How to record where a sample is stored

Recording the freezer position of a sample lets anyone find the physical tube later, without opening every box. This matters most for samples held for retesting, for confirmatory work, or for a quality review.

Before starting

  • Samples registered in InteLIS
  • The freezer, rack, box, and position where the tube goes
  • Permission to view test requests

The freezer names come from a list the administrator maintains. If a freezer is missing from the list, ask the administrator to add it under ADMIN → System Configuration → Lab Storage.

Open the storage page

  1. Go to HIV VIRAL LOAD → Request Management → View Test Requests.
  2. Select Samples Storage at the top right of the list.

Record a position

  1. Choose the Lab and the Freezer.
  2. Filter to the samples being stored, using Sample Collection Date, Sample Received at Lab Date, or Facility Name.
  3. Select Get Samples.
  4. For each sample, fill in the storage details.
Field What to enter
Rack The rack inside the freezer
Box The box inside the rack
Position The position inside the box
Volume(ml) The volume stored, if the lab tracks it
Date out The date the sample left storage, filled in on removal
Comments Anything needed to find or interpret the sample
  1. Select Save.

Record the position at the moment the tube goes into the freezer. A position written down later, from memory, is the position the tube was meant to go in, not necessarily where it is.

Record many samples at once

Where a whole box goes in at one time, use Storage Bulk Upload. Fill the spreadsheet with the Sample IDs and their positions, then upload it.

Record a sample leaving storage

Set Date out on the sample's row and save. The sample stays on record with its history, so a later search shows where it was and when it left.

Find a stored sample

  1. Go to HIV VIRAL LOAD → Management → Freezer/Storage Reports.
  2. Filter by freezer, by date, or by facility.

The report gives the current position of each sample and its storage history. Export it to a spreadsheet for a stock check against the physical freezer.

Confirm it worked

Search for the sample on the Samples Storage page. Current Storage shows the freezer, rack, box, and position just recorded.
