I just had a urine test done it says protein ua is 2+ is that normal? i'm 19 years old?

No, it is abnormal and you need to have a formal urinalysis done along with a urine protein quantitative test, i.e. urine protein/creatinine.

If it was mid-stream urine then 2+ protein is not normal. Since it is not uncommon for urine to get contaminated with vaginal secretions, you may wish to repeat the test with a clean catch.
