My Potassium Sensor

A project to develop a home test kit to empower patients to monitor blood potassium levels

 

About

The potassium test kit project

We are an interdisciplinary team of scientists and clinicians from the University of Cambridge and Addenbrooke’s Hospital, developing a device for home testing of blood potassium levels.

 

Specific groups of patients are at risk from abnormal potassium levels, which can in extreme cases be fatal. The idea for this device originated from patients themselves, via the Cambridge Patient-Led Research Hub. The device will allow patients can carers (or health care professionals) to monitor their blood potassium (K) levels, enabling them to participate in their own management, and ultimately increase both patient safety and quality of life.


The proposed kit will consist of a small handheld device, similar to a glucometer used by people with diabetes, coupled with single use, disposable sensors to measure potassium levels from a small drop of blood from a finger-prick.

 

Who can benefit from the kit?

  • Anyone with abnormally high K (hyperkalemia; above 5.5 mmol/L) levels

    • Patients on dialysis

    • Other kidney patients

    • People with familial hyperkalemic periodic paralysis (FHPP)

    • Those who take certain commonly-prescribed drugs:

      • medication for high blood pressure (ACE inhibitors, angiotensin receptor or mineralocorticoid receptor blockers)

      • some antibiotics, eg trimethoprim

      • calcineurin inhibitors (transplant recipients)

  • Anyone with abnormally low K (hypokalemia; below 3.3 mmol/L) levels

    • Patients with genetic kidney disorders such as Gitelman or Bartter Syndromes

    • Those who take certain commonly-prescribed drugs: 

      • diuretics

      • certain anticancer drugs

      • antivirals
