Liver Function Test: Why Are They Important?

Liver function test is to check various indexes related to liver functional metabolism through various biochemical test methods to reflect the basic status of liver function. Due to the diverse liver functions, there are many liver function tests.

Liver function examination is an auxiliary method for diagnosing diseases of the hepatobiliary system. If a correct diagnosis of the disease is to be made, a comprehensive analysis must also be carried out in conjunction with the patient's medical history, physical examination, and imaging studies.

A blood test to check liver function can tell if the liver is working properly. There are many blood test items to check liver function, but the most widely used basic test is LFT.

liver function test is a test that can be performed to detect and evaluate liver damage or abnormality by measuring enzymes or proteins produced or excreted in the liver or affected by liver damage.

In addition, it should be pointed out that there are many items of liver function tests, but not every test item needs to be done. Usually doctors will choose a group or several of them based on the patient's medical history and symptoms.

Contra indications:

  1. Do not eat or drink water before the liver function test. You must maintain an empty stomach. The fasting time is generally 8 to 12 hours.
  2. Do not drink alcohol, eat spicy foods, or greasy foods the night before liver function tests. You must do light food.
  3. Do not stay up late the night before liver function tests and do not take medicine, otherwise it may lead to elevated transaminases and abnormal liver function tests.

The liver is responsible for the digestion of food, the accumulation of energy and the removal of toxic substances from the body. If any abnormalities are found in liver function, a liver function test or LFT should be performed to determine the exact cause of the problem.

A liver function test helps the doctor analyze the amount of proteins, enzymes, and some other substances, such as:

  • Total protein
  • The amount of bilirubin (bilirubin is part of the bile juices secreted by the liver during the destruction of red blood cells)
  • Prothrombin time (time required for blood coagulation)
  • Liver enzymes such as ALT (alanine transaminase), AST (aspartate transaminase), ALP (alkaline phosphatase), and GGT (gamma-glutamyl transpeptidase).
  • Albumin (another form of protein).

Liver function tests are blood tests that are a non-invasive way to check for liver disease (for example, hepatitis in a blood donation) and to measure the severity and progression of a disease of the liver and its response to treatment.

Liver tests are done on blood samples and measure the levels of enzymes and other substances synthesized by the liver.

The level of some of these substances makes it possible to assess whether the liver is performing its normal functions of producing protein and secreting bile. The level of other substances can detect the presence and degree of inflammation of the liver.

How to "Check" the Liver? What Tests Should I Take to Diagnose Hepatic Pathologies?

An unchallenged rule of medicine says: the earlier treatment is started, the more chances for its success. In this sense, liver treatment is associated with significant difficulties, since at the initial stages of development of hepatic pathology (except for cases of the severe acute lesion), there is no significant symptomatology. The asymptomatic course of a disease not detected on time can lead to the stabilization of its more complex (chronic) form, which is much worse than the treatable.

Such mild symptoms, such as fatigue, decreased appetite, bitterness in the mouth, a sense of discomfort in the right hypochondrium, can either not attract attention at all, or be misinterpreted. When nausea, yellowing of the skin and sclera, darkening of the urine come, this indicates a far-reaching liver disease, which will not be easy to treat.

How to "check" the liver? What Liver Function Test cost in Delhi should I take to diagnose hepatic pathologies?

In what cases may the liver be checked? To pass the examination of the most critical organs and body systems for preventive purposes is recommended on a regular basis. But several symptoms signal that a check is required as soon as possible. So, the Liver Function Test cost in Delhi should be examined immediately if you notice the following signs of organ dysfunction:

Unpleasant sensations in the area of the lower pair of ribs on the right are one of the first manifestations of problems with the liver. Unaccustomed sensations and a feeling of depression or overcrowding in the liver region can be accompanied by barely noticeable drawing pains, tingling sensations. Usually, they make themselves felt by laughter, loud conversation or screaming, sneezing, sharp slanting to the side, lifting weights, and also after eating fatty, smoked, fried or spicy food.

At first, a new feeling cannot cause pain or tangible discomfort- in that case; they say: "I found out where the liver is." This is a reason to be on the alert, because even mildly expressed symptoms may indicate an initial stage of serious hepatic diseases.

The liver is enlarged in size. The change in the size of the main gland is unmistakably fixed during an ultrasound examination, but you can also notice changes yourself. This will be indicated by the bulging belly without increasing overall completeness and practically without gaining weight, a noticeable symptom in people with lean physique.

Unpleasant taste in the mouth. Patients with chronic hepatic problems note constant dry mouth and bitterness in the tongue, sometimes with a characteristic aftertaste that is defined as "copper." At the same time, an astringent feeling is noted in the mouth; taste sensations are reduced. Habitual food can cause rejection, up to nausea and the urge to vomit.

Weight loss against the background of the asthenic syndrome. This symptom is mostly a consequence of the previous one. The aversion of food, loss of taste, nausea leads to a decrease in diet, which leads to weight loss. In this case, the patient complains of unreasonable irritability, as well as weakness, drowsiness, fatigue, because the energy needs of the body are not met, and the toxic effects of impaired nitrogenous (protein) metabolism increase strongly- with increased concentration of ammonia in the blood, secondary (hepatic) hyperammonemia occurs.

Jaundice is a typical complex of symptoms that is expressed in the icterus of the skin, mucous membranes and eyes proteins, as well as in the dark color of urine, in itching and flaky skin, in chills, bone, and joint pains and is caused by liver problems.
