Presentation Transcript

  1. Red cell morphology: • In healthy person, the red cells in well spread ,well stained film, they appear as reddish brown round smooth contours with a pale center . • Its size same the nucleus of lymphocyte and has diameters of 6 to 8.5 μ.m RBC in Healthy person Normocytic ( size is normal) Normochromic(Hb content i.ecolour is normal) (The red cells are stained with eosin Y component of rowmanowsky dyes)

  2. Variation in RBCs morphology due to: 1-Abnormal erythropoiesis :production of RBC only 2- increased erythropoiesis 3-decreased Hb formation 4-RBC damage These causes result in the following variation: • Anisocytosis → variation in size (micro or macro) • Poikilocytosis → variation in shape • Variation in colour • Variation in content

  3. 1. Variation in Size:

  4. 2-Variation in shape:

  5. 3- Variation in colour:
