MediCheck Logo2 copy  |  Protein Residue Test

MediCheck is a quick and easy way to verify the cleanliness of washer disinfectors, dental tools, and surgical equipment in support of infection prevention and control. MediCheck detects any protein residues left on a surface after cleaning. By simply swabbing the area and activating the device, you release a reagent that turns color, providing a qualitative and semi-quantitative result of the protein levels on the surface: green means clean and purple means re-clean. The more protein present, the quicker the color change to purple and the darker the color. MediCheck quickly validates surface hygiene, allowing immediate corrective action to be taken when necessary.

The proof is in the color.

Green means clean, and purple means re-clean. Protecting your patients and ensuring tool hygiene has never been easier. The more protein in your sample, the deeper and dark the purple becomes. There's even a color chart printed on the label to help with interpretation and eliminate any guesswork.
