What color is your pee when your liver is failing?
Dark urine. Urine that is dark orange, amber, cola-coloured or brown can be a sign of liver disease. The colour is due to too much bilirubin building up because the liver isn't breaking it down normally.
What are signs that your liver is not functioning properly?
Liver failure occurs when your liver isn't working well enough to perform its functions (for example, manufacturing bile and ridding the body of harmful substances). Symptoms include nausea, loss of appetite, and blood in the stool. Treatments include avoiding alcohol and avoiding certain foods.
Does bilirubinuria cause dark urine?
Unconjugated bilirubin is soluble in fat but insoluble in water and thus cannot be renally excreted. Unconjugated hyperbilirubinemia is characterized by acholuric jaundice as urine is not darkened by urinary bilirubin as bilirubin is not detected in the urine in such cases.
What would cause high bilirubin?
Bilirubin passes through the liver and is eventually excreted out of the body. Higher than normal levels of bilirubin may indicate different types of liver or bile duct problems. Occasionally, higher bilirubin levels may be caused by an increased rate of destruction of red blood cells (hemolysis).

What are the chemical principles of ictotest?
CHEMICAL PRINCIPLES OF THE PROCEDURE: The reaction is based on the coupling of a unique solid diazonium salt with bilirubin in an acid medium to give the blue or purple reaction.# N#STORAGE AND HANDLING: Ictotest Reagent Tablets are stable until the expiration date in the unopened container if stored at temperatures between 15–30°C. Do not store the bottle in direct sunlight. Replace cap promptly and tightly after use. Do not use tablets that are damaged.#N#LIMITATIONS OF THE PROCEDURE: Metabolites of (phenazopyridine) give bright red-orange colors which may mask the reaction of small amounts of bilirubin. Elevated concentrations of urobilinogen do not mask the reaction of small amounts of bilirubin, but atypical orange colors are produced. Chlorpromazine in large amounts may give a false positive result, and metabolites of Lodine (etodolac) may cause false positive or atypical results.#N#SPECIFIC PERFORMANCE CHARACTERISTICS: Ictotest Reagent Tablets will detect as little as 0.05 to 0.1 mg bilirubin/dL in urine (0.9–1.7 µmol/L).

Is a dipstick a test for hematuria?
Dipstick Analysis: The accuracy of detecting microscopic hematuria, significant proteinuria, or urinary tract infection is a subject of much interest and practicality to emergency physicians. The urine dipstick has false-positive and false-negative results, and a list is presented in the table. It also should be noted that the commonly used urine dipstick has a finite lifespan, should be kept in a closed container, and should not be constantly exposed to air. Testing with outdated and improperly stored materials can lead to erroneous results. As an overview, dipstick testing is quite helpful, serving as a screening test for some conditions and a definitive test for others. In complicated cases or serious disease, dipstick testing must be correlated with microscopy and clinical parameters.
