The global diagnostic testing market size was valued at USD 213.27 billion in 2023 and is expected to hit around USD 423.85 billion by 2033, growing at a compound annual growth rate (CAGR) of 7.10% from 2024 to 2033.
Diagnostic testing refers to the investigation of biological materials or information for the purposes of identifying, confirming, or monitoring disease, conditions, or health status. These various tests may include blood tests, imaging studies, molecular assays, genetic screening, among others. Diagnostic testing allows health care providers to make appropriate decisions on diagnosis, treatment, and management of diseases by the early detection of conditions, the ability to monitor the progression of disease, and the assessment of the effectiveness of treatments. Diagnostic tests are of prime importance for effective health care delivery that would improve patient outcomes.
The diagnostic testing market is important in increasing efficiency and accuracy in healthcare. It represents a wide range of services and products that attempt to achieve this goal of improved patient outcomes through early diagnosis and correct identification of patients. This is driven by an increasing demand for rapid and accurate diagnostic tests, new molecular diagnostics, and diagnostics that incorporate AI and ML into their platforms. A surge in the adoption of POCTs and at-home diagnostic solutions continues to enhance access to essential healthcare services, thus offering early diagnosis and treatment options for a range of diseases.
According to Aspire Circle, the whole industry of medical diagnostics accounts for only 4-5% of all healthcare expenditure but influences the remaining 95% of the cost. Also, almost 70% of the medical decisions related to early diagnosis of a disease, prognosis of patients, and selection of treatment are based on laboratory diagnostic results.
The National Library of Medicine, citing a study on cervical cancer screening in sub-Saharan Africa, observes that it ranges between 2 and 20.2 percent in urban areas, while it stands at between 0.4 and 14 percent in rural areas. It is reported that barriers to screening, as identified in countries like Malawi, include cultural influences, religion, lack of knowledge about cervical cancer, low levels of awareness about prevention procedures, confusion between screening and diagnostic tests, fear of stigma, and embarrassment about the screening procedure.
