Test your staff and students on-site in just 15 minutes
Avoid the disruption, cash costs, and reputational damage of sending teachers and students home while waiting days for NHS/private lab results. Our tests allow you to screen your school more frequently, detecting early or asymptomatic cases.

Rapid antigen tests enable you to make the right decision based on hard data, rather than having to assess hard-to-pin down symptoms
BLOK Rapid Antigen Test
Immunofluorescence Lateral Flow technology
Detects presence of virus genetic material
Can tell if someone is currently infected
Can detect early or asymptomatic cases
Automated, simple yes-or-no results
Results ready on-site in less than 15 minutes
Throughput: 5-50 tests/hour
Compliant: CE- and NMPA-marked
Sensitivity: 94% (true positive rate)
Sensitivity: 100% (true negative rate)
Highly accurate results
A recent pre-publication Lancet study showed this solution to have a 94% sensitivity, and a 100% specificity.
No test achieves 100% sensitivity, and 94% sensitivity is extremely high – that means 94% of those who have the coronavirus would be picked up by the test. 100% specificity means that there will be no false positives, so you can be sure that a positive test really is just that, positive.
CE-marked: approved for UK use
The testing kit and analyser machine are CE-marked, meaning they’re approved for use in the UK and Europe.
Your school nurse is qualified to administer the tests on-site.
Established technology
Rapid antigen tests are well-established and used in the diagnosis of other respiratory diseases, like the flu. In the United States, the FDA has granted emergency use authorization (EUA) for multiple antigen tests that can identify SARS-CoV-2 using the same principle of immunofluorescence lateral flow technology.
What we provide
We provide you with testing hardware, supplies, and guidance so you can get your own testing programme running in no time
BLOK fluorescence immunoassay analyser
Health passport for recording results
Supply of cassette assays and expendables
Bespoke testing protocol design to your business
See it in action

Guidance for testing in schools
We also provide you with protocols and suggested guidance so that you know exactly what to do in specific situations during testing, including:
How to set up a testing programme
How to perform tests/operate the machine analyser
Who and how often you should test
What to do if a teacher/student shows symptoms
What to do if a teacher/student tests positive
How to react if a teacher/student tests negative
How it works
Testing happens entirely on-site, and require a swab sample, a cassette assay, saline reagent, and the BLOK fluorescence immunoassay analyser – all of which are included in our kit. Even though the process doesn’t require any specialised training, tests must be supervised by a school nurse or other qualified healthcare professional.
1. Collect
Perform swab at the patient’s throat or nose.
2. Mix
Mix swab with reagent in the provided tube
3. Place solution
Place 3 drops of the resulting solution in the testing cassette
4. Analyse
Insert cassette into the machine and wait for the result
