The SGPT test (serum glutamic pyruvic transaminase), also called the ALT test, measures an enzyme found mainly in liver cells. When liver cells are inflamed or damaged, ALT leaks into the blood and the SGPT level rises. The normal range is roughly 7–40 U/L on most Pakistani lab reports, although many liver specialists consider values above about 30–33 U/L in men and 19–25 U/L in women worth attention. A high SGPT is a signal to find the cause, most often fatty liver, hepatitis B or C, alcohol or medicines.
Key points
- SGPT = ALT; SGOT = AST. Both are liver enzymes, but SGPT is more specific to the liver.
- Mildly raised SGPT (up to about 2–3 times normal) is most often due to fatty liver in Pakistan.
- Very high SGPT (in the hundreds or thousands) suggests acute hepatitis, medicine injury or a blocked blood supply and needs urgent care.
- A normal SGPT does not always mean a healthy liver; cirrhosis can have normal enzymes.

What Does the SGPT Test Mean?
SGPT is part of the liver function test (LFT). Doctors order it when screening for liver disease, when someone has symptoms such as tiredness, jaundice or upper right abdominal pain, before and during certain medicines (TB treatment, anti-epileptics, statins), and to monitor hepatitis or fatty liver. In Urdu it is often simply called jigar ka test or jigar ke enzyme ka test.
SGPT Normal Range
| Group | Typical lab reference | Healthier upper limit used by many hepatologists |
|---|---|---|
| Adult men | 7–40 U/L (lab dependent) | About 30–33 U/L |
| Adult women | 7–35 U/L (lab dependent) | About 19–25 U/L |
| Children | Varies with age | Use the lab’s paediatric range |
Always compare your result with the reference range printed on your report, because labs use different methods.
What Does High SGPT Mean?
A high SGPT means liver cells are under stress or being injured. It does not tell you the cause or how much scarring there is. Your doctor interprets it together with SGOT, bilirubin, alkaline phosphatase, albumin, platelet count, an ultrasound and your history.
How High Is Too High? SGPT Levels Explained
| SGPT level | What it often suggests | Action |
|---|---|---|
| Up to ~2× upper limit (e.g. 40–80) | Fatty liver, alcohol, medicines, early hepatitis B/C | See a doctor within weeks; ultrasound and viral tests |
| 2–5× (e.g. 80–200) | Chronic hepatitis, fatty liver with inflammation, medicine injury | Specialist review soon |
| 5–15× (200–600) | Acute hepatitis, autoimmune hepatitis, bile duct stone | Prompt specialist care |
| More than 15× (above 600–1000) | Acute viral hepatitis, drug toxicity (e.g. paracetamol overdose), reduced blood flow to the liver | Urgent; may need hospital |
So an SGPT of 70 is mildly raised and common with fatty liver, but it still deserves a check-up to find the reason. The “danger” lies less in the number than in the cause and whether symptoms like jaundice or confusion are present.
SGPT vs SGOT
SGOT (AST) is found in the liver but also in muscle, heart and red blood cells. The ratio of the two helps the doctor:
- SGPT higher than SGOT: typical of fatty liver and viral hepatitis.
- SGOT about twice SGPT: suggests alcohol-related liver disease or advanced scarring.
- Isolated high SGOT: may come from muscle injury or heavy exercise.
Common Causes of High SGPT in Pakistan
- Fatty liver disease: the most common cause today. See fatty liver meaning in Urdu.
- Hepatitis B and C: still very common and often silent. See hepatitis in Urdu.
- Hepatitis A and E: acute rises with jaundice, common in summer and the monsoon.
- Medicines and herbal products: TB drugs, some antibiotics, anti-epileptics, high-dose paracetamol, steroids for bodybuilding and unregulated herbal powders.
- Alcohol.
- Autoimmune hepatitis, celiac disease, thyroid disease and Wilson’s disease (in young patients).
- Heavy exercise or muscle injury shortly before the test.
Preparing for the Test
SGPT alone does not usually require fasting, but if your doctor has also ordered sugar or cholesterol tests, fast for 8–12 hours. Avoid heavy exercise and alcohol for 24–48 hours before, and tell the doctor about all medicines and supplements.
How to Lower SGPT
The real goal is to treat the cause, not just the number:
- Fatty liver: lose 7–10% of body weight, cut sugary drinks, sweets and fried food, walk 30 minutes a day. Our fatty liver diet chart helps.
- Hepatitis B or C: antiviral treatment brings SGPT down as the virus is controlled or cured.
- Medicines: stop or change the offending drug only with your doctor’s advice.
- Alcohol: stop completely.
- Coffee (2–3 cups a day without sugar) is associated with better liver health in studies.
There is no single fruit or “liver detox” that lowers SGPT. Be cautious with herbal liver tonics; some can themselves raise liver enzymes.
When to See a Liver Specialist
- SGPT above normal on two tests a few weeks apart
- SGPT more than 3 times the upper limit
- Any raised SGPT with jaundice, dark urine, abdominal swelling or confusion
- Positive hepatitis B or C test
- Raised SGPT with diabetes or obesity (to check for scarring)

Urdu Mein Khulasa
ایس جی پی ٹی جگر کا ایک انزائم ہے۔ جب جگر کے خلیے متاثر ہوتے ہیں تو یہ خون میں بڑھ جاتا ہے۔ عام طور پر اس کی نارمل حد تقریباً سات سے چالیس یونٹ ہوتی ہے۔ پاکستان میں ایس جی پی ٹی بڑھنے کی سب سے عام وجوہات فیٹی لیور، ہیپاٹائٹس بی اور سی، کچھ دوائیں اور دیسی نسخے ہیں۔ صرف نمبر کم کرنے کے بجائے اصل وجہ کا علاج ضروری ہے، اس لیے بڑھا ہوا ٹیسٹ آنے پر جگر کے ماہر ڈاکٹر سے رجوع کریں۔
Frequently Asked Questions
What is the normal SGPT level?
Most labs report a normal SGPT of about 7–40 U/L. Many liver specialists consider values above roughly 30–33 U/L in men and 19–25 U/L in women as possibly abnormal.
Is an SGPT of 70 high?
Yes, it is mildly raised (under twice the usual limit). It is often due to fatty liver but should be evaluated with an ultrasound and hepatitis tests.
What happens if SGPT is high?
High SGPT itself causes no symptoms. It indicates liver cell injury, and if the cause is not treated, ongoing injury can lead to scarring over time.
Which fruit reduces SGPT?
No single fruit lowers SGPT. A diet rich in vegetables, fruit and whole grains, with weight loss and less sugar, improves fatty liver and lowers SGPT over weeks to months.
Is fasting required for the SGPT test?
Not usually for SGPT alone. Fast only if other tests such as glucose or lipids are being done at the same time.
What is the danger level of SGPT and SGOT?
Levels above about 10–15 times normal (several hundred to thousands) or any rise with jaundice, confusion or bleeding need urgent medical care.
Conclusion
The SGPT test is a simple, valuable window into liver health. A mildly high result is common and usually treatable, but it should never be ignored, because it may be the first sign of fatty liver or silent hepatitis. If your SGPT is raised, consult Dr. Omer Hassaan Aftab Ahmad in Islamabad on 0336 5993116.
