Barb Bancroft's approach to interpreting lab tests is a "must hear" for nurses in all areas and nurses at all levels. Each webinar is packed with a number of practical pearls that can be applied to your patients in the hospital, in the primary care facility, or in the ICU.
Windows on an Inner World: the White Blood Cells

Basophils-cells of allergic response
Understand the three lab tests used to determine the inflammatory response. (20 minutes)
