Hi there,
I had an unprotected sex on the 11th of April 2021. I had an HIV test Alere Combo rapid on the 5th of July 2021 (85 days later) and the result was negative.
I am aware that combo test (4th generation test) result is conclusive after 4 weeks. However, I only know laboratory 4th generation test and this is the first time I know about rapid (Alere) 4th generation test.
May I ask:
1) Are there any differences between rapid Combo test (Alere) and conventional Combo laboratory test? Is the finger prick blood resulting in longer window period (longer than 4 weeks), and if so, for how long?
2) Is my negative test result on Combo Alere rapid conclusive at 85 days?
Many thanks for your help.
