Answer:
a) anemia
Step-by-step explanation:
The hematocrit is a measure of the volume of erythrocytes compared to the total blood volume.
The normal hematocrit levels are:
Men: 40 - 54 %
Women: 36 - 48 %
Children: 37 - 45 %
In all cases, a hematocrit of 30 is a low level. That means that the person has fewer Red Blood Cells in their blood than normal, which is characteristic of anemia.
