Other names: peripheral smear, peripheral blood film, smear, blood film, manual differential, differential slide, blood cell morphology, blood smear analysis It leads to chains of hemoglobin in the blood cell, which forces the cell into a sickle shape. Label the blood smear with patientâs name, date and identification number. The blood sample is sent to a lab. The smear provides this information: The number and kinds of white blood cells ( differential, or percentage of each type of cell) The number and kinds of abnormally shaped blood cells. There, the lab technician looks at it under a microscope. It is often done as part of or along with a complete blood count (CBC). A blood smear, also referred to as a peripheral smear for morphology, is an important test for evaluating blood-related problems, such as those in red blood cells, white blood cells, or platelets. Place a drop of the antiserum that is associated with each depression. We applied subject-wise cross-validation, where the correct WBC class labels for each cell were determined by staining the WBCs and gating them based on the emitted fluorescence. 2. ; Make 2 smears, allow to air dry, and label clearly.
