Final answer:
A phlebotomist should transport blood samples using a specimen collection tray to ensure sample integrity. After blood is drawn, it is left for about an hour to allow the blood to clot and serum to separate, which is essential for many blood tests. The correct option is c. in a lockable container.
Step-by-step explanation:
The question pertains to the correct method for a phlebotomist to transport blood samples to the laboratory for analysis. The best practice for transporting blood samples is to use a lockable container.
This method ensures that the blood is carried safely, remains upright, and is protected from jostling or temperature extremes, which could affect the integrity of the sample. It is important to note that blood samples should not be stored in the trunk of a car, exposed to direct air conditioning, or in an unsecured fashion.
After a blood sample is collected, typically in a glass tube, it is left to rest so that the blood can clot and the serum can separate. This serum is essential for various blood tests. It is during this resting period, usually around an hour, that the serum forms.
