1 a digoxin level
red or gray
3 chem profile
green or yellow
blue filled atleast 95% of the tube
5 when you need extra blood just in case another test is called for?
when your drawning a pt it is best to get whatever tubes you are able to draw i.e. you have an order for a CBC, CMP, SPE, and an ESR, this pt is about to have surgery so I would draw a purple, green, yellow, red, pink and a blue (if i am able to)(* but if not just a purple, green, yellow, and a blue*), just incase the doctor order a TYPE & SCREEN, PT/PTT, or something of the wall you will have the extra pink, red, and blue but in all fairness in this case your red top would be your extra if all of the above test where ordered
