IMMUNOLOGY

Detailed explanation-1: -The purpose of examining a blood smear is to check the size, shape, and number of three types of blood cells: Red blood cells, which carry oxygen from your lungs to the rest of your body. White blood cells, which fight infection.

Detailed explanation-2: -A blood smear is a blood test that gives information about the number and shape of blood cells. It is often done as part of or along with a complete blood count (CBC).

Detailed explanation-3: -During this examination of the smear, the pathologists assess the size, shape, and color of the RBCs and WBCs. Also, they estimate the number of platelets present. The quality of RBC is characterized by red cell indices and any deviation in size, volume, or shape of red cells represents an abnormal red blood cell [78].

Detailed explanation-4: -RBC morphology is assessed qualitatively on a well-made blood smear and includes RBC distribution, anisocytosis, poikilocytosis, polychromasia/hypochromasia, and inclusions or organisms. Abnormalities are graded as slight, moderate or marked (or 1+ to 4+).

Detailed explanation-5: -A blood smear is a test for detecting problems in red blood cells, white blood cells, or platelets. It’s sometimes called a peripheral smear for morphology. 1 The test has a wide range of uses. It can be used to tell whether an infection is viral or bacterial.
