Nasopharyngeal swab

Silver Amplification technology

The immunochromatographic assay was designed based on silver halide photography to amplify the size of gold colloidal particles approximately a 100-fold, leading to the improvement of detection sensitivity. This offers a greater ability to detect even in small amounts of antigens.

How to use

* Refer to the Instruction for Use for official procedures.
