[Question #3055] STI urine test

41 months ago
Sorry for the anxiety, but I have a follow-up question to another recent question I submitted to the forum. I recently got a negative result to a chlamydia/gonorrhea test. However, when I went to the urgent care clinic, they asked me for a urine sample prior to asking me what I was in for. As such, I had no instructions as to how to perform the test as I thought it was similar to many other urine tests I have done in the past. As a result, I did not necessarily “ catch the initial stream” and filled up a good portion of the cup. In reading this forum just now, I realized this might lead to an inaccurate result. Can you shed some light on likely accuracy of test and whether you think I should be tested again? I realize I am being overly paranoid but I am so worried about infecting my partner. Thank you again for your service.

The instructions regarding the volume of urine to be collected and that it be the initial portion of a void reflect the package instructions which, in turn, reflect the way the test was used when it was first evaluated.  Since then, other studies have shown that neither the volume of the specimen, nor when it is collected during urination meaningfully modify the results.  I would urge you to not worry.  EWH---
