Total bilirubin normal range

Total Bilirubin (Blood) Does this test have other names? Total serum bilirubin, TSB What is this test? This is a blood test that measures the amount of a substance called bilirubin. This test is used to find out how well your liver is working. It is often part of a panel of tests that measure liver function. A small amount of bilirubin in your blood is normal, but a high level may be a sign of liver disease. The liver makes bile to help you digest food, and bile contains bilirubin. Most bilirubin comes from the body's normal process of breaking down old red blood cells. A healthy liver can normally get rid of bilirubin. But when you have liver problems, bilirubin can build up in your body to unhealthy levels. Why do I need this test? You may need this test if you have symptoms of liver damage or disease. Symptoms include: • Yellowish skin or eyes (jaundice) • Stomach pain • Dark urine • Light colored stool • Flu-like symptoms, such as fever and chills You may also have your bilirubin level tested regularly if you are being treated for liver disease. Many healthy newborns also develop jaundice.Most jaundice in babies causes no problems. But babies are often tested shortly after birth because a high bilirubin levelmay affect the brain, lead to deafness, and cause intellectual or developmental disabilities. What other tests might I have along with this test? You may have other blood tests to find the cause of your liver problems. You may also have urine tests, an ultrasound o...

Overview What is bilirubin? Bilirubin is a byproduct of broken-down old What is a bilirubin blood test? A bilirubin blood test measures bilirubin levels in your blood. A healthcare provider draws a small sample of your blood from a vein and sends it to a lab to analyze. The lab will measure your bilirubin levels to determine whether they’re in the normal range. High or low bilirubin levels might indicate that some part of the process of breaking down and clearing old red blood cells isn’t working correctly. What do bilirubin levels in your blood indicate? Healthcare providers often give bilirubin tests to check on the health of your liver. The bilirubin test is one of a comprehensive panel of What causes high bilirubin levels (hyperbilirubinemia)? Bilirubin might build up in your blood if: • Your body breaks down too many red blood cells too fast. You might be overproducing bilirubin if you have a • Your liver is struggling to process its normal load of bilirubin. Your liver might struggle with occasional toxic overload, or it might have a chronic • Your biliary system isn’t clearing bile efficiently. There might be a blockage in your What causes low bilirubin levels (hypobilirubinemia)? Certain medications can lower your bilirubin levels, including What does bilirubin do in your body? Bilirubin is a waste product of expired red blood cells. Normally, your body expels it through your intestines. On its way out, though, it may provide some benefits. Current studies suggest ...

• Hemolytic anemia: When red blood cells are rapidly destroyed, often as a result of cancer (such as leukemia or lymphoma), autoimmune diseases (like lupus), or medications (such as acetaminophen, ibuprofen, interferon, and penicillin), it can cause high bilirubin levels. • A lack of digestive bacteria in newborns: This can cause jaundice in newborns due to impaired breakdown of bilirubin. • Gilbert syndrome: This is a genetic disorder that causes the liver to process bilirubin slowly. • Liver disease: This can occur if the liver is not functioning as it should. Red blood cells last about 120 days in the bloodstream. The body normally produces bilirubin as a by-product of the breakdown of red blood cells when they're old or have become damaged, so the bloodstream always has some bilirubin in it. What Medications Cause High Bilirubin? Some drugs can impair liver function and cause high bilirubin levels. This can be due to underlying liver problems or the result of prolonged use or overuse. • Bleeding under the scalp from a difficult delivery • Cystic fibrosis • Enzyme deficiencies • A genetic or inherited disorder • Hepatitis • Higher levels of red blood cells • An infection, such as rubella, syphilis, or sepsis • Low oxygen levels • Mismatched blood type between mother and baby, such as Rh incompatibility or ABO incompatibility • Sickle cell anemia In newborns, a bilirubin level above 25 mg/dL is considered dangerously high. This is because excess unconjugated bilirubin ca...

A small amount of older red blood cells are replaced by new blood cells every day. Bilirubin is left in the blood after these older blood cells are removed. The liver helps break down bilirubin so that it can be removed from the body in the stool. A level of bilirubin in the blood of 2.0 mg/dL can create Jaundice is the most common reason to check bilirubin level. The test will likely be ordered when: • The provider is concerned about a newborn's jaundice (most newborns have some jaundice) • Jaundice develops in older infants, children, and adults A bilirubin test is also ordered when the provider suspects a person has liver or gallbladder problems. It is normal to have some bilirubin in the blood. 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) Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or may test different samples. Talk to your provider about the meaning of your specific test results. In newborns, bilirubin level is higher for the first few days of life. Your child's provider must consider the following when deciding whether your baby's bilirubin level is too high: • How fast the level has been rising • Whether the baby was born early • The baby's age Jaundice can also occur when more red blood cells than normal are broken down. This can be caused by: • A blood disorder called • A red blood cel...

Overview A bilirubin test measures the levels of bilirubin in your blood. Bilirubin (bil-ih-ROO-bin) is a yellowish pigment that is made during the breakdown of red blood cells. Bilirubin passes through the liver and is eventually excreted out of the body. Higher than usual levels of bilirubin may indicate different types of liver or bile duct problems. Sometimes, higher bilirubin levels may be caused by an increased rate of destruction of red blood cells. Why it's done Bilirubin testing is usually one of a group of tests to check the health of your liver. Bilirubin testing may be done to: • Investigate jaundice — a yellowing of the skin and eyes caused by high levels of bilirubin. This test is commonly used to measure bilirubin levels in newborns with infant jaundice. • Determine whether there might be blockage in your bile ducts, in either the liver or the gallbladder. • Help detect liver disease, particularly hepatitis, or monitor its progression. • Help evaluate anemia caused by the destruction of red blood cells. • Help follow how a treatment is working. • Help evaluate a suspected drug toxicity. Some common tests that might be done at the same time as bilirubin testing include: • Liver function tests. Blood tests that measure certain enzymes or proteins in your blood. • Albumin and total protein. Levels of albumin — a protein made by the liver — and total protein show how well your liver is making certain proteins. These proteins are necessary for your body to fight ...

Share on Pinterest Russell Monk/Getty Images This disorder is easily recognizable due to a yellowing of the skin and eyes. High bilirubin levels can occur in adults, but the disorder is more common in newborns. This is because it takes some time after birth for an infant to start efficiently metabolizing bilirubin and excreting it in their stool. The approximate normal range of bilirubin in the blood is less than The skin normally becomes yellow once levels reach 2–3 mg/dL. Any person who experiences yellowing of the skin or eyes should see a doctor. It may be a sign of a serious condition. The breakdown of The RBCs have a lifespan of around Once in the liver, bilirubin becomes “conjugated.” This means it is water-soluble and the body can excrete it. Unconjugated bilirubin is toxic. Conjugated bilirubin is usually not because it can come out of the body, as long as nothing is interfering with its removal. A high level of bilirubin in the blood is known as hyperbilirubinemia. High bilirubin levels can cause jaundice. Jaundice makes the skin and the whites of the eyes A doctor can usually detect a person’s bilirubin levels through a blood test. While every laboratory may have slightly different reference ranges, the following values approximately represent normal bilirubin levels based on age. A doctor There are several conditions that can cause high bilirubin levels either before reaching the liver, after leaving the liver or within the liver itself. Before reaching the liv...

Bilirubin is a yellowish substance in your blood. It forms after red blood cells break down, and it travels through your liver, gallbladder, and digestive tract before being excreted. The condition of having high bilirubin levels is called hyperbilirubinemia. It’s usually a sign of an underlying condition, so it’s important to follow up with a doctor if test results show you have high bilirubin. It’s also a common temporary condition in newborns. Read on to learn more about the symptoms of high bilirubin and what can cause it. Healthy vs. high bilirubin levels 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. Having high bilirubin can be a sign of several conditions. Your doctor will take your symptoms, as well as any other test results, into account to help narrow down a diagnosis. Gallstones Symptoms of gallstones include: • pain in your upper right abdomen or right below your chest • back pain between your shoulders or in your right shoulder • feeling sick • throwing up Gallstones may form if your body is already producing too much bilirubin due to a liver condition or if your liver is creating too much cholesterol. They can also be a complication of an infection of your bile ducts or from a blood disorder. Bilirubin builds up when your gallbladder is blocked and can’t drain properly. Gilbert’s syndrome This condition often doesn’t cause symptoms, but when it does, th...
