Welcome to the forum. Thanks for a sucinct question; my reply is similar.
The borderline result on the first test (chemoluminscence May 29) was indeterminate, i.e. uncertain positive versus negative. Most such results turn out to be negative for HIV, as it did in you. Your second test (actually two tests, CMIA and Western blot) confirmed that the first test was false, as expected: for sure you do not have HIV.
All this assumes the tests were done at least 6 weeks after your last possible exposure to HIV. If you might have been at risk more recently than that, you should consider having another test when 6 weeks have past.
For any future testing, avoid the chemiluminscence-VITROS test, which might give the same false positive results.
I hope this has been helpful. Best wishes-- HHH, MD
1) Have any antibody test, except for VITROS. Follow your doctor's or clinic's advice.
2,4) It is too late for post-exposure prophylaxis (PEP) with HIV drugs, unless you have been exposed within the last 3 days. And even then, it may not be recommended, depending on what kind of exposure you had. If it is still within 3 days, see an HIV expert and then follow his or her advice about which drug to take, side effects, etc.
3) The numerical value (0.14 or any other) doesn't mean anything. That test result is totally negative.
