What is a peripheral blood smear test?
A peripheral blood smear (PBS) test is a procedure used by doctors to evaluate your red and white blood cells, as well as your platelets.
Your doctor may order a peripheral blood smear in addition to a CBC (complete blood count) or if your CBC shows abnormal blood cell activity.
A microscopic examination of your cells may help the doctor determine how and why your blood cells appear abnormal and aid in assessing your health condition.
