Urology/urine test


last week my doctor gave me a plastic cup and told me to fill it up with urine.i filled plastic cup with urine and sealed the cap tighty.due to my c carlessness  theurine sample fell out of my hand and fell to urine leaked out of plastic container but it was really formy.could this effect accuracy of test in picking up protein,albumin,or blood in urine.also how accurate is dipstick in picking up albumin and blood in urine


Dropping the cup would have no effect on the chemical tests.  Likewise, no assumptions can necessarily be made about the fact that it might have appeared "foamy".  Urine dipstick tests are quite sensitive on protein and blood in the urine, but they are only "yes or no" types of tests.  A more accurate test is usually done next if the dipstick is positive.
