Authors: Akos Zahar, Jeroen Neyt, Cesar H. Rocha, Thorsten Gehrke, Christian Lausmann, Julia Vasquez
RECOMMENDATION: Yes, there are several useful POC tests which can be added to the diagnostic workup of PJIs. A number of studies support the
usefulness and reliability of the leukocyte esterase (LE) test strip and the alpha-defensin lateral fl ow test kit. Diagnostic criteria for PJIs should be
updated and consider inclusion of these tests.
