Bilirubin Blood Test In a newborn, higher bilirubin is normal due to the stress of birth. Normal bilirubin in a newborn would be under 5 mg/dL, but up to 60 percent of newborns have some kind of jaundice and bilirubin levels above 5 mg/dL.f bilirubin is not being attached to sugars (conjugated) in the liver and/or is not being adequately removed from the blood, it can mean that there is damage to your liver. Testing for bilirubin in the blood is therefore a good test of damage to your liver.

- Reference Range. Bilirubin is a tetrapyrrole and a breakdown product of heme catabolism. Most bilirubin (70%-90%) is derived from hemoglobin degradation and, to a lesser extent, from other hemo proteins. In the serum, bilirubin is usually measured as both direct bilirubin (DBil) and total-value bilirubin (TBil).

Overview Higher than normal levels of direct bilirubin in your blood may indicate your liver isn't clearing bilirubin properly. Elevated levels of indirect bilirubin may indicate other problems. One common, and harmless, cause of elevated bilirubin is Gilbert's syndrome, a deficiency in an enzyme that helps break down bilirubin.igher than normal levels of direct bilirubin in your blood may indicate your liver isn't clearing bilirubin properly.

Bilirubin Chart For Adults In order to analyze of the bilirubin levels in adults are normal or not, the doctor will need to look at the values of all three, direct bilirubin, indirect bilirubin and total bilirubin. Given below is the normal bilirubin range in adults: 1  Direct bilirubin: 0.1 mg/ dl to 0.3 mg/ dl (1.7 mmol/ l to 5.1 mmol/ l).he normal levels for bilirubin in children are completely different, as compared to the bilirubin levels in adults. Hence, in case of babies and infants, instead of referring to a bilirubin chart for adults, doctors should use a chart for babies.

Overview Bilirubin test results are expressed as direct, indirect or total bilirubin. Total is a combination of direct and indirect bilirubin. Typically, you'll get results for direct and total bilirubin.Normal results for a bilirubin test are 1.2 milligrams per deciliter (mg/dL) of total bilirubin for adults, and usually 1 mg/dL for those under 18.Normal results for direct bilirubin are generally 0.3 mg/dL. These results may vary slightly from laboratory to laboratory.ormal results for a bilirubin test are 1.2 milligrams per deciliter (mg/dL) of total bilirubin for adults, and usually 1 mg/dL for those under 18.

Bilirubin - Blood Bilirubin is a yellowish pigment found in bile, a fluid made by the liver. This article discusses the laboratory test that is done to measure bilirubin in the blood. A small amount of older red blood cells are replaced by new blood cells every day. Bilirubin is left after these older blood cells are removed.

Jaundice If bilirubin levels in babies are very high for too long a type of brain damage, known as kernicterus, may occur. Causes of jaundice vary from non-serious to potentially fatal. Levels of bilirubin in blood are normally below 1.0 mg/dL (17 µmol/L) and levels over 2–3 mg/dL (34-51 µmol/L) typically results in jaundice.

Bilirubin A bilirubin test is used to detect an increased level in the blood. It may be used to help determine the cause of jaundice and/or help diagnose conditions such as liver disease, hemolytic anemia, and blockage of the bile ducts.f the total bilirubin level is increased, the laboratory can use a second chemical test to detect water-soluble forms of bilirubin, called direct bilirubin. The direct bilirubin test provides an estimate of the amount of conjugated bilirubin present.

Dark Urine?kirk8 Apr 18, 2014 A bilirubin test measures the amount of bilirubin in a blood sample. Bilirubin is a brownish yellow substance found in bile. It is produced when the liver breaks down old red blood cells. Bilirubin is then removed from the body through the stool (feces) and gives stool its normal color. Bilirubin circulates in the bloodstream in two forms:

Reference Range Indirect bilirubin correlates with unconjugated bilirubin but tends to underestimate unconjugated bilirubin, as a portion of the unconjugated bilirubin reacts with diazosulfanilic acid, producing azobilirubin, which is measured as direct bilirubin. The reference range of total bilirubin is 0.2-1.2 mg/dL.

Bilirubin A bilirubin test is used to detect an increased level in the blood. It may be used to help determine the cause of jaundice and/or help diagnose conditions such as liver disease, hemolytic anemia, and blockage of the bile ducts.ilirubin is ultimately processed by the liver to allow its elimination from the body. Any condition that accelerates the breakdown of RBCs or affects the processing and elimination of bilirubin may cause an elevated blood level.
