In this paper, we discuss the reasons why we urgently need a point-of-care (POC) CD4 test, elaborate the problems we have experienced with the current technology which hampers CD4-count coverage and highlight the ideal characteristics of a universal CD4 POC test. It is high-time that CD4 technology is simplified and adapted for wider use in low-income countries to change the current paradigm of restricted access once and for all.
