Laboratory Sample Submission Information

Overview

The Mycotic Diseases Branch offers clinical mycology testing of patient samples (i.e., specimens or isolates).

We can:

  • Accept samples only from state and local public health department laboratories and laboratories outside the United States.
  • Conduct laboratory testing for individual patients or for investigations of fungal disease outbreaks.
  • Help you select the most appropriate sample type or test type and assist with interpreting laboratory results.

Services we offer

Our laboratory offers identification of mold and yeast isolates, fungal serological testing, and whole genome sequencing.

How to send specimens

All submissions to the Mycotic Diseases Branch Laboratory must:

  1. Include an approved CDC submission document (Table 1).
  2. Meet the minimum acceptable criteria for the submission document and the specimen/isolate label (Table 2).

If the two criteria above are not met, testing may be delayed or the submission may be rejected.

At least two unique identifiers (IDs).
  • These IDs can be personally identifiable information (PII) but only if indicated acceptable by your CDC point of contact.
  • If PII is not indicated, do not include medical record numbers or other PII.
    • We suggest instead creating two unique IDs that are linked to, but distinct from patient information.
  • Both IDs on the submission document must match the IDs on the specimen/isolate label.
Collection date.
  • This should be the date of specimen collection, not the date of subculture or receipt from another institution.
State (if United States) or country (if international) of patient origin.

Please note:

  • Clearly label the outer packaging if the submission requires refrigeration.
  • CDC does not accept routine shipments on weekends or holidays.
