For Patients & Caregivers
A simple finger test, no needles.
PointCheck™ is being developed to help people undergoing cancer therapy — and their care teams — keep an eye on white blood cell levels from home, without needing a blood draw.
Why white blood cells matter
White blood cells help your body fight infection. Some anti-cancer therapies can temporarily lower your white blood cell count (a condition called neutropenia) in between treatment cycles. During that time, even a small infection can become serious quickly.
Today, the only way to check your white blood cell count is a lab blood draw, usually scheduled around treatment visits. PointCheck™ is being studied as a way to perform this check regularly and at home, with light shined gently on the fingertip — no needles, no lab samples required.
No needles. No blood sample.
PointCheck™ uses light to look at the tiny blood vessels (called capillaries) just under the top of your fingernail. Nothing is taken from your body.
Designed for the home.
The device is portable and the test is short. The goal is to allow monitoring in between treatment cycles without extra trips to the clinic.
Your care team stays in charge.
PointCheck™ is a screening tool. If something looks off, your doctor decides whether you need a follow-up blood test or treatment.
Still being studied.
PointCheck™ is investigational and not for sale. It is being evaluated in clinical studies at hospitals in the United States and Europe.
Common questions
- Does it hurt?
- No. The device shines light on your fingertip; nothing breaks the skin and no sample is taken.
- Can I get one?
- Not yet, PointCheck™ is not approved for clinical use. Once it is, it will be available through your care team, much like other prescription medical devices.
- Will it replace my blood tests?
- It is being studied as a way to screen for low white blood cell counts between scheduled lab tests, not as a replacement for the complete blood counts your care team orders.
- How can I take part in a study?
- Studies are run through partner hospitals. Ask your oncology team if a Leuko study is available at your site, or get in touch and we can share active study locations.
