I have never shown any symptoms and have not been sexually active for about a year, and I've only ever have has sex with condoms in my life. Due to my low risk factors and lack of symptoms, do I need to be tested again?

I actually don't think that you need to be tested again since it has been a year since you've had sex.  While the IgG test does miss 30% of HSV 1 and 8% of HSV 2, since you've used condoms with all encounters in your lifetime, I think your risk is really low.  You are not in the process of serconverting - that is going from negatie to positive - since your time of last sexual encounter was so long ago.  If you want more certainty about your herpes status, the herpes western blot is the gold standard against which all other tests are compared.

I think it is highly unlikely that you have herpes, I would not say I am sure that you don't since the test does miss 8% of HSV 2 infections.
