If it's a rapid it does not go by generations, which refer to ELISA. Just do the test after the window period and you will be fine.
thankou frank I didn't really know wether to ask my doc that. do rapid test have the same reliability as whole blod elisa
The manufater (Inverness medical) doesnt say what generation its, but after reading how the test works, it works like a 2nd generation test. an the rapid test are as good as any elisa for negative result.
