Johnson Test Papers Limited PH Indicator Strips 0-6 (ICN 1229)

Important Customer Notice Recall

Ref: 2021/1229 ICN Number: 1229

MHRA: 2021/003/019/601/007



  • Johnson Test Papers Limited has issued an urgent Field Safety Notice to recall a single lot number, 103CE29, of the pH Indicator strip. This is following discovery that the wrong indicator strip, namely 2-9 pH has been packaged in the pH-06 strips packaging.
  • Johnson Test Papers was made aware of this issue when a customer noticed the test pad was a different colour. The middle pad for the pH indicator strips 0-6 is blue whereas the middle pad for the pH indicator strips 2-9 is green.
  • The hazard of using pH 2-9 indicator strips with the pH0-6 printed scale is that the value read will not be accurate. Misinterpretation of pH may lead to a wrong clinical decision of nasogastric tube position in the stomach leading to additional clinical procedures or initiation of feeding while the feeding tube is not in the stomach.
