Jaundice can be judged from the depth of urine color and the degree of yellowing of skin and sclera, but to know whether there is jaundice accurately, you need to go to the hospital for liver function test to judge whether there is jaundice according to the level of bilirubin. 1. Urine color: under normal circumstances, urine is light yellow, along with the higher degree of jaundice, the urine color will become darker and darker, and eventually show a thick brown or soy sauce color. 2. Skin and sclera color: To determine the severity of jaundice according to the skin color, make sure there is enough light, or choose fluorescent lamps and windows with good light transmission. Secondly, pay attention to the distribution of jaundice. Jaundice initially manifests itself in the sclera and face, which are slightly yellowish, and then develops to the trunk and lower limbs, further deteriorating. 3. Go to the hospital for liver function tests to determine whether jaundice exists according to the level of bilirubin. Whether jaundice is yellow or not can’t be judged by naked eyes, it is recommended to go to the hospital for venous blood test in time, and according to the result, the doctor will carry out standardized treatment.
