<h2 style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">What is a liver functioning test?</span></h2>
<hr />
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">Liver function tests are essentially <a href="https://newsforpublic.com/blood-sugar-test-machine/">blood tests</a>. These tests are prescribed to detect malfunctions in the liver, a vital reddish-brown organ in the digestive system. The liver is responsible for regulating blood circulation and metabolism in addition to acting as a remover of toxins in the blood. </span></p>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;"> </span></p>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">The detection is done by measuring the status of liver enzymes alongside bilirubin, a yellow pigment formed when RCBs are broken down in the liver, in the blood serum. The results from the </span>liver functioning test<span style="color: #0e101a;"> form the basis of diagnosis for liver disease, although they do not indicate what liver dysfunction occurred.</span></p>

<h2 style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">Why is the LFT test important?</span></h2>
<hr />
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">The liver is the lifeline of a person. It has enzymes that help in the metabolism of fats and proteins. The liver spleen is crucial for regulating the haemoglobin levels of the blood. Liver dysfunction can be fatal for the person and hence detected via <strong>LFT test </strong>at the earliest.</span></p>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;"> </span></p>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">Today alcohol and drug consumption have increased drastically. Due to the fast-paced lifestyle, people are becoming obese too. Consequently, the population is becoming more and more vulnerable to liver diseases.</span></p>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;"> </span></p>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">The situation worsens since the early stages of liver dysfunction do not have any symptoms. As a result, taking preventive measures on time becomes hard.</span></p>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;"> </span></p>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">A <strong>liver functioning test </strong>can detect liver dysfunction even before symptoms surface. Hence getting one if you find yourself vulnerable is crucial. Otherwise, persistent liver damage can cause cirrhosis and eventually lead to death. </span></p>

<h2 style="margin: 0in 0in 0.0001pt;"><span style="color: #0e101a;">When are liver function tests prescribed? </span></h2>
<hr />
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">A physician suggests taking a <strong>liver functioning test</strong> for several diseases like:</span></p>
<ul>
<li style="text-align: justify;"><span style="color: #0e101a;">Hepatitis A, B, and C</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Liver disorders</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Hypertension</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Liver cirrhosis or failure</span></li>
</ul>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">Furthermore, the test is prescribed when vulnerable to developing liver infections. </span></p>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;"> </span></p>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><strong><span style="color: #0e101a;">These circumstances include:</span></strong></p>
<ul>
<li style="text-align: justify;"><span style="color: #0e101a;">Obesity</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Alcoholism or any substance abuse</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Family history of liver diseases</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Genetic disorders. Especially in the case of alpha 1AT deficiency.</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Drugs used to contain HIV can cause side effects in the liver. Thus, if somebody has HIV, they ought to observe the side effects on a routine basis.</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;"><strong>Medicines:</strong> Antifungal drugs, steroids, niacin, and medicines that have methotrexate or azathioprine can have side effects on the liver. </span></li>
<li style="text-align: justify;"><span style="color: #0e101a;"><strong>Diseases:</strong> Diabetes, anaemia, gall bladder dysfunction.</span></li>
</ul>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">A <strong>liver functioning test </strong>is prescribed by the doctor when you show symptoms like:</span></p>
<ul>
<li style="text-align: justify;"><span style="color: #0e101a;">Vomiting bile or blood.</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Weakness along with dizziness and fatigue</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Sudden loss in weight.</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Excruciating pain in the abdomen or belly.</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Yellow eyes and skin.</span></li>

<li style="text-align: justify;"><span style="color: #0e101a;">Diarrhoea</span></li>
</ul>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">After the test results are out, you must immediately see your doctor for further evaluation.</span></p>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;"> </span></p>
<h2 style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">What happens in an LFT?</span></h2>
<hr />
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">A<strong> </strong></span><a href="https://www.asterlabs.in/book-a-test/tests/biochemistry/liver-function-test-lft" target="_blank" rel="noopener">Liver function test</a><strong><span style="color: #0e101a;"> </span></strong><span style="color: #0e101a;">involves taking a blood sample first. When you reach the laboratory or hospital, the staff member would get you seated and attach a band to the upper arm at the joint. A sterilized needle is used to extract a few ml of blood from your vein, and the sample is put into a vial. </span></p>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;"> </span></p>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">From here, the sample is tested to measure the levels of different substances like:</span></p>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;"> </span></p>
<ul>
<li style="text-align: justify;"><span style="color: #0e101a;">Albumin: This is a protein that is made by the liver. It is functional in transporting vitamins and enzymes, as well as hormones via the bloodstream.</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Enzymes, such as alkaline phosphatase, alanine transaminase, and gamma-glutamyl transferase, are produced by the liver.</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Lactate dehydrogenase, an enzyme formed in reaction to damage to the body.</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Prothrombin time or PT. This is a type of protein used during blood clotting.</span></li>
</ul>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">When blood is extracted, you might feel a slight sting caused by the needle. Otherwise, the test has no complications. Some people, however, might feel a bit lightheaded for some time. In such a situation, you must sit at the facility before taking your leave for home.</span></p>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;"> </span></p>
<h2 style="margin: 0in 0in 0.0001pt;"><span style="color: #0e101a;">What can high levels of each substance indicate?</span></h2>
<hr />
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">High levels of these substances indicate:</span></p>
<ul>
<li style="text-align: justify;"><span style="color: #0e101a;">Alanine transaminase and Aspartate aminotransferase: Liver damage</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Alkaline phosphatase: Liver inflammation, blockage of bile ducts, bone disease.</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Bulbirin: Compromised liver function or mononucleosis</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">Gamma-glutamyltransferase: Liver damage and/or bile duct damage.</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">PT: Compromised liver function, blood clotting disorder, or Vitamin K deficit. </span></li>
</ul>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">Furthermore, low albumin levels are a sign of cirrhosis, liver infection, and liver inflammation alongside kidney disease.</span></p>
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;"> </span></p>
<h2 style="margin: 0in 0in 0.0001pt;"><span style="color: #0e101a;">What do you need to know/do before the test?</span></h2>
<hr />
<ul>
<li style="text-align: justify;"><span style="color: #0e101a;">Before taking the test, you will be asked to fast for at least 8 hours. Hence, it is the wisest to go in the morning after you wake.</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">The test takes the blood sample from the upper arm. Hence, wearing half-sleeved attire will be convenient. If it is winter, wear something warm over a half sleeve shirt/T-shirt.</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">The needle might sting if you are too stressed. Hence, keep calm so that your muscles can relax and hurt less. This will also make the process smoother. If you are afraid of needles, you can always revert or close your eyes.</span></li>
<li style="text-align: justify;"><span style="color: #0e101a;">The doctor might ask you to abstain from taking medications before the test.</span></li>
</ul>
<h2 style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">Is the test risky?</span></h2>
<hr />
<p style="margin: 0in 0in 0.0001pt; text-align: justify;"><span style="color: #0e101a;">The test is harmless and does not involve any health risks. However, you might get infected if the equipment used for extracting blood is not sterilized well. Hence, it is crucial to choose a reputed facility.</span></p>
