Optimizing Your Sample Application Process

For the most optimized workflow when applying a patient or Quality Control sample to the Test Strip, please refer to the guidance provided in this Technical Bulletin, which is consistent with the instructions outlined in the Platform User Manual.

Applying a sample to the Test Strip

Following the insertion of a LumiraDx Test Strip, the Instrument display will prompt when to apply the sample. Apply ONLY one drop of the sample directly to the circular Sample Application Area on top of the Test Strip.

Page 1 Example:

The instrument display shows a timer counting down from 03:59, with a prompt to 'Apply sample to Test Strip' and 'Only apply one drop'.

Another screen shows a 'Sample Application' prompt, stating 'Only apply one drop. Sample detection may take up to 15 seconds.' The timer continues.

A 'Quality Control Test' screen shows 'Sample detected' and prompts to 'Close door to continue' with a timer of 00:14. Another screen shows 'Apply QC solution to Test Strip' with a timer of 01:55.

Visuals on page 1 depict applying a single drop of sample to the test strip with a red cross (❌) indicating an incorrect application and a green checkmark (✔️) indicating a correct application.

Important Notes on Sample Application

IMPORTANT: Sample detection and confirmation on the Instrument can take up to 15 seconds on some Test Strips. Whilst waiting for the confirmation, DO NOT apply any additional sample drops. If you think you have not applied the sample correctly, cancel the test on the Instrument, remove the Test Strip, and start another test using a fresh strip.

When the sample is detected, the Instrument will sound (if sounds are enabled) and a confirmation message will be displayed.

The touchscreen of the LumiraDx Instrument will request the user to close the door once the Instrument has detected the sample.

Removing the Test Strip from the LumiraDx Instrument

The Instrument will prompt to remove the Test Strip.

Gently pull the blue label end of the Test Strip to remove and dispose.

Do NOT bend the Test Strip when removing from the instrument. ⚠️

Page 2 Example:

The instrument display shows 'Test Complete' and prompts to 'Open door and remove Test Strip'.

Visuals on page 2 show the correct and incorrect methods of removing the test strip, with a red cross (❌) for incorrect removal and a green checkmark (✔️) for correct removal.

For further information refer to the “Preparation for Testing” chapter in the Platform User Manual for handling Test Strips, inserting and removing Test Strips and sample collection and application instructions.
