Förfarande för analys av ett trombocytprov för fastställande av en ytantigen i trombocyterna, kännetecknat av att det omfattar följande steg: 10 a) bildande av en reaktionsblandning som sensibiliserar trombocyter genom att blanda ett trombocytprov med en anti-kroppmolekyl som förmär immunreagera med ytantigen i trombocyterna för att bilda ett trombocyt-immunkomplex, 15 b) uppehällande av nämnda sensibiliserade reaktionsblandning tillräckligt länge för att bilda nämnda trombocytimmun-komplex, varvid antikroppssensibiliserade trombocyter bil-das, 20 c) dekomposition av nämnda sensibiliserade trombocyter för att erhälla en vattenhaltig blandning innehällande ett upp-löst trombocytimmunkomplex, da detta immunkomplex bildats i steg b), 25 d) bildande av en fästande reaktionsblandning genom att blanda nämnda vattenhaltiga blandning med en fast bärare som förmär immunreagera med nämnda lösta trombocyt-immunkomplex, e) uppehällande av nämnda fästande reaktionsblandning 30 tillräckligt länge för att den fasta bäraren skall immunreagera med ett eventuellt närvarande upplöst trombocytim-: munkomplex, sä att en immunreaktionsprodukt i fast fas upp- kommer, vilken ätgärd ästadkommer en bestäende fast bärare, 35 f) bildande av en markerande reaktionsblandning genom att blanda den fasta bäraren med en markerad antikroppmolekyl som förmär immunreagera med nämnda trombocyt-immunkomplex av I immunreaktionsprodukten i fast fas, li 95082 g) uppehällande av nämnda markerande reaktionsblandning tillräckligt länge för att nämnda markerade antikroppmolekyl skall immunreagera med den eventuella immunreaktionsproduk-ten i fast fas som bildats i steg e), sä att ett markerat 5 fastfaskomplex bildas, h) fastställande av förekomst av ett eventuellt markerat fastfaskomplex som bildats i steg g), och sälunda fastställande av förekomst av en eventuell ytantigen i nämnda trom- 10 bocytprov. • I
