Blood Work or Blood Tests can be quite daunting. That is because the blood tests tend to be confusing. Imagine a situation where you are ordered a blood test that reads “SGPT test”. We are sure that you have every reason to feel annoyed. Just because you don’t know what it means or why it has been ordered, you have every reason to feel anxious. 

You are not the only one – the term leaves several of us feeling anxious, because the acronym is quite complicated and much less heard about. 

If your doctor has ordered an SGPT test for you and you are looking to find what it is, this guide is just for you. 

What is SGPT?

SGPT means Serum Glutamic Pyruvic Transaminase. So, an SGPT blood test is designed to help doctors find what is inside your liver. The test is also referred to as ALT (Alanine Aminotransferase) on your report—they are the exact same thing.

SGPT is an element or component that always stays inside your liver cells. It is responsible for breaking down amino acids  into energy. Under ideal conditions, the component stays inside the liver. However, when your liver malfunctions or has any issues, SGPT escapes into your bloodstream. 

That is when your bloodstream contains a high amount of SGPT. Such an occurrence will make you understand that your liver is under stress. 

Why is the SGPT Test Important?

You can consider an SGPT test to be an early warning system. It may be noticed that the liver is really tough and does not give out any symptoms until it is severely damaged or under heavy stress. Thus, an SGPT test can help reveal early if your liver has any severity or health conditions. 

An SGPT blood test becomes crucial in the following areas –

  • Early detection – The test can identify the symptoms of fatty liver and hepatitis quite early. 
  • Monitoring treatment – It can also help find out if your liver is working as expected. 
  • Routine health check-up – It can help doctors understand if your liver is handling your lifestyle properly. It helps analyse the impact of diet, alcohol, and medications on your liver. 

What are the uses of the SGPT Test?

Doctors may recommend the SGPT tests for several reasons. In fact, there is no reason to be worried just because an SGPT test has been ordered.

A few reasons that your doctor may have ordered an SGPT test include 

  • Diagnosis of liver diseases – The test is useful in diagnosing viral hepatitis, cirrhosis, or liver damage caused by alcohol. 
  • Monitoring the medication – Some medications may stress your liver. These include medicines like statins and strong antibiotics. SGPT test helps the doctors to decide if the dosage needs to be altered. 
  • General screening – It is a part of a routine screening or health check-up. It can also be a part of a complete metabolic panel. 
  • Tracking of symptoms – In case you have disease, the test can help understand if the disease originates from the liver. These diseases or symptoms include jaundice, dark urine, or upper abdominal pain

These are just a few reasons doctors may order SGPT test. Doctors may order it for a wide range of other reasons as well. 

How to understand the test results of the SGPT test?

Interpreting the SGPT test and its results can depend on multiple factors. Just because you got a single high number does not mean you have a problem. 

The "De Ritis Ratio" (Advanced Interpretation)

Doctors may choose to find the ratio between ALT and AST (also known as SGOT and SGPT respectively) to understand the severity of the ailment. This ratio is known as De Ritis Ratio. 

  • AST/ALT Ratio > 2:1: It indicates Alcoholic Liver Disease. Alcohol damages the mitochondria of cells where AST is found, causing it to spike disproportionately.
  • AST/ALT Ratio < 1: This is more common in Non-Alcoholic Fatty Liver Disease (NAFLD) and viral hepatitis. In these cases, ALT (SGPT) is usually higher than AST.
  • AST/ALT Ratio > 1 in NAFLD: If someone has fatty liver but their ratio flips (AST becomes higher), it can sometimes indicate that the disease has progressed to fibrosis or cirrhosis.

The severity levels 

  • Mid elevation – If you find the elevation is two to three times higher than normal, it is seen as an indicator of fatty liver. This can be one of the most common abnormal results. It can also indicate medication usage and chronic viral hepatitis. 
  • Moderate elevation – This can happen when the elevation is 10 to 20 times than normal. It can be indicative of alcoholic hepatitis or acute viral hepatitis.
  • Severe elevation – The elevation can be 50 times more than the normal level. It will indicate massive, sudden liver injury, such as a paracetamol overdose or acute liver failure or some metabolic illness(Acute Wilsons or acute autoimmune disorder)or ischemic hepatitis 

What is the Normal Range of SGPT/ALT?

In medicine, a term like SGPT normal range is never used. This is because the test results typically are dependent on the equipment used. However, we can consider the following acceptable levels. 

General Reference Ranges

  • Adult Males: 10 to 40 U/L (Units per Liter)
  • Adult Females: 7 to 35 U/L

Note – It may be noted that some labs may consider a higher cut off such as 55 to 60 U/L. However, many hepatologists argue that the normal values should be below 30 for men and below 19 for women. 

SGPT Normal Range in Children

In the case of children, the right levels would be a little different. 

  • Infants: Can be up to 50 U/L.
  • Children: Similar to adults, typically < 40 U/L.

SGPT Normal Range in Pregnancy

The pregnancy changes bodily chemistry significantly. It may be noted that the SGPT levels drop significantly during a healthy pregnancy. 

  • 1st Trimester: 3 – 30 U/L
  • 2nd Trimester: 2 – 33 U/L
  • 3rd Trimester: 2 – 25 U/L

Note – If the SGPT levels for pregnant women is above 50, it could be a red flag. While it is a normal value for a woman who is not pregnant based on the lab, it is definitely a high level for a pregnant woman.

SGPT Levels Chart

If you want a glance at the levels of SGPT, here is the chart that should help you –

Category

Range (approx. U/L)

How To Control SGPT? (Diet & Lifestyle)?

If the SGPT levels have gone up, because of lifestyle related factors, we have a good news for you. Liver is the only organ in the body that can regenerate itself. If you follow a few methods religiously, you should be able to lower your SGPT levels in 4 to 4 weeks. 

The liver diet

There are a few diets that are friendly to the liver and a few others that are harmful to the liver. 

It is important to change your diet so that your liver can benefit the most. 

  • Coffee – You heard that right. Drinking black coffee two to three times a day can help reduce the liver enzymes. It reduces the risk of fibrosis. 
  • Cruciferous vegetables – These vegetables produce detoxifying enzymes. A few vegetables we recommend include broccoli, Brussels sprouts, and cauliflower.
  • Omega 3 fatty acids – Eating fish like sardines and salmon can help reduce liver inflammation and fats in the liver. Even walnuts are found to be a good option in this context. 
  • Garlic – It is known to activate the liver enzymes that flush out toxins. 

It is advisable to avoid the white carbs such as sugar, white bread and pasta. They can spike insulin which stores sugar in the liver. 

Lifestyle modifications 

A few modifications to your lifestyle can have a lasting impact on the health of your liver. 

  • Stop alcohol completely – If you have high SGPT levels, even so called moderate drinking can be risky. Avoid alcohol completely. If not, take a break for at least 30 days. 
  • Gradual weight loss – Aim for a weight loss, but make it gradual. Rememeber that starvation diets such as keto can be counter productive. These diets stress the liver further. 
  • Exercise – Cardio and resistance training are a few good options to enhance liver health

Supplements 

If the above seem to insufficient, you can take supplements that help your liver get back to proper health. 

  • Vitamin E – It is generally prescribed for non diabetic patients who have fatty liver. 

Note – Do not start supplements on your own. Consult your doctor for recommendations. 

Symptoms of High SGPT Levels

There are no clear symptoms of high SGPT levels. 

However, a few indicators may include 

Mild to moderate elevation 

  • Zero symptoms
  • Mild fatigue or brain fog
  • Slight discomfort in the upper right abdomen

Severe elevation 

  • Dark urine 
  • Pale stools
  • Nausea and vomiting 
  • Itchy skin 

What Affects SGPT Levels? (Causes of Increase)

There may be multiple reasons for the elevated levels of SGPT. Liver is a very sensitive organ and many factors can irritate it. 

Liver related issues 

Some liver conditions can increase SGPT levels. 

  • Fatty liver 
  • Excessive alcohol consumption 
  • Hepatitis
  • Hemochromatosis 
  • Wilson s disease
  • Autoimmune hepatitis 
  • Drugs – compliementary medications 

Non-liver causes 

  • Muscle damage due to injury or heavy workouts 
  • Celiac disease
  • Thyroid disorders 

Medications and supplements

  • Excessive use of pain relievers 
  • Cholesterol medications 
  • Herbal supplements like Kava, Comfrey, and even Green Tea Extract

How to Prepare for an SGPT Test?

If you want most accurate results of your SGPT test, we recommend following a few preparatory steps. 

Fasting 

If the test involves SGPT alone, there is no need for fasting. However, if it forms part of a panel, we recommend fasting for 10 to 12 hours prior to the test. 

Other preparatory steps include 

  • Avoid alcohol completely 24 hours before the test. 
  • Avoid strenuous physical activities 

Inform the doctor about any medications you are on. Do not stop the prescription medications unless you are asked to. 

What Happens During the Test?

The test follows a simple procedure. There is absolutely no need to be anxious. 

  • A technician ties a tourniquet around your upper arm to make veins swell with blood.
  • The site (usually inside the elbow) is wiped with an alcohol swab.
  • A thin needle is inserted. You’ll feel a quick "ant bite" pinch. It takes less than 60 seconds to fill the vial.
  • A cotton ball and bandage are applied. You can drive and eat immediately afterward.

That does it. It will take around 24 hours to get the report. 

When is the SGPT Test Recommended?

Doctors typically order a SGPT test in the following scenarios –

  • If you belong to the risk category. Some of these may include heavy alcohol consumption, overweight and diabetes. 
  • If you have a family history of liver issues 
  • If you have a heavy exposure to tattoos, body piercings, or have had a blood transfusion
  • If you have symptoms like chronic fatigue, unexplained nausea, or abdominal pain.
  • If you have been taking medicines like statins and antibiotics

Tips to Maintain Healthy SGPT Levels

If you want to be safer from high SGPT levels, there are a few precautions that you should follow. 

  • Practice Safe Sex: Hepatitis B and C can be sexually transmitted.
  • Vaccinate: Vaccines are available for Hepatitis A and B. They are highly effective.
  • Don't Share Personal Items: Razors and toothbrushes can carry microscopic amounts of blood.
  • Wash Produce: Pesticides can stress the liver. Wash fruits and veggies thoroughly
  • Be Careful with Acetaminophen: Never take more than the recommended dose, and never mix it with alcohol.

Conclusion

So, if your doctor has ordered an SGPT test, there is nothing to worry about. The test acts as a window for your liver health. Of course, a high result can be alarming, but you can easily reduce it following the right practices. 

The liver is the most forgiving organ in the human body. It wants to heal. By understanding what SGPT means and responding to its warning signals early, you can ensure this vital chemical factory keeps running smoothly for the rest of your life.
