Q:

What does a low ALT and AST signify?

A:

Quick Answer

Low levels of ALT and AST are commonly found in adult blood tests and are normal for most people. These lower levels are good because they indicate that the liver, heart, pancreas and kidneys are functioning properly and releasing small amounts of the enzymes. It is when the levels start to climb that doctors become concerned about the health of a patient.

When a doctor draws blood to complete an ALT and AST test, they typically look for indicators that something is malfunctioning within the body. Most doctors complete these two tests at the same time because they offer a better ratio for comparison. With these numbers, the doctor can determine the extent of any damage, which allows them to develop a treatment plan. Unlike other enzymes found in the blood, lower levels of ALT and AST are a positive result. If the numbers change between visits, the doctor completes the test over again in a few hours. Since these levels can change drastically within a 6 to 10 hour time span, most physicians need to pay close attention to lab results. For this reason, most doctors choose to run each test multiple times a year for anyone who has a history of infection or illness related to the liver, heart or kidneys.

  • Q:

    How do you reduce elevated ALT and AST levels?

    A:

    Reducing ALT or AST level is not possible in most cases, as elevated ALT levels normally indicate liver damage and elevated AST levels indicate tissue damage or damage to an organ such as the brain or heart, states WebMD. AST generally decreases on its own after injury, within days.

    What is the way for a person sleep less?

    A:

    It would be highly improbably for most people to be able to get by on sleeping less and not suffer any consequences. Chronic sleeplessness and sleep deprivation has been linked to a number of medical conditions such as diabetes, obesity, cardiovascular problems, hypertension, stroke and depression. These findings were the results of a study about sleep deprivation and sleep disorders, which was published in 2006 in the National Academies Press.

    What does ALT (SGPT) mean in a blood test?

    A:

    The ALT test checks the level of alanine aminotransferase in the blood to see if the liver is healthy. Elevated levels of the enzyme could indicate damage caused by trauma or a disease process, such as cirrhosis or a strain of hepatitis, as stated by WebMD.
