Sample Type

BTS covers a wide range of biological sample-types:
• Serum
• Plasma
• Cell Culture Supernates
• Cell Culture Lysates
• Urine
• Human Saliva
• Human Breast Milk
*Other sample types are available upon evaluation.

Sample Validation

Custom sample type evaluation is available if your desired assay has not yet been validated for your unique sample type. Typical evaluations include:
•      Spike and recovery to identify matrix interference
•      Linearity of sample dilution
•      Inter-assay precision & reproducibility (between different plates)
•      Intra-assay precision & reproducibility (within a plate)


Immediately upon receipt at BTS, samples are placed at the appropriate storage temperature and tracked using LabVantage® LIMS.
•  Sample chain of custody includes complete end-to-end traceability for a complete audit trail.
•  Sample storage options: -70◦C, -20◦C, 4◦C and room temperature.
*Other sample types are available upon evaluation.

Custom Services


The Biomarker Testing Service laboratory operates under the R&D Systems corporate Quality Management System, which is ISO 9001:2008 and ISO 13485:2003 certified. Additional quality assurance is provided by an independent QA group that evaluates equipment, personnel, standard operating procedures, and study compliance.

Quality Management Systems


Biomarker Testing Service applies the latest in technology with LabVantage®, LIMS a laboratory information management system that is 21 CFR Part 11/Annex 11 compliant. LabVantage® manages samples with end-to-end traceability and full instrument integration. Ensure precision with Hamilton Robotics, a fully automated liquid handling system from start to finish for high-throughput and integrated sample storage.


This project was very successful technically and yielded a robust data set that met current requirements as well as provided a new tool for future use, all delivered well within my project timelines. This was due in large part to the excellent communication and impressive initiative taken by the scientists and project manager who used R&D Systems’ extensive knowledge to find the best solution to my requirements.”
