Helen Lee – Insights on Inventions, Patents, and Patent Applications

Helen Lee has dedicated her whole life to research in diagnostics. She has bestowed this world with wonderful inventions that help detect infectious diseases like Hepatitis-B, Covid-19, HIV, etc. to save millions of lives around the world.

She is the inventor of an instant blood diagnostic kit known as SAMBA (Simple Amplification Based Assay) that makes on-the-spot detection of infectious diseases like HIV, Hepatitis-B, and chlamydia possible.

The test kit is designed specifically for the African continent where 69% of the world’s HIV-positive peoples live. It can be stored up to 37°C for nine months and requires no trained personnel. SAMBA can detect the presence of the virus and viral load within minutes visible to the naked eye–no relying on costly microscopes. SAMBA runs on electricity but can function on batteries for eight hours.

Also, as it detects viruses directly from blood and not antibodies, it is instrumental in detecting HIV in infants that have not yet developed antibodies. 91% of the world’s HIV-positive children live in Africa make her invention more instrumental in saving the life of infants.

Lee’s rapid diagnostic kit has an enormous impact on infectious disease management. By 2016, SAMBA diagnostic kit screened 40 000 people for HIV in Malawi and Uganda. During the Covid-19 Pandemics, the diagnostic kit SAMBA has been repurposed as SAMBA II for detecting the COVID-19 virus
