One simple order.

You can order more than one panel at once. Add each panel to your cart and complete one order. Every panel includes its Tasso+ device and collection materials. Follow the instructions supplied for each panel; collection and return requirements may differ.

Your results, with context

Know what is measured.
Understand what comes next.

Your digital laboratory report brings the results from your selected panel together, with measurement units and laboratory reference intervals. It gives you a clear starting point for a conversation with your healthcare professional.

The value lies in the pattern: related markers can help distinguish nutrient status, hormone regulation and other physiological processes. Your symptoms, history and medication remain part of the interpretation.

Your collection kit

Everything starts with the included Tasso+.

Tasso+ collects a small liquid blood sample from your upper arm into an attached tube. There is no finger-prick collection. Close and pack the tube, then return it using your panel’s instructions.

This is laboratory testing with home collection. Your report provides measured values, units and relevant reference intervals for interpretation.

Included with every panel

  • 01The required Tasso+ collection device
  • 02Compatible sample tube and collection materials
  • 03Panel-specific preparation and collection instructions
  • 04Laboratory analysis and a digital report

We recommend filling each supplied collection tube to the marked fill line, following your kit instructions, so we have enough blood to perform the requested analyses. If we receive an underfilled tube, we will refund the analysis fee. Shipping charges and the cost of the Tasso device are excluded from the refund.

Your questions, answered

Frequently asked questions.

What is included, how to combine panels and what to expect from collection to results.

Is the Tasso+ device included in every panel?

Yes. Every HomeLab panel price includes the required Tasso+ upper-arm blood-collection device, compatible sample tube and collection materials, laboratory analysis and a digital report. Handling and shipping of €15.95 is added at checkout.

Can I order more than one panel at the same time?

Yes. Add each panel you would like to the same shopping cart and complete one order. Every panel includes its Tasso+ device and collection materials. Review the preparation requirements for each panel before collection; different panels may require different collection times or return conditions.

Can all my panels be collected with one device?

Do not assume that one device or one tube is suitable for every panel. The required sample type, volume and handling depend on the tests selected. Use the devices and tubes supplied and follow the collection plan and instructions provided by WHL. Contact the laboratory before collecting if you are unsure.

Is Tasso+ a finger-prick test?

No. Tasso+ attaches to the upper arm and collects a small liquid blood sample into an attached tube. Your sample is returned to the laboratory for analysis. It is not an instant home self-test.

What is included in the displayed price?

The listed panel price covers the included Tasso+ collection device and materials, the analyses listed for that panel and your digital laboratory report. Handling and shipping of €15.95 is added at checkout. Check the individual product page for any specialist transport requirements.

Do I need to fast or collect at a particular time?

Preparation depends on the panel. Some tests require morning fasting collection; male hormone testing and cycle-related panels have specific timing requirements. Other panels may require light protection, refrigeration or frozen return. Follow the instructions on the product page and inside each kit.

Should I stop medication or supplements before testing?

Follow the preparation instructions for your selected panel and tell your healthcare professional about relevant medicines and supplements. Do not stop or change prescribed medication without the advice of the clinician who prescribed it.

How do I collect enough blood?

Read the supplied instructions before starting. Allow collection to continue until the tube reaches the indicated fill level, within the time specified in the device instructions. Removing the device too early can leave insufficient sample. The step-by-step collection guide provides additional help.

How do I return my sample?

Use the supplied tube and protective packaging and follow the return instructions for each panel. Check collection and courier timing before starting. Temperature requirements differ: some samples need refrigerated transport, while certain specialist profiles need a dedicated frozen-return pathway. Do not freeze a sample unless your kit instructions specifically require it.

When will I receive my results?

Most routine panels are typically reported within 1–3 working days after a suitable sample reaches the laboratory. Minerals and heavy metals usually take 3–7 working days, whole-blood histamine 3–5 working days and the plasma neurotransmitter profile 5–7 working days. Transport time is additional. Check the product page for the current turnaround time for your panel.

What happens if my sample is insufficient or unsuitable?

We recommend filling each supplied collection tube to the marked fill line, following your kit instructions, so we have enough blood to perform the requested analyses. If we receive an underfilled tube, we will refund the analysis fee. Shipping charges and the cost of the Tasso device are excluded from the refund. For other collection or transport problems, WHL will advise you on the next steps.

Can you help me choose the right panel?

Yes. Use the WHL test guide or contact the laboratory if you are unsure which panel matches your question, or if you would like help with the preparation and collection requirements for several panels.

Do these tests provide a diagnosis or screen for cancer?

Laboratory results need to be interpreted alongside symptoms, medical history, medication and other findings. They do not replace a medical assessment. The tumor-marker profiles are intended for clinician-guided monitoring or investigation; they cannot independently diagnose or exclude cancer and are not a substitute for established screening programmes.

WHL HomeLab tests provide laboratory information and do not replace medical evaluation or urgent care. Interpret results with your healthcare professional. Check the individual product page for current composition, availability, preparation, collection and return instructions, and turnaround time. Promotional prices may change. Every listed panel price includes Tasso+; €15.95 handling and shipping is added at checkout. Specialist transport requirements may apply.
