Case Studies

  • Our laboratory was running an “in-house developed” fractionated 25-OH Vitamin D test on our LC/MSMS system. We were making our own standards and it was very labor intensive. We needed a precise but, economical solution. UTAK was able to manufacture a custom set of six controls that had been validated by a third party, which we could use for calibrators. They even were able to package them in vials that we supplied to use on our pipetting station so there was no need to transfer them for use by the staff.

  • We requested that UTAK prepare the majority of controls that we are using in our Toxicology department for drug confirmation testing, they have been extremely helpful in that regard. We currently have a special Tricyclic Antidepressant control containing Amitriptyline, Nortriptyline, Imipramine, Desipramine, Doxepin, and Nordoxepin. We also have two special opiate controls – one containing Morphine, Codeine, 6-MAM and Hydromorphone and the other containing Dihydrocodeine, Hydrocodone, and Oxycodone. Additionally, we have a special THC Glucuronide control at 11ng/mL. Every time we have requested a special control, UTAK has been great to work with - developing it, and verifying it and delivering it within a reasonable time frame.

  • I needed a Norepinephrine free urine control to extract calibration standards and QC samples from for a bioanalytical assay I was developing using ion-exchange SPE and HPLC-ECD detection. Norepinephrine is an endogenous compound and the techniques I used to degrade native Norepinephrine in porcine urine were not working to my satisfaction. Thankfully, SMx urine met my needs. By employing SMx urine, I was able to establish a 1 ng/mL lower limit of quantitation.

  • Personalized QC starts here. Your answers will help us deliver exactly what you need.
    Matrix samples allow you to screen the starting material, prior to manufacturing, for interference with your test method or analytes of interest that are not tested in our in house ELISA screen. Adding a matrix sample to the order typically adds 1-2 weeks to the manufacturing lead time and can increase the per vial price of the material. Matrix samples are required when the analytes of interest are endogenous to the human body, to determine a baseline reading prior to manufacturing.
    We manufacture and spike products gravimetrically; we do not test in-house to confirm concentration. We have been making products this way for over 40 years and are confident in our manufacturing accuracy. However, if you select this option, we will send this product to a 3rd party lab and provide a single run reference point confirming the concentration of the material. This process will extend the manufacturing lead time by 3-4 weeks. The actual cost each test will be included on your quote. We guarantee our products whether you select this service or not. If you have any issues with your material please contact us for support.
    If you select this option we will send you 1 vial of each level of this product after manufacturing completes, to test for approval prior to shipping the full order. Once you have completed the approval process, there will be an approximate lead time of 1-3 business days to receive your full order. There is no charge for this service. We guarantee our products and we will support you with any issues regardless of whether you request a validation sample or not.
