Reporting Name
Fungal Culture, BloodUseful For
Diagnosis and treatment of the etiologic agents of fungemia
Performing Laboratory
Mayo Clinic Laboratories in Rochester
Specimen Type
Whole bloodSpecimen Required
Container/Tube:
Preferred: Green top (sodium or lithium heparin)
Acceptable: SPS
Specimen Volume: 4 mL
Pediatric Volume: 3 mL
Collection Instructions:
1. Send whole blood specimen in original tube. Do not aliquot.
2. SPS tubes are acceptable, but not preferred.
Note: SPS tubes must be clearly labeled as SPS. If label is obscured, sample may be cancelled, as ACD (also yellow top) is not an acceptable tube type.
Specimen Minimum Volume
Adults: 3 mL
Pediatrics: 1 mL
