What Are Liver Function Tests?
Liver function tests are simple blood tests that check how well your liver works. Doctors often call them “liver blood tests.” These tests measure different chemicals and proteins in your blood. Because your liver does many important jobs, these tests can show if it is healthy or if there is a problem. For example, they can help find liver damage, infection, or disease.
Why Are Liver Function Tests Important?
These tests are important because your liver helps your body in many ways. For instance, it removes toxins, makes proteins, and stores energy. If your liver is not working well, you may not feel sick at first. However, liver problems can get worse over time. Early testing can help find issues before they become serious. In addition, liver function tests can help your doctor check how well treatments are working.
Common Types of Liver Function Tests
Doctors use several tests to check your liver. Each test looks at a different part of liver health. Here are some common types:
Doctors may order one or more of these tests based on your symptoms.
How to Prepare for a Liver Function Test
Preparing for liver function tests is usually easy. Still, you should follow your doctor’s advice. Sometimes, you may need to fast for several hours before the test. In other cases, you can eat and drink as usual. Always tell your doctor about any medicines or supplements you take. Some drugs can affect your test results. If you have questions about liver test preparation, ask your healthcare provider.
What to Expect During and After the Test
During the test, a nurse or technician will take a small blood sample from your arm. The process is quick and usually takes less than five minutes. You may feel a small pinch, but most people find it easy. After the test, you can return to your normal activities. Sometimes, you may have a small bruise or soreness where the needle went in. However, these side effects go away quickly.
Understanding Your Results
When your results are ready, your doctor will explain what they mean. Normal liver test values can vary by age, gender, and lab. If your results are outside the normal range, it does not always mean you have liver disease. Many things, like medicines or infections, can change your results. Your doctor may order more tests if needed. Always discuss your results with a healthcare professional for the best advice.
When to See a Doctor
If you have symptoms like yellow skin or eyes, dark urine, or pain in your upper right belly, see a doctor. Also, if you have a family history of liver disease or use medicines that affect the liver, regular testing may help. Early care can prevent serious problems. Do not wait if you feel unwell or notice changes in your health.
