Place a retest

Last updated: June 30, 2026

Re-run a test that came back out of spec. Find the test, start a retest, choose whether to send a new sample or use the one already at the lab, then check out.

Prerequisites: A completed test, typically one with an out-of-spec result.

1. Find the test

In the left navigation, open Orders (or Tests) and click into the order that has the out-of-spec test. The test row shows a COMPLETED (OUT-OF-SPEC) status and a Retest button on the right.

2. Click Retest

Click the Retest button tied to the test you want to re-run.

3. Choose how to handle the retest

In the How should we handle this retest? dialog, pick one:

  • I’ll send a new sample — ship a fresh sample to the lab.

  • Use the sample you already have — re-run the existing sample.

Click Continue.

Note: Light Labs holds samples for 30 days after testing. If Use the sample you already have is unavailable, the sample has passed the 30-day retention window and was disposed of — send a new sample instead.

4. Check out and place the retest

A new order is queued with the retest. Review it, then Check out and place the order the same way you place any order.

Outcome

The retest is placed as a new order. If you’re sending a new sample, ship it to the lab; otherwise the lab re-runs the sample it still has on hand.
