Is it better to have low or high ALT?

Alanine aminotransferase or ALT (also known as SGPT) is an enzyme your body needs to break down proteins into energy. Most of it is found in the liver [1, 2]. ALT blood levels are a marker of liver health: low levels typically indicate a healthy liver, while high levels suggest liver damage [3].


Is it good to have low ALT?

Having a lower than normal ALT result is uncommon and usually isn't a cause for concern. However, a lower than normal ALT level could indicate a vitamin B6 deficiency or chronic kidney disease.

What is a good number for your ALT?

Normal Results. The normal range is 4 to 36 U/L. Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or may test different samples.


Is HIGH ALT good?

In general, high levels of ALT may be a sign of liver damage from hepatitis, infection, cirrhosis, liver cancer, or other liver diseases. The damage may also be from a lack of blood flow to the liver or certain medicines or poisons.

What level of ALT is concerning?

An ALT test result of >100 IU/l is a clear indicator of serious liver disease, but a mildly elevated ALT result (30–100 IU/l) is often ascribed to the use of medication (for example statins) or alcohol, obesity, or, for lower ALT levels (<50 IU/l), considered as part of the normal distribution of test results.

What level of ALT is liver failure?

ALT levels greater than 15 times the normal range indicate severe acute liver cell injury and evaluation should be initiated immediately. The differential diagnosis for patients with severe acute liver injury (ALT levels >15 times the normal range) is relatively limited.

What is the ALT level for fatty liver?

In a community-based study of 1346 Japanese patients with diagnostic criteria of NAFLD, the cutoff value of ALT for diagnosis of this disease was estimated to be 25 U/L in men and 17 U/L in women[39].

Can ALT levels go down?

People can lower their ALT levels by making lifestyle changes, such as taking regular exercise and changing their diet. Increasing fiber intake, reducing saturated fats and processed foods, as well as consuming a range of nutrients from fruits and vegetables may all help to lower levels.


Is HIGH ALT common?

Mild, asymptomatic elevations (less than five times the upper limit of normal) of alanine transaminase and aspartate transaminase levels are common in primary care. It is estimated that approximately 10% of the U.S. population has elevated transaminase levels.

Does High ALT mean diabetes?

Elevated levels of ALT, AST, GGT and ALP are related to a higher odds of diabetes. Also, increased serum levels of ALT, GGT and ALP even within normal range were independently related with the increased odds of diabetes.

What ALT level indicates cirrhosis?

A high Mayo Risk Score, and an AST:ALT ratio of >1.12 have been shown to be indicators of risk for the development of oesophageal varices. In PSC, as with other liver diseases, there are suggestions that an AST:ALT ratio of >1 indicates the development of cirrhosis.

Does low ALT mean liver damage?

ALT blood levels are a marker of liver health: low levels typically indicate a healthy liver, while high levels suggest liver damage [3]. The normal range is around 7-35 U/L in women and 7-40 U/L in men.

What is an unsafe ALT level?

What ALT level is considered high? The upper limit of normal for ALT is 55 IU/L. When an ALT level is double to triple the upper limit of normal, it is considered mildly elevated. Severely elevated ALT levels found in liver disease are often 50 times the upper limit of normal.


What can raise your ALT levels?

What is the most common cause of high ALT?

Chronic alcohol consumption, drugs, non-alcoholic steatohepatitis (NASH) and chronic viral hepatitis are common causes associated with raised ALT and AST. In chronic viral hepatitis, the elevation of liver enzyme may not correlate well with the degree of liver damage.


Can ALT levels change daily?
