Suggest Treatment For Accidental Ingestion Of Water Contaminated With Chemical Agents

Hello. I have a question regarding a HIV self-test I did at home (I live in France, said test is a lateral flow test type). It s a test where you collect a drop of blood and it enters a tube with a strip into it. Reaction then make one or two stripes appear depending on the result. I accidentally dropped the test in my water glass (was almost full I reckon) in the bathroom. Since I had a call I forgot about it and emptied the glass around 15 mins later. Since then, I ve been worried the chemical reagents used in the tests (and not my blood, test was re-done and negative), could have contaminated my water. I may sound paranoid but I read that in some tests they use HIV antigens or such as reagents, and since the tube was in contact with my tap water glass, I ve been scared the dilution or something of that kind, woke up the antigens and infected my water. As I mentionned, I emptied the glass 15mins after this happened, but I did not disinfect it. Also, my bf and I used this glass to rinse our mouths after teethbrushing around 10 hours later. My bf told me he had rinsed the glass once more before using it. My question is : Has this test exposed me and my bf to any risk ? Should have I disinfected the glass due to possible residues or am I just worrying too much ? I d like to add I suffer from OCD and severe anxiety. I m scared for my health most of the time. Thanks for your attention, and please forgive any grammatical error, english is not my first language.
