Liver biopsy is a diagnostic test during which a piece of liver tissue is sampled and studied under the microscope. Such an analysis allows identifying different changes in liver tissues such as damage, inflammation, scar tissue development, and other processes. Liver biopsy is used when there is insufficient information from blood tests and imaging studies about the nature of the disease affecting the liver.
In recent years, due to the advances in the field of medical diagnostics, a number of new methods of non-invasive liver tests have been developed which allow diagnosing the health state of the liver without taking a sample of the tissue. However, there are also specialized blood tests that may be used for assessing the health of the liver. Still, it is unclear whether blood tests will replace liver biopsy in the future.
Which are the common blood tests for liver function evaluation?
Is it possible to diagnose the liver problems using just a single blood test? Yes. Usually, blood tests are used by doctors as a way of starting the evaluation of liver function.
The most common liver function tests are as follows:
1. ALT (Alanine Aminotransferase): Elevated levels may be the sign of liver cell damage.
2. AST (Aspartate Aminotransferase): Elevated levels indicate either liver or muscle injury.
3. ALP (Alkaline Phosphatase): Elevated levels may be associated with problems with bile and liver.
4. Bilirubin: This test helps evaluate the liver's ability to process and remove bilirubin from the body.
5. Albumin: It provides data on the protein-producing capability of the liver.
6. PT (Prothrombin Time): The test evaluates the production of coagulation factors by the liver.
However, despite all the useful information that is provided by liver function tests, they cannot reveal the degree of liver scarring or the cause of some liver diseases.

What are the new developments in noninvasive liver tests?
Is there a way to use advanced liver tests to avoid liver biopsy? With modern technologies, it is possible to measure liver damage and fibrosis using a blood sample and special imaging.
The following tests are considered some of the most useful non-invasive liver tests:
1. FibroScan (Transient Elastography)
FibroScan is a type of non-invasive test that measures the liver stiffness using sound waves. This test helps doctors to estimate the extent of the liver fibrosis, meaning scarring of the liver tissue. Moreover, this test is able to estimate liver fat in certain cases.
2. FIB-4 Score
The FIB-4 score includes information about a person’s age and some results of blood tests, such as AST, ALT, and platelet count. It helps to estimate the probability of advanced liver fibrosis.
3. Enhanced Liver Fibrosis (ELF) Test
The Enhanced Liver Fibrosis Test measures particular proteins that are found in the blood and which are related to liver fibrosis. This test is helpful in determining the probability of having significant liver fibrosis among certain selected patients.
4. APRI
The AST/Platelet Ratio Index (APRI) compares the level of AST and the number of platelets and is used in the estimation of the risk of developing liver fibrosis. This is one of the blood-based assessment methods.
5. Magnetic Resonance Elastography (MRE)
MRE involves the use of magnetic resonance imaging technology to measure liver stiffness.

Is It Possible to Substitute Liver Biopsies with Blood Tests?
Are there any alternatives to the liver biopsy, such as blood tests? No, definitely not.
Noninvasive tests of the liver are important in detecting patients with potential damage or liver fibrosis. In addition, they are necessary for assessing the development of diseases and response to treatment.
Nevertheless, blood tests cannot analyze the liver itself. In certain cases, a liver biopsy should be carried out in order to:
- Determine the origin of liver diseases
- Receive contradictory results of blood and imaging tests
- Suspect the presence of a rare liver disease
- Evaluate the level of inflammation or damage to the organ tissues.
- Make a certain diagnosis to treat a particular liver disease
In conclusion, it is up to a patient what method to use to diagnose liver problems.
Who Would Need Liver Function Tests?
Who should undergo liver tests? There are certain people who would need to have their livers checked for any possible problems.
Such individuals are:
- Those suffering from fatty liver diseases.
- Those who have hepatitis B and/or hepatitis C infections.
- Those suffering from diabetes and obesity.
- Those who drink too much alcohol.
- Those who have changes in liver function test results that are unknown.
- Those who have a family history of liver conditions.
Liver diseases at early stages do not have symptoms.

Conclusion
Is there a way by which a blood test could completely replace a liver biopsy? With advancements in blood tests as well as imaging techniques that do not involve any invasion into the body, liver diseases are being detected easily and without much discomfort on the part of the patient. Tests like FibroScan, FIB-4, APRI, and ELF allow the doctor to determine whether there is any liver fibrosis.
A liver biopsy is still very important for certain situations when there is a need for a microscopic examination of the liver tissue. The diagnostic method would depend on the particular situation of the person.
