What's this test for?

This test is ideal if you're experiencing chronic fatigue, unexplained weakness, or general concerns about your overall health. It helps identify issues with your blood sugar levels, kidney function, liver health, and electrolyte balance that may be causing your symptoms. Many people use this test as a comprehensive health checkup to catch potential problems early or to monitor existing conditions like diabetes or kidney disease.

How should I prepare for this test?

Fasting: 12 hours

You should fast for 12 hours before your blood draw. This means no food or drinks except water during this time. Fasting is important because it ensures accurate glucose and other metabolic measurements. Schedule your test for the morning so you can fast overnight, and remember to stay well-hydrated with water.

What's included in this test?

ALT AST Albumin Albumin/Globulin Ratio Alkaline Phosphatase Bilirubin, Total Bun/Creatinine Ratio Calcium Carbon Dioxide Chloride Creatinine Globulin Glucose Potassium Protein, Total Sodium Urea Nitrogen (Bun) eGFR

This comprehensive panel evaluates your blood sugar control through glucose measurements, which helps identify diabetes or prediabetes risk. It assesses kidney function through creatinine, BUN, and eGFR to catch early signs of kidney disease, checks liver health with enzyme tests (ALT, AST, alkaline phosphatase) that can reveal liver damage or inflammation, and measures essential electrolytes and minerals (sodium, potassium, calcium, chloride) that affect everything from heart rhythm to muscle function. Together, these measurements provide a complete picture of your metabolic health and help identify underlying conditions causing fatigue or other symptoms.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your metabolic markers, kidney function, liver enzymes, and blood sugar levels mean for your overall health. These notes include personalized recommendations like dietary changes, hydration strategies, supplement suggestions, or when to follow up with your primary care doctor. You'll also get the standard lab report and can track your metabolic health over time using our trends feature to see how lifestyle changes are impacting your numbers.
Who should consider getting this test?
This test is important for anyone experiencing unexplained fatigue, excessive thirst, frequent urination, or general weakness. It's also valuable for people with risk factors for diabetes, kidney disease, or liver problems, those with high blood pressure or cardiovascular concerns, and anyone wanting a comprehensive baseline health assessment. If you have a family history of diabetes or kidney disease, regular testing helps catch issues early.
What symptoms indicate I may need this test?
Common symptoms include persistent fatigue or weakness, unexplained weight changes, increased thirst or frequent urination, swelling in your hands or feet, changes in urine color or output, nausea or loss of appetite, and yellowing of skin or eyes. You may also need this test if you're experiencing muscle cramps, irregular heartbeat, confusion, or general feelings of being unwell without an obvious cause.
How can I naturally support my metabolic health?
Start by maintaining a balanced diet rich in whole foods, vegetables, lean proteins, and healthy fats while limiting processed foods and added sugars. Stay well-hydrated by drinking plenty of water throughout the day, as proper hydration supports kidney function and electrolyte balance. Regular exercise, maintaining a healthy weight, limiting alcohol consumption, and getting 7-8 hours of quality sleep each night all help optimize your metabolic health and organ function.
What does high glucose mean?
High glucose levels indicate your body is having trouble regulating blood sugar, which may signal prediabetes or diabetes. This can happen due to insulin resistance, poor diet, lack of exercise, stress, or pancreatic issues. Consistently elevated glucose increases your risk for heart disease, nerve damage, kidney problems, and vision issues over time, so it's important to address through lifestyle changes or medical treatment.
What does low eGFR mean?
Low eGFR (estimated glomerular filtration rate) means your kidneys aren't filtering waste from your blood as efficiently as they should. This can indicate chronic kidney disease, dehydration, medication effects, or other kidney problems. The lower the eGFR, the more advanced the kidney dysfunction, so it's important to work with your doctor to identify the cause and prevent further damage through diet, hydration, blood pressure control, and possibly medication adjustments.
How often should I retest my metabolic panel?
If your results are normal and you're healthy, retesting every 1-2 years is typically sufficient for general wellness monitoring. If you have diabetes, prediabetes, kidney disease, or liver problems, your doctor will likely recommend testing every 3-6 months to monitor your condition and treatment effectiveness. After making significant lifestyle changes or starting new medications that affect metabolism, retesting in 8-12 weeks helps track your progress.

What this means

Your eGFR is slightly below the optimal range, indicating your kidneys may not be filtering waste as efficiently as they should. This could be an early sign of reduced kidney function that warrants closer monitoring and lifestyle adjustments to prevent further decline.

* 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.
