Candida auris Testing

Candida auris isolate submission guide

No cost for this testing.

  1. Organisms: All Candida auris isolates representing invasive (e.g., blood and Cerebral Spinal Fluid), non-invasive (e.g., urine, wound, and respiratory tract), and screening (e.g., an axilla/groin swab) sources*.
    • Clinical isolates from unusual Candida spp. (species other than C. albicans, C. parapsilosis, C. dubliniensis, C. lusitaniae, C. tropicalis, or C. krusei).
    • Clinical isolates that fit the criteria of an unusual Candida spp., as defined above, do not need to be submitted if the identifying laboratory uses matrix-assisted laser desorption ionization time of flight (MALDI-TOF) for speciation and confirmation of Candida spp.
    • New clinical isolates of C. auris from previously identified patients should still be sent to IDOHL for confirmation and subsequent antifungal susceptibility testing.
  2. Specimen type: Isolates. Pure viable culture on appropriate agar medium (Sabouraud-Dextrose, BHI, Mycosel) slant.
  3. One isolate per patient.
  4. Isolates should be submitted within three (3) business days of isolation per the IDOH Communicable Disease Rule 410-IAC 1-2.3-76.
  1. Appropriate agar medium slant in tube with screw-cap tightened and parafilmed or other similarly approved commercial transport medium.
  2. Shipping boxes/containers with appropriate shipping labels, available commercially.
  1. Properly label the culture tube with a minimum of patient's first/last legal name, date of birth, and date the organism was isolated.
    • A minimum of two (2) unique identifiers must be indicated on the isolate tube.
    • Unique identifiers must match what is entered into LimsNet.
  2. Check the expiration date on the tube to ensure the product is acceptable and will continue to be acceptable once received at the IDOH laboratory.
  3. Isolates should be shipped at ambient temperature as Category B UN3373, triple contained, in accordance with federal shipping regulations for diagnostic specimens.
  4. Complete the LimsNet submission form for Mycology (Candida) testing.
    LimsNet is available on the web at To sign up for LimsNet, or to ask a question, email the Help Desk at
