Which Blood Test Is For Liver Function – Do you feel unusually tired and frail? Does your appetite steadily decrease for no apparent reason? It’s time to do a liver function test! The liver is the largest organ in the body. It is responsible for important functions such as energy storage, detoxification, and the production of biochemicals that aid in digestion and metabolism. The liver can be overworked due to eating too unhealthy or an underlying medical condition.

A liver function test (LFT) can give you insight into the health of your liver and offer early diagnosis of potential problems if any. Do you want to know more about LFT and why it is important? Read on to learn the top 7 benefits of getting a liver function test!

Which Blood Test Is For Liver Function

The liver is a key organ in our body and is responsible for the vast majority of digestive and defense functions. As such, we need to regularly check the liver to make sure everything is working properly. One of the ways to do this is through liver function tests, which measure enzymes and proteins found in the liver tissue. These tests can help us determine if the liver is working at optimal efficiency or if there are existing problems that we should be aware of. Liver function tests are not always necessary, but they can help ensure that liver health remains strong.

The liver plays a key role in the body’s metabolic functions, so it is essential to know about different liver function tests. Specifically, LFTs check for liver damage and disease by measuring specific enzymes or proteins found in liver cells. These tests provide a broad overview of liver enzyme activity and can also help diagnose common liver diseases such as hepatitis, cirrhosis and fatty liver diseases. The LFT includes an alkaline phosphatase test, an alanine aminotransferase test, an aspartate aminotransferase test, a gamma-glutamyl transferase test, a prothrombin time test, an albumin test, and a total bilirubin test. Together, these tests provide important insights into a person’s liver health and overall well-being.

The preparation for a liver function test is simple and relatively painless. The procedure usually involves drawing blood from a vein in the arm and sending it to a laboratory for analysis. In addition, it is recommended to fast 8-12 hours before the draw, as this helps ensure accurate results. Overall, it’s a simple process that can provide valuable information about the health of your liver.

A timely LFT can provide insightful information about the health of your liver, making it easier to take preventive measures if needed.

Abnormal LFTs can indicate various conditions, such as liver cirrhosis, hepatitis, fatty liver disease, or even cancer. However, due to the wide variety of diseases that affect the organ, it can be challenging to determine which condition caused these symptoms. Common metabolic conditions such as diabetes and hyperlipidemia may also be to blame. Other options include drugs and medications with hepatotoxic effects, alcoholism, or autoimmune disorders such as primary biliary cholangitis or sclerosing cholangitis. While abnormal LFTs often indicate a possible medical problem affecting the liver, further testing is required to accurately determine the cause.

There are times when it may not be appropriate to take the test; For example, if a person has recently taken medication such as acetaminophen or consumed food containing large amounts of alcohol. Because these substances can increase certain levels of enzymes found in LFTs, they may show abnormal results that do not necessarily indicate underlying liver problems. In addition, after exercise or physical activity, it is best to wait two hours before taking an LFT so that the results more accurately reflect liver health.

To get the most accurate results from a liver function test, your doctor may tell you not to eat or take certain medications for 8-12 hours after the test is performed. Make sure that all fasting instructions are followed strictly for accurate findings!

From coffee consumption, cigarette smoking and alcohol drinking, any of these daily habits can affect your liver function tests. It is important to fully understand the effects these activities have on the levels of LFT-related enzymes, and further research is needed to fully understand the mechanism by which they may affect the expression of these enzymes.1. A liver function test (LFT) is a medical test used to assess the health of the liver. When consuming chronically excessive levels of alcohol, it can cause liver damage. Therefore, liver health analysis can help determine whether a person is suffering from liver damage as a result of chronic excessive alcohol consumption during the last monitored period.

When using the LFT test to monitor chronic excessive alcohol consumption, three “markers” are considered; aspartate aminotransferase (AST), alanine aminotransferase (ALT) and gamma-glutamyltransferase (Gamma GT). These “markers” are provided by scientific literature to be most affected by alcohol consumption.

It is important to note that elevated LFT results can be due to chronic excessive alcohol consumption and also due to other medical conditions and factors such as certain medications or drugs, cirrhosis, hepatitis and other liver diseases or a damaged liver.

The LFT result for the blood sample shows a Gamma GT reading of 41 IU/L. Therefore, the result is within the range of a healthy adult and does not imply liver damage. The levels of two other liver enzymes (transaminases) were as follows:

2. Carbohydrate-deficient transferrin (CDT) is a test specifically used to monitor chronic excessive alcohol consumption. CDT is useful when determining whether alcohol has been consumed excessively over consecutive days (approximately 4-7 days), rather than a “one-off” binge session.

It is important to note that CDT can be affected by other medical conditions, which should be taken into account when reading the test results.

The level of CDT results in the blood sample was 2.4%, which falls outside the range of a healthy person and indicates that up to four weeks before the sample was collected, excessive alcohol had been consumed.

3. A complete blood count (FBC) is a medical test used to assess a person’s overall health. This is achieved by assessing the concentrations of different types of blood cells (and some proteins). To monitor excessive alcohol consumption, the Mean Corpuscular Volume (MCV) is considered, which indicates increased blood cell volume and can therefore indicate excessive alcohol consumption.

It is important to note that certain nutritional deficiencies such as vitamin B12 or folic acid can cause an increase in MCV.

The FBC result for the blood test shows an MCV reading of 95.0 fL and does not suggest long-term alcohol abuse.

Decoding The Basic Liver Function Tests

We recommend testing LFT and CDT together unless court ordered. We consider the sensitivity of the alcohol liver function test to be low, which we no longer recommend testing on its own, because we do not believe that the results of family cases are important – often involving children or allegations of abuse should be based on them. A test with such low sensitivity (not specific for alcohol). Also, we would never recommend testing FBC itself. All in all it is better to check all three together.

The phosphatidylethanol test, known as the PEth test, is a highly reliable blood test that allows detection of excessive alcohol use up to 28 days before the sample is collected. With a sensitivity and specificity rate of over 99%, it is widely adopted as a replacement for CDT, LFT and MCV. It is a direct biomarker of alcohol use, meaning it is produced only in the presence of ethanol and can therefore be used to determine abstinence and excessive consumption, as well as a variety of classifications in between; occasionally or socially.

We have also found the PEth test to be a good tool for monitoring consumption over an extended period of time instead of potentially invasive monitoring techniques – where there is also the opportunity for disruption.

The PEth results for the blood sample show a reading of 81 µg/L. This level indicates that the donor was recently exposed to a moderate level of alcohol, compared to other PEth tests performed in the laboratory.

Reasons Why You Should Take A Liver Function Test

LFT, CDT and FBC tests are indirect biomarkers for alcohol. This means that they occur naturally in the body and are not produced solely from alcohol consumption. As a result, traditional blood tests are not suitable for monitoring alcohol abstinence. These tests can only advise if it is likely that alcohol has been consumed excessively. Because PEth is a direct biomarker and therefore only produced in the presence of alcohol, PEth is the only blood alcohol marker that can be used to monitor alcohol abstinence.

None of the traditional tests is a direct biomarker of alcohol consumption. This means that while they measure changes in the body that can be affected by excessive alcohol consumption, these changes can have a multitude of other contributing factors. Other factors include age, gender, sex, underlying genetic conditions, other infectious diseases, general fitness and even menstruation. When the tests are combined (i.e. LFT, CDT and FBC), the accuracy in distinguishing excessive alcohol consumption only increases to about 77% compared to the PEth test
