Abstract

The invention relates to a serum or plasma sample diluent and application thereof. Particularly, the serum or plasma sample diluent comprises a buffer solution (a), albumin (b) with content of 10-100g / L, alkaline chloride (c) and an optional emulsifier (d), wherein the pH value of the diluent is 6.0-8.0. Compared with the existing human negative mixed serum or plasma and calf serum diluent, the diluent provided by the invention has the characteristics of precise and accurate detection result and long-time stable preservation. The invention also discloses a detection kit containing the diluent and application of the diluent in immunoassay.

Description

technical field

[0001] The invention relates to the technical field of biological sample detection, in particular to a serum or plasma sample diluent and its application. Background technique

[0002] At present, the new type of automatic immune analyzer can quantitatively determine the presence of serum or plasma samples separately under the condition of no separation due to its simple operation, high degree of automation, fast detection speed, good repeatability, and high precision. Dozens of trace proteins with clinical significance. However, due to methodological limitations (such as the narrow detection linear range of automatic immune analyzers) and biological differences (high concentration of specific proteins in the test samples), many immunological indicators in clinical tests make the test results often Beyond the upper limit of the linear range, a certain proportion of dilution is required to obtain accurate detection results. The automatic immune analyzer dete...
