Jaundice 12.5 refers to a newborn jaundice value of 12.5 mg/dL. Because the value of jaundice in newborns varies with the time of birth, the normal value required varies at different times and stages. If the value reaches 12.5 mg/dL when the child starts to show jaundice 2-3 days after birth, it is a higher case and requires timely blue light exposure to avoid symptoms of bilirubin encephalopathy. If the value reaches 12.5 mg/dL at 4-5 days of life, it is more common in clinical practice, although it still exceeds the maximum peak value. Timely treatment, oral anti-yellowness medication as prescribed by the doctor, such as Yinjian Huang oral liquid, to ensure that the baby eats and poops more, to promote bowel movements and accelerate the regression of bilirubin, such cases are generally less serious and need not be particularly worried. Most physiological jaundice will gradually subside after 5-7 days of life, and the longest period of time will not exceed 2 weeks. If you are really worried, you can recheck your liver function after 2 weeks. If the jaundice continues to rise, it may be pathological jaundice, possibly hemolytic jaundice, or infectious hyperbilirubinemia, which requires prompt medical attention and symptomatic treatment under medical supervision to identify the cause.
