How to Use – Simple Workflow

1.  Sample Preparation
   Ensure milk sample is at 20–40°C and fully homogeneous.
   For powdered milk: dissolve at 1:9 ratio (e.g., 1g in 9mL distilled water).
   
   
2. Microwell Step
   Pipette 150μL of milk into a microwell.
   Mix gently and incubate for 3 minutes.
   
   
3. Strip Reaction
   Insert the test strip into the microwell.
   Wait for 7 minutes, then interpret results.
   
   
4. Result Interpretation
   T-lines (T1–T4): presence or lightness indicates the respective antibiotic residue.
   C-line: must appear to validate the test.
   T1: CAP  | T2: Streptomycins | T3: Tetracyclines | T4: β-Lactams
