Flashcards in An Introduction to the Anemias (Module 1) Deck (9)
___________ is a condition in which the hemoglobin concentration of the blood is reduced below the normal reference interval for the age and sex of the patient, typically below 140 g/L in adult males and below 120 g/L in adult females.
_____________ is a condition in which the erythrocyte count in the blood and usually also the hematocrit is increased above reference intervals.
Absolute anemia occurs when the hemoglobin concentration is decreased due to: 2 things.
1- decreased absolute numbers of erythrocytes int he blood
