The SGPT test, also known as the ALT (Alanine Aminotransferase) test, is a critical blood test used to measure the level of the SGPT enzyme in the liver. This enzyme is essential for liver function and often serves as an indicator of liver health. This comprehensive guide will delve into the SGPT test, covering its normal range, cost, causes of elevated SGPT levels, symptoms related to high SGPT, and the significance of this test in diagnosing liver conditions.

Understanding the SGPT Test

The SGPT test measures the amount of SGPT enzyme in your blood. SGPT, or Serum Glutamic Pyruvic Transaminase, is another name for the ALT enzyme. This enzyme is primarily located in the liver but is also present in smaller amounts in the kidneys, heart, and muscles. The SGPT test is crucial for evaluating liver function and identifying liver damage.

The Importance of the SGPT Test

The liver plays a vital role in the body, responsible for detoxification, protein synthesis, and producing biochemicals necessary for digestion. When the liver is damaged, it releases SGPT into the bloodstream, increasing the enzyme’s levels. Monitoring SGPT levels through the SGPT test is essential for diagnosing liver diseases like hepatitis, fatty liver disease, cirrhosis, and liver cancer.

Normal SGPT Levels

Knowing the normal range for SGPT levels is key to understanding your test results. The normal range can slightly vary depending on the lab and the testing method used. Typically, the normal range for SGPT levels is:

Men: 7 to 56 units per liter (U/L)
Women: 7 to 45 units per liter (U/L)

It's important to consider that SGPT levels can be influenced by factors like age, gender, and overall health. Thus, a healthcare provider should always interpret the results in the context of the patient’s medical history and other diagnostic tests.

Causes of Elevated SGPT Levels

Several conditions and factors can cause elevated SGPT levels. Common causes include:

  • Hepatitis: Viral infections like hepatitis A, B, and C cause inflammation and liver cell damage, leading to elevated SGPT levels.
  • Alcohol Consumption: Excessive alcohol intake damages liver cells, resulting in higher SGPT levels.
  • Fatty Liver Disease: Both alcoholic and non-alcoholic fatty liver disease can increase SGPT levels.
  • Medications: Certain medications like statins, antibiotics, and pain relievers can cause liver damage and raise SGPT levels.
  • Liver Cirrhosis: Chronic liver damage can lead to cirrhosis, elevating SGPT levels.
  • Autoimmune Hepatitis: An autoimmune disorder where the body's immune system attacks liver cells.
  • Heart Failure: Conditions like heart failure can cause liver congestion, leading to elevated SGPT levels.
  • Muscle Damage: Since SGPT is also found in muscles, extensive muscle damage can elevate levels.
  • Obesity: Being overweight or obese is associated with fatty liver disease and higher SGPT levels.

Symptoms of High SGPT Levels

High SGPT levels can indicate liver damage, presenting various symptoms. It's crucial to recognize these symptoms and seek medical advice if you experience any of them:

  • Jaundice: Yellowing of the skin and eyes, indicating high bilirubin levels.
  • Fatigue: Persistent tiredness or weakness.
  • Abdominal Pain: Pain or discomfort in the upper right side of the abdomen.
  • Swelling: Swelling in the legs and ankles, also known as edema.
  • Dark Urine: Dark-colored urine can be a sign of liver dysfunction.
  • Diminished Appetite: A reduced urge to eat, frequently leading to weight reduction.
  • Nausea and Vomiting: Feeling sick to the stomach and vomiting.
  • Itchy Skin: Itching can be a result of bile salt accumulation under the skin.
  • Confusion: In severe cases, liver dysfunction can lead to confusion and cognitive impairment.

Diagnosing Liver Conditions with the SGPT Test

The SGPT test is a valuable tool for diagnosing various liver conditions. When combined with other tests and clinical evaluations, it provides a comprehensive picture of liver health. Some conditions that can be diagnosed using the SGPT test include:

  • Acute and Chronic Hepatitis: By measuring SGPT levels, doctors can assess the severity of liver inflammation and monitor treatment effectiveness.
  • Fatty Liver Disease: Elevated SGPT levels can indicate fatty liver disease, requiring lifestyle changes and medical management.
  • Cirrhosis: Regular monitoring of SGPT levels helps manage cirrhosis and prevent complications.
  • Liver Cancer: High SGPT levels can be a marker for liver cancer, prompting further diagnostic tests like imaging and biopsies.
  • Drug-Induced Liver Injury: The SGPT test helps detect liver damage caused by medications and guide adjustments in drug therapy.

The SGPT Test Procedure

The SGPT test is a straightforward procedure involving drawing a small blood sample from a vein, usually in the arm. Here's what to expect during the test:

  • Preparation: No special preparation is needed for the SGPT test, but your doctor may advise avoiding certain medications or supplements before the test.
  • Blood Draw: A healthcare professional will clean the area on your arm with an antiseptic and insert a needle to draw blood. The process is quick and may cause minimal discomfort.
  • Sample Analysis: The blood sample is sent to a laboratory where it is analyzed for SGPT levels.
  • Results: Your doctor will receive the results and discuss them with you, explaining what they mean in the context of your overall health.

Factors Influencing SGPT Test Results

Several factors can affect SGPT test results, and it's important to consider these when interpreting the results:

  • Medications: Certain drugs can either increase or decrease SGPT levels. Make sure to provide your doctor with a complete list of all the medications you are currently using.
  • Diet and Lifestyle: Alcohol consumption, smoking, and diet can affect liver function and SGPT levels.
  • Exercise: Intense physical activity can temporarily raise SGPT levels due to muscle damage.
  • Medical Conditions: Other health conditions, such as thyroid disorders, can impact SGPT levels.
    Lowering Elevated SGPT Levels

If you have elevated SGPT levels, addressing the underlying cause is essential to lower them. Check Some Steps:

  • Avoid Alcohol: Limiting or abstaining from alcohol can significantly reduce liver damage and lower SGPT levels.
  • Healthy Diet: Eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins supports liver health.
  1. Engaging in regular exercise: Consistent physical activity aids in sustaining a healthy weight and lowers the likelihood of developing fatty liver disease.
  2. Medications: Follow your doctor's advice regarding medications that may affect liver health.
  3. Weight Management: Achieving and maintaining a healthy weight can lower SGPT levels and improve liver function.
  4. Avoid Toxins: Minimize exposure to environmental toxins and chemicals that can harm the liver.
  5. Regular Monitoring: Regular check-ups and SGPT tests can help monitor liver health and catch issues early.


Cost of the SGPT Test

The cost of an SGPT test can vary depending on the laboratory, location, and whether it is part of a comprehensive liver function panel. On average, the price of an SGPT test ranges from 150rs to 400rs. Some health insurance plans may cover the cost of the test, especially if it is deemed medically necessary. It is advisable to check with your insurance provider and the testing facility for specific pricing details.



The SGPT test is an essential diagnostic tool for assessing liver health and detecting liver damage. Understanding the normal range, causes of elevated levels, symptoms, and the importance of the SGPT test can help you take proactive steps to maintain liver health. If you experience symptoms associated with liver dysfunction or have risk factors for liver disease, consult your healthcare provider about getting an SGPT test. Regular monitoring, a healthy lifestyle, and prompt medical attention are key to managing liver conditions and ensuring overall well-being.
