How to diagnose jaundice causing yellow urine like strong tea?

The prominent symptoms of jaundice hepatitis B are general fatigue and weakness, loss of appetite, nausea, vomiting, especially aversion to greasy food, upper abdominal congestion and fullness, and yellow urine resembling strong tea water. It may be caused by excessive bilirubin in the blood due to liver disease or hemoglobinuria due to intravascular hemolysis (e.g., paroxysmal sleep hemoglobinuria). The diagnosis can be confirmed by examination of liver function in the former case, and in the latter case: laboratory tests: acidified serum hemolysis test (Ham test), sugar water test, snake venom factor hemolysis test, urine occult blood or urine iron-containing hemoglobin. Diagnosis of jaundiced hepatitis B resulting in yellow urine resembling strong tea: 1. Fever Viral hepatitis often has low fever before the appearance of jaundice, and high fever may occur in a few cases. Cholangitis fever, generally above moderate, is often accompanied by chills and often occurs after severe epigastric cramps, followed by jaundice. Hepatocellular carcinoma often has fever due to necrosis of cancerous tissue or secondary infection. 2. abdominal pain when the liver area is hidden pain or distension, often suggests viral hepatitis, persistent distension is seen in chronic hepatitis and liver cancer; gallstones or biliary ascariasis attacks, often with paroxysmal colic in the right upper abdomen, there are a few gallstone patients can be no obvious history of abdominal pain; epigastric and low back pain suggests pancreatic head cancer. 3. indigestion viral hepatitis in the first week or so of jaundice often has Indigestion. If jaundice occurs before a longer period of dyspepsia, especially in elderly patients, the first consideration should be tumor. Long-term aversion to greasy diet or after eating oily food easily induced right upper abdominal discomfort or colic, common in chronic gallbladder disease. 4, skin itchy obstructive jaundice often has obvious itchy skin cancer (skin cancer [translation]: refers to malignant tumors occurring in the skin epidermis, there are basal cell carcinoma and squamous cell carcinoma. It mostly occurs in exposed parts of the body, such as head, face, neck and back of hands, accounting for about 81.1% of the total incidence. The occurrence of skin cancer is related to long-term sun exposure, X-ray and thermal radiation, frequent exposure to chemical substances such as petroleum, asphalt, arsenic and tar, long-lasting ulcers, etc.) In hepatocellular jaundice, there can also be mild disease itch; in hemolytic jaundice, there is no epidemic itch.5. Weight changes in cholestatic jaundice caused by cancer, weight loss is progressive; in patients with hepatocellular jaundice, weight loss is relatively insignificant.6. Urine and fecal color changes in cholestatic jaundice when the urine is like strong tea and the feces are light gray or terra cotta colored. In hepatocellular yellow colonization, the urine color deepens, the color is light yellow, and in cholestatic hepatitis, the feces can also be clay-colored. In acute attacks of hemolytic jaundice, soy sauce-colored urine and dark feces may be excreted.
