Blood self-sampling devices: innovation, interpretation and implementation in total lab automation

Area of Science:

• Clinical diagnostics
• Laboratory medicine
• Healthcare logistics

Background:

• Vacuum tubes revolutionized blood collection in 1949, enhancing sample quality and patient comfort.
• Laboratory diagnostics have automated significantly, reducing required test volumes over 1,000-fold.
• Venous blood collection faces logistical issues like centralized scheduling and excessive biological waste.

Purpose of the Study:

• To explore the evolution of blood collection methods and their impact on laboratory diagnostics.
• To identify challenges associated with traditional venous blood collection.
• To evaluate the potential of capillary blood self-sampling for decentralized healthcare and patient empowerment.

Main Methods:

• Review of historical advancements in blood collection technology.
• Analysis of logistical challenges in current diagnostic workflows.
• Examination of emerging self-sampling devices and their implications for point-of-care testing.

Main Results:

• The COVID-19 pandemic highlighted the need for decentralized healthcare and patient-centric solutions.
• Capillary blood self-sampling shows promise for point-of-care testing and patients with difficult venous access.
• A 15% reduction in lab tests at Leiden University Medical Center was linked to patient preference for local collection.

Conclusions:

• Self-sampling devices are crucial for patient empowerment and streamlined diagnostics, despite challenges like cost and transportation.
• Robust, user-friendly, affordable, and sustainable self-sampling devices are essential for widespread adoption.
• Self-sampling represents an inevitable shift towards patient-centered, proactive healthcare, enhancing convenience and cost-effectiveness.
