Liver function tests are essential medical examinations to assess the liver’s health and its efficiency in performing vital functions. Doctors recommend regular testing, especially for those with chronic diseases or taking medications that affect the liver.

In this article, we guide you through everything you need to know about this important test, from its types to interpreting its results, in a comprehensive guide prepared by “Advanced Cell Laboratories” in Saudi Arabia.

What is a liver function test?

A liver function test is a set of blood tests that measure the levels of specific enzymes, proteins, and substances in the blood to evaluate liver health. This test usually includes:

• Liver enzymes tests: such as AST, ALT, and ALP.
• Bilirubin test: to detect bile and liver problems.
• Albumin and total protein test: to evaluate the liver’s ability to produce proteins.

 

Why are liver function tests important for disease detection?

Liver function tests play a key role in early detection of:

• Chronic liver diseases such as cirrhosis.
• Hepatitis of various types.
• Toxic effects of medications on the liver.
• Detection of lipid disorders, such as liver and cholesterol tests.

Early testing helps avoid serious complications through an appropriate treatment plan designed by the specialist doctor.

Types of liver function tests

Comprehensive liver tests include:

1. ALT (SGPT) – the most accurate enzyme for detecting liver damage.
2. AST (SGOT) – helps determine liver damage extent.
3. ALP – elevated levels indicate bile duct issues.
4. GGT – important for evaluating alcohol or toxin-related liver diseases.
5. Bilirubin – elevated levels cause yellowing of the skin and eyes.
6. Albumin – indicator of liver protein production.
7. Liver & hepatitis tests – includes specific tests like HBsAg and HCV Ab.

 

When should liver function tests be done?

It is recommended in cases such as:

• Presence of symptoms like persistent fatigue, nausea, or yellowing of the skin.
• Regular monitoring for patients with liver diseases.
• After long-term medication use.
• Patients with high cholesterol or triglycerides.
• As part of routine tests, such as fasting liver tests.

 

How to prepare for a liver function test for accurate results?

To obtain accurate results, follow these guidelines:

• Fasting for 8–12 hours before the test (as per doctor’s instructions).
• Avoid taking medications before the test after consulting your doctor.
• Avoid strenuous physical activity before the test.
• Drink enough water.

These steps help minimize external factors affecting test results, especially as medications can influence liver test outcomes.

1. Visit the lab at the scheduled appointment.
2. Blood sample collection from a vein.
3. Sample analysis using the latest equipment.
4. Results available within hours or a working day.

How are liver function test results interpreted?

Result interpretation depends on reference values for each test, e.g.:

• Elevated ALT and AST indicate liver cell damage.
• High ALP and GGT suggest bile duct issues.
• Low albumin may indicate impaired liver function.

Interpretation should be done in consultation with a doctor considering patient history and other factors.

Factors affecting the accuracy of liver function tests

Several factors can affect accuracy, including:

• Taking medications without informing the lab.
• Physical stress before the test.

Blood tests are among the most important medical procedures that help diagnose many diseases and assess overall body health. To ensure accurate results, it is essential to follow specific steps before performing the test.

In this article from “Advanced Cell Labs,” we guide you on how to properly prepare for a blood test, providing key medical tips and instructions.

What is a Blood Test and Why is it Requested?

Blood tests are a set of examinations that measure blood components such as red and white blood cells, hemoglobin, platelets, glucose, lipids, and hormones. These tests are used to detect:

• Anemia
• Liver and kidney diseases
• Diabetes
• Lipid and cholesterol problems
• Infections and inflammations

Why is Proper Preparation Important Before a Blood Test?

• Helps obtain accurate results.
• Prevents misdiagnosis or misleading the doctor.
• Reduces the need for retesting.
• Ensures effective treatment based on correct results.
• Minimizes the impact of food, medications, and physical activity on results.

Essential for certain tests such as

• Fasting blood glucose (8-hour fast).
• Triglyceride test (fast 9–12 hours).
• Vitamin tests (stop supplements before the test).

Which Blood Tests Require Special Preparation?

Some tests require specific preparations, including:

• Fasting blood test: Requires fasting for 8–12 hours.
• HbA1c (A1c) test: Does not require fasting, but the lab should be informed of any medications.
• Blood lipid test: Fast for 9–12 hours before the test.

Do Food and Drinks Affect Blood Test Results?

Yes, food and drinks significantly affect blood test results, especially blood glucose. Here are the details:

How Does Food Affect Results?

• After eating, especially carbohydrate-rich foods (bread, rice, sweets), blood glucose levels rise.

Types of Blood Glucose Tests and Their Relation to Food

1. Fasting Blood Sugar (FBS):

• Used for emergency cases or quick monitoring.

1. Oral Glucose Tolerance Test (OGTT):

• Requires fasting, then the patient consumes a glucose drink, and levels are measured after 1 and 2 hours.
• Often used to diagnose diabetes or gestational diabetes.

1. HbA1c Test:

• Not affected by food.
• Provides average glucose levels over the past 2–3 months.

 

Factors Affecting Blood Test Accuracy

• Eating before the test.
• Stress or lack of sleep.
