Do not touch phlebotomy site after cleansing to prevent false positive culture growth. Use a syringe or butterfly to collect 1-5 mL of blood. Inject blood into the alchohol-cleaned MycoF/Lytic bottle. 
Container:

Myco/F Lytic  bottle (red cap) 
Minimum Volume:

3 mL is the minimum volume for optimal recovery.
Storage/Transport:

Room temperature; Transport to Microbiology Lab ASAP
Stability:

Transport to Microbiology Lab ASAP
Causes for Rejection:

Mislabeled, Under-labeled, or improper transport/ collection.

Specimens must be labeled. Loose labels placed in the bag or outside of the bag will not be accepted and will be considered under-labeled. 
Specimen Preparation:

The specimen must be collected using sterile technique to reduce the chance of contamination. The range of blood volume for optimum recovery is 3-5 mL. Prior to inoculation, bottles should be examined for evidence of contamination such as cloudiness, bulging or depressed septum, or leakage. 
Methodology:

Bottles are continuously agitated and incubated in the BD BACTEC FX. Decreases in oxygen due to microorganism metabolism and growth will trigger positive bottle alert. 
Performed:

Clinical Microbiology
Turnaround Time:

6 weeks
Reference Range:

No Fungi Isolated. 
CPT 4 Code:

When ordering tests for which Medicare or Medicaid reimbursement will be sought, physicians should only order tests that are medically necessary for the diagnosis or treatment of the patient. Components of the organ or disease panels may be ordered individually. The diagnostic information must substantiate all tests ordered and must be in the form of an ICD-10 code or its verbal equivalent.
