My Urologists Assistant Called Me And Said I Tested Positive

My urologists assistant called me and said I tested positive for a yeast infection which I have never had, so I asked her if this is common and she said she did not know. On my labwork onlone it said "candida lusitaniae " I can not find info online other that that it is very rare and life threatening. I called a helpline nurse and she never hear of it before so I am very worried
