bioanalyysin

Bioanalyysi is a Finnish term that translates to bioanalysis in English. Bioanalysis refers to the quantitative determination of organic chemical compounds (i.e., drugs, drug metabolites, biomarkers) in biological matrices such as blood, plasma, urine, and tissues. This field is crucial in various scientific disciplines, including pharmaceuticals, clinical diagnostics, and forensic science.

In the pharmaceutical industry, bioanalysis is essential for drug development. It helps determine how a drug is absorbed, distributed, metabolized, and excreted (ADME) in the body. This information is vital for understanding a drug's efficacy and safety, and for establishing appropriate dosage regimens. Regulatory agencies like the FDA and EMA require extensive bioanalytical data for drug approval.

Clinical diagnostics also heavily relies on bioanalysis. It is used to measure the levels of various analytes in biological samples to diagnose diseases, monitor treatment effectiveness, and screen for specific conditions. Examples include measuring glucose levels for diabetes management or enzyme levels to detect organ damage.

Forensic science employs bioanalysis for identifying and quantifying substances in biological samples, often in criminal investigations. This can include drug testing for impaired driving cases, toxicology studies, or identifying biological evidence at crime scenes. The accuracy and reliability of bioanalytical methods are paramount in these applications to ensure justice.

The process of bioanalysis typically involves sample preparation to isolate and purify the analyte of interest, followed by detection and quantification using sensitive analytical techniques such as liquid chromatography-mass spectrometry (LC-MS), gas chromatography-mass spectrometry (GC-MS), and immunoassays. The development and validation of these methods are critical to ensure their accuracy, precision, sensitivity, and specificity.
