Relating to my other questions on hiv i have a closure finally.?

i went to local ual health clinic run by a hospital and did the rapid hiv test. they took a finger prick sample of my blood and tested it where you get the results in a hr when testing it they had a control line to show the test has worked and then if no other lines showed that means it was a negative if another line showed it meant it was a positive so they would have to take a sample of my blood and send it to the lab to be retested to make sure. as the health advisor said that the rapid hiv test is so sensitive it can pick up any antibody and think that it may be hiv. so when a positive happens they send to confirm the result. my test came negative she called me in after 30mins of doing the test and still after 40mins the results did not change. so am i definately a negative since the last time i had was in jan this year with my bf and if i had b4 him like from 5yrs ago with my ex it wud have shown. taking a finger prick blood sample is it the same as a normal blood sample?
