What is the test for deliberate indifference to medical care?

manifested by prison doctors in their response to the prisoner's needs or by prison guards in intentionally denying or delaying access to medical care...." Estelle, 429 U.S. at 104-05. "A medical need is serious if failure to treat it will result in significant injury or the unnecessary and wanton infliction of pain." Peralta, 744 F.3d at 1081 (internal quotation marks and citations omitted). "A prison official is deliberately indifferent to that need if he 'knows of and disregards an excessive risk to inmate health.'" Id. at 1082 (quoting Farmer v. Brennan, 511 U.S. 825, 837 (1994)).

The test for deliberate indifference to medical need is thus two-pronged and has objective and subjective components. See Wilhelm v. Rotman, 680 F.3d 1113, 1122 (9th Cir. 2012). To establish such a claim, a prisoner must first "show a serious medical need by demonstrating that failure to treat [the] prisoner's condition could result in further significant injury or the unnecessary and wanton infliction of pain. Second, the plaintiff must show the defendants' response to the need was deliberately indifferent." Id. (internal quotation marks and citation omitted).

As to the first, objective prong, "[i]ndications that a plaintiff has a serious medical need include '[t]he existence of an injury that a reasonable doctor or patient would find important and worthy of comment or treatment; the presence of a medical condition that significantly affects an individual's daily activities; or the existence of chronic and substantial pain.'" Colwell v. Bannister, 763 F.3d 1060, 1066 (9th Cir. 2014) (citation omitted).
