The histamine in a sample is determined by contacting the sample with a histamine binding agent, such as glass, which has been treated, e.g., with a polar organic polymer, to reduce the affinity of the agent for an interfering component of the sample while substantially retaining the agent's histamine-binding capacity. Such an agent facilitates determination of histamine in whole blood samples. Preferably, the agent is provided as a conglomerate of histamine-binding bodies, such as glass fibers, in a binder. Preferred binders are polyvinyl acetate, a vinyl acetate/ethylene copolymer, and polyvinyl alcohol or combinations thereof. |
