Problem being addressed[edit | edit source]
For people living with HIV, the presence of the virus can be detected through a CD4 cells, which are cells that fight infection. In general as HIV progresses, CD4 cells go down which is indicative of a weakening immune system. For HIV-infected patients, a CD4 count should be administered before anti-retroviral therapies begin. However, modern technology for CD4 counting is not easily accessible throughout the developing world. Current technology, such as the flow-cytometry CD4 counter, range from US$30,000–$150,000 which is beyond the affordability for health systems with financial constraints.
Detailed description of the solution[edit | edit source]
The PointCare NOW machine is a portable blood-testing device that counts CD4 positive T cells and may help detect the presence of opportunistic infections in HIV patients. It is compact and designed to cope with the demands of remote locations. This device gives diagnostic results within minutes at the point-of-care, enabling immediate counseling and care by the physician. The product has a lifetime of 180,000 days,[verification needed] uses little power, and it can store thousands of patient records with a USB memory stick.

When and where it was implemented[edit | edit source]
This device is currently being used by the medical personnel of the Bwindi Community Hospital in Uganda. The equipment is taken to remote areas to provide health care to thousands of people. Before the equipment, patients usually walked long distances to the hospital.
