St Albans MP Anne Main had a HIV test as part of Halfway to World AIDS day.
On Tuesday, July 8 Mrs Main attended the event hosted by the Halve It Coalition and the All-Party Parliamentary Group on HIV and AIDS.
At the event 22 MPs, Peers and Councillors took a test administered by clinicians from the Chelsea and Westminster Hospital NHS Foundation Trust.
Mrs Main said: “It is important we do not relent on HIV as it continues to affect nearly 100,000 people up and down the country, the majority of whom have either been undiagnosed or were diagnosed late.
“What we do know is that, crucially, those who are diagnosed early are still able lead full and normal lives, and early detection substantially eases the burden on the NHS.”
