A quick walkthrough of entering and submitting your proficiency test results in the Lake Balance PT portal.
The screenshots use sample data (a demonstration lab and made-up readings), not real results.
Sign in to the Lake Balance PT portal. Your Active PTs & next steps list shows your test, with Submit measurements as the next step. Click it to open your PT. (You can also open it from My Tests in the left menu.)


On your PT page, click Enter measurements. It takes you to the Your measurements section, where you enter your results. There is one set of results for each participant, shown as tabs at the top.

Pick a participant tab (Participant 1, Participant 2, and so on). For each Measurement point, enter your Reading and your expanded Uncertainty (k=2). Enter both values for every point. You can rename a participant in the Participant name / identifier box.

Below the table, fill in Temperature (include the unit), Humidity (% RH), Date performed, and any Comments.

In the Electronic signature box, type your full name and tick the confirmation box. A signature is required for each participant before you can submit. You can save an unsigned draft.

Click Save draft at any time to keep your work and come back later. Your entries stay in place, and a Lab code is assigned to each saved participant. When every participant has all points entered and signed, click Submit complete results. If something is missing, a red message tells you what to fix.


Your PT now shows Results are being reviewed and a Submitted measurements table. To correct a submitted value, use the Contact our team link on that page. If you have an uncertainty budget or other supporting document, you can upload it under Documents (PDF, PNG or JPEG, up to 5 MB).


As soon as Lake Balance reviews your results, your PT page shows Your PT result: Pass or Fail overall and for each participant, with how many points passed. It appears right away, before the kit is on its way back. The En value for each point and the final report are released once payment is received and the kit's return shipment shows in transit with the carrier. Questions about payment? Use the Contact billing link on the page.
