What's this test for?

This test is ideal if you're experiencing unexplained fatigue, difficulty losing weight, digestive issues, or general health concerns that you can't pinpoint. It provides a comprehensive snapshot of your metabolic health, including how your body processes energy, how well your organs are functioning, and whether nutritional deficiencies might be affecting your well-being. Many people use this test as a thorough health check-up to identify hidden factors that could be impacting their energy, weight, and overall vitality.

How should I prepare for this test?

Fasting: 12 hours

You need to fast for 12 hours before your blood draw, which means no food or beverages except water during this time. Schedule your appointment in the morning since iron levels naturally decrease by 30% throughout the day. If you take medications that affect uric acid levels like diuretics, pyrazinamide, ethambutol, or nicotinic acid, discuss temporarily stopping them with your doctor before testing. Fasting ensures the most accurate results for your glucose, lipids, and iron levels.

What's included in this test?

Amylase Bilirubin, Direct GGT Iron, Total Magnesium Uric Acid

This comprehensive panel evaluates your metabolic function through glucose levels and lipid markers, which reveal how your body processes sugar and fat and your cardiovascular risk. It assesses liver and kidney health to ensure proper detoxification and waste removal, checks thyroid function to identify causes of fatigue and weight issues, and measures essential nutrients like iron and magnesium that affect energy production. Together with a complete blood count, these measurements provide a complete picture of factors affecting your metabolism, energy, and overall health.

What happens after I get my results?
You'll receive detailed doctor notes in simple language that explain what your metabolic markers mean for your energy levels, weight management, and organ health. These notes include personalized recommendations like dietary adjustments, lifestyle changes, supplement suggestions, or which specific markers need closer monitoring. You'll also get the standard lab report and can track your biomarkers over time using our trends feature to see how your health improves with dietary and lifestyle interventions.
Who should consider getting this test?
This test is valuable for anyone experiencing persistent fatigue, unexplained weight changes, or general concerns about their health and metabolism. It's especially useful for people wanting a comprehensive baseline health assessment, those with family histories of diabetes or heart disease, individuals starting a new diet or fitness program, or anyone who hasn't had thorough blood work in over a year. It's also helpful if you have multiple vague symptoms that don't point to one specific condition.
What symptoms indicate I may need this test?
Common symptoms include constant tiredness that doesn't improve with rest, difficulty losing or unexplained gaining weight, brain fog or poor concentration, frequent headaches, or digestive problems. You might also notice muscle weakness, changes in appetite, mood swings, feeling cold or hot frequently, or just a general sense that something is off with your health. These symptoms can indicate metabolic imbalances, nutritional deficiencies, thyroid issues, or organ dysfunction that this panel can identify.
How can I naturally support my metabolic health?
Start with balanced meals that include protein, healthy fats, and complex carbohydrates to stabilize blood sugar throughout the day. Regular physical activity, even just 30 minutes of walking daily, significantly improves metabolic function and energy levels. Prioritize 7-9 hours of quality sleep, stay well-hydrated, and manage stress through meditation or yoga. Eating nutrient-dense whole foods rich in vitamins and minerals naturally supports liver, kidney, and thyroid function.
What does high glucose mean?
High fasting glucose indicates your body isn't processing sugar efficiently, which can be an early warning sign of prediabetes or diabetes. Elevated glucose levels can cause fatigue, increased thirst, frequent urination, and difficulty concentrating. It's often related to diet, physical inactivity, excess weight, stress, or insulin resistance. Lifestyle changes like reducing refined carbohydrates, increasing exercise, and losing even 5-10% of body weight can significantly improve glucose levels.
What does high cholesterol indicate?
High cholesterol, particularly elevated LDL or total cholesterol, means excess fatty substances are circulating in your blood, which can build up in artery walls and increase heart disease risk. Many factors contribute including diet high in saturated fats, lack of exercise, genetics, and being overweight. The good news is that cholesterol often responds well to dietary changes like increasing fiber, choosing healthier fats, exercising regularly, and maintaining a healthy weight.
How often should I retest my metabolic markers?
If your results are normal and you're healthy, retesting every 1-2 years is typically sufficient for preventive monitoring. If you have borderline or abnormal results, your doctor may recommend retesting in 3-6 months to see if lifestyle changes are working. If you're managing a condition like prediabetes, high cholesterol, or thyroid issues, you may need testing every 3-6 months initially, then every 6-12 months once stable. More frequent testing helps track the effectiveness of diet, exercise, or medication changes.

What this means

Your fasting glucose is slightly elevated above the normal range, which may indicate early insulin resistance or prediabetes. This can contribute to fatigue, increased thirst, difficulty concentrating, and challenges with weight management. Addressing this now through lifestyle changes can help prevent progression to type 2 diabetes.

* 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.
