PointCheck is a portable, fast, and non-invasive white cell monitoring device.

Developed By Unknown
Content Partners


Product Description

The device works on the principle of imaging the blood flow and counting the number of white blood cells. PointCheck™ is a non-invasive device which allows immunosuppressed patients to get their blood check done. The device will potentially help health clinics in having more frequent and rapid testing done. Currently this is an investigational device and it is not for sale.

Distributors / Implementing Organizations

The company is supported by MIT Innovation Initiative, the MIT Deshpande Center for Technological Innovation, the MIT Sandbox Innovation Fund, the Martin Trust Center for Entrepreneurship, the MIT Translational Fellows Program, and the MIT Venture Mentoring Service.

Manufacturing/Building Method

Leuko is working on developing prototypes and commercializing the technology with help from the MIT Innovation Initiative, the MIT Deshpande Center for Technological Innovation, the MIT Sandbox Innovation Fund, the Martin Trust Center for Entrepreneurship, the MIT Translational Fellows Program, and the MIT Venture Mentoring Service.

Design Specifications

The design of the device allows chemotherapy patients to prevent infections from needle-based tests. The device uses imaging technique which is non-invasive and thus quick check on white blood cell count can be done. The device is portable enough to be used in a clinic or home applications where the patient can have access to daily checks on their blood count. The device is enclosed in a plastic casing and is suitable for use in the home, clinic, or healthcare centers. PointCheck™ is able to determine if white cell levels are dangerously low by imaging the blood flowing through the capillaries in the finger. PointCheck does this without having to extract any blood

Technical Support

Not yet available as product is in prototype stage

Replacement Components

The replaceable component includes the battery


2-5 years

Manufacturer Specified Performance Parameters

Accurately measure white blood cell levels.

Vetted Performance Status

The team showed that the device could accurately determine whether white blood cell levels were too low, in a study of 11 patients undergoing chemotherapy.


No known safety hazards are related to this product.

Complementary Technical Systems

A reliable power source is required for the device to function and read the blood flow.
