Rising requirement for cancer diagnostics
According to the National Institutes of Health's projection, there will be approximately 1,958,310 cancer cases in the United States in 2023. This number of rising cases of cancer brings demand for early diagnosis of cancer across the globe. Molecular diagnostics plays a crucial role in the early detection of cancer. Molecular diagnostics identify cancer-related biomarkers at an early stage, healthcare providers can diagnose cancer before symptoms arise, leading to earlier treatment initiation. Cancer continues to be a leading cause of morbidity and mortality across the globe, as the cancer cases increase, the demand for accurate and precise diagnostic method also grows. This element is observed to pose a driver for the market.
Development of precision medicine
Precision medicine focuses on tailoring medical treatments and interventions to individual patients based on their unique genetic makeup, lifestyle, and environmental factors. Molecular diagnostics play a crucial role in this approach by enabling the identification of specific biomarkers, genetic mutations, and gene expression patterns that can guide treatment decisions for each patient. Molecular diagnostics have become an essential component of the drug development process. Companion diagnostics are tests used to identify patients who are most likely to respond positively to a particular treatment. By identifying suitable candidates for specific therapies, companion diagnostics help pharmaceutical companies improve the success rates of clinical trials and streamline the drug development process. Thereby, drives the growth of the market.
Presence of alternative diagnostic methods
Alternative diagnostic methods, such as traditional laboratory tests or imaging techniques, may already be established and widely accepted in the medical community. When molecular diagnostics compete with these existing methods, it can be challenging to gain market share and acceptance, especially if the alternatives are perceived as more cost-effective or easier to implement. Molecular diagnostics often involve sophisticated technologies and specialized equipment, making them more expensive than some conventional diagnostic methods. This cost factor can hinder their adoption, especially in resource-limited settings where healthcare facilities may not have the financial means to invest in expensive molecular diagnostic infrastructure. Thus, the presence of alternative testing methods in the market creates a restraint for the market.
Stringent regulatory policies
Stringent regulatory requirements act as barriers to entry for new entrants in the molecular diagnostics market. As a consequence, established companies with already approved products may have a competitive advantage, making it difficult for newcomers to gain a foothold. Regulatory agencies often work closely with healthcare payers to determine the coverage and reimbursement of molecular diagnostic tests. Uncertain or restrictive reimbursement policies can create financial uncertainties for companies, affecting their willingness to invest in research and development, market expansion, or product improvement. Such policies or guidelines are observed to hamper the market’s expansion.
Rising focus on less-invasive testing methods
Less invasive testing methods can enable earlier detection and continuous monitoring of diseases, leading to better treatment outcomes and overall patient management. Patients often prefer non-invasive or minimally invasive procedures as they are less painful, have shorter recovery times, and reduce the risk of complications. The aging population is more prone to chronic diseases that require frequent monitoring, making less invasive testing methods particularly beneficial for this demographic. Molecular diagnostics has enabled the development of blood tests that can detect specific genetic, or protein markers associated with various diseases. These tests can provide valuable information without the need for invasive procedures, making them more appealing to both patients and healthcare providers. Thus, the rising demand for less invasive testing methods creates significant opportunities for the molecular diagnostics market.
Data safety challenges
Molecular diagnostics heavily rely on the analysis and sharing of sensitive genomic information, data privacy and security becomes critical issues. The rise in cyberattack and data breaches to personal health information could deter patients and healthcare providers from embracing molecular diagnostics technologies. Concerns about how companies handle, or store genetic data might also deter users, patients or consumers from adopting such services. All these factors associated with data safety concerns create a significant challenge for the market.
The reagent segment had the largest market share until 2024. The revenue share of the reagents segment is expected to maintain its dominance in the coming years. The segment is expected to grow during the forecast period as it is widely adopted in many research and clinical settings. Standard reagents are effective in achieving efficient and extremely accurate results.
Due to the standardization of these results, improved efficiency and the cost-effective nature the segment is expected to support the growth of the market during the forecast period. In February 2022 Roche Diagnostics extended the COVID test portfolio to new cobas 5800 system in the countries that accept the CE mark approval.
On the basis of the test locations, the central laboratories had the largest market share in the recent years. In the future the central laboratory segment is expected to grow as there are high procedure volumes for COVID testing in these laboratories. An increasing number of initiatives that are taken by the government to provide different services like reimbursement for these diagnostics test is another factor that is helping in the growth of this market. There is a growing demand in the development of molecular diagnostic platforms which can also be used in POC settings. Many major market players are designing the molecular diagnostic platforms. The growing development of this platform will offer quick POC results which are expected to provide a boost to the market.
Till the year 2024, the infectious diseases segment accounted for the largest revenue share in the molecular diagnostics market. Due to the use of the tests for the diagnosis of COVID-19 the infectious diseases segment dominated the market. In the coming years the oncology segment is expected to drive the market.
The oncology segment is expected to have a high CAGR during the forecast period. About 19.3 million cancer cases were diagnosed across the globe in the year 2020 in order to provide better access and the improvement in the oncology molecular diagnostics the British in vitro diagnostics association along with NHS England developed a commissioning framework for molecular diagnostics in oncology.
The use of PCR technology to detect various infectious diseases or genetic diseases is expected to drive market growth. The polymerase chain reaction segment had the largest revenue till the year 223 due to its use in the detection of COVID-19 and other infectious diseases in the recent years.
