Table 1. Viral load assessment using ELISA, ELISA-EASE, and PCR in four HIV-infected patients’ plasma samples.

Serial bleeds were collected from individual patients over a course of 18 days during the development of HIV infection (first bleed as day 0). ELISA-EASE detects HIV p24 as early as PCR does.
