Hi . Your concerns and anxiety are understandable. I want to share with you this article from our editorial team on types of tests, with information on the testing window period: https://h-i-v.net/test-types. Also, I noticed that you mentioned the 4 gen test at 45 days, so I also want to share with you this site on window periods with a chart stating that "95% of people will be antibody positive by day 28 using a 4th generation test:" https://i-base.info/guides/testing/what-is-the-window-period#:~:text=Different%20types%20of%20tests%20have,to%20detect%2099%25%20of%20samples. Hope this information is helpful and please feel free to keep us posted on how you are doing. Best, Richard (Team Member).
