Screening Bench

Record ABO/Rh grouping and every TTI test for each donation, then release the units to stock or discard them, and print the screening register and certificate.

The Screening Bench holds every donation waiting for its tests. A unit leaves quarantine only when its group is recorded and every test is negative. Any reactive result discards the units and defers the donor.

Before you begin

  • Your role needs Enter / Verify TTI Screening & Grouping. See Users & Roles.
  • The test list comes from Screening tests in Blood Bank Setup. Every active test must have a result before release.

Where to find it

Open Blood Bank → Work → Screening Bench.

Find the donations

Use the tabs at the top:

  • Pending: donations still in quarantine.
  • Released: donations whose units went to stock.
  • Reactive — discarded: donations with a reactive result.

Each row shows the donor, the collection time, the group and one column per test, such as HBSAG, HCV, HIV, MP and VDRL.

Enter results and release

  1. Click Enter results on a pending donation.
  2. Choose the ABO group and the Rh (D).
  3. For each test, click Negative or Reactive. Add the Kit lot and the Method if you record them.
  4. Click 💾 Save to keep the results without deciding yet.
  5. When every test has a result, click Verify & release, or Verify & discard if any result is reactive.
  6. Confirm the message.

Print

  • 🖨 Print prints the TTI Screening Register for the tab that is open.
  • 🖨 Print Report in a donation prints its TTI Screening Report on A4, with Tested by and Verified by signature lines.

Common questions

The verify button stays greyed out. Choose both the ABO group and the Rh, and give every test a result.

A warning says the donor was previously grouped differently. The donor record has another group. Repeat the grouping before you release the units.

Can I correct a result after verifying? No. Released and discarded screenings are read-only. Discard a released unit on Units & Inventory if it must not be used.

I separated the Whole Blood before screening. What happens to the components? They wait in quarantine too. Verifying releases or discards all of them together.
