TL;DR: The ultrasensitive p24 antigen assay has been proposed as an accurate substitute for PCR testing of HIV infection in infancy in low resource settings; however, its ability to detect different HIV viral subtypes remains to be determined.
Abstract: The expense of PCR testing limits diagnosis of HIV infection in infancy in low resource settings. The ultrasensitive p24 antigen assay has been proposed as an accurate substitute; however, its ability to detect different HIV viral subtypes remains to be determined. A sensitivity of 98.1% and specificity of 98.7% was obtained testing 203 samples from 24 HIV-infected and 66 uninfected infants born to HIV subtype C-infected women.
