Penicillamine challenge

The penicillamine challenge is a 48 hour test that is done to check for Wilson’s disease. Wilson’s disease is a rare, inherited condition in which the body cannot handle copper correctly, and needs medication to remove the excess copper from the body.

Your consultant will discuss the test results with you once they are available.

If you have been asked to do this test at home, it would be best to do it over a weekend as it is very important that all of your child’s wee can be collected.

To do the test you will need

  • 2 large wee collection containers
  • 2 lab forms for urinary penicillamine challenge
  • 2 doses of Penicillamine 500mg

All of these will be provided to you by the Sheffield Children’s Hospital.

Day 1

Day 1 uses wee bottle number 1. Do not collect your child’s first wee (for example 8am on Saturday).

When you child needs their second wee of the day, collect you child’s wee in bottle number 1. Write start time and date on the label.

You must now collect all of the wee that your child passes for the next 24 hours in this same bottle.

Day 2

Collect your child’s first wee of the day in wee bottle number 1 (for example 8am on Sunday). Write the end time and date on the label.

The rest of day 2 uses bottle number 2.

For the next 24 hours, collect your child’s wee in bottle number 2. Write the start time and date on the label.

Give the second dose of 500mgs of Penicillamine 12 hours after the first dose (for example at 9pm).

Continue to collect wee in sample bottle 2.

Day 3

Collect your child’s first wee of the day in wee bottle number 2 (for example 7am on Monday). Write the end time and date on the label.

Make sure both wee bottles are clearly labelled with your child’s details, and the start and finish time of the wee collections for each bottle. Both wee bottles and lab forms should be taken straight to Sheffield Children’s Hospital and handed in at Clinical Chemistry (open 9am till 5pm, Monday till Friday).
