Very good.
Now I have a tricky question on blood screening. It seems to me from the testimony we've heard that when it comes to HIV, I think 50% of the people who are getting HIV now are actually women who are with men who have sex with men. Is there a screening test? We talk about how we want to make sure that gay men can donate blood. The concern would be about the 130 times the risk of AIDS or HIV. I think that risk probably also exists in some percentage of the heterosexual population. Is there any screening test for that?
