DIAGNOSIS AND CLASSIFICATION Anemia is an absolute decrease in hematocrit hemoglobin concentration, or the rBc count Anemia is not a diagnosis, but a sign of underlying disease
DIAGNOSIS AND CLASSIFICATION Anemia is an absolute decrease in hematocrit , hemoglobin concentration, or the RBC count. Anemia is not a diagnosis, but a sign of underlying disease

C Laboratory findings 1 The Hct is the easiest, most accurate method for detecting anemia, Its result should be interpreted with knowledge of the hydration status and any alteration caused by splenic contraction
