- All Candida species except for confirmed C. albicans.
|
|---|
| Minimum Volume/Size Required | - At least one viable pure isolate per plate/slant
|
|---|
| Storage/Preservation Prior to Shipping | - Isolates may be shipped to Laboratory at ambient temperatures.
- Ensure that growth media used does not expire before use.

| Specimen Labeling | - At least two patient identifiers required on specimen (e.g., patient full name, date of birth, medical record number).
- Three patient identifiers are preferred.
- Patient identifiers on specimen label must exactly match identifiers on submission form. (e.g., abbreviated name on label and full name on form is not acceptable.)
