Can you draw blood from a CVAD?
Have you ever looked at your patient’s labs and think “there is no way these labs are correct”? When drawing blood from a Central Venous Access Device (CVAD) you could inadvertently contaminate the blood sample with IV fluids and medications. This contamination causes extra work, such as the nurse having to draw the labs again, patients having more blood drawn and lab having to run the test again. This quick tip sheet is to remind us about the proper procedure to draw labs from a CVAD while avoiding contamination.

This tube is then discarded into the biohazard receptacle. The next step is to draw the blood sample into a sodium citrate collection tube which must be filled to the proper level (filled to complete vacuum volume) and is then gently inverted to mix.

Why did the order of draw change?
Whereas glass is a natural clot activator, plastic is not. So in order for blood to clot in safer plastic tubes, manufacturers coat the inside of the tube with a substance to facilitate clotting, like silica particles. However, if the tube following the clot activator tube remained the coag tube, as was the recommended order prior to 2003, carryover threatens the coag results. With the consensus of all major U.S. tube manufacturers, CLSI issued one single change in the order of draw when the venipuncture standard was revised in 2003: serum tubes that used to precede the blue-stopper coag tube were relocated to follow coag tubes. This change was only possible because a myth about tissue thromboplastin was disproved.
