AI Technical Summary

Technical Problem

Existing single-well immunochromatographic assay kits require complex pretreatment when processing different types of samples, which affects the accuracy of the assay and makes it difficult to meet the needs of multiple assays, increasing costs and reducing efficiency.

Method used

An immunochromatographic assay card with dual sample loading wells was designed, with pretreatment areas for whole blood samples and routine samples respectively. Whole blood samples are treated with a glass fiber filter layer and a hemolysis layer, eliminating the need for additional pretreatment. The card also features dual test lines and observation wells for easy result interpretation.

Benefits of technology

It enables direct testing of whole blood samples, reduces operational difficulty, minimizes errors, meets diverse testing needs, improves testing efficiency, and reduces the amount of reagent cards used.
