Not Sure Which Health Test to Start With?

You do not need every test. The best first test is usually the one that answers your biggest question right now. Start with your main concern below, then choose the test that gives you the most useful data first.

Important Note: NuGeneLabs plain-language results summary and practical roadmap are included with all functional health tests and blood panels.


If You Have Bloating, Gas, Constipation, Diarrhea, or Food Reactions

Start with gut testing. For those who are starting detoxing and detox feels hard, energy is low, or supplements haven’t helped, starting with metabolic or gut-related testing is often the smartest move.

Best starting points:

  • GI-MAP Stool Test - DNA-based stool analysis for bacteria, parasites, fungi, H. pylori, opportunistic organisms, and intestinal health markers.
  • SIBO Breath Test - when bloating, gas, constipation, diarrhea, or food-triggered symptoms may be related to small-intestine gas patterns.
  • GI Effects Gut Health Stool Test - when you want a broader stool test for digestion, absorption, inflammation, immune activity, microbiome balance, yeast, bacteria, and parasites.
  • IgG Food Explorer™ - Measures IgG antibodies to a selection of foods. Food-specific IgG results do not establish a food allergy or sensitivity and should not be used alone to eliminate foods. Discuss persistent food-related symptoms with a qualified healthcare provider.
  • IgE Allergy Explorer™ - Best when you want to review IgE sensitization patterns related to food or environmental allergens.


If You Feel Tired, Foggy, Inflamed, or “Off” Despite Supplements

Start with nutrient, metabolomics, or cellular energy testing.

Best starting points:


If You Want Hormone, Stress, Sleep, or Menopause Insight

Start with hormone or cortisol rhythm testing.

Best starting points:

  • DUTCH Complete Hormone Test - Best for sex hormones, estrogen metabolites, progesterone metabolites, androgen patterns, cortisol rhythm, cortisol metabolites, melatonin, and organic acid markers.
  • ZRT Adrenal Stress Profile - Best for a simpler at-home saliva cortisol rhythm test with four-point cortisol and morning DHEA-S.
  • Blood Panels - Best when thyroid markers, inflammation, blood sugar, iron, vitamin D, or standard blood chemistry should be reviewed first.


If Weight Loss Stalls or You Need Metabolic Health, or GLP-1 Response Insight

GX Sciences ReGENErate DNA Test - Best when you want a nutrigenomic cheek swab test for weight loss, metabolic health, diet response, GLP-1 response, appetite patterns, nutrient needs, and personalized nutrition planning.


If You Want Longevity, Biological Age, or Genetic Insight

Start with biological age, DNA, or cellular health testing.

Best starting points:


If You Want Detox, Heavy Metal, or Environmental Exposure Insight

Start with toxic burden and detox pathway testing.

Best starting points:

If you have already tried supplements without clear results, testing can help narrow the plan before adding more products.

Frequently Asked Questions

How are functional health tests different from blood tests ordered during a regular checkup?

Routine checkup panels usually use blood to evaluate broad clinical markers such as blood counts, glucose, cholesterol, liver and kidney function, and sometimes thyroid or nutrient levels. They are often the appropriate starting point for general screening and medical evaluation.

Functional health tests are typically more targeted. Depending on the question, they may use stool, urine, saliva, breath, cheek swabs, blood spots, or a conventional blood draw to examine areas such as the gut microbiome, digestive function, hormone metabolites, organic acids, nutrient metabolism, toxic metals, or genetic patterns.

Functional tests are not automatically better than routine bloodwork, and they do not replace medical testing or care. They provide a different layer of information when someone wants to explore a more specific health question. NuGeneLabs translates the laboratory report into plain language and provides test-based supplement and lifestyle recommendations. Diagnosis and treatment should come from a licensed healthcare provider.

Which health test should I start with?

Start with the symptom or goal that affects you most. Digestive symptoms usually point toward gut or SIBO testing. Fatigue and brain fog often point toward nutrient, organic acid, or metabolic testing. Hormone, sleep, or stress concerns may fit DUTCH or cortisol testing. Longevity goals may fit biological age, telomere, NAD, or DNA testing.

Will these tests tell me which supplements to take?

The tests do not automatically prescribe supplements. NuGeneLabs reviews the results and provides supplement and lifestyle recommendations based on the findings, so your plan is more targeted than guessing.

Are these tests done at home?

Most tests use at-home collection, such as stool, urine, saliva, blood spot, cheek swab, or breath collection. Some panels may require a blood draw or lab visit depending on the test.

Do these tests diagnose medical conditions?

No. These tests are for wellness education and functional insight. They are not a replacement for diagnosis, treatment, or care from a licensed healthcare provider.
