Begin with your health question
What would you like
to understand?
A useful test starts with a focused question. Choose an area to begin, or let the questionnaire help you organise a broader concern.
Nutrition & cofactors
Explore a question about nutrient intake, absorption, supplementation or a recurring symptom pattern.
Digestion & gut health
Consider a focused stool or metabolic route in the context of meals, bowel patterns and previous assessment.
Hormones & life stage
Bring life stage, medication and collection timing into the choice of a hormone-related testing route.
Looking at energy, sleep, recovery or a specific exposure?

From a question to useful information
A clear process.
A more informed decision.
Choose your focus
Start with one main question: energy, digestion, nutrients, sleep, hormones or another concern.
Answer a few questions
See only relevant questions, with simple choices and a quick suitability check. There is no need to rate a long symptom list.
See your WHL testing option
Every completed guide shows a WHL test option, with clinical advice where relevant. Save your summary or ask WHL for help confirming the next step.
Understanding your results
More context.
Better questions to discuss.
The questionnaire gives you a testing route, not a laboratory result. Laboratory analysis measures the markers included in the panel you order.
- Check which markers and specimen types are included.
- Read measured findings alongside symptoms, medicines and previous investigations.
- Discuss interpretation and any treatment decisions with a qualified healthcare professional.
A finding outside a reference interval does not, by itself, explain a symptom or establish a diagnosis.
Prefer a convenient home blood test?
Meet WHL HomeLab.
Explore our dedicated at-home blood-test panels. Each HomeLab blood-test panel includes a Tasso collection device, and you can order more than one panel in the same checkout.
HomeLab is a separate range. Specialist functional panels may need different specimens, approved venous collection or special handling. If combining panels, confirm sample and device requirements with WHL.
Before you start
A few useful
answers.
Understand what the guide can help with, how collection works, and what happens after you receive your result.
Will the questionnaire tell me what condition I have?
No. Every completed guide shows a WHL test option linked to the selected area. Where needed, clinical advice appears alongside it. The option does not establish a diagnosis or mean testing is medically necessary. Urgent symptoms always require medical attention first.
Do I need to give my name or email to see my result?
No. Your questionnaire result appears immediately without your name or email. This replacement guide processes answers in your browser and does not send them to WHL automatically. You can download a summary and choose whether to share it.
Can I order several panels together?
Yes, you can select more than one panel in the WHL shop. Check for overlapping measurements and confirm the required specimens, collection kits and shipping arrangements. This short guide shows one possible starting panel; WHL can help if you have several testing questions.
Does every panel on this page include a Tasso device?
The dedicated HomeLab at-home blood-test panels include a Tasso collection device. Other functional panels shown here may use urine, stool, saliva or specialist blood specimens and have different collection requirements. Check the individual product details before ordering.
Can I collect all the samples at home?
Many urine, stool and saliva tests use home collection. Some blood tests require approved venous collection, stabilisation, specific tubes or controlled transport. A home-collection preference does not make every analysis suitable for a Tasso sample; WHL can confirm the plan.
What if I take medication or supplements?
Include the relevant context in your answers and read the preparation instructions for the panel. Some medicines, hormone treatment, corticosteroids, recent antibiotics or supplements can affect selection, timing or interpretation. Do not stop prescribed treatment without your prescriber’s advice.
How soon will I receive results?
Your questionnaire guidance appears immediately after you finish. Laboratory turnaround varies by panel and starts at the point specified for that service. Check the current product page or contact WHL for collection, transport and reporting details.
Will I still see a WHL test if I need advice first?
Yes. The WHL option remains visible with advice about clinical assessment, preparation, medication or collection timing where relevant. An option above your chosen budget is clearly marked. For urgent symptoms, medical care comes first and testing information is available for later clinical discussion.
