HygieScan

What the scan does

• Reads one photo of one surface and reports four readings: microbial, dust, fungi and dirt
• Amplifies the photo so faint marks, residue and texture are easier to see, and marks the spots it judged
• Ranks the four readings from highest to lowest concentration, color-coded Clean through Severe
• Checks each reading against an acceptable standard for that surface and gives a meets / below verdict
• Rates how much the result can be trusted, from the photo quality and how visible the evidence was

Sees clearly

• Dust and lint that has actually settled on a surface
• Dirt, smears, splashes, food residue and stains
• Mold or mildew patches, fuzzy or powdery growth, and darkened grout
• Standing water, damp patches and a slimy sheen
• Insects or other organisms large enough to see

Can only estimate

• Microbial residue and biofilm — judged from moisture, residue and the kind of surface, never seen
• Harmful bacteria risk — read from signs that favour germs (damp, slime, food residue, stained grout), not from the germs themselves
• The size of a concentration — the numbers rank one surface against another, they are not lab measurements
• The acceptable standard — written by AI for the surface type, not an official or legal limit
• Whether a surface was clean before the photo was taken

Cannot see at all

• Bacteria, viruses and individual microbes, or which species are present — nothing is named unless it is visible to the naked eye
• Germs that are present but not yet visible
• Allergens, pesticides and chemical residues
• Contamination inside porous material, under liquid, or in seams and joints
• Whether a surface is safe to eat or drink from
