This sample kit is for workers using isophorone diisocyanate (IPDI). If you are uncertain, we can check safety data sheets for you. Relevant CAS numbers on safety data sheets include 4098-71-9.
This isocyanate is commonly found in two-pack spray paints.
HSE recommends annual testing of spray painters in the motor vehicle repair industry using isocyanate-based paints. Further information on testing can be found on our isocyanates page.
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.
Due to the fast elimination of IPDI exposure, urine samples should be collected within an hour of the end of exposure. Spraying should last at least 15 minutes; if you are doing several spray sessions across an hour or two, give your sample at the end of the session.
There can be confounding from isophorone diamine (an important curing agent for epoxy resin systems) so please check for any co-exposure if elevated results are found.
Due to exceptional demand, our current turnaround time is around 7 weeks from receipt. If you wish to proceed with your order then please do take this in to consideration. We are making every effort to bring this down to 20 working days (which will be our target going forward) but we are currently unable to increase capacity.
