Point-of-care testing (POCT) devices are gaining traction in the Vitamin D Testing Market due to their speed, convenience, and affordability. These portable devices allow patients to get results within minutes without visiting large laboratories. As per Vitamin D Testing Market, POCT is particularly beneficial in rural and underserved areas with limited healthcare infrastructure.

The integration of smartphone applications and connected devices further enhances patient engagement by providing instant access to results and recommendations. The adoption of POCT is expected to expand significantly, making vitamin D testing more accessible to global populations.
