CD4 and tuberculosis: In 2010, pregnant women and patients co-infected with tuberculosis (TB) presenting with CD4 ≤ 350 cells/μL were eligible to initiate ARV, while the CD4 ≤ 200 μL remained in place for others and the diagnosis of VL failure now required two consecutive VLs of ≥1000 copies/mL three months apart [14].
