LONDON -- Imperial College London has received a £4.9 ($8.6) million grant from the Bill & Melinda Gates Foundation to develop a simple, affordable and rapid test to measure the health of the immune system in HIV/AIDS patients in developing countries.
The 'CD4 Initiative' will develop an easy to use device which can measure CD4+ T-lymphocytes in HIV+ patients. The CD4 cell count measures the number of these critical disease-fighting cells in the blood, a figure which health care workers need in order to make key clinical decisions in managing HIV disease, such as when to begin or to switch antiretroviral therapy.
