Whole blood, serum, plasma single drug assay kit, 50 ng/mL

In recent years, the demand for accurate and efficient drug concentration detection in biological samples has been rapidly growing across multiple scientific research fields, including pharmacology, toxicology, and clinical pharmacology. Researchers often need to quantify specific drug components in complex biological matrices to study drug metabolism pathways, evaluate drug efficacy, and assess potential toxicological effects—all of which rely on reliable bioanalytical tools.
Whole blood, serum, and plasma are the most commonly used biological samples for drug concentration analysis, as they directly reflect the in vivo drug exposure level. However, these matrices present significant challenges for detection: they contain a variety of interfering substances (such as proteins, lipids, and endogenous metabolites) that can affect the accuracy of test results. Additionally, many research scenarios require detecting drugs at low concentrations (often at the ng/mL level), which places high demands on the sensitivity and specificity of assay kits.
Traditional drug detection methods, such as high-performance liquid chromatography (HPLC) alone, often lack sufficient sensitivity for trace-level drug analysis and require complex sample pretreatment steps (e.g., liquid-liquid extraction or solid-phase extraction), which are time-consuming and labor-intensive. Immunoassay-based kits have emerged as a more efficient alternative, but not all kits on the market can balance sensitivity, ease of use, and compatibility with multiple sample types.
Against this backdrop, the Whole Blood, Serum, Plasma Single Drug Assay Kit (Cat.No: CD-00138) is developed to address the core needs of researchers. With a detection cutoff of 50 ng/mL, it is tailored to detect trace drug components in whole blood, serum, and plasma—filling the gap for tools that can handle multiple sample types while ensuring high sensitivity.
