How to get a fluid sample from the PD catheter for a sterile culture
This is to check for germs or possible infection.
Supplies:
- Masks
- Blue pad (Chux)
- Alcavis
- Sterile 4x4 gauze – 4 packs
- Effluent bag
- Minicap caps (2)
- Hand sanitizer

- Ensure doors and windows are closed and fans are off.
- Access the PD catheter (remove it from the belt).
- Open two packages of 4 x 4 gauze but do not touch the gauze yet.
- Pour or spray Alcavis onto both gauze.
- Open Minicap to have it ready.
- Place blue pad under catheter.
- Gel hands and put on gloves.
- Pick up one saturated gauze. Scrub the end of the transfer set with Alcavis soaked gauze for 1 minute and then use the other Alcavis soaked gauze and wrap the catheter end for 1 minute.
- Do hand hygiene and put on new gloves.
- Hold the transfer set and remove the Minicap.
- Attach the effluent sample bag to the PD catheter and open the twist clamp. Be careful not to contaminate.
- Allow at least 50 mL to drain into the bag or at least until the bag gets half filled.
- Close the twist clamp on the transfer set and close the clamp on the effluent bag.
- Do hand hygiene and put on new gloves.
- Open 2 new packages of gauze.
- Pour or spray Alcavis on both pieces of gauze. Scrub PD catheter for 1 minute with one saturated gauze. Take the other saturated gauze and wrap the catheter end for 1 minute.
- Do hand hygiene and put on new gloves.
- Disconnect the effluent bag, put a new Minicap on the effluent bag.
- Place the new Minicap on the end of the transfer set.
- Write your child’s name on the effluent bag label and take it to the designated lab.
How to get a fluid sample from the Y sample port line for a sterile culture
This is to check for germs or possible infection.
Supplies:
- Gloves
- Masks
- Sterile specimen cup
Follow these steps:
To get a fluid sample your child must be in initial drain, the fluid appears to be cloudy during the initial drain, and your child must have had a dwell of at least 2 hours before going to the drain part of the cycle.
- Once in the drain, press “STOP.”
- Gather supplies.
- Put on a mask.
- Wash or gel your hands.
- Put on gloves.
- Open a sterile specimen cup and set the lid down with the inside facing up.
- Grab the pigtail port on the drain line.
- Fold the drain line below the pigtail port into the palm of your hand.
- Remove the cap on the pigtail port.
- Hold the port over the top of the specimen cup without touching it to the inside of the cup.
- With your other hand, press “GO” on the cycler.
- Let the fluid drain into the cup, pulsate once.
- Press “STOP,” clamp the drain line pigtail port and let go of the drain line.
- Press “GO” to resume therapy.
- Put the lid on top of the specimen cup.
- Write your child’s name on the label and take it to the designated lab.
How to get a fluid sample from the drain bag for a non-sterile culture
This is to check for adequacy (how well your child is dialyzing) and to see if the PD prescription is providing enough clearance for fluids and urea.
Supplies:
- Sterile specimen cups (1 for each drain bag plus 1 extra)
- Gloves
- Drain bag(s) from dialysis
Follow these steps:
- Gather supplies. Collect sample at the end of dialysis cycle.
- Remove the lid from the specimen cup to have it ready.
- Put on gloves.
- Agitate the solution in the drain bag.
- Open the access/drain port clamp (the larger clamp) and drain into the specimen cup until the cup is about ½ full, then re-clamp.
- Place the lid on specimen cup and tighten securely.
- Bring the specimen cup to your child’s clinic visit and give to your nurse. If submitting to your local lab, please label specimen cup.
If you have 2 drain bags:
You will need 3 specimen cups. 1 specimen cup for each drain bag and a 3rd cup to combine the samples from each of the drain bags. The 3rd cup should be filled half full of equal parts from each drain bag.
