How much blood fills a vile?

A blood vile is a small container used to collect and store blood samples for medical testing. The amount of blood that fills a vile depends on the size of the vile. For example, a standard blood vile used in most clinical laboratories has a capacity of 5 milliliters (mL) or 0.17 ounces (oz). However, there are also larger viles available that can hold up to 10 mL or 0.34 oz of blood.
