Isocyanates Analysis - Biological Monitoring Kits


Isocyanates are one of the leading causes of occupational asthma in the UK. As respiratory sensitisers, exposures to isocyanates should be kept as low as reasonably practicable and this often requires the use of respiratory protective equipment (RPE). Biological monitoring is a simple and cost-effective way of checking that control measures are working and being used correctly.

More information on isocyanate testing is available on our website.

On completion of your online order, the relevant sample kits, packaging and paperwork will be sent to you - simply collect the samples and return to HSE Science and Research Centre for analysis.  Please note: the name and address used in this system will be used as the delivery address for kits and result reports.  The requestor is responsible for obtaining informed consent from workers and for communicating the results, observing the personal data nature of those results.

These kits are designed for use by employers and occupational health providers, not individuals.

Only request those isocyanates in use on the day of testing to avoid confounding from other industrial chemicals as this can make interpretation of results much harder.

Please note that a minimum of 10mL urine is required for this test. Do not send samples with less than this volume rather re-sample at another time.

We offer a comprehensive testing service outside of what is currently available online.  Please see our full price list. To order kits for these tests, please email

We also offer other online tests.
