Answer #1

peripheral blood smear test is used to quantify the amount of blood cells present. They help in detection and quantification of generally 3 types of blood cells namely RBCs, WBCs and platelets. Post a smear slide preparation, the microscopic analysis of the blood helps us to determine the number and shape of your red and white blood cells and platelets to see confirm if the count and morphology is normal. A blood smear also

detect parasites in your blood. Therefore if there is an bacterial infection near the site of collection , the WBC count will be higher.

If you are suffering from anemia, the RBC count is abnormal or the morphology is different. Therefore in the microscopic examination of this sample, the abnormalities will be seen. You might observe siderocytes, denatured Hb etc.

If you observed an average of 14 platelets per high power field on a peripheral blood smear prepared from the needle tip and your laboratory allowed correlation between the direct instrument count and the blood smear estimate of 20%, what range would you expect the instrument count to be? Is this platelet estimate within an acceptable reference range?
