[|Human|] My son went to an urgent care with a bout of vomiting and diarrhea . He went just to get a slip to return to work. They did a urinalysis and said he had 3+ bilirubin in his urine and need further testing. They recommended going to ED, however there was more than a 4 hour wait. What is the possible cause and how soon should further testing be done. Oh.... he is 21yo and otherwise in good health
[|AI|]  Hi and welcome to Chat Doctor. It sounds like typical biliary colic caused by gallbladder stones. It isn't very often in his age but definitely can be found. Other reason for it are acute hepatitis(alcoholic, toxic or viral). This isn't emergency if his symptoms doesn't progress, but it should be evaluated and ultrasounds and basic blood gets should be done. If he experiences repeated pain, vomiting and fever he must go to ER.
