Amylase and Lipase Tests What does the test result mean? A high amylase level in the blood may indicate the presence of a condition affecting the pancreas. In acute pancreatitis, amylase in the blood often increases to 4 to 6 times higher than the highest reference value, sometimes called the upper limit of normal. The increase occurs within 4 to 8 hours of injury to the pancreas and generally remains elevated until the cause is successfully treated.

Reasons for Elevated Amylase and Lipase Amylase and lipase are digestive enzymes. Amylase breaks down dietary starch, and lipase aids in the digestion of dietary fats. The pancreas produces these enzymes in large quantities and secretes them into the small intestine. Diseases of the pancreas most commonly cause elevated amylase and lipase, although other disorders may lead to abnormally increased blood levels of these enzymes.

AA Amyloidosis AA Amyloidosis. AA amyloidosis occurs as a reaction to another illness, such as a chronic inflammatory disease or a chronic infection. Infections and inflammation cause the liver to produce a protein called SAA (serum amyloid A protein) in high levels. This is a normal reaction.

What are elevated liver enzymes? Elevated liver enzymes occur when there is damage or inflammation on the liver. The damage causes the liver cells to produce a higher amount of certain chemicals, which are deposited into the bloodstream. The liver enzymes that are usually elevated in the blood include alanine transaminase, or ALT, and aspartate transaminase, or AST.

- Quick Answer. According to MedicineNet, a high serum glutamic pyruvic transaminase, or SGPT, level indicates liver damage. SGPT is released into the bloodstream following injury to the liver. Normal values of SGPT range from 7 to 56 units per liter of serum. Continue Reading.

- Elevations in Alanine Transaminase (ALT) If an animal’s ALT level is elevated, it’s cause for concern. ALT is produced inside liver cells and the only way it can reach the bloodstream is through a ruptured cell. So an elevated ALT value (without elevation in other markers) may indicate rapid death of, or injury to, liver cells.

Liver Injury Caused by Drugs Many drugs (eg, statins) commonly cause asymptomatic elevation of hepatic enzymes (ALT, AST, alkaline phosphatase). However, clinically significant liver injury (eg, with jaundice, abdominal pain, or pruritus) or impaired liver function—ie, resulting in deficient protein synthesis (eg, with prolonged PT or with hypoalbuminemia)—is rare.

- By Mayo Clinic Staff. Elevated liver enzymes may indicate inflammation or damage to cells in the liver. Inflamed or injured liver cells leak higher than normal amounts of certain chemicals, including liver enzymes, into the bloodstream, which can result in elevated liver enzymes on blood tests. The specific elevated liver enzymes most commonly found are: Alanine transaminase (ALT) Aspartate transaminase (AST)

AMYLASE TEST Amylase is an enzyme that is normally present only in very low levels in the blood. Amylase, along with other enzymes, is produced by the pancreas to digest carbohydrates. It is released into the duodenum (the first part of the small intestines) in the digestive tract where it assists in food breakdown. Amylase is also produced by other organs in the body, particularly, the salivary glands.

However, since the liver has a huge. regenerative capacity and great functional. reserve, the magnitude of elevation in serum. ALT or AST is not indicative of the extent of. functional impairment and thus has limited.

Simply Stated: Elevated Enzymes When cells are damaged by disease or injury, large amounts of these leak out, causing blood tests to show that enzymes are elevated above normal. (You can roughly compare this situation to a car that's leaking oil. Leaks in many parts of the engine can have the same result: oil all over your driveway.)

Tumor Markers Lipase level increases within four to eight hours of acute pancreatitis, peaks at 24 hours, and remains elevated for one to two weeks, typically longer than amylase levels 1,3,4. Lipase is more sensitive and specific than amylase in diagnosing acute pancreatitis, with a negative predictive value of 94% to 100% 3,4.

A tumor marker ca 19-9 is usually elevated with pancreatic tumors. Depending on the location of tumor biliary enzymes could be elevated too.

Why is serum amylase level elevated in acute pancreatitis? In acute pancreatitis, serum amylase is usually elevated 3-fold and then returns to normal by 3-7 days. Patients with pancreatitis associated with hypertriglyceridemia or those with considerable acinar cell injury due to previous episodes of pancreatitis or chronic pancreatitis may not exhibit hyperamylasemia.

Amylase and Lipase Tests That means an elevated amylase level may indicate a problem, but a disorder unrelated to the pancreas may be the cause. Lipase tests are usually more specific than amylase for diseases of the pancreas, particularly for acute pancreatitis and for acute alcoholic pancreatitis.. With acute pancreatitis, there is usually no long-term damage and often no further problems develop. Chronic pancreatitis, which may present as a series of acute attacks or as an ongoing upset, can cause permanent damage.

Liver Blood Tests (Normal, Low, and High Ranges & Results) For example, AST level in serum is elevated in heart attacks or with muscle injury. It is therefore, not a highly specific indicator of liver injury as its elevation can occur as a result of other injured tissues. ALT (SGPT) is, by contrast, normally found largely in the liver. This is not to say that it is exclusively located in the liver, but that is where it is most concentrated. It is released into the bloodstream as the result of liver injury. Thus, it serves as a fairly specific indicator of liver status.

- Even if your test results are different from the normal value, you may not have a problem. To learn what the results mean for you, talk with your health care provider. The normal range for adults for amylase in a blood sample is 30 to 110 units per liter (U/L). If your amylase levels are higher than normal, you may have one of many conditions. These include: Sudden swelling of the pancreas (acute pancreatitis). Chronic pancreatitis that suddenly gets worse. Cancers of the pancreas, breast, colon, ovary, or lung. A sore in the pancreas.

- Elevated aminotransferase levels with acute hepatocellular injury: Drug-induced liver injury is designated hepatocellular if the ALT levels are increased to more than twice the upper limit of the reference range, with alkaline phosphatase levels that are within the reference range or are minimally elevated.ost drugs have a signature effect, which is a pattern of liver injury, although some drugs such as rifampin can cause all types of liver injury, including hepatocellular injury, cholestasis, or even isolated hyperbilirubinemia.

Acute pancreatitis 1 Serum lipase rises 4 to 8 hours from the onset of symptoms and normalizes within 7 to 14 days after treatment.  Serum amylase may be normal (in 10% of cases) for cases of acute or chronic pancreatitis (depleted acinar cell mass) and hypertriglyceridemia.
