Description
Serum, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
A blood sample is required for a liver function test without proteins. This sample is typically drawn from a vein in your arm.
Test Time:
The results for a liver function test without proteins are usually available within a day or two after the blood sample is collected.
Test Normal Range:
The normal range for liver function test results can vary between laboratories, but it typically includes various parameters such as:
Alanine Aminotransferase (ALT): Normal range often falls between 7 to 56 units per liter (U/L).
Aspartate Aminotransferase (AST): Normal range is commonly between 10 to 40 U/L.
Alkaline Phosphatase (ALP): Normal range varies but is typically between 20 to 140 U/L.
Total Bilirubin: Normal range can range from 0.3 to 1.2 milligrams per deciliter (mg/dL).
Direct Bilirubin: Normal range often falls below 0.3 mg/dL.
Gamma-Glutamyl Transferase (GGT): Normal range varies but is usually between 9 to 48 U/L.
Albumin: Normal range typically ranges from 3.4 to 5.4 grams per deciliter (g/dL).
What is the Test?
The liver function test without proteins, also known as a liver function panel, measures various substances in the blood that are produced or processed by the liver. This panel typically includes tests for enzymes, bilirubin, and albumin. It provides valuable information about how well the liver is functioning.
Test Procedure:
A healthcare provider will clean the area, usually the inside of your elbow, where the blood will be drawn. They will insert a needle into a vein to collect a blood sample. The collected blood is sent to a laboratory for analysis. In the lab, specialized equipment measures the levels of various liver-related substances in the blood sample.
When to Take the Test:
A liver function test may be ordered as part of a routine check-up, to monitor liver health in individuals with liver diseases, or to evaluate the effects of medications on the liver. Your healthcare provider will determine when and how often you should take this test based on your medical history and specific health needs.
Who Should Take This Test:
Individuals with symptoms or risk factors for liver disease, such as jaundice, abdominal pain, unexplained fatigue, or a history of alcohol abuse, should consider this test. Additionally, it is commonly used to monitor liver function in individuals with liver conditions, including hepatitis, cirrhosis, or those taking medications that may affect the liver.
Precautions for Exceptional Cases (Pregnancy, etc.):
Inform your healthcare provider if you are pregnant or planning to become pregnant, as some liver function parameters may change during pregnancy. Your provider will interpret the results accordingly. Also, mention any medications or supplements you are taking, as certain drugs can affect liver function.
FAQs (Frequently Asked Questions):
Q1: What can cause abnormal liver function test results?
A: Abnormal results may be due to various factors, including liver diseases, infections, medications, alcohol use, or other underlying health conditions. Further evaluation is often needed to determine the cause.
Q2: Can I eat or drink before a liver function test?
A: Fasting is not typically required for a liver function test without proteins. However, it’s a good idea to follow any specific instructions provided by your healthcare provider or the testing facility.
Q3: Are there any risks associated with a liver function test?
A: The test itself is relatively low-risk. You may experience minor discomfort at the needle insertion site, and there is a small risk of bruising or bleeding. In very rare cases, an infection may occur.
Q4: Can I continue taking my regular medications before the test?
A: In most cases, you can continue taking your regular medications before a liver function test. However, it’s important to inform your healthcare provider about all medications and supplements you are taking, as some can affect the test results.
Q5: What do abnormal liver function test results indicate?
A: Abnormal results may suggest liver damage or dysfunction. However, further evaluation, which may include additional tests and medical assessment, is necessary to determine the specific cause and severity of the condition.
