Sample Collection and Processing
- Draw minimum 1 mL (Pediatric) to 4 mL (Adult) of blood into 4-mL Sodium Heparin green top blood tubes.
- Busulfan degrades quickly at room temperature. Each sample should be kept in wet ice slurry or refrigerated at all time. Centrifuge them as soon as possible at 4 °C. Separate the plasma from each sample and transfer it to individual 4mL plastic tubes. Immediately freeze these plasma samples at -20 °C.
- All samples have to be labeled with patient name, Medical Record #, date and actual clock time of the blood draw. Two unique identifiers and clock times are REQUIRED or samples can be rejected.
- Samples must be shipped on a minimum of 3 kg of dry ice using an overnight carrier. Samples that arrived thawed will not be analyzed.
- A REQUISITION SHEET (for regimen of Oral Q6hr and IV Q6hr or IV Q6hr and IV Q24hr is required to be sent with the samples. Patient identifiers must be matched with those on the collected samples mentioned above. Also, our requisition serves as physician’s order and must be signed by the attending physician or designee/caregiver according to the College American Pathologists (CAP) requirement.
- We usually release pharmacokinetics results on the same day as receipt of the samples. Average sample run-time is approximately 3 hours.
- Sample processing is prioritized by time zone differences or next dose due time to maximize the advantage of dose adjustments.
- All results must be verbally delivered to attending physician, pharmacist, or caregiver who is a certified MD or PharmD. No exceptions.
- After the verbal report, a hardcopy can be faxed to designated number(s). Please click here for an example of our facsimile report.
