Alter, Tumuaki o te Rōpū Mate Pūrongo i te Tari Whakawhanaunga Hauora i te National Institutes of Health, me tana rōpū rangahau te āhua o te nuinga o nga take mate mate pukupuku whai muri i te whakaheke i te mate pukupuku A, i te mate pukupuku B rānei. Ahakoa tēnei kitenga, ko ngā mahi rangahau o te ao ki te tautuhi i te huaketo, i huaina i te tīmatanga ko te kore-A, te kore-B hepatitis (NANBH), i taka ki te tekau tau i muri mai. I te tau 1987, i whakamahia e Michael Houghton, Qui-Lim Choo, me George Kuo i Chiron Corporation, e mahi tahi ana me Daniel W. Bradley i nga Whare mo te Whakahaere Mate me te Arai, he huarahi whakakotahitanga ngota hou hei tautuhi i te rauropi kaore e mohiotia ana me te whakawhanake i tetahi whakamatautau taatai. I te tau 1988, i whakapumautia e Alter te huaketo ma te tirotiro i tona aroaro i roto i te roopu tauira NANBH. I te Paenga-whāwhā 1989, i whakaputaina te kitenga o te HCV i roto i nga tuhinga e rua i roto i te niupepa Science. I arahina te kitenga ki ngā whakapainga nui i roto i te tātaritanga me te whakapai ake i te maimoatanga antiviral. I te tau 2000, i whakahonoretia a Dr. Alter raua ko Houghton ki te Lasker Award for Clinical Medical Research mo "te mahi pai ki te kitenga o te huaketo e puta ai te mate pukupuku C me te whanaketanga o nga tikanga tirotiro i whakaiti i te tupono o te mate pukupuku-whakaputa-whakaputa i te US mai i te 30% i te 1970 ki te kore rawa i te 2000. "I tono a Chiron mo nga mana motuhake mo te huaketo me tona taatai. Ko te tono raihana whakataetae na te CDC i whakahekehia i te 1990 i muri i te utu a Chiron $ 1.9 miriona ki te CDC me te $ 337,500 ki a Bradley. I te tau 1994, i whakawakia e Bradley a Chiron, e whai ana kia whakakorehia te mana, kia whakauruhia ia hei kai-whakaputa, kia whiwhi whiwhinga me te moni whiwhi. I whakarerea e ia te whakawa i te tau 1998 i muri i tana hinganga i mua i te kooti amuamu.  Pātai: I tehea tau i whakamahia ai te whakamātautau tātaritanga i te wā o te tāruatanga?
