What's this test for?

This test is ideal if you're experiencing unexplained fatigue, changes in urination, swelling in your legs or ankles, or digestive issues. It provides a comprehensive evaluation of how well your kidneys and liver are functioning, helping identify potential problems before they become serious. Many people use this test when they have risk factors like high blood pressure, diabetes, alcohol use, or a family history of kidney or liver disease.

How should I prepare for this test?

Fasting: 12-14 hours

You should fast for 12-14 hours before your test, which means no food or drinks except water. Avoid smoking before your appointment as it can affect ammonia levels, and don't clench your fist during the blood draw. Discuss with your doctor about temporarily stopping certain medications like diuretics or gout medications that may affect uric acid levels. Results typically take about 5 business days, though some specialized tests may take longer if confirmation is needed.

What's included in this test?

Lactic Acid, Plasma Ammonia (P) Alpha Fetoprotein, Tumor Marker Ceruloplasmin Copper GGT LD Phosphate (As Phosphorus) Beta 2 Microglobulin, Serum Uric Acid

This comprehensive panel evaluates kidney function through creatinine, BUN, eGFR, and cystatin-C to detect early signs of kidney disease, plus a complete urinalysis to check for protein, blood, or infection. It assesses liver health with enzymes like ALT, AST, alkaline phosphatase, GGT, bilirubin, and specialized markers like alpha-fetoprotein and ammonia that reveal inflammation or damage. The panel also includes metabolic markers, lipid levels, electrolytes, and minerals that affect both organ systems, providing a complete picture of your kidney and liver health and how they're impacting your energy and wellness.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your kidney and liver markers mean for your overall health and energy levels. These notes include personalized recommendations like dietary changes, hydration strategies, supplement suggestions, or whether you should follow up with a specialist. You'll also get the standard lab report and can track your organ function over time using our trends feature to monitor improvements or catch changes early.
When will I get my results?
Your results will typically be ready within 5 business days after your blood sample is collected. Some specialized markers in this comprehensive panel may require confirmation testing, which could extend the turnaround time by a few additional days. You'll receive an email notification as soon as your results are available in your secure online account.
Who should consider getting this test?
This test is important for people with risk factors like diabetes, high blood pressure, obesity, or a history of heavy alcohol use. It's also valuable if you have a family history of kidney or liver disease, take medications that affect these organs, or have symptoms like persistent fatigue, dark urine, yellowing skin, or unexplained swelling. Anyone concerned about their organ health or wanting a baseline measurement for preventive care should consider this comprehensive panel.
What symptoms indicate I may need this test?
Common symptoms include persistent fatigue, difficulty concentrating, changes in urination frequency or color, swelling in your ankles or legs, and unexplained weight changes. You might also notice digestive issues, nausea, loss of appetite, itchy skin, yellowing of the eyes or skin, or abdominal discomfort. Since kidney and liver problems often develop silently, regular testing is important even without obvious symptoms, especially if you have risk factors.
How can I naturally support my kidney and liver health?
Stay well-hydrated by drinking plenty of water throughout the day, and eat a balanced diet rich in fruits, vegetables, whole grains, and lean proteins while limiting processed foods and excess salt. Limit alcohol consumption and avoid unnecessary medications or supplements that stress these organs. Regular exercise, maintaining a healthy weight, and managing conditions like diabetes and high blood pressure are crucial for protecting both kidney and liver function.
What does high creatinine mean?
High creatinine levels suggest your kidneys may not be filtering waste from your blood as efficiently as they should. This can be caused by dehydration, kidney disease, high protein intake, intense exercise, or certain medications. Elevated creatinine is an important early warning sign that your kidney function needs attention and possibly further evaluation.
How often should I retest my kidney and liver function?
If you have risk factors like diabetes or high blood pressure, annual testing is recommended to catch problems early. If you're on medications that affect these organs or have been diagnosed with kidney or liver issues, your doctor may recommend testing every 3-6 months to monitor your condition. For general preventive care without risk factors, testing every 1-2 years provides a good baseline to track changes over time.

What this means

Your eGFR is slightly below the optimal range, which may indicate your kidneys are not filtering waste as efficiently as they should. While this is considered mildly reduced kidney function, it's important to monitor and take steps to protect your kidney health before it progresses further.

* 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.
