Cause Of Clear Urine I Found Tiny White Particles In My Otherwise Clear, Light Yellow Urine. Is This Normal?

I found tiny white particles in my otherwise clear, light yellow urine. Is this normal? - cause of clear urine

Went for a simple urine test and he tested into the transparent container, I noticed these tiny particles floating in the white, very small, dim, light. I am a young, healthy woman, and I have to specify strange symptoms, infection or disease. No pain, no frequent urination, the smell does not irregular or discharge, no burning, etc. What could be the cause? Does it bother? Thank you!
