[Question #5555] Result interpretation

21 months ago
Hello
Sorry to return again.  About a month and a half ago I had a root canal in my tooth.  About three weeks later I had fever 101 degrees and accompanied with loose motions for a day. Fever and loose motions subsided after a day and then I developed cold and cough with white thick mucus that is common in cold  it lasted for about a week or so. This let me thinking as to ARS symptoms after my dental procedure. So I waited for six weeks and got tested today with 4th generation CMIA. RESULT is NON REACTIVE index value 0.75 and cut off being 1 and above. 
1. I am worried as to the high index value nearing the cut off value. 
2. Should I be bothered about the high index value as long as it is negative. 
3.Do I need further testing .
I have no other exposure to be concerned about. Am I developing HIV phobia or is my fear justified?

Sorry for writing again. 
Also if I have any subsequent symptoms relating to fever, loose motions, sore throat, body pain etc. Should I be concerned  related to the encounter that I mentioned above? Or that I have nothing to be worried about. 
thank you sir

Welcome back to the Forum.  On this occasion, I happened to pick up your new question and will be answering you.  I did review your earlier interaction with Dr. Handsfield and agree with all that he said.  I also sense that you continue to worry about HIV related to no risk events.  I am not sure if you are wondering if your symptoms might be related to HIV risk somehow connected to your root canal or the other, prior episodes that you discussed with Dr. Handsfield.  Either way you need not be concerned.  With the exception of one intentional criminal event which occurred many years ago, HIV is not and has not been transmitted through dental procedures.  

Further, I should mention that the symptoms of the ARS are most commonly due to non-ARS causes.  Influenza, other community acquired viral illnesses, and other factors are far more likely to cause such symptoms than recently acquired HIV.  In studies where at risk persons (there is no indication that you are at risk) seen in Emergency Departments for ARS-like symptoms, less than 1% turned out to be the ARS.  In your situation, your risk is far lower than that.  Further, the test results you report prove that you have not recently acquired HIV and are definitive.  They should be believed.  In answer to your specific questions:

1. I am worried as to the high index value nearing the cut off value. 
No, the cut off value is of interest to the laboratorian but irrespective of the cut off value (which does vary from day to day and person to person) ANY result below the cut off provided a reliable negative results. You need not be concerned.

2. Should I be bothered about the high index value as long as it is negative. 
See above.  This index value is not a reason for concern.

3.Do I need further testing 
Absolutely not.

I hope this information is helpful.  EWH
