JM103 and JM105 Jaundice Meters – risk of misinterpretation of measurement in hyperbilirubinemia cases.

Draeger Medical Systems – misinterpretation of display may cause delay of treatment of neonatal jaundice.


  • Identify any JM103 and JM105 devices in your organisation.
  • Complete the “Confirmation of Receipt” form and the “Label Address Confirmation” form sent to you with the Safety Notice and return it to the manufacturer so that the warning stickers can be sent to you.
  • Apply the warning stickers to the devices.
  • Ensure there are systems in place so that users are trained to follow the Instructions for Use supplement (“Sample Usage Protocol Template”) in the Field Safety Notices for the JM103 and JM105.
  • If you possess JM105 devices, the manufacturer will contact you to arrange a firmware upgrade, once available, to improve the out-of-range error message. It should be installed on all JM105 devices and will be free-of-charge. It is therefore essential that you provide the manufacturer with your contact details.

Deadlines for actions

Actions underway: 25 June 2018

Actions complete: 06 August 2018

Medical Device Safety Officers (in England)

Ask the manufacturer to add you to their distribution list for field safety notices (FSNs). This is to help with reconciliation.


If your organisation receives an FSN from a manufacturer, always act on it. Do not wait for a communication from MHRA.

Problem / Background

In response to measuring values of bilirubin greater than 340 µmol/l or 20.0 mg/dl, the JM103 will display a flashing “- - -“error message whilst the JM105 will display a flashing “- 0 -“ error message. Misinterpretation of these messages has led to delay of treatment for jaundice in neonates. The manufacturer is supplying information labels to apply to these devices to clarify the meaning of these error messages.

The manufacturer will make a firmware upgrade available for JM105 devices that will allow the user to set the error message displayed in these circumstances to “>340 µmol/l” or “>20 mg/dl” or “- 0 -“. Organisations with JM105 devices will be contacted by the manufacturer via a Field Safety Notice to offer this upgrade which will be free of charge for all devices. The MHRA advises that this update is applied and option “- 0 -“ is not used.
