What precautions should be taken when handling a blood specimen for a blood smear?

• Wear gloves, use a clean needle, label specimen correctly, and dispose of materials properly.

• Handle specimen with bare hands

• Reuse needles for multiple specimens

What is the role of anticoagulants in preserving blood specimens for hematology tests?

• Anticoagulants prevent blood clotting and maintain blood in a liquid state for hematology tests.

• Anticoagulants have no effect on blood preservation for hematology tests.

• Anticoagulants cause blood to coagulate quickly in hematology tests.

• Anticoagulants promote blood clotting for hematology tests.

How should a blood specimen be transported to the laboratory for testing?
