Abstract:
Method for determining the immune defence activity of blood by incubating the whole blood in the presence of nutrient medium and anticlotting agent in a blood sampling system used for blood sampling purposes, blood incubation taking place substantially immediately following blood sampling at approximately 37Â° C. and for 8 to 60 hours, without prior separation of the red corpuscles, by bringing the blood into contact in extracorporal manner with blood anticlotting agent which includes anticoagulant heparin, at least one stimulant (activating agent) for stimulating the blood cells to deliver messenger substances, followed by a separation of blood corpuscles from the supernatant without prior centrifuging, and the determination of the immune defence activity using the messenger substances contained in the supernatant, using a medical blood sampling system with a displaceable syringe piston, with a temporarily permeable partition for the incubation of whole blood in the blood sampling system and subsequent separation of supernatant serum from the blood corpuscles with the aid of the partition.
