Sample prep – the final frontier in biomarker testing
Biomarker tests have become an important tool in clinical diagnostics. The PSA test evaluates the risk for prostate cancer, and inflammatory and myocardial panels save lives when performed fast enough. Still biomarkers, especially protein biomarkers, are not yet used to their full potential. While novel approaches employ mass spectrometry instead of immunoassay detection, one bottleneck remains: the need for robust, fast, and efficient sample preparation.
