Hello there thank you for the question. It is apparent that you are worried about your condition. It is advisable to meet a physician as soon as possible. Since you have a negative blood test for chlamydia so it is confirmed that you are infected by another type of infections. There is a high possibility of gonorrhea infection.

So lets begin with what is causing gonorrhea. Gonorrhea is a sexually transmitted disease which is caused by bacterium Neisseria gonorrhoeae. Burning or painful sensation during urination is usually the first symptom in men. Other symptoms includes greater frequency or urgency of urination, a pus-like discharge from the penis which can be in white, yellow, beige, or greenish discharge, swelling or redness at the opening of the penis, swelling or pain in the testicle and a persistent sore throat.

There are many test you can do to confirm the infection of gonorrhea. As you have asked, urine PCR is more reliable as this tests find the DNA of gonorrhea bacteria. Because it searches for the bacteria’s genetic material, it is very unlikely that a false-positive test result will occur. As for the urethral smear, it is not as reliable and accurate as urine PCR. This tests requires a culture and takes a longer time compared to urine PCR.

It is important to treat the infection as it can cause future problems if it is not treated properly. Gonorrrhea can be treated with certain antibiotics such as azithromycin or ceftriaxone. It is also crucial to practice safe sex as well as get your partner treated as well. This infection can recur if both the partners are not treated completely.
