The ability to extract a broad range of different drugs from a biological matrix allows for the expedited analysis of a patient sample using LC-MS/MS. Typically small molecules are extracted from matrices like urine based on their polarities. A fast and reliable sample preparation method that could be implemented to extract drugs of different polarities from urine could be used as a screening tool to quickly identify the presence of illicit drugs in patient samples using LC-MS-MS.
This poster demonstrates the utility of supported liquid extraction for the extraction of over 30 different acidic, basic and neutral drugs in urine prior to LC-MS/MS.

The use of schedule I drugs for patient pain management therapy warrants constant monitoring of therapeutic levels in the patient. Screening patient urine samples for the free drugs is complicated by the metabolism process which converts the free drug to the -glucuronide form. Patient urine samples can be enzymatically hydrolyzed and extracted to detect the drugs using Supported Liquid Extraction (ISOLUTE SLE+) which offers an efficient alternative to traditional liquid-liquid extraction (LLE) for bioanalytical sample preparation. LOQs for recovered drugs ranged from 10 ng/mL to 0.5 ng/mL with recoveries above 80% and RSDs <10%

The use of schedule I drugs for patient pain management therapy warrants constant monitoring of therapeutic levels in the patient. Screening patient urine samples for the free drugs is complicated by the metabolism process which converts the free drug to the -glucuronide form. Patient urine samples can be enzymatically hydrolyzed to cleave glucuronide moiety and produce the free form of drug. The target analytes can them be extracted from the urine matrix using EVOLUTE CX solid phase extraction cartridges. LOQs range from 5 ng/mL to 0.5 ng/mL with recoveries above 80% and RSD <10%

Drug of abuse testing is typically conducted using urine specimens from patients being screened for illicit drug use. While collection of urine is considered a relatively non-invasive drug testing action, it is not convenient for law enforcement to do in the field. The ability to collect an oral fluid sample in the field can be considered non-evasive and simple to implement. Currently there are oral fluid collection kits (e.g. Immunalysis Quantisal™, Orasure Technologies Intercept®) that facilitate the collection in easy to follow protocols. Oral fluid samples collected using standard collection kits can be qualitatively and
quantitatively analyzed by LC-MS/MS, post extraction of the target analytes from the matrix. Drug analytes can be successfully extracted from oral fluid using Supported Liquid Extraction (ISOLUTE SLE+), which offers an efficient alternative to traditional liquid-liquid extraction (LLE). In this poster, we
demonstrate a new rapid and reliable sample preparation method to extract a broad suite of drugs (Figure 1) from neat oral fluid and buffered oral fluid matrices.

The screening of patient urine samples for basic drugs is typically performed following a lengthy sample preparation methodology that requires a time consuming dry down step.
A novel elution protocol coupled to the EVOLUTE EXPRESS advanced plate technology affords a fast sample preparation solution that follows a LOAD-WASH-ELUTE-ANALYZE strategy. Basic drugs are fortified into urine and extracted in 3 easy steps using EVOLUTE EXPRESS CX solid phase extraction in a 96-well plate format.
