Clinicians use the GGT-to-Platelet Ratio (GPR) to estimate liver scarring without a biopsy. It can help decide who may benefit from imaging or elastography and closer follow-up, especially in chronic viral hepatitis or fatty liver. You can test this marker with Aniva across Germany and Finland.

High: May point to greater liver stress or scarring risk; consider reviewing alcohol and medicines, and follow up with a liver panel, ultrasound, or elastography.
Low: Suggests lower likelihood of advanced scarring; keep healthy habits and monitor if you have ongoing risks. Trends over time and context with other tests give the clearest picture.
Common factors that can affect GPR include recent alcohol use, enzyme-inducing medicines (for example, anticonvulsants), cholestasis or biliary disease, acute illness or infection, dehydration, and strenuous exercise. Platelet counts can vary with infection, inflammation, iron deficiency, pregnancy, or lab artifacts such as EDTA-related clumping. Time of day has small effects; fasting is not required.
Special situations: confirm or adjust in pregnancy, after heavy alcohol use, during chemotherapy, or when platelet disorders are known or suspected.
What does a high GPR mean? It suggests more liver stress or a higher chance of scarring. Your clinician may confirm with imaging, elastography, or other blood tests.
Do I need to fast for this test? No. Fasting is not required for GPR, though avoiding alcohol before testing can help reduce short-term spikes in GGT.
What can affect my result? Alcohol, certain medicines, acute infections, dehydration, and heavy exercise can shift GGT or platelets. Always share current medicines and supplements.
How often should I test GPR? It depends on your risk and care plan. People with chronic liver risks may recheck periodically to track trends; ask your clinician.
How long do results take? Most labs report within 1–3 days. Turnaround can vary based on location and workload.
What should I discuss with my clinician? Talk about alcohol use, medicines, viral hepatitis status, prior imaging, and any symptoms. Ask whether additional tests are needed for a clearer picture.
