When and why

Serology refers to tests used to detect the presence of specific antibodies in the blood. These are checked to see if the individual has had a prior exposure to a specific infection.

Examples of specific serology tests are those for toxoplasmosis, cytomegalovirus (CMV), syphilis, and hepatitis. Serology samples are obtained from a venous blood draw.

How it will help

The presence of antibodies to an infection indicates that the individual has previously been infected. With some infections, people who have severe damage to their immune system are at risk of re-activation. Knowledge of this risk allows treatments to be started that can prevent or reduce this risk (prophylaxis).

Community Consensus Statement on Access to HIV Treatment and its Use for Prevention

Together, we can make it happen

We can end HIV soon if people have equal access to HIV drugs as treatment and as PrEP, and have free choice over whether to take them.

Launched today, the Community Consensus Statement is a basic set of principles aimed at making sure that happens.

The Community Consensus Statement is a joint initiative of AVAC, EATG, MSMGF, GNP+, HIV i-Base, the International HIV/AIDS Alliance, ITPC and NAM/aidsmap
