When collecting specimens for a blood cell count, you would use a tube that contains?

  1. A clot activator

  2. A preservative

  3. An anticoagulant

  4. A nutrient medium

The correct answer is: An anticoagulant

An anticoagulant is used in blood cell counts in order to prevent clotting and maintain the blood cells in a liquid state. Option A, a clot activator, would promote clotting and interfere with the count. Option B, a preservative, is not necessary as the sample is typically used immediately. Option D, a nutrient medium, would not be suitable as it is designed to support the growth of microorganisms and not the preservation of blood cells.
