How can i get a lft?

While some of these tests measure how well the liver performs its normal functions, others measure enzymes that liver cells release during liver damage or disease.

LFTs help diagnose and monitor liver disease or damage. If the levels are higher or lower than the normal range, it indicates that a person’s liver is not functioning optimally.

A physician requests an liver function test to establish the presence of damage or inflammation in the liver. LFTs help to:

Having an LFT done doesn’t require any special preparation. The technician can collect the sample at any time of the day. Some medicines may affect the test outcomes, so it may be helpful to let your physician know about all prescription and non-prescription drugs you take.

Your blood will be drawn in a hospital or a diagnostic centre. To administer the test:

An LFT cannot provide a diagnosis independently but can provide important clues about potential liver function problems.

Here are the standard tests included in an liver function test panel:

The results mentioned here vary from laboratory to laboratory and might be slightly different for women and children.

There is no specific condition when this test should be avoided. Inform your doctor about any medications, prescription or over-the-counter medications, including herbal supplements, that may affect the liver function test results.

Some common causes which can result in high values for liver function tests are:

Fatty liver disease develops when fat builds up in the liver. If this build-up is due to long-term alcohol consumption, it is known as alcoholic fatty liver disease.

When alcohol is not a causative factor for fat accumulation in the liver, the condition is called non-alcoholic fatty liver disease (NAFLD). People who have metabolic syndrome are at a higher risk of NAFLD.

Although fatty liver may primarily be asymptomatic, it may cause tiredness and pain on the right side of the abdomen.

Metabolic syndrome encompasses a group of symptoms that enhance cardiovascular risk. These symptoms include:

The physician may get an LFT done for individuals with two or more of these symptoms.

Hepatitis means inflammation of the liver. There are several different strains of hepatitis-causing viruses, which are called A, B, C, D, and E. The symptoms resulting from infection by all these strains are similar.

A physician may test a person with symptoms of hepatitis to check for elevated liver enzymes.

Inflammation of the liver can occur due to drinking too much alcohol (alcoholic hepatitis) or indulging in substance abuse (toxic hepatitis). All forms of hepatitis have similar symptoms. In a history of alcoholism or substance abuse, the physician may get an liver function test done to check for disease onset and progression and monitor treatment.

Cirrhosis is liver damage caused by chronic fibrosis, scarring, and shrinkage, eventually leading to liver failure.

Untreated hepatitis or fatty liver disease has a high risk of progressing to cirrhosis. Patients with cirrhosis experience fatigue, itching, and other symptoms common to hepatitis and fatty liver disease.

A physician may check liver enzyme levels to assess progression and monitor response to therapeutic interventions.

Therapeutic intervention for elevated liver enzymes will focus on managing the underlying condition causing the increased levels.

For NAFLD, individuals can work with their physician to make lifestyle changes such as:

A nutritionist or personal trainer can help individuals stay compliant with their diet and weight loss plan.

If a person has alcoholic fatty liver disease, the doctor will provide guidance, education, and support about decreasing alcohol intake in any form.

The treatment strategy for metabolic syndrome is similar to fatty liver disease:

A physician will recommend the following strategies for acute hepatitis:

Treatment for long-term ineffective hepatitis usually includes an antiviral medication regimen.

Treatments for chronic alcoholism or drug use disorder include:

Cirrhosis is permanent liver damage, so it is not always treatable. However, the underlying cause of liver dysfunction is usually responsive to treatment.

Prompt diagnosis and treatment of infectious, inflammatory, and chronic metabolic conditions that affect the liver can help prevent progression to cirrhosis.

Interventions such as a modified diet, exercise and weight loss, and reduced alcohol consumption can reduce the risk of progressive liver damage and dysfunction.

Who will still get free LFTs?

The three eligible categories for free LFTs are:

Health and social care staff will continue to have access to free LFTs through their workplace.

Patients with a planned hospital admission will have their LFTs provided by the Preoperative Assessment Clinic.

What if I’m not eligible for free LFTs?

If you are not in any of the three eligible categories then you will be able to purchase LFTs from local pharmacies and some other high street retailers.

How do I check if I’m classed as high-risk?

A list of conditions that would identify individuals as high-risk can be found on the antivirals webpage. If you suffer from one of these conditions you are classed as high risk, and should contact your GP to confirm your status and receive a letter confirming you are eligible for free LFTs.

You can then take this letter to your local pharmacy to collect your free LFTs.

Where will I be able to purchase LFTs?

You will be able to purchase LFTs from local pharmacies and some other high street retailers.

Do I still need to do an LFT before attending a healthcare setting?

No. Visitors to health and social care settings – including care or residential homes, dentists, GP surgeries or day clinics, will no longer be required to do an LFT test before attending unless you are symptomatic.

Liver function tests are used to measure specific enzymes and proteins in your blood.

Having atypical results on any of these liver tests usually requires a follow-up to determine the cause of the atypical characteristics. Even mildly elevated results can be associated with liver disease.

Common liver function tests include:

Alanine transaminase (ALT) is used by your body to metabolize protein. If the liver is damaged or not functioning properly, ALT can be released into the blood. This causes ALT levels to increase. A higher result than what’s typical on this test can be a sign of liver damage.

It’s estimated that about 10 percent of people in the United States have elevated ALT levels.

Aspartate aminotransferase (AST) is an enzyme found in several parts of your body, including your:

When the liver is damaged, AST can be released into the bloodstream. A high result on an AST test might indicate a problem with the liver or muscles.

Since AST levels aren’t as specific of a marker for liver damage as ALT, it’s usually measured together with ALT to check for liver problems. For example, a high AST:ALT ratio may indicate alcoholic liver disease.

Alkaline phosphatase (ALP) is an enzyme found in your bones, bile ducts, and liver. An ALP test is typically ordered in combination with several other tests. An ALP test can be used to evaluate the bile duct system of the liver.

Albumin is the main protein made by your liver. It performs many important bodily functions.

For example, albumin nourishes your tissues and transports hormones, vitamins, and other substances throughout your body. An albumin test measures how well your liver is making this particular protein.
