Your liver is one of the most hardworking organs in your body silently performing over 500 vital functions every single day. From detoxifying your blood to helping in digestion and storing essential nutrients, the liver does it all. Yet, most of us don’t think about liver health until something goes wrong.
That’s where the Liver Function Test (LFT) comes in. This simple blood test can reveal a lot about your liver’s condition before symptoms even appear. Let’s explore why it’s done, how it works, and what you can learn from your results.
Why Is the Liver Function Test (LFT) Done?
Doctors recommend an LFT for several important reasons not just when you’re sick. Here’s why it matters:
1. Early Detection of Liver Disease
Many liver problems, like hepatitis or fatty liver, develop quietly. The LFT can detect abnormalities long before symptoms show up, allowing for early treatment.
2. Monitoring Ongoing Health Conditions
If you’re already diagnosed with a liver condition, an LFT helps track your progress and monitor how well your treatment is working.
3. Evaluating Medication Side Effects
Certain medicines can stress or damage the liver over time. Regular LFTs help ensure your medication isn’t harming your liver.
4. Checking Alcohol or Toxin Impact
For individuals who consume alcohol frequently or are exposed to chemicals, LFTs can reveal the liver’s response to toxins.
5. Before or After Surgery
Doctors often require an LFT before major surgeries to ensure your liver can process anesthesia and medications safely.
What Does an LFT Measure?
A Liver Function Test measures the levels of several enzymes and proteins in your blood. Each one gives a clue about how well your liver is working:
| Parameter | What It Indicates |
|---|---|
| ALT (Alanine Aminotransferase) | High levels suggest liver cell injury. |
| AST (Aspartate Aminotransferase) | Indicates inflammation or damage to liver tissue. |
| ALP (Alkaline Phosphatase) | Helps diagnose bile duct problems or bone disorders. |
| Bilirubin | Elevated bilirubin causes jaundice; signals liver or bile duct issues. |
| Albumin & Total Protein | Reflect the liver’s ability to produce essential proteins. |
| Gamma GT (GGT) | Increases due to alcohol or toxin exposure. |
These readings, taken together, give a detailed picture of your liver’s health.
How Is the LFT Done?
The test is quick, simple, and requires no major preparation.
Here’s how it works:
- Sample Collection: A phlebotomist takes a small blood sample from your arm.
- Analysis: The sample is sent to the lab for analysis using advanced diagnostic equipment.
- Results: You usually receive your results within 24 hours.
- Interpretation: A doctor reviews the values to check if any enzyme levels are higher or lower than normal.
Tip: It’s best to avoid fatty meals and alcohol 24 hours before the test for the most accurate results.
Symptoms That Indicate You Might Need an LFT
You don’t always need to wait for a doctor’s recommendation watch out for these signs and get tested if they appear:
- Persistent fatigue or weakness
- Yellowing of the eyes or skin (jaundice)
- Loss of appetite or nausea
- Dark urine or pale stool
- Swelling in your abdomen or legs
- Unexplained weight loss
Ignoring these symptoms could allow liver disease to progress silently.
