Thanks for your query, albeit short and specific.
Noted the history of white spot on throat in spite of negative strep test 4 days ago.
Strep tests shows positive only when the throat infection is caused by the small group of bacteria called as streptococcus bacteria.
There are a number of other types of bacteria that too can cause sore throat and infection.
Hence there can be bacteria other than streptococcus type that can cause infection and cause white spot on throat.
I hope this answers your query.
