Laboratory tests are generally of limited benefit in mycoplasmal pneumonia, as they tend to be nonspecific or within the normal range. For example, elevated erythrocyte sedimentation rates (ESR) may be present but are nonspecific. The white blood cell (WBC) count is generally not helpful in this condition because results may be normal or elevated, and, although hemolytic anemia has been described, it is rare.
