167 is elevated for AST, far enough out to be worth acting on.
this is the average reading · make it yours below
This is outside the range. Worth acting on, and worth seeing next to your other numbers first: the same value means different things depending on what is around it.
You are 126 U/L over the normal ceiling of 41. That reads elevated.
167 is elevated. 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.

Borderline. 167 U/L is 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) 167 U/L might be considered higher than what is typically observed for many adults. This specific value suggests your body could be communicating important information about your internal well-being.
Understanding this elevated level is a crucial step towards uncovering potential insights about various bodily processes. This initial information can help you feel more prepared for discussions with your healthcare team.
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 AST level of 167 U/L represents a significant elevation well above the normal range of 5-40 U/L, indicating cellular damage. While Aspartate Aminotransferase is commonly associated with liver function, this specific moderate increase often points to early or mild-to-moderate liver inflammation.
Common culprits at this level include acute viral hepatitis, non-alcoholic fatty liver disease (NASH), or reactions to certain medications. However, a value of 167 U/L doesn't exclusively signal liver disease; AST is also abundant in skeletal muscle and the heart.
Therefore, recent strenuous exercise, muscle trauma, or even a minor cardiac event can transiently raise this marker, an important distinction many patients might not realize. To accurately identify the source of this elevation, your healthcare provider will typically order companion tests such as Alanine Aminotransferase (ALT), which is more liver-specific, along with other liver function markers like bilirubin and alkaline phosphatase.
Further evaluation might include hepatitis panels, an abdominal ultrasound, or a detailed review of your medication list and recent physical activity to determine the precise underlying cause and guide appropriate management.
An elevated Aspartate Aminotransferase (AST) 167 U/L level can sometimes suggest underlying issues that warrant further exploration, even if you are not experiencing noticeable symptoms. This enzyme is present in several areas of the body, including the liver, heart, skeletal muscles, and kidneys, so a higher level often points to some form of cellular activity or distress in these areas.
While one isolated number doesn't tell the whole story, it acts as an important signal, prompting a closer look into your overall health picture. It’s a call to understand the subtle shifts happening within your system, inviting you to engage more deeply with your healthcare journey.
what this page cannot tell you
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 →An AST level of 167 U/L, significantly exceeding the normal range, suggests active hepatocellular injury that, if unaddressed, could progress to more severe liver dysfunction. This elevation indicates that liver cells are releasing substantial amounts of AST into the bloodstream, pointing towards inflammation or damage.
While this specific elevation doesn't definitively predict immediate decompensation, sustained damage at this magnitude increases the risk of developing fibrosis, which can eventually lead to cirrhosis. Chronic inflammation can also impair the liver's ability to perform its vital functions, including detoxification and protein synthesis, potentially leading to complications like portal hypertension and ascites if the underlying cause is not identified and managed promptly.
Here are some general areas an elevated Aspartate Aminotransferase (AST) 167 U/L level might lead a healthcare provider to consider:

Aspartate Aminotransferase (AST) is an enzyme, which is a type of protein that helps speed up chemical reactions within your body's cells. It plays a role in amino acid metabolism, a fundamental process for energy production and building blocks of life.
AST is found in many different tissues, but it is especially abundant in the liver, heart, skeletal muscles, and red blood cells. When cells in these tissues are damaged or inflamed, they can release AST into the bloodstream, which is why an elevated Aspartate Aminotransferase (AST) 167 U/L level can act as a signal.
It indicates that there might be some level of cellular distress or turnover occurring in one or more of these areas. This isn't a diagnosis in itself, but rather an indicator that prompts further investigation.
Your healthcare provider will often look at other related enzymes, like Alanine Aminotransferase (ALT), along with your medical history and other symptoms, to get a clearer picture of what the Aspartate Aminotransferase (AST) 167 U/L might mean specifically for you.
Understanding this context transforms a number into a valuable piece of information about your unique physiology.
An AST level around 167 U/L is most commonly attributable to acute viral hepatitis (like Hepatitis A, B, or C), or a significant bout of non-alcoholic steatohepatitis (NASH) driven by factors like obesity or insulin resistance.
Certain medications, particularly statins, acetaminophen in high doses, or some antibiotics, can also cause this degree of elevation by directly inducing liver cell stress or injury. Less frequently, but importantly, consider acute alcohol-induced liver damage, especially if there's a history of recent heavy consumption, or even early stages of autoimmune hepatitis.
Making thoughtful lifestyle choices can significantly support your overall health and organ function, and these choices might indirectly play a role in maintaining balanced enzyme levels, including Aspartate Aminotransferase (AST) 167 U/L.
Focusing on general well-being through daily habits can create a foundation for a healthier body. Regular physical activity, for instance, can enhance blood circulation and reduce inflammation throughout the body.
However, it's worth noting that very intense or prolonged exercise can temporarily elevate AST due to normal muscle breakdown. Therefore, engaging in moderate, consistent physical activity that feels good for your body is often encouraged.
Managing stress effectively is another vital component of a healthy lifestyle. Chronic stress can impact various bodily systems, and finding healthy outlets such as meditation, deep breathing, or spending time in nature can be incredibly beneficial.
Prioritizing adequate, restorative sleep, typically 7-9 hours per night for adults, allows your body to repair and regenerate, supporting organ health. Furthermore, avoiding harmful substances like excessive alcohol and tobacco use is crucial, as these are well-known contributors to liver damage and other health issues.
Organizations like the National Institutes of Health (NIH) consistently highlight the broad benefits of these healthy practices for a robust and resilient body. These integrated approaches foster an environment where your body can function more optimally, contributing to your overall vitality.
Your AST level of 167 U/L warrants immediate medical attention to identify the underlying cause. Schedule a follow-up appointment with your primary care physician for further evaluation, which should include viral hepatitis serologies (Hepatitis A, B, C), autoimmune markers (ANA, ASMA), and a lipid panel.
Discuss all current medications, supplements, and recent alcohol intake. Lifestyle modifications, such as eliminating or strictly limiting alcohol and adopting a balanced, low-fat diet, are crucial. Depending on initial findings, your doctor may refer you to a gastroenterologist or hepatologist for specialized testing, possibly including an abdominal ultrasound or transient elastography.
