Test Details
Methodology
Polymerase Chain Reaction (PCR)
Result Turnaround Time
2 - 3 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
This test is used to detect Candida auris colonization of the axilla and groin.
Limitations
A negative test does not rule out colonization with C. auris. Although the axilla and groin are the most common sites of C. auris colonization, other body sites may also be colonized. Results should be interpreted in conjunction with clinical findings and epidemiological risk for C. auris colonization.
Improperly collected samples may result in false negative results.
This test is intended for screening purposes only. It should not be used to diagnose C. auris infection.
This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.

Specimen Requirements
Specimen
Composite axilla and groin swab
Volume
One composite swab submitted in Liquid Amies (ESwab®)
Container
Liquid Amies Media (ESwab®)
Collection Instructions
A single swab is used to collect a combined (composite) sample from both the left and right axilla and the left and right groin. While collecting the sample, roll the swab tip over the skin several times to ensure adequate specimen collection. Place the swab into the ESwab® collection tube (containing Liquid Amies media) and submit promptly to the laboratory.
Stability Requirements
Temperature | Period |
|---|---|
Refrigerated | 14 days |
Frozen | 30 days |
Freeze/thaw cycles | Stable x2 |
Storage Instructions
Refrigerate.
Causes for Rejection
Improperly submitted specimens (specimen submitted without a swab; specimen not submitted using an ESwab® collection device; specimen with a clinical source other than axilla/groin; grossly leaking specimens; specimens received outside of stated stability or without required patient identifiers)
