FAQ: How To Draw Blood From Picc Line?

PICC line Blood Draw Instructions

Central lines are IVs that allow medications to be given into large veins in the body or blood to be drawn for lab work. Flushing a central line requires saline flushes and alcohol pads, and the doctor may want to add heparin, an anticoagulant, depending on the line.

Can you draw blood from single lumen PICC line?

A single lumen PICC has one tubing and one cap on the end, and it can be used to draw blood if it is large enough.

Why can’t you draw blood from a PICC line?

Do you flush a PICC line before drawing blood?

When not in use or after any infusion or bolus injection, the PICC should be flushed once weekly with 10mls of 0.9% Sodium Chloride to maintain patency; there is no need to withdraw blood into the syringe prior to a routine saline flush (RCN 2010).

Can you draw blood from a TPN line?

Because TPN is lipid-rich and sticks to catheters, blood collection from the same lumen of a catheter used to administer the solution is best avoided. For most tests collected from adult TPN patients, stopping the infusion for 2 to 3 minutes prior to blood collection should suffice.

Can a phlebotomist draw blood from a PICC line?

You’ll need an alcohol pad or appropriate cleansing agent for the port, a tube holder, a needleless vacuum collection device, appropriate blood tubes, including a waste tube, patient labels, and saline flushes for each port if drawing blood from a peripherally inserted central catheter (PICC) line or central line.

What’s the difference between a central line and a PICC line?

PICC stands for “peripherally inserted central-line catheter,” and it’s a longer catheter that’s also placed in the upper arm. Its tip ends in the body’s largest vein, which is why it’s called a central line. A CVC is similar to a PICC line, but it’s placed in the chest or neck.

What happens if you don’t flush a PICC line?

Infection and catheter occlusion or rupture are risks associated with drawing blood specimens from a PICC if the PICC isn’t flushed properly afterward. However, for patients with severely compromised venous access, the PICC may be the only option for drawing blood specimens.

Can you flush a port without blood return?

If there is no blood return and you believe you are in the right place, try flushing with 2 or 3 ml of normal saline. If you are able to flush easily, pull back on the syringe plunger to see if there is still no blood return.

What lines can you draw blood from?

A central line (or central venous catheter) is similar to an intravenous (IV) line, but it is much longer and extends all the way up to a vein near or inside the heart, allowing the patient to receive medicine, fluids, blood, or nutrition, as well as draw blood.
