"Can you develop a novel blood self-sampling device?"

Ensuring standardized, safe, and user-friendly sample collection for home-based testing, compatible with at-home tests and central laboratory workflows?

The Challenge

Traditional capillary macro-sampling methods for blood collection (volumes ranging 500µl-1000µl), including the commonly used free-fall method, present significant challenges. These methods are often unhygienic, impractical, and prone to errors. The need for an improved blood collection device that addresses these drawbacks has prompted the search for a solution.

The Solution

The blood self-sampling device developed by Voxdale and ITM holds promising potential for a range of applications in research and clinical practice. It will reduce the burden on healthcare systems by lowering the number of visits to healthcare facilities in case frequent blood sampling is needed. The device can be used for several purposes such as screening for infectious diseases, monitoring chronic diseases, and seroprevalence studies, …. Moreover, the self-sampling device may be used in different cultural and logistical settings. Future studies will explore the device's efficacy in these scenarios.
In recognition of its innovation, the blood self-sampling device has been filed for a patent.

Iterative Prototype Refinement

Through rigorous testing and valuable user feedback, prototypes are refined to surpass industry standards for medical device development. Each iteration brings us closer to an optimized solution that ensures the highest quality and performance.

The blood self-sampling device guarantees standardized and reliable sample collection. With a focus on user-friendliness and ease of use, a device is designed to simplify the blood sampling process, ensuring accuracy and minimizing discomfort for the users.

Currently, pilot testing of the prototypes is ongoing in a Belgian clinical setting with a sample size of 50 participants. Preliminary results from a study involving 10 participants demonstrated the device's high user-friendliness, and robust user confidence to use the device correctly.


Moreover, participants reported minimal discomfort while using the device. Six participants successfully collected 750 µL or more of blood, while two collected between 250-500 µL. To address the challenges faced by two participants who were unable to collect any volume of blood, additional lancets will be provided to allow for additional attempts.

Moving forward, our focus lies on creating a final prototype that is safe, reliable, cheap and user-friendly which will be able to revolutionize the world of blood self-sampling and which can be used in diverse healthcare settings.

This project is funded by VLAIO.


Voxdale collaborated with Mahindra Racing to optimize and design the gearbox casing and construct the body for the racing simulator. These improvements enrich the overall racing experience and enable the team to better prepare for upcoming challenges.
