Regional Analysis
North America led the global therapeutic drug monitoring (TDM) market in 2023, accounting for the highest revenue share of 41.4%. This dominance is attributed to the high prevalence of chronic and autoimmune diseases that require precise medication management. A 2022 study reported that over 15 million individuals, or 4.6% of the U.S. population, had been diagnosed with at least one autoimmune disorder, underscoring the demand for individualized drug dosing.
Additionally, organ transplant procedures, which require consistent TDM to manage immunosuppressant therapy, are increasing. In Canada, 3,369 solid organ transplants were recorded in 2023, up from 2,886 in 2022, according to the Canadian Institute for Health Information (CIHI). The presence of major diagnostics companies, such as Abbott Laboratories with revenues rising to US$41.95 billion in 2024 further supports market growth.
The Asia Pacific region is projected to register the fastest compound annual growth rate (CAGR) during the forecast period, driven by demographic shifts and healthcare expansion. China’s diabetes population reached 233.03 million in 2023, and Japan had 893,673 epilepsy cases in 2022, both requiring consistent drug monitoring. Moreover, India’s total health expenditure exceeded US$904,461 crore in FY 2022, reflecting a commitment to improving healthcare access, which will further support the adoption of TDM in this region.
Emerging Trends
- AI-Driven Precision Dosing: Artificial intelligence (AI) and machine learning (ML) are increasingly integrated into TDM workflows to inform model-informed precision dosing (MIPD). These computational tools analyze multidimensional data such as electronic health records and pharmacokinetic profiles to predict individual drug exposure and recommend optimized dosing regimens, enhancing both safety and efficacy in clinical decision support.
- Pharmacometabolomics and Pharmacogenetics: There is growing use of pharmacometabolomic analyses profiling individual metabolic fingerprints—to tailor drug dosing based on patient-specific metabolism. Coupled with pharmacogenetic testing of gene variants that affect drug metabolism, this trend supports truly personalized therapy by identifying patients at risk of under- or over-exposure before treatment begins.
- Mass Spectrometry Platforms: Liquid chromatography-tandem mass spectrometry (LC-MS/MS) is supplanting traditional immunoassays in many clinical labs. LC-MS/MS offers higher sensitivity, specificity, and throughput, allowing rapid quantification of drugs even those lacking natural chromophores while automated sample preparation and online extraction streamline workflows.
Use Cases
- Baricitinib in Pediatric Patients: A validated LC-MS/MS method measures baricitinib levels in plasma (50 µL sample) across 1.024–100 ng/mL. In one study, mean concentrations were 11.25 ± 10.86 ng/mL, enabling clinicians to adjust dosing in juvenile rheumatoid arthritis to achieve optimal exposure and minimize toxicity.
- Multiplex Monitoring of Mycophenolic Acid and Triazoles: A clinical laboratory implemented a multiplex LC-MS/MS assay to quantify mycophenolic acid (MPA) and triazole antifungal levels in serum. The assay demonstrated a wide dynamic range and low detection limits, supporting dose adjustments in transplant recipients and patients with invasive fungal infections to maintain therapeutic windows.
- Rapid Colistin TDM: An LC-MS/MS assay for colistin in human plasma uses a 1 mL sample and completes analysis within four minutes. This method’s speed and precision support monitoring in critically ill patients, ensuring colistin concentrations remain within the narrow therapeutic index to balance efficacy against nephrotoxicity.
Conclusion
The global Therapeutic Drug Monitoring (TDM) market is evolving as a critical component of precision medicine, offering targeted drug dosing to improve treatment outcomes and patient safety. While North America leads the market due to advanced healthcare infrastructure, Asia Pacific is projected to grow rapidly, driven by rising chronic disease prevalence and healthcare investment.
