Final answer:
After drawing a blood specimen for an electrolyte profile, the next step is to label the tube and then centrifuge the sample.
Step-by-step explanation:
After drawing a blood specimen for an electrolyte profile, the next step is to label the tube. This is done to ensure proper identification of the sample. Once the tube is labeled, the sample is then centrifuged. Centrifugation separates the blood into its components - the blood cells and platelets are separated from the liquid component, which is called plasma.
