Bilirubin: Definition, Application, and Significance Hyperbilirubinemia is a condition defined as elevated serum or plasma bilirubin levels above the reference range of the laboratory, and it is due to disorders of bilirubin metabolism. Normal Ranges for Indirect Bilirubin in mg/dL: To calculate Indirect bilirubin easily, take Total Bilirubin level and subtract the Direct Bilirubin level from it. A 2018 study. Indirect bilirubin 0.8, 0.7, 0.6, 0.5,0.4, and 0.3 are all normal levels of blood bilirubin. It is normal to have some bilirubin in the blood. Bilirubin and related breakdown metabolites are well known for causing the characteristic coloring in bile and stool; however, its presence in the urine is not normal, and for it to be present there, it must be water . Bilirubin, Total and Direct, Neonatal | Test Detail | Quest Diagnostics What is a dangerous bilirubin level in adults - HealthTap [1] Approximately 80% of the bilirubin is derived from hemoglobin metabolism. The healthy range is clinically defined as less than 0.3 milligrams per deciliter (mg/dL) of direct bilirubin, with total levels between 0.1 and 0.2 mg/dL of direct bilirubin. suggests that low bilirubin levels could increase your risk of developing deep white matter lesions in your brain, even if you don't have any other health issues . 2 - 5 days. The normal range as traced in blood serum ranges between 0.2 mg/dL to 1 mg/dL. Normal levels of bilirubin may be present in uncomplicated Cirrhosis, early in the course of fulminant liver failure, or with hepatic metastases until the disease is advanced. My bloods are all normal just the Bilirubin level, I am waiting for Retest results then i will speak to my doctor. Bilirubin is measured in milligrams per deciliter (mg/dL). Lactate dehydrogenase (LDH) was 732 IU/L (normal range: 118-273 IU/L), serum alcohol level was < 3 mg/dL and urine toxicology was positive for opiates and methadone. The reference range may vary among laboratories. Normal Values: Total bilirubin = 0.3 to1.0 mg/dL or 5.1 to 17.0 mmol/L; Direct bilirubin = 0.1 to 0.3 mg/dL or 1.0 to 5.1 mmol/L; Indirect bilirubin (total bilirubin - direct bilirubin level) = 0.2-0.7 mg/dL; Raised level of direct bilirubin is seen in: Gallstones. Direct bilirubin: 0.0 to 0.3 mg/dL Generally, for older children and adults, the following ranges are considered normal: Total bilirubin: 0.3 to 1 milligrams per deciliter (mg/dL) Direct (conjugated) bilirubin: 0.1 to 0.3 mg/dL; In newborns, a normal value would be an indirect (unconjugated) bilirubin of below 8.7 mg/dL within the first 48 hours of birth. Hyperbilirubinemia, excess bilirubin in the blood, is an extremely common problem occurring during the newborn period. Bilirubin Direct. negative, +, ++, +++ Bilirubin levels in urine. Indirect bilirubin is the difference between total and direct bilirubin. A small amount of bilirubin in your blood is normal, but a high level may be a sign of liver disease. Reference ranges are dependent on many factors, including patient age, sex, sample population, and test method, and numeric test results can have different meanings in different laboratories. A normal level is: Direct (also called conjugated) bilirubin: less than 0.3 mg/dL (less than 5.1 µmol/L) Total bilirubin: 0.1 to 1.2 mg/dL (1.71 to 20.5 µmol/L) Click to see full answer. Normal Results. Bilirubin is measured in micromoles per litre (umol/L).
