MicroBioSensor currently has three products in development based on its underlying MicroBioSensorâ„¢ technology.



Our lead product, QuickCheck, is an early warning system for life-threatening peritonitis. The QuickCheck device enables medical staff to be alerted if high leukocyte or microbial cell levels are indicated by a colour change in any of three windows. These results are available immediately at the end of an overnight dialysis session.

QuickCheck also provides sensitivity data for vancomycin, the front line antibiotic most most commonly prescribed for infective peritonitis. It is therefore able to flag an emerging infection at an early stage and confirm infective peritonitis without further delay: something no other product on the market can do. It also provides guidance on the correct choice of antibiotic to treat the infection.

The QuickCheck device is currently undergoing clinical assessment in a multi-centre clinical study. A self-certified CE Mark filing is planned in 2021.

A version of QuickCheck for use at home will enter clinical assessment for self-use by patients in 2022, ahead of CE Marking (via our Notified Body) for approval in 2023.


STAR System

The STAR system has been developed to test urine samples from UTI patients for antibiotic resistance against five commonly used antibiotics.

A key component is the development of an optical reader for assessing the output of the device, which enables a readout within five hours, and appreciably reduces the size of the companion instrument. The STAR cassette has been designed to provide an automatic diluting function, to enable the device to be used by untrained workers in a care home pharmacy or GP clinic setting.

The cassette and optical reader designs are being finalised and tested by our design and prototyping partners Smallfry (Coventry), and Datalink Electronics (Loughborough).

A clinical assessment is underway to finalise the sample processing protocol ahead of a CE Mark clinical study scheduled for 2021.


PERIFAST: Peritoneal Fluid Antimicrobial Sensitivity Test

PERIFAST is a powerful in-clinic product, providing rapid antimicrobial sensitivity testing for patients arriving at hospital with peritonitis (either PD peritonitis or SBP). PERIFAST will be positioned alongside QuickCheck as an essential test for all patients arriving at clinic with suspected peritonitis.

The system is based around the STAR optical reader and cassette which will be adapted for use with a higher number of antibiotics. This R&D programme is ongoing, and the product will enter full clinical assessment in 2022.
