Abstract:
1. A method for testing gas samples or liquid samples for immune-stimulating microbiological substances comprising a) providing a flow through container having a supply opening and an outlet opening, each supply opening and outlet opening having a cover impermeable to microbial substances when closed, and having a separation element or elements inside the flow through container, the separation element or elements comprising filter or filters, b) passing the gas sample or the liquid sample through the supply opening of the flow through container and through the separation element or elements wherein immune-stimulating microbiological substances, if present, in the sample are retained within the filter or filters and wherein the sample exits the container through the outlet opening; c) adding whole blood containing anticoagulants to the surface of separation element or elements thereby contacting the whole blood to the immune-stimulating microbiological substances if present and incubating the filter or filters in the flow through container; d) assaying the whole blood to determine the presence of mediators produced by the whole blood in response to the immune-stimulating microbiological substances if present.
