TRUE OR FALSE. EXPLAIN WHY
The following CBC results are consistent with a diagnosis of aplastic anemia: CBC Results: Hb = 10 g/dL; RBC = 3.8 X1012/L; WBC = 10 X 109/L; Platelet count = 300 X 109/L; Normal Reference Ranges: Hb = 12-16 g/dL; RBC = 4 – 5 X1012/L; WBC = 4.5 -11 X 109/L; Platelet count = 150-400 X 109/L
In Aplastic anemia,
Pancytopenia occurs due to bone marrow failure to produce blood cells
so that the RBC and W BC and Platelets all the blood cells count are decreased

Anemia Case Study A routine admission CBC was analyzed on a 16 year old white male using an automated cell counter. The results were: WBC: 8,200/ul RBC: 4.85 x 106/ul Hb: 20.0 g/dl Hct: 42.5% MCV: 87.6fl MCHC: 47.1 g/dl Do the hemoglobin and hematocrit values match in this case? Explain your answer. Are all of the red cell indices above the usual reference range? Do these abnormal results represent a laboratory error or a blood disorder? Why? What...

A 28-vear-old woman in her 30th week of pregnancy was admit- ted to the emergency room with a spontaneous abortion and vaginal bleeding. Recent history suggested pre-eclampsia as a possible cause. The admission CBC results were WBC 22.0 X 10°/L; RBC 2.81 X 1012/L: Hb 9.0 g/dL; Hct 0.30 L/L; MCV 94.6 fL; MCH 31.3 pg; MCHC 33.0 g/dL; and platelets 142 x 10°/L. The differential count revealed 89% neutrophils, 2% bands, and 9% lymphocytes. RBC morphology showed a normocytic,...
