Nerve Disorders in Focus | Guillain-Barré Syndrome Diagnostics Market Gains Ground with Improved Clinical Awareness

The Guillain-Barré Syndrome diagnostics market has been steadily growing in recent years and is expected to continue this growth trend, with some acceleration over the forecast period, as advancements in neurodiagnostics, clinical awareness and early intervention efforts help improve detection and care. The Guillain-Barré Syndrome market has attracted significant attention from healthcare systems, clinicians and diagnostics technology firms in recent years as the prevalence of neurological disorders and post-infectious autoimmune conditions has increased globally.

Overview of Guillain-Barré Syndrome

Guillain-Barré Syndrome (GBS) is a rapid-onset autoimmune disorder in which the body’s immune system attacks the peripheral nervous system. It is characterized by muscle weakness, numbness and, in severe cases, paralysis. Guillain-Barré Syndrome can be triggered by viral or bacterial infections, and in some cases, vaccinations or surgery. Prompt diagnosis and treatment are crucial to prevent life-threatening complications and can lead to a full recovery if treated early with immunoglobulins or plasma exchange.

The clinical presentation of GBS can vary in intensity and location, with some common symptoms being muscle weakness and tingling sensations in the extremities, facial paralysis, difficulty breathing and abdominal pain. GBS is considered a medical emergency and requires immediate attention.

GBS Diagnostic Tools

The diagnostics process for Guillain-Barré Syndrome may include a combination of electromyography (EMG), nerve conduction studies (NCS), cerebrospinal fluid (CSF) analysis, and advanced neuroimaging techniques such as magnetic resonance imaging (MRI) to confirm the diagnosis and rule out other causes of neuropathy. Electromyography and nerve conduction studies help assess the electrical activity and function of the peripheral nerves.

CSF analysis, often referred to as a lumbar puncture or spinal tap, can help detect increased protein levels in the cerebrospinal fluid, which is a hallmark of GBS. Advanced neuroimaging, such as MRI, may also be used to visualize nerve inflammation and confirm the diagnosis.

Advancements in Portable EMG/NCS Devices, Automated CSF Testing, and AI-Assisted Neuroimaging Are Expediting GBS Diagnostics

In recent years, the Guillain-Barré Syndrome (GBS) diagnostics market has seen notable advancements in technology and increased adoption across geographies as newer and more advanced tools have made their way into the hospitals and clinical labs. Portable EMG/NCS devices have become more compact and affordable, enabling their use in primary care settings. Automated CSF testing platforms have improved the speed and accuracy of CSF analysis, while AI-assisted imaging techniques have helped neurologists identify subtle signs of GBS more efficiently. These improvements have helped reduce the time to diagnosis in GBS cases, thereby improving patient outcomes.

Increasing Clinical Awareness & Training Initiatives

A key market driver on the clinician front is the global efforts being made to raise awareness about neurological conditions and prepare general practitioners and emergency medicine (EM) specialists to identify patients with symptoms suggestive of Guillain-Barré Syndrome (GBS). Through training and education initiatives, healthcare and medical societies are pushing doctors to familiarize themselves with published guidelines and ensure early referrals for patients who may be experiencing GBS symptoms such as limb weakness, facial paralysis or lack of muscle tone and reflexes.

Misdiagnosis and delayed diagnosis of GBS remain high-risk factors, leading to increased patient morbidity and mortality and has been at the forefront of healthcare initiatives in major geographies. Additionally, GBS screening protocols are being adopted by infectious disease follow-up programs for diseases such as dengue, Zika and COVID-19 in high-risk countries.

Geographical Segmentation

The Global Guillain-Barré Syndrome Diagnostics market is segmented into seven regions, including North America, Latin America, Western Europe, Eastern Europe, Asia-Pacific, Japan, and the Middle East & Africa (MEA). North America and Western Europe are the largest markets for GBS diagnostics globally. In these regions, there is a high prevalence of neurological disorders and post-infectious autoimmune conditions.

In North America, the GBS diagnostics market is driven by increased awareness of neurological conditions, leading to a higher demand for neurodiagnostic tests. There is a high adoption rate of portable EMG/NCS devices in primary care settings.

Europe and North America combined are responsible for more than 50% of the global GBS Diagnostics market, but the Asia-Pacific region is expected to witness the most rapid growth. Japan and South Korea will also see good growth, but there is less awareness about neurological disorders and the long-term impact of post-infectious diseases on the nervous system in the MEA region.

In the Asia-Pacific region, there has been a notable rise in the incidence of Guillain-Barré Syndrome in recent years. Guillain-Barré Syndrome can be caused by various factors, including viral and bacterial infections, vaccinations, and surgeries, with some of these causes more prevalent in Asia-Pacific geographies compared to the Western world.

The increasing prevalence of these risk factors is likely contributing to the rise in GBS cases in the Asia-Pacific region. The high incidence of neurological disorders and post-infectious autoimmune conditions in the region has also contributed to the rapid growth of the GBS diagnostics market. In addition to this, countries in this region are also investing heavily in healthcare infrastructure, leading to improved access to advanced diagnostic tools and technologies that can aid in the early detection of Guillain-Barré Syndrome. This, in turn, has contributed to the rapid growth of the GBS diagnostics market in this region.

Key Players in the Market

The market is quite fragmented with a fair number of small firms focused on developing point-of-care tools for neuro testing and testing equipment providers getting into the space with new offerings. These companies are introducing novel products that are portable, easy to operate and aimed at deployment in community clinics and rural hospitals. Some of the leading companies in the GBS Diagnostics Market include Hansa Biopharma, Thermo Fisher Scientific Inc., Siemens Healthineers AG, Abbott Laboratories, GE Healthcare, Medtronic, Neurotronics GmbH, and Neural Insight Pte Ltd.

Recent Developments

In December 2024, Hansa Biopharma announced the start of enrollment for a Phase II clinical trial to evaluate the potential of imlifidase as a treatment for Guillain-Barré Syndrome (GBS), the condition is also known as acute inflammatory demyelinating polyradiculoneuropathy (AIDP). The trial will assess the safety, tolerability, and efficacy of a combination therapy of imlifidase and standard Intravenous Immunoglobulin (IVIG) treatment in GBS patients.

In October 2023, the European Academy of Neurology and the Peripheral Nerve Society released new guidelines for the diagnosis and treatment of Guillain-Barré syndrome (GBS), using the GRADE methodology. Key recommendations include: early intravenous immunoglobulin (IVIg) or plasma exchange for patients diagnosed within two to four weeks, and testing for anti-GQ1b antibodies for patients with Miller Fisher syndrome, a rare GBS variant, and assessing prognosis with the modified Erasmus GBS outcome score (mEGOS).

In October 2023, a study published in Neurology showed that recent COVID-19 infection increased the risk of developing Guillain-Barré syndrome (GBS) six-fold over the next six weeks. The researchers analyzed GBS cases from 2020 to 2022 and found that 12% of GBS patients had a recent infection compared to just 2% of non-GBS patients. Additionally, the study showed that those who received the Pfizer-BioNTech mRNA vaccine had a reduced risk of GBS, highlighting the vaccine’s protective effects.

Conclusion

As the burden of neurological disorders continues to rise across geographies and demographics, the focus on Guillain-Barré Syndrome diagnostics is only increasing. With more clinical awareness, better diagnostics infrastructure and technologies that are on the cusp of disruptive innovation in GBS, the market is only set to grow in the coming years. Accurate and timely diagnosis of Guillain-Barré Syndrome is the first step in initiating effective treatment for the rare but debilitating condition, and as healthcare systems adapt and learn to deal with its growing incidence, Guillain-Barré Syndrome care is set to become more responsive, efficient and patient-centric than ever before.
