The Workflow
How It Works
From opening the app to a multi-tiered surveillance dashboard — the twelve steps of a SAND test.
01
Set up
Open the app and tell SAND what you are testing, and for whom.
Open SAND app
Select Infection and RDT Type
Enter Person/Patient details
02
Run the test
SAND times the test for you — scan once to start the clock, once again when it is due.
Add Blood and Buffer to RDT as per RDT-specific protocol
Scan RDT immediately in SAND after adding blood and buffer to start timer
Wait for timer alert (SAND auto-enables timer, specific for the selected RDT)
At timer alert, scan the same RDT again in SAND
03
AI reads it
Computer vision interprets the cassette and scores its own confidence.
AI Analysis
Computer vision algorithms:
- Detect control line
- Validate image quality
- Detect test line(s)
- Determine result [positive, negative, invalid]
- Generate confidence score of report

Actions
The result drives the next clinical action, then feeds the surveillance picture.
Take relevant actions prompted by SAND report
Secure upload
Results and metadata are securely uploaded to relevant online database(s).
SAND Dashboard
Multi-tiered authorised access:
- Infection-specific stats with geo-specificity
- Customised views by age, gender, geo-location, institution/programme
