it's a yes/no test, no shades of grey the antigens are either present or not
"faint" pos is a meaningless term Barb+Smoky the House Puma+El Bandito Malito "My cat the clown: paying no mind to whom he should impress.

I gather that means that Bicford has been exposed, so has antigens, but doesn't have the virus in his blood? I'm confused. Can someone help me with interpreting what that means?
