Cross infection screen

Clinical Indications
To screen for the following organisms:

  • multi-drug resistant coliforms
  • multi-drug resistant Acinetobacter baumanni
  • vancomycin-resistant enterococci (VRE)
  • carbapenemase-producing Enterobacteriaceae (CPE)

Sample Required
Swabs in Amies transport medium

Transport to the laboratory on the day of collection or refrigerate overnight

Turnaround Time
3 days


Samples may be referred to Public Health England for further investigation.

The OKN test used to detect carbapenemase-producing Enterobacteriaceae test is qualitative and cannot predict the quantity of antigens present in the sample. Clinical presentation and other test results must be taken into consideration to establish diagnosis.

A positive test does not rule out the possibility that other antibiotic resistance mechanisms may be present. (The test is able to detect OXA-48, KPC,NDM only)
