However, the thing is that they gave me 3 containers to collect the
urine samples. The first part went for
chlamydia (PCR method), the second went for urinalysis and the third went for gonorrhea (culture). I don't know why they asked for 3 samples so basically the tests were done on beginning, mid and end parts of my urine.
This was done 3 weeks post exposure.
The results came out negative. What are the chances of these results being a false negative ?
