Surface Hygiene Test Card
Brand: FSTest
2–10 mins Rapid Readout Time | 20 µg Protein Detection Limit | 50 Cards Complete Kit Pack | 18 Months Shelf Life (4–10°C) |
The FSTest Surface Hygiene Test Card is a paper-based testing sensor designed for the rapid colorimetric screening of protein residues on tableware, food processing equipment, and environmental surfaces.
Protein is a primary hotbed for bacterial propagation and a crucial structural component of microbial cells. By detecting trace protein organic soils remaining after cleaning, this kit provides food processors, catering facilities, and health inspectors with an immediate, visual indicator of sanitation efficacy, delivering accurate pass/fail determinations without requiring complex equipment or ATP luminometers.
Rapid Visual Colorimetric Readout: Yields clear color changes in 2 minutes for personnel hand testing or 10 minutes for equipment surface testing.
High Sensitivity Threshold: Reliably detects protein residue down to 20 µg, catching hidden organic soil before microbial blooms occur.
Broad Environmental Application: Suitable for personnel hand hygiene, food contact surfaces, catering kitchen utensils, and public environment surfaces.
Complete Ready-to-Use Kit: Packaged with 50 test cards, moisture solution, and chromogenic reagent for convenient field deployment.

Optimized for sanitation monitoring across diverse public and industrial touchpoints:
STEP 1 Moisten Surface Add 2 drops of moisture solution onto the target test surface (10×10 cm area). Uncover the film on a new test card. | STEP 2 Wipe & Sample Gently wipe the 10×10 cm sampling area with the round tablet side of the card in a back-and-forth motion several times. | STEP 3 Add Reagent Place test card on a flat bench with the round tablet face up. Add 1 drop of chromogenic agent directly onto the tablet. | STEP 4 Read Results At 15–25°C, compare card color with colorimetric scale after 2 min (hand testing) or 10 min (surface testing). |
Clean (Green): Reagent maintains light green hue. Surface or hands are free of significant protein residue.
Caution (Olive / Dark Green): Suggests a potential trend of declining cleanliness; additional attention should be given to cleaning during the next inspection.
Unclean (Light Purple): Distinct purple hue indicates moderate protein residue; re-cleaning is required.
Very Unclean (Deep Purple): Strong purple reaction signals heavy organic contamination; thorough sanitation and re-auditing are mandatory.
Adhere to strict operational parameters to ensure maximum screening accuracy:
Avoid Manual Contact: Do not touch the round tablet with fingers when uncovering the film to prevent false positive contamination from skin proteins.
Material Compatibility Note: Wooden and bamboo chopsticks interfere with this assay method and affect accuracy; strictly avoid using this kit on wooden or bamboo utensils.
Hand Testing Safety: Apply moisture solution to hands, complete sampling quickly, and then rinse hands thoroughly with clean water. Do not apply chromogenic reagent directly to skin.
Kit Components Included: 50 Test cards, Moisture solution (7 mL) x1, Chromogenic reagent (3 mL) x1, User Manual.
Required Equipment (Not Provided): Timer and clean water (for rinsing hands after testing).
