      الاجابات الصحيحة:
      1- A
      2- E:
      لأن BM tumors will cause extramedullary hemopoiesis
      Thankyou Mr.Hematologist.

            الاجابات الصحيحة:
            1- C
            2- C
            Because :
            1- S and G and D all have the same electrophoretic mobility at alkalaine electrophoresis. (احفظها كالتالي: سجد (س لـ S ) (ج لـ G ) و (د لـ D ).
            2- Hb-H and Hb Bart's both are very fast moving.
            Hb-H is composed of 4 beta globin chains, while Hb Bart's is composed of 4 gamma globin chains, usually we see both of them in alpha thalassemia (Hb-Barts is incompatible with life).
            Thank you Mr. Hematologist
            and Now for the 2 new questions..........

              B- Is the commonest RBC enzyme deficiency.

              D- Should be diagnosed during acute hemolysis phase.

                  6- D
                  G6PD enzyme is carried on the X chromosome, this is why is seen in males more more tham females. In acute hemolysis there will be reticulocytosis, and reticulocytes are characterized by increasing amounts of G6PD enzyme, so G6PD enzyme in deficient patients will be normal during hemolytic episodes.

                          السؤالين الجديدين:
                          9] Hemoglobin can be increased erroneously when there is:
                          A] Leukopenia.
                          B] Increased plasma hemoglobin
                          C] Paraproteinemias
                          D] Low triglycerides levels.
                          ُE] High RDW
                          10- When precursor cells are present in a blood film, they tend to accumulate in the:
                          A] Tail.
                          B] Edges.
                          C] Multilayer zone.
                          D] Monolayer zone.
                          E] Thick area

                          تمنى من الله التوفيق والسداد

                              الاجابات الصحيحة هي:
                              9- C
                              Hemoglobin is increased errornously when there is leukocytosis (high WBC count), Lipidemia (high lipids), and high protein. With paraproteinemia there is high protein!!!!
                              10- B
                              Immature precursor cells tend to accumulate at the edges of the blood film because of there big size. This is why in blood film preparation it is recommended that the film should not touch the edges of the slide.!!!
                              Thank you
                              Now to the next 2 questions ........
