Macro drivers—rising birth rates in Asia-Pacific, two-fold expansion of the U.S. Recommended Uniform Screening Panel (RUSP), and reimbursement schemes across EU-5—anchor the market forecast toward US$ 2.2 billion by 2033. Technology shifts to tandem mass spectrometry and next-generation sequencing shorten lab turnaround times, while heightened competitive intensity (PerkinElmer, Waters, Thermo Fisher, and regional PPP labs) compresses reagent margins by ~150 bps per annum. North America retains the largest revenue share (42%), but South Asia & Pacific is the fastest-growing region (>9% CAGR) as India, Indonesia, and Vietnam launch national DBS programs. Supply-chain resilience, particularly for 3-mm filter cards and enzyme reagents, remains a C-suite priority amid post-pandemic logistics constraints.
