Liver Function Test

Fasting requirements depend on which specific tests are ordered. For a basic liver function panel, fasting is typically not required. However, if your test is part of a comprehensive metabolic panel or includes lipid testing, you may need to fast for 8-12 hours before your blood draw. Our medical providers will give you specific instructions based on your testing needs. You can usually drink water during the fasting period.

Liver function tests measure several enzymes and proteins that indicate how well your liver is working. Key measurements include ALT and AST (enzymes released when liver cells are damaged), alkaline phosphatase (enzyme related to bile ducts), bilirubin (waste product processed by the liver), and albumin (protein made by the liver). According to the National Institutes of Health, these markers together provide a comprehensive picture of liver health and can detect inflammation, damage, or disease.

Most liver function test results are available within 24-48 hours after your blood draw. We process samples through certified laboratories that provide accurate, reliable results. Once results are available, our medical providers will contact you to discuss findings and any necessary follow-up. If results show significant abnormalities requiring immediate attention, we'll reach out to you promptly.

Elevated liver enzymes can result from many conditions including viral hepatitis, fatty liver disease, alcohol use, certain medications, autoimmune disorders, or other liver diseases. According to Mayo Clinic research, even some over-the-counter medications and supplements can affect liver enzyme levels. Temporary elevations can also occur from strenuous exercise or muscle injury. Our medical providers will help determine the cause of any abnormalities and recommend appropriate next steps.

If your liver function tests show abnormalities, our medical providers will discuss the findings with you and explain what they mean. Depending on the severity and pattern of abnormalities, recommendations may include lifestyle modifications, avoiding certain medications or alcohol, repeat testing, additional diagnostic studies like ultrasound, or referral to a gastroenterologist or hepatologist. Many liver conditions are highly treatable when detected early, so follow-up is important.

Yes, many medications can affect liver enzyme levels, including common drugs like statins, antibiotics, pain relievers, and even some herbal supplements. According to the FDA, medication-induced liver injury is a leading cause of elevated liver enzymes. Always bring a complete list of your current medications, including over-the-counter drugs and supplements, to your visit. Our medical providers will review your medications when interpreting your results and may recommend adjustments if needed.
