Laboratory Animal Allergens
Laboratory animal allergens (LAA)
are recognised by HSE as a significant cause of occupational
allergic disease in the UK. Consistently ranked amongst the top
causes of occupational asthma, these allergens are susceptible to
becoming airborne and contaminating surfaces or clothes leading to
sensitisation of individuals and allergic symptoms.
Our laboratory animal allergen
service provides UKAS-accredited immunoassay methods for the
analysis of rat & mouse urinary protein (Rat n1 & Mus m1),
with internal quality controls and supporting data for all our
recommended guidelines for transportation & storage. Currently,
we can also provide guinea pig albumin upon request, with a major
urinary guinea pig allergen assay currently under development. All
of the above can be tested on a single filter or wipe sample
allowing our clients to minimise the sampling workload.
Exposure monitoring can be
performed as static air, personal air - providing information about
specific task-related exposures - or surface wipe samples. Wipe
kits are provided free of charge & can be ordered ahead of the
sampling work. Contact us to place an order of for further
information on wipe kits.
Limits of detection are appropriate
for all sampling times even short term (10-15 minute sampling
times) where the detection limit for MUP & RUP are
approximately 1-2 nanograms per cubic meter (ng/m3) when
sampling at 2 litres per minute (2 L/min).
HSL also offer interpretation on
LAA results to our clients, based on the distribution of the
extensive cumulative, anonymised data for atmospheric and surface
monitoring. These data have recently been published.
Results are reported securely & confidentially solely to the
customer within the agreed timeframe.
