A 62-year-old patient presents with complaints of fatigue, pallor, and occasional shortness of breath. On examination, he has pale conjunctiva and mild glossitis. A CBC reveals the following results: Hemoglobin: 8.5 g/dL  MCV: 115 fL WBC: 3.2 x 10⁹/L  Platelets: 95 x 10⁹/L  Reflex Tests Ordered: Serum Vitamin B12: Low Serum Folate: Normal Serum Iron: Normal Bone Marrow Biopsy: Hypercellular with dysplasia in all three cell lines. Based on the clinical findings and laboratory results, which is the most likely diagnosis, and what features differentiate this diagnosis?    

Evaluate the hematology data and identify the most likely diagnosis: WBC Count: 12.5 x 10⁹/L RBC Count: 4.6 x 10⁶/µL Hemoglobin (Hgb): 13.8 g/dL Hematocrit (Hct): 41% Platelet Count: 180 x 10⁹/L Differential Count: Neutrophils: 35% Lymphocytes: 50% Monocytes: 10% Eosinophils: 3% Basophils: 2%  

A patient’s RBC morphology appears as shown in the image below. Which is the most appropriate initial test to distinguish the cause of this disorder?

Evaluate the images of scatterplots from the Sysmex-XN. Match each diagnosis with the corresponding scatterplot image.  

A patient presents with easy bruising and petechiae. A CBC shows a low platelet count flagged by the automated analyzer, so a manual platelet count is performed using a hemocytometer for confirmation. A 1:100 dilution of the blood sample is prepared, and platelets are counted in the center square of both sides of the hemocytometer grid. The total platelet count from both center squares is 30 platelets. What is the platelet count in x10⁹/L? Enter the numeric value only.

Based on observation of the image below, how would you classify this finding?  

What is the MCH in picograms (pg)?
