Check with Reference Lab staff for collection tubes and times

Specimen Type: Plasma Na Heparin Specimen Required: Four plasma specimens with different draw times (keep all specimens under 1 order) and a completed Busulfan Information: Mail-In Specimen Instructions (T559) are required. Collection Container/Tube: Green top (sodium heparin) Submission Container/Tube: Plastic vials Specimen Volume: 1 mL Collection Instructions: 1. The first specimen should be drawn immediately after termination of intravenous infusion of 0.8 mg/kg busulfan. 2. Additional specimens should also be drawn at 1 hour, 2 hours, and 4 hours after termination of infusion. 3. Label each specimen appropriately (exact time of draw). 4. Busulfan degrades quickly at room temperature. Each specimen should be kept in wet ice slurry or refrigerated at 4 degrees C. Specimen should be centrifuged as soon as possible after collection. Separate the plasma from each specimen and transfer it to individual 5-mL plastic tubes. Immediately freeze these plasma specimens at -20 degrees C. Forms: Busulfan Information: Mail-In Specimen Instructions (T559) in Special Instructions Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected: 0.25 mL Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected: Hemolysis: Mild OK; Gross OK Lipemia: Mild OK; Gross OK Icterus: Mild OK; Gross OK Other: Serum gel tube Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included. Specimen Type Temperature Time: Plasma Na Heparin Frozen (preferred): 28 days Refrigerated: 72 hours
