If you want to attempt a specific diagnosis for a person with a blood disorder, would you order a differential WBC count or a total WBC count?

Differential wbc count

The chemical [x1] is added to hematocrit capillary tubes to prevent clotting.

Heparin

Activated monocytes are calle [x1].

Macrophages

The most abundant leukocytes in normal blood are [x1].

Neutrophils

The least abundant leukocytes in normal blood are [x1].

Basophils

[x1] are fragments of megakaryocytes and are instrumental in blood clotting.

Platelets

The leukocytes known as [x1] have granules that stain red with Wright's stain and are responsible for killing parasitic worms.

Eosinophils

The formed elements known as [x1] are shaped like bi-concave discs and are responsible for carrying oxygen and carbon dioxide in the blood.
