376 is very high for AST, enough that the number itself is the problem.
this is the average reading · make it yours below
This level is usually treated as urgent. A result this far outside the range is normally checked by a doctor promptly, not at your next routine appointment.
You are 335 U/L over the normal ceiling of 41. That reads very high.
376 is very high. That is above the normal range for AST. How much it matters depends on the markers it travels with, which is what the sections below are rewritten against.

Yes. 376 U/L is well outside the normal range for AST.
But a number alone is only half the story. Your Alanine Aminotransferase (ALT), Gamma-Glutamyl Transferase (GGT) and your risk factors decide how much it means. Tell it who you are.

Aspartate Aminotransferase (AST) 376 U/L might be considered significantly elevated. This value indicates a level that is higher than what is typically seen in many healthy individuals. When a reading like this appears, it's natural to have questions about what it means for your well-being. Let's explore what this number could indicate about your internal health and what steps might follow.
what this page cannot tell you
The AST/ALT ratio above 2:1 suggests alcoholic liver disease. Near 1:1 points to non-alcoholic fatty liver. Which is yours?
This page has not been given your ALT, so that half of the picture is missing here. It is describing the average reader with Aspartate Aminotransferase (AST), not you.
Read mine against my ALT →An Aspartate Aminotransferase (AST) level of 376 U/L is a critically elevated finding, signifying substantial acute cellular damage, most often within the liver or skeletal muscles. This value, over eight times the upper limit of the normal range, signals an urgent clinical situation.
At this pronounced level, likely causes include acute viral hepatitis, severe drug-induced liver injury, significant alcoholic hepatitis, or conditions causing extensive muscle breakdown such as rhabdomyolysis following trauma or certain medications.
To accurately diagnose the underlying issue, additional blood tests are routinely ordered, including Alanine Aminotransferase (ALT), bilirubin, alkaline phosphatase, and a creatine kinase (CK) level to help differentiate between liver and muscle origin.
Further investigations often involve specific viral hepatitis serologies, toxicology screenings for drug-induced injury, and potentially imaging of the abdomen, like an ultrasound. A critical detail for patients to understand is that the immediate priority is to identify the precise source of this acute insult; while concerning, many causes of such a dramatic AST elevation are identifiable and treatable, with potential for significant recovery once managed appropriately.
Expect a rapid succession of tests, sometimes initiated during the same visit, to pinpoint the origin of this elevated 376 U/L reading and guide immediate, targeted treatment strategies.
An elevated Aspartate Aminotransferase (AST) level, such as 376 U/L, often prompts questions about potential underlying health considerations. While AST is an enzyme found in various body tissues, a notable increase like this frequently points to irritation or injury in the liver or muscles.
Understanding these possibilities is the first step toward gaining clarity about your health. It is important to remember that this number is a piece of a larger health picture, and it rarely tells the full story on its own.
It serves as an indicator that warrants further attention and discussion with a healthcare professional to understand its specific meaning for you and any associated risks.

AST and ALP together distinguish between liver cell damage and cholestatic disease, which have completely different treatments.
This page has not been given your ALP, so it cannot tell you which of those you are. It is describing the average reader with Aspartate Aminotransferase (AST), not you.
Read mine against my ALP →A serum aspartate aminotransferase (AST) level significantly elevated to 376 U/L, which is over eight times the upper limit of normal, indicates substantial ongoing hepatocellular injury. At this magnitude of elevation, the liver's ability to perform its essential metabolic functions, such as protein synthesis and detoxification, is severely compromised.
This can rapidly lead to a cascade of complications, including impaired blood clotting due to reduced synthesis of clotting factors, and the potential development of hepatic encephalopathy if toxins like ammonia are not adequately cleared.
Furthermore, prolonged severe inflammation at this level can accelerate the progression of underlying liver disease towards fibrosis and cirrhosis, significantly increasing the long-term risk of liver failure and portal hypertension.

When your Aspartate Aminotransferase (AST) level reads 376 U/L, it's a signal that your body is communicating something important. Aspartate Aminotransferase is an enzyme, which is a type of protein that helps speed up chemical reactions in cells.
AST is normally present in cells throughout the body, including those in the liver, heart, skeletal muscles, kidneys, and brain. When these cells are damaged, AST can leak into the bloodstream, leading to higher levels in a measurement.
An Aspartate Aminotransferase (AST) 376 U/L reading suggests that there has been some degree of cell damage, most commonly in the liver, but also potentially in muscle tissue. For example, conditions that cause irritation or injury to liver cells, like certain forms of liver inflammation, can lead to such an elevation.
Similarly, damage to muscle cells, perhaps from strenuous physical activity or injury, might also contribute to a high AST value. Because AST is found in many places, pinpointing the exact source of this elevation often requires looking at other health markers and your overall health story.
This number, Aspartate Aminotransferase (AST) 376 U/L, is a starting point for further investigation to understand its root cause and what it implies for your health journey.
An AST level around 376 U/L strongly suggests acute hepatic insult rather than a chronic, slowly progressing issue. The most probable causes include a significant viral hepatitis infection, such as acute Hepatitis A or B, particularly if recently contracted.
Another highly plausible cause is acute drug-induced liver injury (DILI), stemming from a new medication, supplement, or even an overdose of an over-the-counter pain reliever like acetaminophen. Less commonly, but still a consideration, would be acute alcoholic hepatitis in an individual with a history of heavy alcohol consumption, or ischemic hepatitis due to severe systemic illness or shock, where the liver is deprived of oxygen.
Beyond what you eat, various lifestyle choices play a significant role in your overall health and can potentially influence markers like Aspartate Aminotransferase (AST) levels. When considering an elevated AST reading such as 376 U/L, focusing on holistic well-being can be empowering.
Regular physical activity, for instance, supports healthy body function, but it is important to note that very intense exercise can temporarily raise AST levels due to muscle activity. Balancing strenuous activity with adequate recovery is key.
Aim for moderate, consistent movement that feels good for your body. The quality of your sleep also has a profound impact on bodily repair and regeneration. Ensuring you get enough restful sleep each night allows your body to recover and maintain optimal function.
Managing stress effectively is another cornerstone of a healthy lifestyle. Chronic stress can affect various bodily systems, and finding healthy outlets like mindfulness, hobbies, or spending time in nature can contribute positively to your well-being.
Avoiding harmful substances, such as excessive alcohol consumption, is crucial because alcohol is a well-known contributor to liver stress, which can lead to elevated Aspartate Aminotransferase (AST) levels. While an Aspartate Aminotransferase (AST) 376 U/L requires professional attention, adopting a balanced lifestyle can be a supportive measure for your health journey.
Immediate medical evaluation is paramount for an AST result of 376 U/L. You should proceed directly to an emergency department or urgent care center for prompt assessment and potential admission.
Blood tests should be repeated to confirm the value and assess other liver enzymes like ALT and bilirubin. Comprehensive viral hepatitis serologies and toxicology screens are essential. Depending on the suspected cause, antiviral medications, discontinuation of offending drugs, or supportive care for alcoholic hepatitis may be initiated.
Lifestyle modifications, particularly strict alcohol abstinence and avoiding all over-the-counter medications unless cleared by a physician, are critical immediately.
