What is the test for maintaining an Eighth Amendment claim based on prison medical treatment?

Not every claim by a prisoner that he has received inadequate medical treatment states a violation of the Eighth Amendment. To maintain an Eighth Amendment claim based on prison medical treatment, plaintiff must show (1) a serious medical need by demonstrating that failure to treat a prisoner's condition could result in further significant injury or the unnecessary and wanton infliction of pain, and (2) a deliberately indifferent response by defendant. Jett v. Penner, 439 F.3d 1091, 1096 (9th Cir. 2006).
