The primary reason for introducing new or modified bioanalytical assay is to add value to a clinical diagnostic laboratory. From a historical perspective, the main driving factors for these activities have been the need to enhance the quality of bioanalytical assay and meet the ever-increasing clinical demand. Additionally, taxing requirements on limited clinical and healthcare resources have increased the need to reduce assay-associated costs.
Selecting an ideal assay is critical in a clinical diagnostic laboratory. Besides, accuracy in biochemical analysis further increases the importance of reliable assay testing in clinical diagnosis. But what is biochemical analysis? Biochemical analysis focuses on detecting and evaluating carbohydrates, liquids, enzymes, protein and non-protein components, and other inorganic elements that must serve as an indicator for several biochemical reactions.
The current article aims to provide a broad overview of the role of assay testing in clinical diagnostics.
Bioanalytical methods and assay testing in clinical diagnostics
Products related to medical testing and clinical diagnostics are essential for diagnosing and treating patients. Often, doctors and healthcare professionals face challenges in evaluating a specific set of symptoms associated with a disease. These challenges can impact clinical diagnostic testing. If currently available tests can find it challenging to differentiate between causes, it may leave patients frustrated and delay diagnosis. Hence, assay testing in clinical diagnostics can help identify pathogens or biomarkers that may help in diagnosis and aid in developing therapeutics.
Assay testing in clinical diagnostics is used to study biological markers in diagnosis or monitor multiple risk factors. Laboratories and hospitals use assay testing to identify and study clinical samples containing target analytes. Diagnostic assay testing can determine the quantity, property, presence, or functional properties of different target entities, including drug compounds, organic samples, chemical elements, microbial pathogens, and cellular organisms. With a better understanding of biological targets, healthcare professionals can develop effective therapeutics for individual patients.
Diagnostic assay testing has a defined set of reagents, including the biological mixture and reagents needed to generate a chemical reaction. These reagents confirm the presence or absence of a target analyte and provide clinicians with a comprehensive picture of the target analyte’s biological profile. The quality of a clinical diagnostic assay depends on the reproducibility and robustness of the system signal and the type of signal measured in the assay. Some examples of different signal types are luminescence, fluorescence, absorbance, radioactivity, etc. By measuring these signals, clinicians and researchers can gain valuable data about the target specimen.

Molecular diagnostic assays are generally employed by researchers and clinicians to identify target analytes in a given sample matrix. These molecular diagnostic assays may contain multiplex diagnostic tests or syndromic panels. Clinicians utilize these molecular diagnostic assays to study patients having a particular condition, encompassing diverse fields such as infectious diseases, oncology, genetics, and pharmacogenomics.
Today, molecular diagnostic methods are becoming critical in infectious disease biology. These assays can help prevent the spread of the disease, proving to be a vital public health system. These assays provide accurate and rapid results about specific infectious targets and can help healthcare professionals make informed decisions. In conclusion, assay testing plays a significant role in clinical diagnostics.
