What's this test for?

This test is ideal if you're experiencing chronic fatigue, low energy, unexplained health issues, or just want a comprehensive picture of your overall wellness. It evaluates your metabolic function, hormone balance, blood health, nutritional status, inflammation levels, and cardiovascular markers to identify underlying causes of symptoms. Many people use this panel when they feel something is off but can't pinpoint what, or when they want to proactively optimize their health and prevent future problems.

How should I prepare for this test?

Fasting: 12-14 hours
No biotin: 72 hours

You should fast for 12-14 hours before your blood draw, consuming only water during this time. If you take high-dose biotin supplements (more than 5 mg per day), stop taking them at least 72 hours before testing, as they can interfere with some results. If you're on high biotin therapy for medical reasons, wait at least eight hours after your last dose before the blood draw.

What's included in this test?

Hs CRP Dhea Sulfate Ferritin Hemoglobin A1C Insulin Iron, Total Progesterone Sed Rate By Modified Westergren Dihydrotestosterone, LC/MS/Ms

This comprehensive panel evaluates your metabolic health through glucose and HbA1c to assess blood sugar control, a complete lipid panel for cardiovascular risk, and liver and kidney function markers. It checks nutritional status with Vitamin D, iron, and ferritin levels that directly impact energy and immunity. Hormone measurements including insulin, IGF-1, DHEA-S, progesterone, and DHT provide insights into growth, stress response, and hormonal balance, while a complete blood count and inflammatory markers help identify hidden health issues affecting your vitality and wellness.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your metabolic, hormonal, and nutritional markers mean for your energy, wellness, and overall health. These notes include personalized recommendations like dietary changes, supplement suggestions, lifestyle modifications, or whether you should follow up with a specialist for specific concerns. You'll also get the standard lab report and can track all your biomarkers over time using our trends feature to monitor improvements as you make health changes.
When will I get my results?
Your results will be ready in approximately 7 business days after your sample is collected. If any confirmatory testing is needed for specific biomarkers, the turnaround time may be extended slightly, but you'll be notified of any delays.
Who should consider getting this test?
This test is perfect for anyone experiencing persistent fatigue, difficulty losing weight, mood changes, or general concerns about their health. It's also valuable for health-conscious individuals who want a baseline assessment of their metabolic and hormonal function, people with family histories of diabetes or heart disease, or anyone looking to optimize their wellness and catch potential issues early.
What symptoms indicate I may need this test?
Common symptoms include constant tiredness despite adequate sleep, unexplained weight changes, difficulty concentrating or brain fog, mood swings or feeling down, and reduced stamina or motivation. You might also experience muscle weakness, frequent illnesses, slow recovery from exercise, irregular energy levels throughout the day, or just a general feeling that something is off with your health.
How can I naturally support my metabolic health?
Focus on eating whole foods with balanced protein, healthy fats, and complex carbohydrates while limiting processed foods and added sugars. Regular exercise combining both cardio and strength training helps regulate insulin and metabolism. Prioritize 7-9 hours of quality sleep, manage stress through meditation or yoga, stay hydrated, and consider getting morning sunlight exposure to support your circadian rhythm and vitamin D levels.
What is HbA1c and why does it matter?
HbA1c (Hemoglobin A1c) measures your average blood sugar levels over the past 2-3 months, giving a long-term picture of how well your body manages glucose. Unlike a single fasting glucose test, HbA1c shows patterns over time and is used to diagnose prediabetes and diabetes. Keeping it in a healthy range helps prevent fatigue, weight gain, and serious complications like heart disease and nerve damage.
What does high insulin mean?
High fasting insulin often indicates insulin resistance, where your cells don't respond well to insulin, so your body produces more to manage blood sugar. This can lead to weight gain (especially around the belly), increased hunger, fatigue after meals, and is a warning sign for prediabetes or metabolic syndrome. Managing it through diet, exercise, and weight loss can help prevent type 2 diabetes and improve energy levels.
How often should I retest this panel?
If your results are normal and you're feeling well, retesting every 6-12 months is reasonable for ongoing wellness monitoring and catching changes early. If you have abnormal results or are making lifestyle changes, consider retesting in 3-6 months to track improvements. People managing chronic conditions or optimizing hormones may benefit from more frequent testing every 3-4 months under their healthcare provider's guidance.

What this means

Your Vitamin D level is below the optimal range, which is common but can contribute to fatigue, weakened immunity, mood issues, and poor bone health. Many people are deficient in Vitamin D, especially during winter months or with limited sun exposure, but this is easily correctable with lifestyle changes and supplementation.

* 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.
