Brief Answer:
Not typhoid

Detailed Answer:
Hello

Thanks for the query

The test reports indicates that your blood does not contain typhoid. Typhoid test done early can be negative
However if you continue to have symptoms like loose motion and vomiting along with high grade fever then a repeat typhoid test can show positivity where 1:80 can become 1:360, then is it known as 'reactive or a positive widal test'

I hope I was of help, please get back to me if you have any further doubts
