Nucleic acid amplification testing for HIV was instituted in donor testing protocols to:

a. Identify donors with late-stage HIV who lack antibodies

b. Confirm the presence of anti-HIV in asymptomatic HIV-infected donors

c. Reduce the window period by detecting the virus earlier than other available tests

d. Detect antibodies to specific HIV viral proteins, including anti-p24, anti-gp41, and anti-gp120
