Q. What is the purpose of a liver function test (LFT)?
Doctor Answer is medically reviewed by SecondMedic medical review team.
A liver function test (LFT), also known as a liver test or LFT blood test, is a series of blood tests designed to evaluate the health and functionality of your liver. This vital organ plays a critical role in your body, performing tasks like:
-
Nutrient processing: Extracting nutrients from your digested food to fuel your body's processes.
-
Blood detoxification: Filtering out harmful toxins and waste products from your bloodstream.
-
Protein production: Manufacturing essential proteins for various bodily functions, like building and repairing tissues.
-
Bile production: Creating bile, a digestive fluid that aids in fat absorption and waste elimination.
By analyzing the levels of specific enzymes, proteins, and bilirubin in your blood, an LFT offers a window into how efficiently your liver is operating. Here's a closer look at the key purposes of an LFT:
-
Detection of liver disease: An LFT can serve as a screening tool to identify potential liver issues like hepatitis, fatty liver disease, or cirrhosis. Early detection is crucial for timely intervention and management.
-
Monitoring existing conditions: If you have a diagnosed liver ailment, regular LFTs can help your doctor track the disease's progression and assess the effectiveness of any treatment plan in place.
-
Investigating symptoms: If you're experiencing symptoms that could be indicative of liver problems, such as fatigue, nausea, or jaundice (yellowing of the skin and eyes), an LFT can be used to pinpoint the underlying cause.
-
Medication side effect check: Certain medications can have adverse effects on the liver. An LFT can be a valuable tool for monitoring your liver function while taking such medications, allowing for adjustments if necessary.
It's important to remember that an LFT alone might not provide a definitive diagnosis. However, abnormal levels of enzymes or proteins can serve as warning signs, prompting your doctor to recommend further tests for a more comprehensive evaluation.
Overall, LFTs are a crucial tool for safeguarding your liver health. If you have any concerns about your liver function or experience any potential symptoms, discuss it with your doctor to determine if an LFT is recommended for you. Early detection and management of liver problems can significantly improve long-term outcomes.
