Understanding Liver Function Tests
Liver function tests are essential diagnostic tools that help determine the health of your liver by examining various enzymes and proteins. These tests can detect potential issues early on, allowing for timely intervention and treatment to prevent further damage to this vital organ.
Importance of Liver Health in Overall Well-being
The liver plays a crucial role in maintaining overall health as it is responsible for more than 500 bodily functions, including filtering out toxins from the foods you eat and liquids you drink. A healthy liver contributes significantly to our well-being; therefore, it's important to monitor its condition regularly through liver function tests.
Key Components of a Comprehensive Liver Panel Test
A comprehensive liver lab test panel looks at several variables and enzymes that provide valuable information about the current state of your liver's health. Some key components include:
- Total Protein: Essential for tissue health and regeneration.
- Albumin: An important protein that indicates heart or kidney problems.
- Globulin: Produced by the liver and immune system, helps fight bacteria and viruses.
- Bilirubin Levels: Indicates bile flow obstruction or jaundice development due to excessive toxins or drugs present in the bloodstream.
- Alkaline Phosphatase (ALP): Helps identify bone problems or potential liver issues.
- Lactate Dehydrogenase (LDH): Primarily found in heart muscle, high levels may indicate heart problems.
In addition to these key components, other enzymes such as aspartate aminotransferase (AST), alanine transaminases (ALT), and gamma glutamyl transpeptidase (GGT) are also examined to determine liver health. High levels of these enzymes may indicate liver problems caused by excessive alcohol consumption, toxins, or drugs.
Regular monitoring with liver function tests is crucial for maintaining overall health since some symptoms may not appear until it's too late. Early detection allows doctors to recommend therapies or lifestyle changes that can help mitigate issues while giving the liver an opportunity to regenerate itself.
When should you get tested?
It's always better to do a hepatic function panel sooner rather than later. Although some liver issues may not cause any symptoms, it is still advisable to get tested regularly. It's recommended to do a liver test panel periodically when taking certain medications that might affect your liver, as well as if you see apparent symptoms of liver problems such as yellowing of the eyes.
Understanding liver function tests is essential to maintaining overall health and wellness. Enzymes and proteins examined in a liver panel test provide an even more detailed look into the functionality of this vital organ.

Enzymes and Proteins Examined in a Liver Panel Test
A comprehensive liver lab test panel looks at several variables and enzymes, each providing valuable information about the current state of your liver's health. Let's discuss some of these key components:
This test measures the total amount of protein in your body, which is essential for tissue health and regeneration. Abnormal protein levels may indicate malnutrition or muscle wasting.
As one of the most important proteins in the human body, albumin levels can reveal potential issues with your heart or kidneys. Testing for albumin is crucial to determining liver health.
The liver and immune system both produce this protein, which aids in battling viruses and bacteria. Low globulin levels may signify poor liver function or a weakened immune system.
- Total Bilirubin: This cellular antioxidant is secreted as a result of red blood cell breakdown. High bilirubin levels can cause jaundice (yellowing of the eyes or skin) due to obstructed bile flow or an overwhelmed liver.
- Direct Bilirubin: Also known as conjugated bilirubin, this type specifically indicates whether there's an issue with bile secretion from the liver into the intestines.
- Indirect Bilirubin: An elevated level suggests that there might be excessive red blood cell destruction happening within your body.
Liver Enzymes: Alkaline Phosphatase, Lactate Dehydrogenase, Aspartate Aminotransferase and Alanine Transaminases
- Alkaline Phosphatase (ALP): High ALP levels may indicate bone problems or liver damage.
- Lactate Dehydrogenase (LDH): Found in heart muscle tissue, abnormal LDH levels can signal potential heart issues.
- Aspartate Aminotransferase (AST): Low levels are normal; however, high AST levels suggest muscle damage or liver problems due to excessive alcohol consumption. In such cases, patients should stop drinking and retest after a few weeks.
- Alanine Transaminases (ALT): This enzyme is commonly found in the liver. Elevated ALT is a sign of potential liver damage from toxins, drugs, or alcohol.
Important note: Resistance exercise can increase liver enzymes.
A study performed in Sweden and published in the February 2008 issue of the British Journal of Pharmacology was designed to investigate the effect of intensive muscular exercise (weightlifting) on a single occasion on liver enzymes in healthy men not used to performing weightlifting on a regular basis. A secondary objective was to investigate the effect of a single occasion of intensive muscular exercise (weightlifting) on clinical chemistry parameters reflecting muscle damage, i.e., creatine kinase (CK) and myoglobin.
Fifteen healthy men, used to moderate physical activity, not including weightlifting, performed a 1-hour-long weight training program.
Five out of eight studied clinical chemistry parameters (AST, ALT, LD, CK, and myoglobin) increased significantly after exercise and remained elevated for at least 7 days postexercise. Bilirubin, GGT, and ALP remained within the normal range.
The liver function parameters, AST and ALT, were significantly increased for at least 7 days after the exercise. In addition, LD and, in particular, CK and myoglobin showed highly elevated levels. These findings highlight the importance of imposing restrictions on weightlifting prior to and during clinical studies to avoid making wrong assumptions about liver toxicity caused by study medications. Intensive muscular exercise, e.g., weightlifting, should also be considered a cause of asymptomatic elevations of liver function tests in daily clinical practice.
This is why GGT may be more accurate for men who actively do weight training.
Gamma Glutamyl Transpeptidase (GGT)
An increase in GGT might signify serious liver issues like cirrhosis or hepatitis. Regular monitoring of this enzyme through a liver panel test is essential for early detection and treatment of any underlying conditions affecting your liver's health.
A liver panel test can be a useful indicator of shifts in the amounts of enzymes and proteins within your body, enabling you to take steps if necessary. To ensure optimal health, it's important to be aware of the recommended frequency for liver panel tests
The Significance of Early Detection Through Testing
Regular monitoring with liver function tests is crucial for maintaining overall health since some symptoms may not appear until it's too late. Early detection allows doctors to recommend therapies or lifestyle changes that can help mitigate issues while giving the liver an opportunity to regenerate itself. In this section, we will discuss when and how often you should get tested.
When Should You Get Tested?
It's always better to do a liver function test sooner rather than later. Certain liver issues may not cause any indications, so you could be oblivious to their presence. It's recommended to do a liver test panel periodically when taking certain medications that might affect your liver, as well as if you see apparent symptoms of liver problems such as yellowing of the eyes.
How Often Should You Test?
- Routine Check-ups: If you don't have any known risk factors or pre-existing conditions related to your liver, getting tested every one or two years during routine check-ups is generally sufficient.
- Risk Factors: For those with risk factors such as obesity, diabetes, high blood pressure, a family history of liver disease, or excessive alcohol consumption; more frequent testing (every six months) is advisable.
- Taking Medications: If you're taking long-term medication that has potential side effects on the liver, regular monitoring (every three months) would be prudent in order to catch any adverse reactions early on.
Besides these general guidelines, it's essential to consult with your healthcare provider regarding personalized testing recommendations based on your unique health profile and circumstances. Remember, early detection is key to preventing liver damage and ensuring optimal liver function.
Once you have been tested and received the results, your doctor will help you interpret them. In some cases, and only if necessary, you might need to do additional tests, such as a hepatitis virus test. A biopsy might also be required to confirm a specific diagnosis before beginning treatment.
Early detection through testing is a critical factor in safeguarding your health, since it allows for the identification of any potential issues prior to them becoming more serious. With this knowledge, we can now look at additional tests based on the initial results to further assess the condition of your liver.

The frequency of testing depends on risk factors such as obesity, diabetes, high blood pressure, a family history of liver disease, or excessive alcohol consumption. It's important to consult with a healthcare provider for personalized testing recommendations based on individual circumstances.
Additional Tests Based on Initial Results
After receiving the results of your comprehensive liver panel test, it is crucial to consult with a healthcare professional for proper interpretation and guidance. In some cases, elevated levels of certain enzymes may warrant further examination through additional tests. These supplementary assessments can provide more specific diagnoses and help determine the most appropriate course of treatment for liver-related issues.
Hepatitis Virus Testing
If abnormal enzyme levels are detected during the initial liver panel test, hepatitis virus testing might be recommended by your doctor. Viral infections like hepatitis A, B, or C cause hepatitis, which is an inflammation of the liver. Left untreated, hepatitis virus infections can result in chronic liver disease and potentially life-threatening complications.
- Hepatitis A: Typically transmitted through contaminated food or water sources, vaccination is available for prevention.
- Hepatitis B: Transmitted via blood or bodily fluids; vaccination available for prevention.
- Hepatitis C: Primarily spread through contact with infected blood; no vaccine is currently available, but curative treatments exist.
In instances where further clarification is needed after initial test results and hepatitis virus testing have been conducted, a doctor may recommend undergoing a liver biopsy. This procedure involves removing a small sample of liver tissue using a needle, which will then be examined under a microscope to identify any abnormalities that could indicate conditions such as:
- Fatty liver disease: A buildup of fat in the liver cells, which can lead to inflammation and scarring.
- Cirrhosis: Severe scarring of the liver that impairs its ability to function properly.
- Hepatitis or other infections: Inflammation caused by viral, bacterial, or parasitic infections that damage the liver.
- Liver cancer: Malignant tumors originating from the liver tissue itself or spreading from another part of the body (metastatic).
Taking a proactive approach to your health through regular monitoring with liver panel tests is essential for early detection and intervention. By identifying potential issues before they become severe, you give yourself an opportunity to make lifestyle changes and seek appropriate treatments under professional guidance. Remember that knowledge is power when it comes to maintaining optimal health.
Subsequent assessments based on preliminary findings can furnish a more precise understanding of your liver condition, enabling an exacter prognosis. To make testing even easier, Discounted Labs offers convenient and affordable options for ordering lab tests online.
