Key Market Challenges

High Cost of Testing & Limited Accessibility

Expensive diagnostic procedures remain a significant barrier, particularly in developing regions where healthcare infrastructure is less advanced. Many vitamin D tests, especially 25-hydroxy vitamin D assays, require specialized equipment and trained professionals, increasing operational costs for laboratories and healthcare providers.

The lack of reimbursement policies for routine vitamin D testing in certain countries discourages patients from undergoing regular screenings, limiting market penetration. In rural and underserved areas, access to advanced diagnostic facilities is restricted, preventing widespread adoption of vitamin D testing.

Variability in Testing Standards & Accuracy Concerns

The lack of global standardization in vitamin D testing methods leads to inconsistent results, affecting clinical decision-making. Different laboratories use varying assay techniques, such as ELISA, HPLC, and LC-MS, which can produce discrepancies in vitamin D level measurements.

The absence of universally accepted reference ranges for vitamin D levels creates confusion among healthcare providers, impacting treatment protocols. Emerging point-of-care testing (POCT) devices and home-based kits face challenges in achieving high accuracy, limiting their adoption in clinical settings.
