Liver Function Test (LFT) in Nepal: When You Need One and How to Prepare
A liver function test in Nepal is one of the most commonly ordered blood tests — and one of the most misunderstood. Your doctor may have recommended it after you mentioned fatigue, yellowing skin, or unexplained abdominal discomfort. Or maybe it showed up as part of a routine health package, and now you’re staring at terms like SGPT, SGOT, and bilirubin with no idea what they mean.
The liver is one of the hardest-working organs in your body, filtering toxins, processing medications, and producing essential proteins — often without giving any warning signs until damage has already progressed. This is exactly why a liver function test matters: it can flag a problem long before you feel sick.
This guide explains what the test measures, who should get one, and how to prepare for accurate results.
What Is a Liver Function Test?
A Liver Function Test, commonly called LFT, is a panel of blood tests that measure enzymes, proteins, and other substances produced or processed by the liver. Abnormal levels can indicate inflammation, infection, fatty liver disease, or more serious liver damage.
Unlike some blood tests, an LFT typically does not require strict fasting, though your doctor or lab may still ask you to fast for 8–10 hours if the panel is combined with other tests like a lipid profile or blood sugar test.
What Does a Liver Function Test Measure?
A standard liver function test panel includes several key markers.
1. ALT (Alanine Aminotransferase) / SGPT
ALT is an enzyme found mainly in the liver. When liver cells are damaged or inflamed, ALT leaks into the bloodstream, making it one of the most sensitive markers for liver injury.
Normal range: 7–56 U/L
2. AST (Aspartate Aminotransferase) / SGOT
AST is found in the liver as well as the heart, muscles, and kidneys. It’s often evaluated alongside ALT — when both are elevated, the liver is the more likely source.
Normal range: 10–40 U/L
3. ALP (Alkaline Phosphatase)
ALP is an enzyme linked to the bile ducts. Elevated levels can point toward bile flow obstruction, liver disease, or in some cases, bone conditions.
Normal range: 44–147 U/L
4. Bilirubin (Total and Direct)
Bilirubin is a yellow pigment produced when red blood cells break down. The liver processes and removes it from the body. High bilirubin causes jaundice — the yellowing of skin and eyes that often prompts people to get tested in the first place.
Normal range: Total bilirubin 0.1–1.2 mg/dL
5. Albumin and Total Protein
Albumin is a protein made by the liver that helps maintain fluid balance and transport substances through the blood. Low albumin can indicate chronic liver disease or poor liver function.
Normal range: Albumin 3.5–5.0 g/dL
6. GGT (Gamma-Glutamyl Transferase)
GGT is especially sensitive to alcohol consumption and bile duct issues. It’s often used alongside ALP to help pinpoint whether a problem originates in the liver or bones.
Normal range: 8–61 U/L (varies between labs)
Who Should Get a Liver Function Test in Nepal?
Liver disease often develops silently, which makes screening important even without obvious symptoms. You should consider a liver function test in Nepal if you:
- Regularly consume alcohol
- Are overweight or have been told you may have fatty liver
- Have diabetes or high cholesterol
- Take medications known to affect the liver (including some long-term pain relievers)
- Have a family history of liver disease or Hepatitis B/C
- Notice symptoms like fatigue, loss of appetite, nausea, dark urine, or yellowing skin and eyes
- Are being monitored for an existing liver condition
Fatty liver disease in particular has become increasingly common in Nepal due to rising obesity rates and dietary shifts, according to the World Health Organization, making routine screening more relevant even for people without a diagnosed condition.
How to Prepare for a Liver Function Test
Proper preparation helps ensure your results accurately reflect your liver health.
- Inform your doctor about all medications and supplements you’re taking, as several can affect liver enzymes
- Avoid alcohol for at least 24 hours before the test
- Avoid strenuous exercise the day before, as intense activity can temporarily raise ALT and AST levels
- Fast for 8–10 hours if your doctor has combined the LFT with other tests
- Stay hydrated, as proper hydration supports easier blood draw and accurate results
What Happens If Your Results Are Abnormal?
A single abnormal result doesn’t necessarily mean serious liver disease — values can be temporarily affected by recent alcohol use, certain medications, or even strenuous exercise. However, persistently abnormal results should be taken seriously. Depending on the findings, your doctor may recommend:
- Repeat testing to confirm whether the abnormality persists
- Imaging tests such as a liver ultrasound to check for fatty liver or structural changes
- Lifestyle changes — reducing alcohol intake, improving diet, and increasing physical activity
- Further blood work to check for viral hepatitis or other underlying causes
- Medication review if a current drug may be contributing to elevated enzymes
Catching liver issues early, while they’re often reversible through lifestyle changes, is far easier than managing advanced liver damage later on.

Conclusion
A liver function test in Nepal is a simple, affordable way to catch liver problems before they become serious — often well before any symptoms appear. Understanding what ALT, AST, bilirubin, and the other markers actually mean gives you a real say in protecting one of your body’s most essential organs.
If you fall into a higher-risk group, or it’s simply been a while since your last check-up, there’s no better time to get tested.
FAQ Schema
What is a normal liver function test result?
Normal results generally fall within ALT 7–56 U/L, AST 10–40 U/L, total bilirubin 0.1–1.2 mg/dL, and albumin 3.5–5.0 g/dL, though exact ranges can vary slightly between labs.
Do I need to fast before a liver function test?
Not always. LFT alone usually doesn’t require fasting, but if it’s combined with tests like a lipid profile or fasting blood sugar, your doctor may ask you to fast for 8–10 hours.
What are the early signs that I might need a liver function test?
Fatigue, loss of appetite, nausea, abdominal discomfort, dark-colored urine, and yellowing of the skin or eyes are common signs worth getting checked.
Can alcohol affect my liver function test results?
Yes. Alcohol consumption, even moderate amounts within 24 hours of testing, can temporarily raise liver enzyme levels and affect accuracy.
Can I get a liver function test done at home in Kathmandu?
Yes. Mero Hospital offers home sample collection for liver function tests across the Kathmandu Valley, with reports and doctor consultation available without a clinic visit.
