Immune system impact of duration of

Does immune system strength prior to exposure have any affect on time to positive test result? I've always had a very strong immune system all of my life and don't get sick often. Had a neg test at 30 days. Just wondering if there is any known studies done on this.  Also - if one were to develop Lymphadenopathy would the lymph nodes be swollen in neck, armpits and groin, in just one of those areas or all? Thank you
