The peripheral blood film (PBF) is a laboratory work-up that involves cytology of peripheral blood cells smeared on a slide. As basic as it is, PBF is invaluable in the characterization of various clinical diseases. This article highlights the basic science and art behind the PBF.

A Peripheral Blood Film (PBF) is a laboratory procedure that involves examining a blood smear under a microscope to study red and white blood cells, as well as platelets. This test is often used in conjunction with a complete blood count (CBC) and can help diagnose various diseases.

2024年7月18日 · Evaluates white blood cells (WBC, leukocytes), red blood cells (RBC, erythrocytes), and platelets (thrombocytes). The blood smear is examined to investigate hematologic problems (blood disorders) and sometimes to look for parasites in the blood, such as malaria and heartworms. What is a blood smear? Why do I need a blood smear?

Examination of the peripheral blood smear should be considered, along with review of the results of peripheral blood counts and red blood cell indices, an essential component of the initial evaluation of all patients with hematologic disorders.

highlights the basic technique and science behind the PBF. It expounds its laboratory applications, clinical indications and interpretations in the light of various clinical diseases.

Examination of a stained peripheral smear is an integral part of laboratory evaluation of patients. It provides information on red cells, leucocytes and platelets and is used to supplement the information provided by automated hematology analyzers. Any parasite if present, can be identified on the smear.

2024年12月21日 · The (Peripheral Blood Film) PBF test is an indispensable diagnostic tool in hematology that measures blood cell composition. It helps identify red blood cells (RBC), white blood cells (WBC), and platelets as potential signs of health disorders, giving helpful insights into the overall well-being of any given patient. Why Is the PBF Test Important?

2019年4月13日 · Key points include: - Blood smears are used to evaluate anemia, infections, and abnormal cells. Three steps are involved in making blood films: preparation, fixation, and staining. - Under the microscope, a preliminary low and high power scan examines staining quality and cell distribution before a 100-cell differential count at oil immersion.

Keep in mind the clinical context is important when interpreting FBC / PBF for example: • Red cells • Children, males and people living at high altitudes can have higher Hb • In pregnancy, RBC count decreases due to a physiological dilutional effect • Recent blood transfusion can affect the RBC indices • White cells •
