After the sampling, the movement price of every pump was checked once again in order that the difference between pre- and post-sampling flow charges was in just ±5%. For the very first campaign within the pathology and histology laboratories, The situation of passive and active samplers for private sampling was randomized concerning remaining and correct lapels. For the next marketing campaign within the pathology laboratory, we deliberately placed an active sampler on the best side of each and every participant along with a passive badge around the left aspect to find out an impact of sampler place.
