C-reactive protein in saliva and dried blood spot as markers of stress reactivity in healthy African-Americans.

Noninvasive assessments of C-reactive protein (CRP) in stress contexts have seldom been compared. This study evaluated CRP response to acute social stress as measured in saliva and dried blood spot (DBS). African-Americans (N = 118; mean age = 32 years) participated in a laboratory-based social-evaluative stressor task.
