Description
A blood smear is a blood test used to look for abnormalities in blood cells. The test provides information on the number and shape of these cells, which can help doctors diagnose certain blood disorders or other medical conditions. Irregularities in the number or shape of your red blood cells can affect how oxygen travels in your blood.
Precaution
Before this test, it’s important to tell your doctor about any prescription or over-the-counter medications, supplements, and vitamins you are currently taking.
