Sample Collection Media for Precise Volume Collection with High Analyte Recovery

Accurate diagnosis starts with the proper collection of a sample, as the pre-analytic stages of diagnostic testing can lead to erroneous results if not performed correctly. A precise volume uptake followed by a high analyte release combined with the removal of inhibitors ensures the consistency of diagnostics workflows.

Porous materials offer controlled pore sizes and structures, allowing for precise volume uptake as well as inhibitor removal crucial in sample collection. For challenging analytes, customized material solutions can reduce nonspecific binding. Integrating sample collection materials into direct sample-to-test devices eliminates sample loss via transfer steps to prepare a higher concentration of analyte for higher sensitivity.

In addition, sample sufficiency indicators can visually demonstrate when samples are ready to reduce user error in at-home settings. Optional integrated chemistry can simplify workflows by eliminating additional steps to help treat and normalize samples, such as incorporating cell lysis into the collection step or buffering in samples with wide variations of pH.
