Answer :
Final answer:
The collection tube for capillary puncture usually holds around 0.5 mL to 2 mL of blood. Blood is drawn into the tube via capillary action for medical tests. The exact volume can vary based on the design of the collection device and patient factors.
Explanation:
The collection tube for capillary puncture typically has a small volume of around 0.5 mL to 2 mL. Blood for medical analysis is collected via capillary action, as the blood is drawn into this small diameter tube. The blood is then often used for a variety of tests, many of which require only small volumes of blood. However, it's important to note that the volume of blood that can be collected via capillary puncture is limited compared to venous blood draw, and the specific volume can depend on factors like the specific design of the collection device and the patient's individual circulatory traits.
