Screen and release a donated unit

Group a donation, enter every TTI test result and verify it, so the units are released to stock or discarded and the donor deferred.

Every donation stays in quarantine until it is grouped and all its screening tests are done. This task records the results and makes the release or discard decision.

Before you begin

• Your role needs Enter / Verify TTI Screening & Grouping. See Users & Roles.
• The tests listed come from Screening tests in Blood Bank Setup.

Where to find it

Open Blood Bank → Work → Screening Bench and stay on the Pending tab.

Enter the results

1. Click Enter results on the donation.
2. Click the ABO group: A, B, AB or O.
3. Click the Rh (D): Positive or Negative.
4. For each test, click Negative or Reactive.
5. Type the Kit lot for each test. Change the Method if you used a different one.
6. Add Remarks if needed.
7. Click 💾 Save if another person will verify.

Verify

1. Open the donation again if you saved it.
2. Check the group against any warning that the donor was previously grouped differently.
3. Click Verify & release when all tests are negative.
4. Confirm the message, which shows the group the units will carry.

All units from the donation become Available with that group, including any components already separated. The donor record takes the group.

When a result is reactive

1. Click Reactive for the test.
2. Read the red warning.
3. Click Verify & discard and confirm.

Every unit from the donation is discarded with the reason TTI reactive. The donor is deferred, permanently or for the days in your rules, and the reason names the test and donation. The donation moves to the Reactive — discarded tab.

Common questions

Verify & release is greyed out. A test still shows pending, or the group or Rh is missing.

Can two people share the work? Yes. One enters and saves the results, another opens the donation and verifies. The register shows Tested by and Verified by.

I verified by mistake. A verified screening cannot be reopened. Discard the released units with a reason on Units & Inventory and record the issue in your quality log.
