Peripheral Blood Smear (PBS O R PBF)

Peripheral Blood Smear (PBS / PBF) is a hematological test in which a thin layer of blood is spread on a glass slide and examined under a microscope. This test provides detailed information about red blood cells, white blood cells, and platelets, including their morphology and distribution. It is essential for diagnosing various blood disorders such as anemia, infections, leukemia, platelet abnormalities, and parasitic infections like malaria. PBS is often performed alongside Complete Blood Count (CBC) to clarify abnormal results and identify underlying causes. It plays a vital role in diagnosing, monitoring disease progression, and guiding further investigations.
