I have been having Uti like symptoms, which I'm used too

Customer Question

I have been having Uti like symptoms, which I'm used too having sometimes. So I took some antibiotics for it that I had in my house. 4 doses worth. I go in to get tested for Uti shows negative. They also run std test which comes back negative. However couple months later feel same way. Uti again shows negative! Could those antibiotics I was on show std test false negative cause I took them?

The antibiotics I took 4 pills of were not what cures std but my normal Uti pills. Had left over. I was still showing symptoms and that's why I came in for Uti and std test. Both showed positive

Customer: replied 1 year ago.
Several Utis past two years or what feel like them past two years. , last 3 uti test and culture shows negative. They are getting worse and more frequent. Pressure n pain,
Feels like need to pee, urgency. The pills I took were some brand of antibiotics giving for Utis. I took 4 just to feel better before doctor could get me in

I'm wondering if it sounds like std but maybe culture and swab showed negative on accident due to me pre taking pills for possible Uti??

When did you finish the pills & get the tests?

Customer: replied 1 year ago.
I only took 4 of the pills for Uti then went in and got swabbed and tested thinking I had Uti. Then got the call 5 days later that std and Uti negative.
Customer: replied 1 year ago.
Could 4 Uti pills effect swab and pee test to where it shows negative? Or does it sound like I have something else
Customer: replied 1 year ago.
They were not pills to cure std just Utis

Thank you for all the information,

Antibiotic taken before test may cause false negative tests.

But it would not cause negative results on every occasion.

It is likely that you are not having UTI or STD if repeated tests are negative.

There can be other causes besides an infection.

There can be urethral syndrome.

You can read about this in this link.

You can take an evaluation by urologist.

I hope this information helps.
If there’s anything else I can do, please let me know.
If you are satisfied, please rate my answer as good or excellent.

I've only taken the std test once. How sure will it effect the swab test?
Customer: replied 1 year ago.
Those 4 pills
Customer: replied 1 year ago.
Like is it a big chance
Expert:  Dr. Saha replied 1 year ago.

Please write the name of the pill.

How many days after the last pill did you have the test?

Customer: replied 1 year ago.
I took two macrobid pills day 1, day 2 two macrobid pills, day 3 went to doctor telling them not feeling well still after taking Uti pills. They swab texted my vagina n pee tested me. All tests show negative. The lab showed negative for gonnarea and clamydia when they called me 5 days later
Customer: replied 1 year ago.
The Uti tests keep coming up negative but that's the only std test I had which was swab n pee
Customer: replied 1 year ago.
Only sex with two ppl too in two years
Expert:  Dr. Saha replied 1 year ago.

Macrobid will act against E coli, Klebsiella etc.

This is not usually used for gonorrhea or chlamydia.

So those infections are unlikely to be present in your case.

Ok thank you! So you don't think that would of effected the test in anyway due to the nature of the medicine? Just making sure... Thanks again

That's my Last question
Expert:  Dr. Saha replied 1 year ago.

That medicine would not affect STD tests but may affect UTI test.
