What's this test for?

This test is ideal if you're experiencing unexplained weight loss without trying to lose weight. It helps identify potential causes like thyroid problems, nutritional deficiencies, hormonal imbalances, diabetes, or digestive issues that could be affecting your metabolism and nutrient absorption. Many people use this test when they've noticed significant weight loss that concerns them and want to understand what's happening in their body.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your results mean for your weight, metabolism, and overall health. These notes include personalized recommendations like dietary changes, supplement suggestions, or whether you should follow up with a specialist. You'll also get the standard lab report and can track your biomarkers over time using our trends feature to see how your interventions are working.

What's included in this test?

This panel measures Insulin, Chloride, Potassium, Sodium, BUN/Creatinine Ratio, ALT, AST, Alkaline Phosphatase, Bilirubin, Albumin, Globulin, Protein, Calcium, Carbon Dioxide, Creatinine, Urea Nitrogen, Glucose, eGFR, Cholesterol ratios, LDL, Triglycerides, HDL, Ferritin, FSH, LH, Free T4, T4, T3 Uptake, TSH, Estradiol, Hemoglobin A1C, Cortisol, Vitamin D (D2, D3, Total), ANA Screen, Complete Blood Count with Differential, and High-Sensitivity CRP. This comprehensive panel evaluates thyroid function to identify metabolic causes of weight loss, checks blood sugar and insulin levels to assess diabetes risk, and measures nutritional markers like iron, vitamin D, and protein levels that affect weight. It also includes hormone testing (FSH, LH, estradiol, testosterone, cortisol) to detect hormonal imbalances, a complete blood count to check for anemia or infections, and metabolic panels to assess liver, kidney, and overall organ function. Together, these measurements provide a complete picture of factors that could be causing unexpected weight loss.

How should I prepare for this test?

You should fast for 12-14 hours before your blood draw, which means no food or beverages except water. If you use testosterone cream, avoid applying it to your inner elbow area for 24 hours before testing. If you take high-dose biotin supplements (over 5 mg/day), wait at least 8 hours after your last dose before testing. Results typically take about 10 business days.

When will I get my results?

Your results will be available in approximately 10 business days. If any tests require confirmation testing, the turnaround time may be slightly extended. You'll be notified as soon as your results are ready to view.

Who should consider getting this test?

This test is important for anyone experiencing unintentional weight loss of 5% or more of body weight over 6-12 months. It's especially relevant if you're also experiencing fatigue, changes in appetite, digestive issues, or other unexplained symptoms. People with a family history of thyroid disease, diabetes, or autoimmune conditions should also consider this comprehensive screening.

What symptoms indicate I may need this test?

Key symptoms include losing weight without trying, decreased appetite or feeling full quickly, persistent fatigue or weakness, changes in bowel habits, and feeling anxious or jittery. You might also notice hair loss, feeling cold or hot all the time, mood changes, irregular periods, or increased thirst. If you're experiencing unexplained weight loss along with any of these symptoms, this test can help identify the underlying cause.

How can I naturally support healthy weight maintenance?

Focus on eating nutrient-dense foods with adequate protein, healthy fats, and complex carbohydrates to support healthy weight. Manage stress through meditation, yoga, or deep breathing exercises, as chronic stress affects metabolism and hormone balance. Prioritize 7-9 hours of quality sleep each night, stay hydrated, and include strength training to maintain muscle mass. Avoid skipping meals and consider eating smaller, more frequent meals if you have a decreased appetite.

What could cause unexplained weight loss?

Common causes include an overactive thyroid (hyperthyroidism) that speeds up metabolism, diabetes that affects how your body uses glucose, nutritional deficiencies that prevent proper nutrient absorption, and chronic stress that elevates cortisol levels. Other possibilities include digestive disorders like celiac disease or inflammatory bowel disease, hormonal imbalances, certain medications, depression or anxiety, and in some cases autoimmune conditions. This comprehensive test helps identify which of these factors may be contributing.

How often should I retest if I have unexplained weight loss?

If your initial results show abnormalities, your doctor will likely recommend retesting in 6-12 weeks after starting treatment or making lifestyle changes. If results are normal but weight loss continues, retesting in 3-6 months can help identify trends or changes. Once you've identified the cause and stabilized your weight, annual monitoring is typically sufficient for preventive health.

What should I do if my results are abnormal?

Start by reviewing the doctor notes included with your results for personalized recommendations specific to your abnormal markers. Many issues can be improved with dietary changes, stress management, sleep optimization, and targeted supplements. However, significant abnormalities in thyroid function, blood sugar, or hormone levels should be discussed with your primary care doctor or an endocrinologist who can provide proper treatment and monitoring.
