Jaundice or icterus is usually evident when the serum bilirubin level exceeds 2 5 mg dl. Total bilirubin direct and indirect range from about 0 2 to 1 2 mg dl some lab values range as high as 1 9 mg dl.
For those under 18 the.
Bilirubin lab value. In patients with hepatitis induced acute liver failure a serum total bilirubin level 17 5 mg dl 300 mmol l is a criterion for predicting death and the need for liver transplantation. Normal results for a total bilirubin test are 1 2 milligrams per deciliter mg dl for adults and usually 1 mg dl for those under 18. The approximate normal range of bilirubin in the blood serum is.
It moves to the intestines before being removed through your stool. These results may vary slightly from laboratory to laboratory. An adult who is over 18 years of age the total bilirubin normal range is 1 2 mg dl of blood.
Normal results for direct bilirubin are generally 0 3 mg dl. Normal values of total bilirubin are from 0 3 1 0 mg dl. Measuring bilirubin at the lab.
Scientists measure conjugated bilirubin and report it as direct bilirubin and measures total bilirubin values then calculated the unconjugated bilirubin by subtracting direct from total the result is the estimated indirect bilirubin unconjugated. Medical literature sources have minor variations in normal levels. While those under 18 tbil of 1mg dl is considered normal.
1 2 milligrams per deciliter mg dl for adults 1 mg dl for children under 18 years of age the skin normally becomes yellow once. The indirect bilirubin level in the bloodstream is the total bilirubin minus the direct bilirubin levels in the bloodstream. In comparison to the indirect the direct bilirubin normal value should be less than 0 3mg dl.
A small amount approximately 250 to 350 milligrams or about 4 milligrams per kilogram of body weight of bilirubin is produced daily in a normal healthy adult. An elevation greater than 20 mg dl suggests severe liver disease. Subtracting the direct bilirubin level from the total bilirubin level helps estimate the indirect level of unconjugated bilirubin.
For adults over 18 normal total bilirubin can be up to 1 2 milligrams per deciliter mg dl of blood. Normal values of direct bilirubin range from 0 to 0 4 mg dl.
