Is 1.3 bilirubin seriously high?
Your Bilirubin total level of 1.3 is a High Bilirubin total level. If your Bilirubin total is in between 0.2 mg/dL and 1 mg/dL, then you need not worry as 0.2-1 mg/dL is the normal range for Bilirubin total. But if your Bilirubin total is lesser or greater than the above values, then there may be some problem in your body.
What is the normal range of bilirubin?
What should I know about bilirubin and blood test?
- Bilirubin is a reddish yellow pigment made during the normal breakdown of red blood cells.
- Normal levels vary slightly from lab to lab; they range from about 0.2 – 1.2 mg/dL.
- Signs and symptoms of high bilirubin levels in adults vary with the underlying cause; however, symptoms usually include jaundice and itching.
Why would total bilirubin be elevated?
In fact, bilirubin is what gives normal feces that brownish color. Bilirubin can be elevated for two reasons: too much production or not enough excretion. Too much production would be the result of a hemolytic pathology. That is too say, you are destroying way too many red blood cells and the body is digesting the heme into lots of bilirubin.
What is dangerous level of bilirubin in adults?
Normal level of circulating bilirubin is 0.2 to 1.2mg % in plasma. A bilirubin level of 5 mg % is considered as dangerous and need to be properly investigated to know the underlying pathology for excess bilirubin production in the body or defective and inefficient bilirubin excretion from the body in the form of further degradation product.
What is normal unconjugated bilirubin levels?
Values can vary slightly between labs, but the following ranges are considered normal for adults [2, 11]: Total bilirubin: 0.2 to 1.2 mg/dL. Direct (conjugated) bilirubin: less than 0.3 mg/dL. Indirect (unconjugated) bilirubin: about 0.2 to 1.2 mg/dL.
What happens if unconjugated bilirubin is high?
Elevated levels may indicate liver damage or disease. Higher than normal levels of direct bilirubin in your blood may indicate your liver isn't clearing bilirubin properly.
What is the normal range for direct and indirect bilirubin?
Normal findings Total bilirubin: 0.3-1.0 mg/dL or 5.1-17 μmol/L (SI units) Indirect bilirubin: 0.2-0.8 mg/dL or 3.4-12.0 μmol/L (SI units) Direct bilirubin: 0.1-0.3 mg/dL or 1.7-5.1 μmol/L (SI units)
What is the range for total bilirubin?
Typically, bilirubin levels fall somewhere between 0.3 and 1.0 milligrams per deciliter (mg/dL). Anything above 1.2 mg/dL is usually considered elevated.
How do you reduce unconjugated bilirubin?
Phenobarbital therapy has been shown to be effective in reducing plasma bilirubin levels in patients with Crigler-Najjar syndrome type 2. Administration of 60-180 mg/day of the drug (in divided doses) can reduce serum bilirubin levels by at least 25%. A response should be expected within 2-3 weeks.
At what level is bilirubin a concern?
The level of bilirubin that is harmful is around 20. Reaching a level this high is rare. High levels need to be treated with bili-lights.
What is high indirect bilirubin?
Indirect bilirubin is the difference between total and direct bilirubin. Common causes of higher indirect bilirubin include: Hemolytic anemia. This means your body is getting rid of too many red blood cells. Bleeding into the skin caused by injury.
What causes high indirect bilirubin?
Common causes of elevated indirect bilirubin include: Hemolytic anemia, or destruction of too many red blood cells. Bleeding into the skin caused by injury. Bleeding in the lung caused by a blood clot.
How is high indirect bilirubin treated?
For a few babies, the level of unconjugated or indirect bilirubin is so high (greater than 20-25 mg/dl) that physicians are concerned about brain damage. The level has to be brought down very fast using a technique called exchange transfusion. An exchange transfusion is performed in the neonatal intensive care unit.
What level of bilirubin causes jaundice?
Pathophysiology. The classic definition of jaundice is a serum bilirubin level greater than 2.5 to 3 mg per dL (42.8 to 51.3 μper L) in conjunction with a clinical picture of yellow skin and sclera.
Where is unconjugated bilirubin found?
Unconjugated bilirubin is transported across the sinusoidal membrane of the hepatocyte into the cytoplasm. Inside the hepatocyte, unconjugated bilirubin is bound by a cytoplasmic protein, in this case glutathione S-transferase.
How do you know if bilirubin is conjugated or unconjugated?
A urine test positive for bilirubin indicates conjugated hyperbilirubinemia. Conjugated bilirubin is soluble in water; therefore, it can be excreted via urine but not unconjugated bilirubin due to water insolubility.
What is the most common cause of unconjugated hyperbilirubinemia?
Hyperbilirubinemia in children is usually unconjugated and most often caused by problems with red blood cell stability and survival or by defects in the bilirubin-conjugating enzyme uridine diphosphoglucuronate glucuronosyltransferase (UGT).
What is the treatment for high bilirubin levels?
Treatments for elevated bilirubin in adults involves treating the cause and complications, such as: antibiotics to treat infection. corticosteroids to reduce liver inflammation. changing medications if they caused the elevated levels.
How does unconjugated bilirubin cause jaundice?
Pathophysiology of Jaundice Unconjugated bilirubin binds to albumin in the blood for transport to the liver, where it is taken up by hepatocytes and conjugated with glucuronic acid to make it water soluble. Conjugated bilirubin is excreted in bile into the duodenum.
What is the cause of high indirect bilirubin?
Common causes of higher indirect bilirubin include: Hemolytic anemia. This means your body is getting rid of too many red blood cells. Bleeding into the skin caused by injury.
Why do newborns have unconjugated hyperbilirubinemia?
Most of the newborn develops unconjugated hyperbilirubinemia (neonatal jaundice) because of hepatic immaturity and low activity of UGT1A1 during days 2 to 5. Breast milk feeding increases bilirubin levels in infants that result in maternal milk jaundice.
What is hyperbilirubinemia?
Introduction. 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. Depending on the form of bilirubin present in serum, hyperbilirubinemia can be further classified as unconjugated (indirect) or conjugated (direct).
How long does it take for jaundice to resolve?
In most cases of mild neonatal jaundice, no treatment is necessary, and it resolves on its own within a few weeks. In cases of moderate or severe jaundice (TB over 15 mg/dL), phototherapy is a safe option. During phototherapy, the infant’s skin is exposed to light in the blue-green spectrum in a way that transforms bilirubin into a water-soluble isomer and reduces its toxicity by increasing its elimination in both the urine and stool. It is crucial to maintain proper hydration and urine output during phototherapy. [10][15]
What causes bilirubin to increase?
Increased bilirubin production and consequential unconjugated hyperbilirubinemia can result from increased catabolic degradation of hemoglobin and other heme proteins, typically due to accelerated hemolysis , a large hematoma, dyserythropoiesis (e.g., megaloblastic and sideroblastic anemias), or sometimes due to destruction of transfused erythrocytes. In these conditions, patients with normal liver function efficiently conjugate and excrete the excess bilirubin. [2][9] As a result, the serum levels of unconjugated bilirubin remain modest (1 to 4 mg/dL) and rarely exceed 4 mg/dL. Prolonged hemolysis can lead to severe hyperbilirubinemia in patients with concurrent hepatic dysfunction.
How long does it take for jaundice to develop in neonates?
Approximately 50% of neonates present with physiologic jaundice during the first five days after birth. Nonphysiologic, Lucey-Driscoll syndrome, or maternal serum jaundice in neonates results from maternal serum during the initial four days after delivery. The onset of asymptomatic jaundice usually characterizes the overproduction of bilirubin due to ineffective erythropoiesis (ELB production). Patients with Gilbert syndrome are generally asymptomatic and present with mild or intermittent unconjugated hyperbilirubinemia without any liver disease or hemolysis, and on clinical examination may manifest jaundice. Some nonspecific symptoms, such as fatigue, abdominal cramps, and malaise, are commonly observed in this disease. Infants with Crigler-Najjar type I syndrome present jaundice in the first few days after birth with neurological sequelae if UCB is greater than 20 mg/dL. By the second week of an infant’s life, it rapidly progresses to life-threatening severe jaundice that requires treatment with exchange transfusion, intensive phototherapy, and liver transplantation. However, patients with Crigler-Najjar type II syndrome, are mostly asymptomatic and may rarely present with jaundice and kernicterus. During the physical examination, the color of the skin and sclerae should be examined carefully under light for the evaluation of jaundice. For example, in patients with mild jaundice or hyperbilirubinemia (2 to 3 mg/dL), only scleral icterus can be seen. Also, with hemolytic anemia, there might be anemia and splenomegaly.
What enzyme converts heme to bilirubin?
The conversion of heme to bilirubin is a two-step reaction, in the first step the microsomal heme oxygenase enzyme of the reticuloendothelial system, converts heme to biliverdin, which in turn is reduced to unconjugated bilirubin (UCB) by a second enzyme biliverdin reductase.[7] . The UCB is lipophilic.
How rare is Crigler-Najjar syndrome?
Crigler-Najjar syndrome is a very rare disease with less than fifty cases in the United States and approximately 1 case per million births worldwide.
What is the normal bilirubin level?
Normal levels vary slightly from lab to lab; they range from about 0.2 – 1.2 mg/dL. Signs and symptoms of high bilirubin levels in adults vary with the underlying cause; however, symptoms usually include jaundice and itching. High bilirubin levels in adults usually means that there may be an underlying problem involving the red blood cells, liver, ...
What is the prognosis for an adult with elevated bilirubin levels?
The prognosis in an adult with high bilirubin levels may range from good to poor, depending upon the underlying cause of the elevation. For example, most hepatitis A patients recover completely while patients with liver cancer or cirrhosis may have a poorer outcome.
What should I know about bilirubin and blood test?
Bilirubin is a reddish yellow pigment made during the normal breakdown of red blood cells.
What is bilirubin?
Bilirubin is a bile pigment that is orange-yellow in color. It is formed during the normal breakdown of red blood cells ( hemoglobin ), and is excreted in the bile. Bilirubin can be classified as indirect (free or unconjugated) while it is circulating and is considered as direct after conjugation in the liver with glucuronic acid.
What are the symptoms of high bilirubin levels in adults?
High bilirubin levels in adults may indicate several types of problems, for example:
How do I prepare for the bilirubin test?
In general, patients are often asked to fast (only drink water) for several hours before the test.
What do high bilirubin levels in a newborn mean?
High bilirubin levels in a newborn usually is the result of unconjugated bilirubin, and is not a major problem for many newborns because they soon metabolize the unconjugated bilirubin normally. These neonates usually clear jaundice within a week. However, very high unconjugated bilirubin levels over time (weeks) can be neurotoxic and can even cause death or lifelong neurological problems ( kernicterus) in those who survive. Newborn jaundice may be the result of an underlying problem, for example:
What is the condition called when bilirubin is elevated?
In Crigler-Najjar syndrome, at birth or in infancy the child show jaundice with Severe unconjugated hyperbilirubinemia, if bilirubin is extremely elevated can cause condition called kernicterus, the accumulation of unconjugated bilirubin in the brain and nerve tissues and lead to brain damage and death.
What is it called when you have high bilirubin levels?
High indirect bilirubin level with normal or slightly elevated direct bilirubin, commonly seen by those with excessive hemolytic anemia for any cause and newborn jaundice due to new birth immaturity or RH incompatibility between mother and baby, may be called hemolytic jaundice, for example:
What does it mean when your urine turns yellow?
The bilirubin shown in urine and skin at serum bilirubin levels between 3.0 to 5.0 mg/dl, skin jaundice and eyes yellowish discoloration appear, urine color become dark yellow or as light tea when direct bilirubin is high in the blood, when indirect bilirubin is higher than 25mg/dl in the blood, it may show greenish plasma color as a result of sever elevation of indirect bilirubin (due to increased activity of biliverdin reductase enzyme which reduce biliverdin to bilirubin).

How to calculate indirect bilirubin?
Indirect bilirubin is calculated from direct and total figures, where indirect = total minus direct bilirubin. As such, the normal range given for indirect bilirubin is generally the same or very slightly lower than for total bilirubin.
What is Bilirubin?
Bilirubin is a yellow compound produced during the normal breakdown of hemoglobin, the compound in red blood cells that allows them to carry oxygen. As red blood cells are broken down, the iron -containing part of hemoglobin (heme) is converted to bilirubin [ 1 ].
What enzyme converts bilirubin into bilirubin?
The UGT1A1 enzyme, which converts indirect bilirubin into direct bilirubin, is well-developed in the adult liver, but not in the livers of newborns. This is why jaundice with high indirect bilirubin is common in babies [ 2 ].
What does it mean when your bilirubin is high?
High Direct Bilirubin Levels. A high direct bilirubin often means that your body has a harder time removing bilirubin, either due to a liver problem, or blocked bile ducts. However, a result that’s higher than normal, doesn’t necessarily mean that you have a health condition needing treatment.
Why does bilirubin increase?
Indirect (unconjugated) bilirubin levels can increase due to: Gilbert’s syndrome. This benign syndrome is due to an inherited gene mutation that mildly increases bilirubin levels. Up to 16 % of all people have this syndrome. Bilirubin levels may spike when exposed to stress [ 15, 16] Strenuous exercise.
What is the primary gene responsible for the breakdown of bilirubin?
The primary gene responsible for the breakdown of bilirubin is UGT1A1, and variations in this gene determine how fast it is broken down. In Gilbert syndrome, which affects around 10% of the population, variants in UGT1A1 make the enzyme less efficient and cause moderate increases in indirect bilirubin levels [ 2 ].
What is the normal bilirubin level?
Normal results for direct bilirubin are generally 0.3 mg/dL. These results may vary slightly from laboratory to laboratory. Normal results may be slightly different for women and children, and results may be affected by certain foods, medications or strenuous exercise.
How to check bilirubin levels?
Bilirubin testing is usually done as part of a group of tests to check the health of your liver. Bilirubin testing may be done to: 1 Investigate jaundice — a yellowing of the skin and eyes caused by elevated levels of bilirubin. A common use of this test is to measure bilirubin levels in newborns to check for infant jaundice. 2 Determine whether there might be blockage in your bile ducts, in either the liver or the gallbladder. 3 Help detect liver disease, particularly hepatitis, or monitor its progression. 4 Help evaluate anemia caused by the destruction of red blood cells. 5 Help follow how a treatment is working. 6 Help evaluate a suspected drug toxicity.
How to know if a bilirubin needle is inserted?
Blood for bilirubin testing in newborns is usually obtained using a sharp lancet to break the skin of the heel (heel stick). There may be slight bruising at the puncture site afterward.
Why is bilirubin high?
Occasionally, higher bilirubin levels may be caused by an increased rate of destruction of red blood cells (hemolysis).
Why is bilirubin elevated?
One common, and harmless, cause of elevated bilirubin is Gilbert's syndrome, a deficiency in an enzyme that helps break down bilirubin. Your doctor may order further tests to investigate your condition. Bilirubin test results also may be used to monitor the progression of certain conditions, such as jaundice.
How to test for bilirubin?
Bilirubin testing is done using a blood sample. Usually, the blood is drawn through a small needle inserted into a vein in the bend of your arm. A small tube is attached to the needle to collect the blood.
Why do you need bilirubin test?

Why is bilirubin used in poop?
It’s used to help find the cause of health conditions like jaundice, anemia, and liver disease. Bilirubin is an orange-yellow pigment that occurs normally when part of your red blood cells break down. Your liver takes the bilirubin from your blood and changes its chemical make-up so that most of it is passed through your poop as bile. ...
Where does bilirubin travel?
It travels in the blood to the liver. Conjugated (“direct”) bilirubin. This is the bilirubin once it reaches the liver and undergoes a chemical change. It moves to the intestines before being removed through your stool. For adults over 18, normal total bilirubin can be up to 1.2 milligrams per deciliter (mg/dl) of blood.
