1. Testningsförfarande för bestdmning av koncentrationen av vissa plasmakomponenter i helblod, kännetecknat av att en halvpermeabel membran som omfattar en matris av förbindelse-fibriller av svälld polytetrafluoroetylen behandlas med ett ytaktivt ämne för att göra membranen hydrofil och genomtränlig för helblodets plasmakomponenter men ogenomtränglig för hel-blodets cell- och partikelbestdndsdelar, varvid den halvper-meabla membranen innefattar porer som görs hydrofila medelst behandlingen med det ytaktiva ämnet; den halvpermeabla membranen stalls ovanpd det med hänsyn tili blodplasmakomponenten reaktiva omrddet; ett helblodprov bringas pd den halvpermeabla membranen sd att provets plasmakomponenter gdr genom membranen tili det reaktiva omrddet samtidigt som rörelsen av blodcell- och partikel-beständsdelarna hindras med hjälp av membranen; membranen separeras frän det reaktiva omrddet; och koncentrationen av plasmakomponenterna i provet bestdmms genom att mätä omfattningen av den av plasmakomponenterna dstadkomna ändringen inom det reaktiva omrddet.
2. Förfarande enligt patentkravet 1, kännetecknat av att den halvpermeabla membranen täcks med en absorberande beldggning före bringande av provet pd membranen, varvid den absorberande beläggningen utbreder provet över membranen och sdledes dven utbreder provets plasmakomponent över det reaktiva omrddet.
3. Förfarande enligt patentkravet 2, kännetecknat av att beläggningen har formats av ett hydrofobt material som har be-handlats med ett ytaktivt ämne för att göra porerna hydrofila.
