Does urine routine and culture as well as kub ultrasound detect pregnancy or std?

See below. Pregnancy is detected by a specialized urine or blood test for hcg. It is verified by ultrasound. Kub or ua & culture are of no use for pregnancy detection. Stds are detected by cultures specifically for a suspected infection. Trichomonas can be picked up in a ua. A general urine culture will not pick up most stds. A kub or us will not detect stds - just nonspecific effects on internal organs.
