SGPT Test: Meaning, Full Form, Normal Range, and Why It’s Important for Liver Health

You’re at a party, enjoying a drink and laughter, and suddenly a science freak says, “You know, the liver has the ability to regenerate itself in response to injury.” Well, your friend isn’t wrong, but that doesn’t mean you can keep stressing your liver with unhealthy habits of drinks and junk food, thinking it’ll magically fix itself.

Your liver is like a powerhouse; it handles over 500 tasks a day. From digesting food, storing energy, making proteins, and cleaning toxins from your blood. It quietly keeps you alive and active.

Now imagine this: if your liver begins to fail due to poor habits, all these vital functions will suffer. That’s why it’s crucial to monitor your liver’s health — and one simple way to do that is through a blood test called the SGPT test.

What is the SGPT Test?

The SGPT test, also known as the ALT (Alanine Aminotransferase) test, is a liver function test that measures the level of an enzyme called alanine aminotransferase in your blood.
ALT primarily exists inside liver cells and helps catalyze important metabolic processes.

When liver cells are damaged due to infection, fatty liver disease, alcohol use, or certain medications, ALT leaks into the bloodstream.
High levels of ALT in the blood can indicate liver cell injury. Doctors use this test to evaluate liver health, detect diseases such as hepatitis, and monitor treatment effectiveness.

In short, the SGPT test is like a report card for your liver’s health — simple, accurate, and extremely important.
 

Is SGPT the Same as ALT?

Yes. SGPT and ALT are two names for the same enzyme.

How the SGPT Test Works

ALT/SGPT is stored inside liver cells for cellular function and energy production.

When liver cells are damaged, the enzyme leaks into the bloodstream.

The SGPT test measures this enzyme level — elevated results signal liver stress or injury, helping doctors diagnose conditions like hepatitis or fatty liver.

SGPT Test: Means This

ALT/SGPT inside liver cells (for cellular function & energy production) → Liver cell damage occurs → ALT/SGPT leaks into bloodstream → SGPT Test measures their level  → Elevated levels signal liver cell damage →  Doctors detect hepatitis or other liver conditions

• Normal ALT/SGPT levels indicate normal liver function. 
• Abnormal ALT/SGPT levels indicate liver stress or injury needing further evaluation.

SGPT Test Full Form

It stands for Serum Glutamic Pyruvic Transaminase, widely known as the ALT (Alanine Aminotransferase) test.

Common Names for the SGPT Test

Here are a few common names for the SGPT test:

• Alanine transaminase (ALT)
• Alanine aminotransferase
• Serum glutamic-pyruvic transaminase (SGPT)
• GPT test
• Liver enzyme test
• Liver function or health check-up

What is the Need for the SGPT Test | The Benefits

Do you want to know how well your liver is functioning? Then your doctor may order a blood panel test that includes an ALT or SGPT test, following the 3 major benefits.

1. Liver Health Screening

The ALT or SGPT test detects early liver issues before symptoms appear. It catches health risks  associated with:

• Heavy alcohol use
• Diabetes
• Obesity
• Family history of liver disease

ALT tests are often included in routine blood panel tests (comprehensive metabolic panel (CMP) to evaluate your general overall health.

2. Liver Health Monitoring

Tracks liver health over time if you have existing liver conditions or are taking medicines that may damage the liver.

3. Liver Health Diagnosing

Assists doctors in investigating symptoms such as nausea, jaundice, fatigue, or abdominal pain by checking for liver injury or disease.

If you are experiencing the following signs and symptoms of liver conditions, then your doctor can order the ALT or SGPT test for proper diagnosis. 

• Nausea
• Vomiting
• Belly (abdominal) pain
• Jaundice 
• Tiredness (fatigue)
• Loss of appetite
• Itchy skin

Note: The doctor can’t diagnose a condition based solely on ALT levels; it is part of a comprehensive diagnostic panel.

SGPT Normal Range

Knowing your SGPT normal range means you are taking a step toward caring for your liver health. This will help you to take the necessary action:

A. Normal Range for Male

ALT levels are typically higher in males.

SGPT (ALT) Level (U/L)	Results Interpretation
Less than 10	Generally not a concern; may indicate vitamin B6 deficiency, chronic kidney disease or nutritional issues if symptomatic
10 – 40	Healthy range for male
41 – 100	Mild liver stress or early liver issues
Greater than 100	Potential liver damage or liver disease

B. Normal Range for Females

SGPT (ALT) Level (U/L)	Results Interpretation
Less than 7	Generally not a concern; may indicate vitamin B6 deficiency, chronic kidney disease or nutritional issues if symptomatic
7 – 35	Healthy range for females
36 – 100	Possible mild liver stress or early liver issues
Greater than 100	Possible liver damage or liver disease

C. Normal Range for Children

SGPT (ALT) Level (U/L)	Results Interpretation
Less than 7	Generally not a concern
7 – 56	Normal range for children
57 – 100	Could suggest mild liver stress or early liver disease
Greater than 100	Possible significant liver injury or disease

Note: It’s important to know that having a high ALT/SGPT test result doesn't always mean you have a medical condition. Hence, do not interpret the result on your own. Always take professional guidance.

What Disease Does SGPT Indicate?

The liver health checkup can help detect the following conditions:

• Non-Alcoholic Fatty Liver Disease (NAFLD)

Alcoholic Liver Disease

• Hepatitis (Inflammation of the liver)
• Cirrhosis (Progressive scarring of the liver)
• Liver ischemia

Less than 5% of people with elevated ALT or SGPT levels have severe liver conditions.

What Does It Mean if  it is High?

The main aim of the ALT blood test is to assess liver health. If cells in your liver are damaged, it can cause ALT to leak into the bloodstream, so an ALT blood test can help catch early liver issues, such as:

• Alcohol-induced liver injury
• Fatty liver disease/ fat deposit in your liver
• Liver ischemia (death of liver tissue due to inadequate blood flow to the liver)
• Hemochromatosis (excessive  iron in your body)
• Mononucleosis ("mono") is, contagious viral infection.
• Certain genetic conditions affecting the liver
• Hepatitis (liver inflammation)
• Cirrhosis (scarring of the liver)
• Taking medications that are not good for your liver
• Liver tumor or liver cancer

What Affects SGPT Levels?

There are many reasons why the SGPT levels can be elevated. Some of the seasons are as follows:

1. Excessive Alcohol Consumption

It damages liver cells, raising SGPT levels in the bloodstream.

2. Liver Diseases

Conditions such as hepatitis, fatty liver, or cirrhosis cause enzyme release due to liver cell injury.

3. Medications & Other Toxins

 Paracetamol, certain antibiotics, and toxins can harm the liver cells.

4. Obesity and Diabetes

Obesity and diabetes are metabolic disorders that lead to the accumulation of fat and inflammation in the liver.

5. Intense Exercise

Intense exercise can temporarily increase SGPT because of muscle strain and liver stress.

SGPT Test Cost

The price of the SGPT test can vary based on the laboratory or hospital you choose and the city you live in.

The typical SGPT Test Cost ranges between ₹169 and ₹399. The price can go up to ₹1000 as well.

For Example:

• ₹238 in Bangalore
• ₹250 in Delhi and Gurgaon
• ₹300 in Hyderabad

The prices can also vary depending on discounts or packages offered by the labs.

SGPT Test Cost Depends On

What Are The Risks?

A liver enzyme test is generally safe and comes with no risk; however, in rare cases, it can cause the following at the site of injection:

• Slight pain or bruising
• Rare chance of infection
• Minor bleeding or hematoma (a solid swelling of clotted blood) under the skin
• Faint after the blood draw

How to Prepare for an SGPT Test?

There is no special preparation; just follow a few simple steps:

• Do not drink alcohol for at least 24 hours before the test to ensure no elevation of the enzyme.
• Fasting is not usually required.
• Stay relaxed and hydrated before the blood sample is taken. This will help to achieve accurate results.
• Inform your doctor about any medications or supplements that may interfere with the results.

When Is The SGPT Test Recommended?

Your doctor may recommend this liver enzyme test in the following situations:

• During routine health checkups.
• Monitor risk factors such as heavy alcohol use, obesity, or family history of liver disease.
• To know the reason behind jaundice, abdominal pain, fatigue, itching, nausea, and vomiting.
• To monitor existing liver conditions such as hepatitis, fatty liver disease (alcoholic and non-alcoholic), cirrhosis, or liver damage.
• To check the liver’s response to medications that may affect liver function.
• For early detection of liver damage due to existing health conditions like diabetes, heart failure, or hepatitis.
