I felt like I should provide an update here since there are so many helpful replies. I never got the STD tests done. About a year later the lab found a similar trace of urine as well as some protein and I was referred to nephrologist. After many many tests and visits finally I am told I probably have a harmless version of igAN (the type of it that doesn’t affect kidney severely and patients can lead normal life). Coincidentally both the labs I did were right after I had flu and it’s normal to find some blood and protein in urine when you have an infection. I got the tests done when I’m healthy and it comes clean
