Bioanalytical assay development helps determine the design implications, limitations, favorable conditions, and suitability of a drug for the intended treatment. Before assay development and validation can be initiated, it is recommended to understand the physiochemical properties of the analyte. Bioanalytical assay development is considerably informed by the details on protein binding and in vivo/in vitro metabolism along with essential aspects of prior work on the method. Bioanalytical assays play a crucial role in the discovery and development of pharmaceutical products given their ability to discern purity, identity, performance, and potency of these compounds. Furthermore, the involved techniques allow reproducible and reliable quantitation of analytes in various biological matrices, such as plasma, urine, blood, or serum.
Assay validation is performed for the analysis of drugs, metabolites, and biomarkers to ensure that the test results are precise and accurate, and the generated data is reasonably robust in supporting drug development and other intended purposes. Several method characteristics play a significant role during each stage of assay development and validation, including specific chemistry of analyte, sample clean-up to analysis methodology, and desired method sensitivity. The selectivity and sensitivity of bioanalytical assays developed for drug and metabolite quantitation thoroughly impact the success of preclinical and clinical studies. Thus, careful sample preparation, HPLC column, and mobile phase selection, and choice of detector and quantitation method are critical during LC-MS assay development.
The purpose of assay development and validation is to find a suitable method applicable to a chosen analyte in a specific biological matrix. The analysis outcome might be inaccurate if the assay is not validated correctly and deemed unreliable. This assay inadequacy could be due to low sensitivity, selectivity, precision, accuracy or any other reason. Given the significance of this topic, the FDA has published guidance to provide guardrails around assay development and validation discussions. Generally, the assay can be used with full confidence to produce reliable data if the FDA method development guidance is followed and all its outlined criteria are met. Thus, assay development and validation are carried out with appropriate technology so that compliance with regulatory and scientific requirements can be achieved. Additionally, analytical information obtained from already existing bioanalytical assays may sometimes be effectively utilized.
In summary, bioanalytical method development and assay validation enable reliable quantitation of analytes and biomarkers in various biological matrices to test drug safety and efficacy. We understand your invaluable bioanalytical assay data is reproducible and dependable only if generated using fully validated methods and platforms by qualified scientists.

Bioanalytical assay development and qualification help determine the design implications, limitations, favorable conditions, and suitability of a drug for the intended treatment. Specifically, bioanalytical assays enable precise identification and quantitation of a compound in a biological matrix. Optimal assay development and validation involve numerous scientific and regulatory considerations, and several such methods help measure various aspects of a drug compound. We recommend understanding the analyte’s physicochemical properties ahead of starting assay development and validation. At NorthEast BioLab, we offer custom assay development and validation services for your proprietary or commercially available compound as per various regulatory guidance.
The primary intent of assay validation is to perform a regulated (GLP/GCP) study with reproducible and reliable results for sponsors. At NorthEast BioLab, we perform method validation to verify assay parameters such as precision, accuracy, selectivity, sensitivity, and stability throughout the bioanalytical testing process. We complete three/six independent validation runs over multiple days to estimate intra-day and inter-day accuracy and precision, as described in the assay validation FDA guideline white papers. All applicable experiments for reference standards and critical reagents, calibration curve, QCs, matrix effect, matrix suppression, extraction recovery, and carryover are covered as well. In-process stability experiments for bench-top, freeze-thaw cycles, and -70C stability in relevant matrices. Typically, a fully validated method is appropriate during preclinical and clinical development phases of the drug development process. NorthEast Biolab provides full assay method validation services according to FDA guidelines for both small and large molecules.
Robust bioanalytical assay development and validation are essential to accurate measurements of drugs, metabolites, and biomarkers in bioanalytical assays. Ahead of getting started, we do publication research to become familiar with drug compounds or biomarkers. For example, we must consider the nature and any relevant characteristics of the bioanalytical sample itself. Thus, the sample composition and expected concentration of the analyte constitute noteworthy criteria among several other factors. US FDA, ICH, and other regulatory agencies provide bioanalytical method development guidelines for setting up reliable bioanalytical assays. Generally, the key characteristics for the execution of an acceptable method are sensitivity selectivity, reproducibility, intra-day and inter-day precision and accuracy, dilutional integrity, matrix effects, and analyte stability under all sample storage, handling, and preparation conditions. Assay qualification demonstrates that an accepted method will provide meaningful data for the specific conditions, matrices, and samples intended for the procedure. Our veteran team of bioanalysis experts is equipped to handle full assay validation for small and large molecule according to FDA guidance.
For bioanalytical assays, the FDA, EMA, ICH, and other regulatory agencies provide assay development and validation guidelines outlining the required parameters for appropriate method validation and sample analysis. We evaluate parameters for sensitivity, selectivity, reproducibility, intra-day accuracy and precision, dilution integrity, matrix effect, and analyte recovery during bioanalytical testing. A full method validation study must be completed for any custom bioanalytical assay method that is new or developed based on the scientific publications. A fully validated method shows that it can determine the concentrations of analytes such as a drug, metabolite(s), or biomarkers reliably in a specific biological sample matrix from a particular species.
FDA has issued multiple guideline documents to inform the development and validation of bioanalytical assays used for nonclinical and clinical studies focused on pharmacokinetics, toxicokinetics, or biomarker data. FDA assay development guidelines apply to chromatographic assays (CCs) and ligand binding assays (LBAs) that quantitate the levels of drugs, metabolites, therapeutic proteins, and biomarkers in biological matrices such as blood, serum, plasma, urine, and a variety of tissues. Assay development and validation ensure that the data reliability by addressing certain key questions: Does the assay measure the intended analyte? What is the variability within these measurements? What range of measurements provides reliable data? How do sample collection, handling, and storage affect the data reliability for bioanalytical assay?
In assay validation there are specific parameters mentioned in bioanalytical assay validation FDA guidance. Typical method validation parameters to be considered are:

Bioanalytical testing is a sub-discipline of analytical chemistry. It covers the quantitative measurement of xenobiotics (drugs and their metabolites, and biological molecules in various locations or concentrations) and biotics (macromolecules, proteins, DNA, RNA, large molecule drugs, metabolites) in biological systems. Bioanalytical method development is the quantitative determination of drugs and metabolites in biological matrices such as blood, serum, plasma, urine, tissue, and skin samples as applied to toxicology, pharmacology, bioequivalence, pharmacokinetics, and bioavailability studies in animals or humans. Immunogenicity tests are bioanalytical methods that target anti product antibodies in serum or plasma. Bioanalytical assay qualification is not intended to elucidate quality parameters (e.g., identity, purity) of a biotech product, instead bioanalytical analysis determines the quantity of a drug or the presence of induced antibodies in biological samples by using different bioanalytical techniques.
Bioanalytical assays focused on pharmacokinetics, bioavailability, toxicokinetics, immunogenicity, or biomarker testing play a crucial role in the discovery and development of drug products. We recommend understanding the physicochemical properties of the analyte before assay development and validation.
