Pyrethroid Rapid Test Kit
Brand: FSTest
5–8 mins Rapid Readout Time | 0.5–2 mg/kg Target Multi-LOD | 10 Tests Complete Kit Pack | 18 Months Shelf Life (4–30°C) |
The FSTest Pyrethroid Rapid Test Kit is a professional-grade, rapid screening tool engineered for the qualitative detection of pyrethroid insecticide residues in fresh fruits and vegetables.
Pyrethroids, including Lambda-Cyhalothrin, Cyhalothrin, and Deltamethrin, are among the most widely monitored active ingredients in global agricultural surveillance. By eliminating the immediate necessity for complex, expensive laboratory infrastructure (such as HPLC or GC-MS), this field-ready assay simplifies sample extraction into a room-temperature workflow, delivering reliable visual results within 5 to 8 minutes for agricultural growers, fresh food exporters, and corporate quality compliance screening programs.
High-Speed Field Turnaround: Complete the entire assay workflow and achieve highly reliable visual result readouts within just 5 to 8 minutes post-preparation.
Target Multi-Analyte Detection Limits: Specifically calibrated to detect major pyrethroid compounds at targeted regulatory thresholds (Lambda-Cyhalothrin at 0.5 mg/kg, Cyhalothrin at 1 mg/kg, and Deltamethrin at 2 mg/kg).
Fully Self-Contained Kit Architecture: Arrives fully packed with 10 test cassettes, 10 microwells, 1 bottle of dedicated extracting solution (50 mL), 2 sampling bottles (30 mL), and a user manual.
Definite Visual Interpretation: Utilizes a competitive lateral flow immunochromatographic format where an increasing insecticide concentration causes the Test (T) line to fade or disappear, removing subjective reading errors.
Long-Term Ambient Preservation: Unopened test kits can be safely kept tightly sealed in a cool, dry location between 4–30°C for an extended shelf-life of up to 18 months.

Validated for multi-matrix pyrethroid screening across agricultural produce:
STEP 1 Extraction Cut fresh sample into 0.5 cm pieces. Weigh 1 g into sampling bottle, add 3 mL extracting solution, shake 1 min, let stand 1 min. (Centrifuge if cloudy). | STEP 2 Microwell Step Ensure 20–40°C environment. Pipette 100 µL supernatant into microwell, mix gently 3–5 times with pipette, and let stand undisturbed for 3 min. | STEP 3 Load Cassette Transfer 100 µL of mixed solution from microwell directly into round sample hole on cassette. Start timing immediately for lateral flow migration. | STEP 4 Read at 5–8 Mins Interpret visual lines strictly at 5–8 minutes. Visual readouts become strictly invalid after 8 minutes due to late chemical shifts. |
Negative (-): Both Control (C) line and Test (T) line develop strong, distinct red bands. Targeted pyrethroid residues are safely below regulatory threshold cutoffs.
Positive (+): Control (C) line develops normally, but Test (T) line is visibly lighter or fails to appear → Pyrethroid residues ≥ targeted threshold limit.
Invalid: Control (C) line fails to show any visible color band. Re-testing with a new cassette is required.
Adhere to strict operational parameters to ensure maximum screening accuracy:
Qualitative Screening Purpose: Engineered strictly for qualitative preliminary screening; not intended for precise quantitative concentration evaluation.
Time-Sensitive Exposure: Perform test within 1 hour after removing cassette from protective packaging to avoid moisture interference.
Strict Time Window: Read visual test results strictly between 5–8 minutes after loading cassette; results observed after 8 minutes are invalid.
Kit Components Included: 10 Test cassettes, 10 Microwells, Extracting solution (50 mL) x1, 30 mL Sampling bottles (x2), User Manual.
Required Equipment (Not Provided): Scissors, electronic balance (1 g precision), micropipette (100 µL), centrifuge (optional, for turbid extracts), and timer.
