Carbapenemase gene panel

Carbapenemase-producing organisms

Last reviewed 2026-08-13

Public health significance

Gene plus organism is the public-health unit of analysis. A naked 'CRE detected' is not enough.

Specimen types

Isolate or rectal/perirectal screening swab as validated

Method

Multiplex NAA for blaKPC, blaNDM, blaOXA-48-like

CLIA / validation

High complexity. Validate each gene. Screening vs isolate claims are different intended uses.

Interpretation

Detected / Not detected per gene. Always attach the organism SNOMED when known.

Reflex / referral

Isolate submission to the AR Lab Network as required. AST still matters.

Quality control

Gene-specific positives. Watch for new alleles that the panel will miss.

Reportability

Many states require CPO reporting and isolate submission.

HL7 / ELR

One OBX per gene (85502-3, 85503-1, 85504-9 families) plus an organism OBX.
