Pain management therapy warrants constant monitoring of therapeutic levels of prescribed drug levels in patient urine samples. The number of samples being submitted for analysis has increased dramatically in the last 10 years with improvements in high throughput automated screening capabilities. Patient samples analysis is complicated by the need for an effective sample preparation methodology that can extract target analytes from complex matrices with good efficiency. Further complicating the process is the need to enzymatically hydrolyse the glucoronidated metabolites prior to extraction from the urine matrix. A fully automated sample preparation process using a TECAN Freedom EVO® 100 was designed to incorporate both the enzymatic hydrolysis and subsequent sample preparation assay as one continuous workflow. Supported Liquid Extraction (ISOLUTE SLE+) which offers an efficient alternative to traditional liquid-liquid extraction (LLE) and solid phase extraction (SPE) techniques was used to extract a suite of pain management drugs from spiked urine samples. A recovery and quantitation assay was run on the TECAN Freedom EVO® 100 using mock patient samples to demonstrate utility of automation process.

This report details a “load, wash, elute” weak cation exchange solid phase extraction procedure amenable to both plasma and urine samples. The extracts are subsequently injected into an LC-MS/MS system. The preliminary sample preparation method was developed at the Biotage US Applications lab (Charlotte, NC).The method was then transferred to Ionics (Bolton, ON, Canada) to facilitate the nmole/L measurements of the selected biomarkers by laminar flow tandem mass spectrometry. The SPE-LC-ESIMS/ MS method parameters were first optimized using pooled mixed gender plasma. A set of patient samples (n=32) was later supplied by the Mayo Clinic (Rochester, MN) that had previously been analyzed by a validated referee method. The population represented measured values across a range of clinical relevance. AACC 2014

The use of LC/MS analysis in the clinical lab has increased exponentially over the last 10 years. Modern mass spectrometers are extremely sensitive allowing low level detection of many target analytes. However, this sensitivity can come at a price, in that levels of contamination not previously detected with less sensitive instruments can now have larger impact on analysis. The complexity of common matrices such as plasma/serum and urine while presenting different challenges can have a marked influence on method performance. As a result sample preparation is an extremely important part of the process in order to provide robust methods. This seminar focuses on some of the method development challenges our lab faced when looking at two clinical assays: Endogenous steroid hormone extraction from serum, and catecholamine extraction from plasma and urine. Particular emphasis is placed on the various sample preparation options we looked at for the extraction of these analytes. During optimization of the extraction process we investigated analyte recovery, co-extractable matrix components, HPLC column degradation, calibration curve performance and limits of quantitation.

This application note describes the extraction of 96 licit and illicit drugs of abuse from urine prior to UPLC-MS/MS analysis using EVOLUTE® HYDRO CX 96-well plates. EVOLUTE® HYDRO CX plates offer an efficient way to perform hydrolysis in the well of the extraction plate. This method provides high analyte recovery, reduced extraction time due to the elimination of a sample transfer step as well as the elimination of the column conditioning and equilibration steps, and a reduced risk for sample carryover or cross-contamination due to the elimination of the sample transfer step.

Most drugs, both licit and illicit, are excreted in urine as glucuronide conjugates. Hydrolysis using beta-glucuronidase converts the glucuronidated metabolites back to their “free” or non-conjugated form, increasing sensitivity for LC-MS/MS analysis. Hydrolysis using red abalone, abalone, and recombinant beta-glucuronidase enzymes was evaluated using an in-well hydrolysis plate to determine which provided the most efficient hydrolysis of glucuronide metabolites without affecting overall recovery of nonconjugated compounds. A glucuronide control containing 8 glucuronide compounds was used to determine the extent of hydrolysis that occurred. A non-conjugated control containing 96 licit and illicit drugs of abuse was evaluated to determine if signal suppression occurred as a result of enzyme hydrolysis. ASMS 2017

This poster presents a method for detection of approximately 100 drugs and metabolites in urine using mixed-mode polymeric cation exchange solid phase extraction (SPE). Four different glucuronidase enzymes and several incubation times and temperatures were evaluated to determine optimum hydrolysis conditions for seven commonly detected glucuronide metabolites. Samples were subjected to offline hydrolysis and SPE (EVOLUTE® EXPRESS CX, Biotage, Charlotte, NC) and results compared to an SPE plate that incorporates in-well hydrolysis (EVOLUTE HYDRO CX, Biotage).

Endogenous phospholipids present in biological fluids are a major problem in LCMS/ MS analysis as they are often very difficult to remove during sample preparation. When phospholipids are not removed, they retain very strongly on reversed phase analytical columns. If high organic (end of run) washes are not incorporated into the LC methods these matrix components may elute in subsequent analyses causing regions of suppression/enhancement leading to inaccurate quantitation. This poster evaluates the use of polymer-based solid phase extraction (SPE) sorbents, incorporating hydrophobic and various mixedmode retention mechanisms to address the problems associated with phospholipid removal.
