Conceptual prototype of the SAMBA® II (Simple AMplification Based Assay), invented by Dr Helen Lee, developed and made by Diagnostics for the Real World, 2012

The SAMBA® II was the result of ten years of development by Dr Helen Lee and her team. Dr Lee began the work for a point of care diagnostic device while working at the University of Cambridge’s Department of Haematology. Dr Lee won the Popular Prize European Inventor Award 2016 for her work with SAMBA® II.

Launched in 2014, the SAMBA® II is designed to be used at the point of care – bringing rapid results to people, particularly in the Global South. Originally designed for quick, easy, and reliable HIV testing, hepatitis C and COVID-19 tests are also available. Once samples are loaded into the SAMBA® II machine, the remainder of the process is fully automated. Uniquely shaped cartridges contain the reagents necessary for testing. Results are given in two ways – from a visual result using one or three lines – like some pregnancy tests and via a Bluetooth connected device. An integrated camera ensures consistent and accurate results.
