About this service

Alanine aminotransferase (ALT) analysis is a laboratory test that measures the level of the alanine aminotransferase enzyme in the blood, which is considered an important indicator of liver health. This enzyme is produced mainly in the liver, and elevated levels may indicate liver cell damage or inflammation, such as viral hepatitis, alcohol-related effects, or the impact of certain medications. This test is usually performed as part of routine examinations to assess liver function and may be requested when symptoms such as fatigue, jaundice, or abdominal pain appear. Blood sampling is typically preferred in the morning after an 8-hour fast to ensure accurate results. ALT analysis is an effective tool for monitoring liver health and ensuring the absence of more serious medical problems.

Purpose Test

Hepatitis: Elevated ALT levels often indicate viral hepatitis, such as hepatitis A, B, or C, or hepatitis caused by other factors.
Liver Cell Damage: Conditions like cirrhosis, fatty liver (alcoholic or non-alcoholic) can increase ALT levels, indicating liver cell damage.
Chronic Liver Diseases: Chronic hepatitis or cirrhosis may show elevated ALT levels.
Toxic Effects: Certain medications, drugs, or toxins can harm the liver and raise ALT levels.
Other Health Issues: Elevated ALT levels may also suggest health problems unrelated to the liver, such as heart disease or skeletal muscle disorders.

Recommended groups

Individuals with liver symptoms: Such as jaundice (yellowing of the skin and eyes), abdominal pain, or unexplained fatigue.
People with a family history of liver disease: If there is a family history of liver inflammation or fibrosis, regular testing may be recommended.
Individuals taking medications that may affect the liver: Such as certain nonsteroidal anti-inflammatory drugs (NSAIDs), antibiotics, sedatives, and others.
People with chronic conditions: Such as diabetes, high blood pressure, or obesity, as they are more susceptible to liver problems.
Alcohol consumers: Testing is advised for those who consume large amounts of alcohol to assess its impact on the liver.
Individuals with viral hepatitis: Such as hepatitis B or C, to monitor liver health.
Routine monitoring: It is recommended as part of routine medical check-ups for people over 40 years old, or those with risk factors for liver disease.

Symptoms indicative

Jaundice: Yellowing of the skin and eyes, indicating elevated bilirubin levels in the blood.
Abdominal Pain: Especially in the upper right area of the abdomen, where the liver is located.
Unexplained Fatigue: Persistent feeling of tiredness or weakness.
Loss of Appetite: Reduced desire to eat, which may lead to weight loss.
Nausea and Vomiting: Feeling dizzy or the urge to vomit.
Dark Urine: Change in urine color to a darker shade.
Pale Stools: Appearance of light-colored or grayish stools.
Itchy Skin: Generalized itching sensation on the skin.
Sleep Pattern Changes: Difficulty sleeping or sleep disturbances.
Concentration Problems: Feeling unable to focus or pay attention.

Normal Levels

For Males: From 10 to 40 units per liter (U/L).
For Females: From 7 to 35 units per liter (U/L).
Variation in Values: Normal values may vary based on factors such as age, weight, overall health, and laboratory standards.
Elevated Levels: If ALT levels are higher than normal, it may indicate liver damage, inflammation, or other health conditions.
Correct Interpretation: Results should always be interpreted by a specialist doctor, as elevated levels may require further evaluation and additional tests.
