Chemotherapy is not antibiotic treatment. You have a conclusive test result. You are conclusively negative.
Even if they are IV antibiotics and not oral antibiotics? Sorry, just want to be sure because I heard IV antibiotics for chemotherapy can affect the HIV antibody test, even though these aren't for chemotherapy, but to treat a lung infection. How sure are you? Sorry I won't ask you again after this.
You are conclusively negative. Antibiotics will not skew your test results.
