Question

When collecting blood for a complete blood count (CBC), which of the following is not true?

1) If clots are present, a new sample should be collected.
2) 2 ml of blood is sufficient for a CBC from any animal species.
3) The collection tube should be inverted 10-15 times before further processing to ensure the RBCs, WBCs, and platelets are evenly dispersed in the sample.
4) None of the above. A, B, and C are all true.

Answer 1

Statement 2 claiming that 2 ml of blood is sufficient for a CBC from any animal species is incorrect because the amount needed can vary by species and equipment.

Step-by-step explanation:

When collecting blood for a complete blood count (CBC), not all of the statements provided are true. While it is correct that if clots are present, a new sample should be collected, and the collection tube should be inverted 10-15 times to ensure the red blood cells (RBCs), white blood cells (WBCs), and platelets are evenly dispersed, statement 2 is not accurate. The amount of blood sufficient for a CBC can vary depending on the animal species and the testing equipment used. Thus, stating that 2 ml of blood is sufficient for a CBC from any animal species is incorrect.
