Test Code FGEN Fungal Culture, Routine

Performing Laboratory

Mayo Clinic Laboratories in Rochester

Specimen Type

Varies


Ordering Guidance


Nocardia and the other aerobic actinomycetes are not fungi, therefore a fungal culture should not be ordered. However, these organisms grow well on mycobacterial medium. When infection with this group of organisms is suspected, order CTB / Mycobacteria and Nocardia Culture, Varies.



Shipping Instructions


Specimen should arrive within 24 hours of collection.



Necessary Information


Specimen source (anatomic body site) is required.



Specimen Required


Submit only 1 of the following specimens:

 

Preferred:

 

Specimen Type: Body fluid

Container/Tube: Sterile container

Specimen Volume: Entire collection

 

Specimen Type: Fresh tissue

Container/Tube: Sterile container

Specimen Volume: Pea size

Collection Instructions: Tissue should be placed in small amount of sterile saline or sterile water.

 

Acceptable:

 

Specimen Type: Bone marrow

Container/Tube: Sterile container, SPS/Isolator system, or green top (lithium or sodium heparin)

Specimen Volume: Entire collection

 

Specimen Type: Respiratory specimen

Container/Tube: Sterile container

Specimen Volume: Entire collection

 

Specimen Type: Urine

Container/Tube: Sterile container

Specimen Volume: 2 mL

Collection Instructions: Collect a random urine specimen.

 

Fresh tissue or body fluid are preferred over a swab specimen. Recovery of mycobacteria from swabs is generally very low yield. Only submit a swab specimen if tissue biopsy or fluid aspiration is not possible.

 

Specimen Type: Swab

Supplies: BD E-Swab (T853)

Sources: Dermal, ear, mouth, ocular, throat, or wound

Container/Tube: Sterile, screw-capped tube containing Liquid Amies Medium with flocked swab (eg, E-Swab)

Specimen Volume: 1 mL in swab container with swab

Collection Instructions:

1. Before collecting specimen, wipe away any excessive amount of secretion and discharge, if appropriate.

2. Obtain secretions or fluid from source with sterile flocked swab. Paranasal sinus collections must use a nasopharyngeal flocked swab.

3. Place flocked swab in sterile, screw-capped tube containing 1 mL of Liquid Amies Medium.

4. If smear and culture are requested or both a bacterial culture and fungal culture are requested, collect a second swab to maximize test sensitivity. Submit each swab in a separate sterile, screw-capped tube with 1 mL of Liquid Amies Medium.


Specimen Minimum Volume

Bone marrow or body fluid: 1 mL; Cerebrospinal fluid: 0.5 mL; Respiratory specimen: 1.5 mL; All other specimen types: See Specimen Required
