What is an LFT Test?
A Liver Function Test (LFT) is a panel of blood tests that gives a snapshot of how well your liver is performing. It checks for enzymes, proteins, and substances produced or processed by the liver. These tests help detect inflammation, damage, infections, and conditions like hepatitis or fatty liver early on.
Why is Liver Health So Important?
Your liver is like your body’s chemical processing plant. It filters toxins, helps digest fats, stores vitamins, and even regulates blood sugar. When it’s not working properly, it can affect everything from your energy levels to your skin tone. That’s why regular liver monitoring through tests like LFT is essential.
Common Symptoms That Call for an LFT Test
If you’ve been feeling tired, nauseous, losing weight unexpectedly, or noticing yellowing of the eyes (jaundice), your doctor might suggest an LFT test. These symptoms can indicate underlying liver problems that need attention.
What Exactly Does an LFT Panel Include?
An LFT usually includes ALT, AST, ALP, Bilirubin (total and direct), Albumin, and Total Protein. Each of these elements tells a unique story about your liver’s health — from how well it’s filtering toxins to how efficiently it’s producing proteins.
What Can Abnormal Results Mean?
Elevated liver enzymes might mean your liver is inflamed, often due to conditions like hepatitis, fatty liver, or alcohol-related damage. Low protein levels can suggest your liver isn’t producing enough proteins, affecting your overall nutrition and immunity.
When Should You Get an LFT Done?
Doctors usually recommend LFTs if you’re taking medications that might affect the liver, have a history of liver disease, drink alcohol frequently, or show any signs of jaundice or unexplained fatigue. It’s also common before starting certain treatments or surgeries.
How is an LFT Test Performed?
The test is simple and only requires a small blood sample. You may need to fast before the test, depending on what your healthcare provider advises. The results are usually available within 24 to 48 hours at diagnostic centers like Chughtai Lab, known for reliable testing.
Interpreting the Results with Medical Help
Don’t try to decode your LFT results on your own — always consult a qualified healthcare provider. They can interpret what the levels mean in the context of your health history, lifestyle, and symptoms.
Conditions That an LFT Test Helps Detect
LFTs can help detect a variety of conditions including hepatitis A, B, and C, cirrhosis, non-alcoholic fatty liver disease (NAFLD), liver cancer, and even bile duct problems. Early detection through an LFT test can drastically improve treatment outcomes.
LFTs for People with Chronic Illnesses
If you have diabetes, high cholesterol, or are overweight, your doctor might regularly monitor your liver. These conditions increase the risk of fatty liver disease. An LFT helps in ensuring that these complications are caught and managed early.
LFT in Routine Health Checkups
Even if you don’t have symptoms, adding an LFT to your annual checkup — especially if you’re over 35 or take medication long-term — can act as an early warning system for liver issues.
What Happens After an Abnormal LFT Result?
If your LFT results come back abnormal, your doctor may suggest more detailed tests such as an ultrasound, CT scan, or a liver biopsy. Sometimes lifestyle changes like improved diet, reduced alcohol intake, or medication adjustment are enough.
Can You Improve Liver Function Naturally?
Absolutely! A healthy diet, exercise, avoiding alcohol, and drinking plenty of water go a long way. Foods rich in antioxidants like berries, turmeric, and leafy greens can support your liver. But remember, nothing replaces medical testing and advice.
