SAMBA has been operational at Namitambo Health Centre since the end of Summer 2013 (note: 55-56 is PIMA). 140 tests per month since then and patients get results same day. The machine just indicates if the patient has a viral load above or below 1,000 copies (per ml). Importantly, there is no need for cold storage of reagents. It is electrically powered with a back upbattery to secure power during power-cuts.
