What's this test for?

This test is ideal if you're experiencing unexplained fatigue, digestive issues, or want to check for liver stress related to alcohol consumption or medication use. It helps identify early liver damage, bile duct problems, or general liver dysfunction that may be affecting your energy and overall health. Many people use this test to monitor liver health as part of wellness optimization or to detect hidden damage before symptoms become severe.

How should I prepare for this test?

No fasting is needed for this test, making it convenient and easy to schedule. You can eat and drink normally before your blood draw. Just visit your chosen lab location during their operating hours for a quick blood sample collection.

What's included in this test?

GGT

This test measures Gamma Glutamyl Transpeptidase (GGT), a sensitive enzyme marker that reveals liver and bile duct health. Elevated GGT is one of the earliest indicators of liver stress from alcohol, medications, or fatty liver disease, often appearing before other liver markers become abnormal. It's particularly useful for distinguishing liver problems from bone-related issues when other tests like alkaline phosphatase are elevated, giving you clear insight into whether lifestyle factors are affecting your liver function.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your GGT level means for your liver health and overall wellness. These notes include personalized recommendations like dietary changes, alcohol reduction strategies, supplement suggestions, or whether you should follow up with a specialist. You'll also get the standard lab report and can track your GGT levels over time using our trends feature to see how your lifestyle changes are improving your liver health.
Who should consider getting this test?
This test is valuable for anyone who regularly consumes alcohol, takes medications that may affect the liver, or has risk factors for fatty liver disease like obesity or metabolic syndrome. It's also important for people experiencing unexplained fatigue, digestive discomfort, or those wanting to monitor liver health as part of preventive wellness. If you have a family history of liver disease or want to assess the impact of your lifestyle choices on liver function, this test provides early detection of potential issues.
What symptoms indicate I may need this test?
Common symptoms that may indicate elevated GGT include persistent fatigue, loss of appetite, nausea, abdominal discomfort (especially in the upper right side), dark urine, or yellowing of the skin or eyes. You might also consider this test if you notice unexplained itching, digestive issues, or simply feel like your energy levels have declined without clear explanation, especially if you consume alcohol regularly or take certain medications.
How can I naturally support my liver health?
Supporting liver health starts with limiting alcohol consumption and staying well-hydrated throughout the day. Eating a balanced diet rich in vegetables, fruits, lean proteins, and healthy fats while reducing processed foods and excess sugar helps reduce liver stress. Regular exercise, maintaining a healthy weight, and getting adequate sleep all support optimal liver function and can help lower elevated GGT levels over time.
What is GGT and why does it matter?
GGT (Gamma Glutamyl Transpeptidase) is an enzyme found primarily in the liver and bile ducts that helps process toxins and medications. It's one of the most sensitive markers for detecting liver stress and damage, often rising before other liver enzymes become abnormal. Elevated GGT can indicate various liver conditions including fatty liver disease, alcohol-related damage, bile duct problems, or reactions to medications, making it a valuable early warning system for liver health.
What does high GGT mean?
High GGT levels indicate stress or damage to the liver and bile ducts. This elevation is commonly seen with regular alcohol consumption, fatty liver disease, bile duct obstruction, or medication side effects. It can also be elevated with metabolic syndrome, diabetes, or chronic inflammation. While elevated GGT doesn't pinpoint a specific disease, it signals that your liver is under stress and may benefit from lifestyle modifications or further evaluation.
How often should I retest my GGT levels?
If your GGT is elevated and you're making lifestyle changes like reducing alcohol or losing weight, retesting every 3-6 months helps track your progress. For monitoring ongoing liver conditions or medication effects, your doctor may recommend testing every 6-12 months. If your initial GGT is normal but you have risk factors or symptoms, annual testing can help catch changes early before they become significant problems.

What this means

Your GGT level is elevated above the optimal range, indicating some stress on your liver or bile ducts. This elevation is often seen with regular alcohol consumption, fatty liver, certain medications, or metabolic factors. While this doesn't necessarily mean serious disease, it suggests your liver would benefit from supportive lifestyle changes.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
