From request to report
Agree the route before the first order.
Before ordering for a client, agree the request route, payment arrangement, collection address and authorised report recipients with WHL. Keep your practice account details separate from the patient’s details.
Agree your ordering route
New to WHL? Contact the team to arrange professional access or a dedicated practice ordering page. Existing practitioners should use their agreed WHL process.
Choose tests and confirm who pays
Check panel contents and overlapping tests. Confirm whether the client pays directly or the practice is invoiced. Practice invoicing must be agreed in advance; it is not automatic.
Arrange collection and report access
Confirm sample requirements, kit delivery and return transport before collection. Confirm the patient’s authorisation before arranging practitioner access to results.
Payment and responsibility
Choose a clear payment arrangement.
Guide your client to their own order.
Agree the test selection with your client. The client uses their own details for their order and payment. Ask WHL how to connect the request with your practice.
Browse testsAgree client payment or practice invoicing.
Contact WHL before using a new ordering arrangement. Confirm the payer, kit delivery address and how the client approves the request. Dedicated practice pages and invoice arrangements are agreed individually.
Discuss your ordering routeKeep these details separate
One request. Four clear roles.
A practice account, the person being tested, the payer and the report recipient may be different people. Confirm each role rather than replacing one person’s account details with another’s.
- Patient
- The person whose sample is tested.
- Practitioner
- The professional requesting or advising on testing.
- Payer
- The client or practice responsible for the invoice.
- Report recipient
- The patient and other recipients authorised through the agreed WHL process.

Practical questions, answered.
What is L@SIST, and which account should I use?
L@SIST is the professional login linked from this page. Use the professional access agreed with WHL. The website’s My Account is for shop orders; creating a shop account does not by itself arrange professional portal access. Contact WHL if you are unsure which account to use.

How do I start working with WHL as a practitioner?
Use Start working with WHL to introduce your practice, country and testing areas. Before your first request, agree professional access, the ordering route and payment arrangements with the team. Keep patient information out of this initial general enquiry.
How do I order tests for a patient or client?
Use the professional ordering route agreed with WHL, or guide your client to place their own order with their own details. Keep the patient, practitioner, payer and authorised report recipient distinct. Do not replace your saved practice account details with the patient’s details.
Can the client pay directly, or can my practice be invoiced?
Agree who pays before placing the request. A client can use their own shop order and payment details. Practice invoicing or another professional payment arrangement must be confirmed with WHL in advance; it is not automatic. Also confirm the kit delivery address and authorised report recipients.
Can I combine individual tests and panels?
Review the listed markers to identify overlapping tests. Before collection, ask WHL to confirm sample compatibility, required tubes, volumes and handling for the complete selection. Do not assume that one collection device or one sample is sufficient for every combination.
Can every blood test be collected at home?
No. HomeLab blood panels include a Tasso device where offered. Other blood tests may require professional collection, different tubes or special handling. Confirm the complete selection with WHL before arranging collection.
Where do I find preparation and collection instructions?
Read the information for the selected tests and the instructions supplied for the collection kit or appointment before collection. Fasting, timing and sample handling can differ between tests. If instructions are missing or conflict for a combined selection, ask WHL to confirm the correct preparation first.
Are collection, kit delivery and sample return included in the price?
This depends on the test, destination and agreed service. Confirm collection, handling, kit delivery and return transport charges before the order is paid. For testing outside the Netherlands, agree the collection and transport arrangements with WHL before collecting a sample.
How long will the results take?
Check the expected reporting time for the selected test and confirm it with WHL when planning a combined request. Ask when that period starts and whether components are reported separately. Do not assume one reporting time applies to every test or that it starts on the payment date.
Who can receive the results?
Agree authorised recipients with the patient and WHL. Access is not granted simply because a practitioner’s name appears on an order. Use the secure process arranged with WHL; payment responsibility alone does not establish permission to receive results.
Is interpretation or a follow-up consultation included?
Included reporting and support vary by test or panel. Check the selected product and confirm whether a report explanation or follow-up appointment is included or booked separately. You can request an anonymised example report to understand the format before choosing your testing route.
Where do I get ordering or L@SIST login help?
Use Contact & Help for account access, ordering routes, collection arrangements and portal problems. Describe a general login or technical issue without including patient information. For case-specific questions, use the secure communication route agreed with WHL. Contact WHL
