Wondering 'What is LFT Test?'

The liver is often called the body’s silent workhorse, working quietly without complaint. From detoxifying harmful substances to aiding digestion, the liver is credited with almost everything. Thus, regular liver monitoring is important. Here, the LFT test comes in.

LFT or Liver Function Tests are blood tests that are done to check the health and overall condition of your liver. This helps your doctor understand how your liver functions overall. At Eskag Sanjeevani, we understand our patients’ needs and ensure they receive the best care and services for their liver problems. [1]

  • Specialised Care and Monitoring: At Eskag Sanjeevani, we have trained professionals who provide you with specialised care and monitoring. We make sure our patients receive the right treatment and help them recover faster.

Understanding LFT: Why is it Necessary?

Are you wondering what the LFT test is? It is simply a diagnosis of your liver’s current state and a way to detect any signs of damage. The liver is responsible for a number of things, from producing bile, storing vitamins and iron, regulating blood levels, and clotting blood. If the liver cells are inflamed or damaged, they leak very large amounts of certain chemicals into the bloodstream.[1]

The LFT test is necessary to determine these levels, which in turn helps identify conditions like hepatitis, fatty liver, and even jaundice. This test is often prescribed if you have a family history of liver issues, consume alcohol or take any medicine that might have side effects affecting the organ. Because the liver has an amazing ability to regenerate, early diagnosis through a standard LFT test can literally be a lifesaver. At Eskag Sanjeevani, we understand how vital your liver health is, and we want to provide the best for your overall well-being. [3]

The Procedure of Liver Test

After understanding what the LFT test is, it becomes important to understand its procedure. Many patients get worried and anxious about blood tests, but learning and understanding how to test liver function can keep you calm. The LFT test is a simple procedure, much like any other routine blood test. At Eskag Sanjeevani, we have trained medical experts and other professionals who make sure you’re comfortable throughout the entire procedure.

To begin with, a trained professional will draw blood from your veins like any other blood test, and it hardly takes five minutes for the entire process. Once the blood sample is ready, it is sent to our lab where experts check the levels of different liver markers. When you’re learning how to test liver function, it’s also helpful to know that you won’t be waiting long because results are usually ready within 24 to 48 hours. This allows you to sit down with your specialist at Eskag Sanjeevani quickly to discuss the next steps for your health.

Preparing for the Screen: Does LFT Require Fasting?

One of the most asked questions by patients is “Does LFT require fasting?” Fasting is not usually mandatory for the LFT test. Still, at times lipemia (excess fat in the blood) may affect the accuracy of the results, so your doctor may suggest fasting for 8-12 hours.[1]

Guidelines to follow before the LFT Test:

  • Duration: You are typically asked to fast for 8 to 12 hours before the blood is drawn.
  • Limited Liquids: You can usually drink plain water, but you should avoid coffee, tea, juice, and any other beverages.
  • Medication: Always inform your doctor about any medicines, supplements, or prescriptions you are taking, as these can affect LFT test results more than any food does.[2]You need to be consistent with these steps, as consistency in preparation ensures that the LFT test provides a clean, accurate result, making it easier for doctors to compare your results over time without interference from dietary factors.

Special Consideration: LFT Test in Pregnancy

Now, a major concern is whether it would be right to do an LFT Test in Pregnancy. Pregnancy brings massive physiological changes in a woman’s body, and the liver is not an exception. Doctors often monitor the LFT test in pregnancy to rule out conditions specific to gestation, such as Intrahepatic Cholestasis of Pregnancy (ICP) or even HELLP syndrome.

While slight fluctuations in liver enzymes can be normal because of the increased workload on a mother’s body, a significant spike in the test requires immediate medical attention. It is an extremely important part of prenatal care that ensures both the mother and the baby remain safe from complications that could affect blood clotting or toxin filtration.[4]

Results and the Next Steps

Once you receive your report, you might see terms like albumin, bilirubin, and alkaline phosphatase. A high or low value doesn’t always mean there is a disease, as it is just a piece of the puzzle. Your doctor will look at the LFT test results along with your physical symptoms and medical history. [1]
If your LFT test shows abnormalities, the next steps might include an ultrasound, a lifestyle adjustment, such as a cleaner and healthier diet, or further specialized testing.

Remember, the LFT test is a tool for empowerment, helping you make adjustments before minor issues become major health hurdles. Eskag Sanjeevani makes sure to provide accurate results so that the next steps can be taken to ensure faster recovery. [4]
