The CPL now has contracts with UPS and FedEx offering approximately 50% off overnight service. Due to slightly better pricing and no pickup charges when billed to our account, Fedex Standard Overnight is our preferred method of shipping, but if it is more convenient, you are welcome to use UPS Next Day Air Saver. The easiest way to ship using our account is for us to order you billable stamps. Please contact us (with Clinic Name, Address, Phone Number, and name of person we can send them to) and we will order them for you. The billable stamps are free to order and the minimum number is 10. They usually take 5-7 business days to arrive, so order before you are ready to send the sample. If you use our account to ship, we will add the charges to your invoice.

Please note: When serum is requested (see specific test requirements below), please draw in red top tube (no serum separator tubes due to binding of drug), allow time to clot, spin down, draw off and send just the serum. This provides the cleanest sample and therefore, the most accurate results.
Amikacin - $100 Single Sample; $125 Peak & Trough
Minimum Sample Required: 0.5ml Serum or Plasma (no serum separator tubes), ship in plastic tube because aminoglycosides bind to glass. Fasting recommended but not required. No ice needed. Peak sample: 1.5-2hrs post dose. Trough sample: Just prior to next dose (12hrs post on 12hr dosing) if goal is to assure concentrations are below that of safety. If your goal is also to calculate a disappearance half-life then collect 4-6hrs after peak sample. Run as received (2-3 day turnaround time). Method: Immunoassay
Benzodiazepines (Diazepam, Chlorazepate, etc.) - $50 Single Sample
*Qualitative Assay (Positive/Negative). Minimum Sample Required: 0.5ml Serum or Plasma (no serum separator tubes). Protect from light with aluminum foil. Fasting recommended but not required. No ice needed. Peak sample (recommended): 1hr post dose. Run as received (2-3 day turnaround time). Method: Immunoassay.
Bromide (Potassium or Sodium) - $38 Single Sample
Minimum Sample Required: 0.5ml Serum or Plasma (no serum separator tubes). Fasting recommended but not required. No ice needed.

If greater than 12 hour dosing interval, a 12hr trough may still be needed or concentrations may be non-detectable. Recommend peak and trough first time to establish half-life. Run Wednesday and Friday mornings. Sample must be received by day before to be included in run. Method: Immunoassay
Digoxin - $45 Single Sample; $70 Peak & Trough
