However, if the presence of abnormal WBCs, RBCs or platelets is suspected, a blood film examined by a trained professional is still the best method for definitively evaluating and identifying immature and abnormal cells. The blood sample is placed on a glass slide and stained using a special form of dye; the results can then be are also ordered along with a blood test, as these tests help detect the exact cause of the illness. Findings from the blood film evaluation are not always diagnostic in themselves and more often indicate the presence of an underlying condition and its severity and suggest the need for further diagnostic testing. This test checks levels of two types of cholesterol: high-density lipoprotein (HDL), or … the patient has recently had a blood transfusion. If there are too many platelets, this may increase the likelihood of a blood clot forming. While not every RBC will be perfect, any significant number of cells that are different in shape or size may indicate a more severe problem. Blood film findings may include: RBC (Red blood cells) The test is usually ordered for patients who have symptoms which may indicate a deficiency or disease which affects the production of blood cells. Blood films are examined in the investigation of hematological (blood) disorders and are routinely employed to look for blood parasites, such as those of malaria and filariasis. It is possible to distinguish between the five different types of WBCs and to determine their relative percentages by counting 100 consecutive cells. Red blood cells, which carry oxygen 2.
