases, or to monitor the effectiveness of treatment. These tests measure the amount of lambda and kappa free light chains in the patient's blood and human serum.

There is a high prevalence of multiple myeloma globally. Moreover, the demand for highly sensitive serum free light chain (sFLC) assays has increased owing to the surge in the prevalence of multiple myeloma and the need for highly sensitive quantitative tests globally.

• According to data published by the Canadian Cancer Society in November 2023, about 3,900 of the Canadian population were diagnosed with multiple myeloma in 2023.

Thus, the industry players are emphasizing strategic market initiatives, such as acquisitions and partnerships, to expand the presence of their existing product portfolio globally. Moreover, the surge in extension of product approvals by regulatory agencies in existing quantitative analyzers will further drive the market during the forecast period.

• In January 2023, Thermo Fisher Scientific Inc., completed the acquisition of The Binding Site, from a shareholder group led by European private equity firm Nordic Capital, at USD 2.8 billion. The acquisition will allow the expansion of Binding Site's existing specialty diagnostics portfolio with the addition of pioneering innovation in diagnostics and monitoring for multiple myeloma.

The COVID-19 pandemic led to slower global market growth for serum free light chain (sFLC) assays in 2020 globally. Travel restrictions led to a substantial reduction in cancer testing volume across major regions during this period. Major players registered a decline in sales of their products in 2020, owing to lower demand across hospitals and clinical laboratories. However, the resurgence of patient visits toward clinical settings for diagnostic screening of chronic disorders, such as multiple myeloma, led to market growth in 2021.

Serum Free Light Chain (sFLC) Assays Market Trends

Shifting Focus Toward Free Light Chain Tests from Traditional Test Techniques

Laboratory methods for diagnosis, prognosis, and monitoring of monoclonal gammopathies in plasma cell cancers have evolved to include methods such as serum and urine protein electrophoresis, immunofixation electrophoresis, immunosubtraction, and mass spectrometry. However, these methods are insensitive in detecting and quantifying free light chains, oligo secretory, and non-secretory multiple myeloma proteins in patient samples for disease diagnosis of light chain amyloidosis and light chain deposition disease.

The serum free light chain assay can be used for real-time monitoring of disease progression or response to treatment in patients with monoclonal antibodies. Moreover, potential advantages associated with serum free light chain tests, such as high sensitivity, rapid quantification, and improved test results compared to traditional techniques, have led to its increased adoption in clinical settings.

• As per data stated by BLOOD RESEARCH in September 2022, serum free light chain techniques are more sensitive than protein and immunofixation electrophoresis techniques. They are useful in follow-up and disease monitoring of patients with low levels of monoclonal proteins.

Similarly, increasing penetration of serum free light chain tests across hospitals, clinical laboratories, and other techniques for improved test outcomes has driven the market's growth. Moreover, the rising adoption of immunoturbidometric methods using these assays for detecting light chain disorders has catered to the market's growth.

• According to data published by Nordic Capital in October 2022, the Binding Site revenues increased fivefold in 2022 and recognized sales with more than 40.0 million tests on a global scale.

Thus, factors such as the high potential advantages of serum free light chains compared to conventional methods and the high adoption of these assays in clinical settings are augmenting the market's growth.

Serum Free Light Chain (sFLC) Assays Market Growth Factors

Increasing Prevalence of Multiple Myeloma Among the Global Population to Boost Product Demand

The prevalence of multiple myeloma is increasing globally owing to a rise in causative risk factors, such as old age, family history, radiation exposure or the presence of other plasma cell disorders, including solitary plasmacytoma among the population.

• According to data revealed by NCBI in 2022, multiple myeloma represents about 1.8% of all new cancer cases and accounts for 10.0% of hematologic malignancies diagnosed in the U.S. each year.

The surge in prevalence has led to a rise in chronic disease awareness among the population and an increase in the number of patients undergoing blood chemistry tests and diagnostic laboratory tests across healthcare settings. Thus, the rising demand for diagnostic tests, such as serum protein electrophoresis (SPEP), immunofixation electrophoresis (IFE), and serum free light chain (sFLC) assays across clinical laboratories, is expected to boost the screening of multiple myeloma among patients, further propelling the market growth.

• As per Myeloma UK estimates, about 5,700 of the U.K. population are diagnosed with Myeloma annually in 2022.

Moreover, the high potential advantages of serum free light chain tests, such as high sensitivity and improved monitoring of disease progression, are further leading to their high adoption for detecting multiple myeloma among the population compared to blood chemistry and urine tests.

Thus, a surge in the prevalence of multiple myeloma among the geriatric population and the rise in multiple myeloma screening tests across healthcare settings is anticipated to drive market growth during the forecast period.

RESTRAINING FACTORS

Limitations Associated with Quantification of Serum Free Light Chain Assays to Restrict Market Growth 

In recent years, serum free light chain (sFLC) assays have been extensively adopted for detecting monoclonal antibodies to diagnose plasma cell cancers. However, technical limitations associated with using this quantification of free light chain assays, including detection error of antigen excess, underestimation or overestimation of test results, lot-to-lot variation and nonlinearity in output readings, are prevalent across clinical settings.

Moreover, other limitations, such as heterogeneous FLC and using different reagents and instruments for measuring FLC concentrations, may give diverging results that affect the assessment of patients with monoclonal gammopathies.

• Springer Nature Limited published research data in September 2022, where 75,422 participants were screened with serum FLC, serum protein electrophoresis and immunofixation tests. The serum free light chain (sFLC) assays concentration was greatly affected by kidney function among the patients, where 60% of participants had kappa and 21% had lambda FLC values more than the normal range of light chains. Thus, the FLC and FLC ratio reference intervals were inaccurately measured in chronic kidney disease patients.

Thus, the factors mentioned above, along with the limited global presence of the assays across developing countries and the lack of new product launches by industry players, are expected to hinder market growth.
