What is Bioanalysis?
What is Bioanalysis?
Bioanalysis is a specialized branch of analytical chemistry that aims to quantify the concentration of a drug, metabolite, or biomarker in a biological matrix such as blood, serum, plasma, urine, or tissue samples.
For small molecules drugs, method development involves selecting an appropriate sample preparation technique to isolate the drug or metabolite of interest from the biological matrix.
For Biologics, the bioanalytical assays must be highly selective to avoid cross-reactivity with endogenous substances or other analytes in the sample matrix. We use an array of strategies starting from Ligand binding assays (LBAs) such as ELISA, LC-MS/MS, LC-HRMS, and hybrid LC-MS or immunoaffinity-LC-MS.
When Are Bioanalytical Studies Needed in Drug Development?
Bioanalytical studies are critical in any drug discovery and development program. Studies that require bioanalytical support include bioavailability (BA)/bioequivalence (BE), non-clinical pharmacokinetics (PK)/toxicokinetics (TK), anti-drug antibody assays (ADA), and biomarker evaluation. Guidelines for these studies have been outlined by the FDA, ICH, EMA, and other global regulatory bodies.
