Parathion Rapid Test Kit
Brand: FSTest
5–8 mins Rapid Readout Time | 50 µg/kg Strict Parathion LOD | 10 Tests Complete Kit Pack | 12 Months Shelf Life (4–30°C) |
The FSTest Parathion Rapid Test Kit is a professional-grade, lateral flow immunochromatographic assay designed for the swift, qualitative screening of parathion residues in fresh fruits and vegetables.
Parathion is a highly regulated, high-toxicity organophosphorus insecticide. By bypassing the need for expensive, time-consuming laboratory chromatography infrastructure (such as HPLC or GC-MS), this field-ready kit compresses complex agricultural sample extraction into a simplified room-temperature workflow, serving as an indispensable first-line defense in fresh produce supply chains and corporate food safety compliance monitoring programs in just 5 to 8 minutes.
High-Speed Field Turnaround: Complete the entire assay workflow and achieve highly reliable visual result readouts within just 5 to 8 minutes post-preparation.
Highly Sensitive Baseline Detection: Calibrated to deliver dependable qualitative screenings at a strict Limit of Detection (LOD) of 50 µg/kg (0.05 mg/kg or ppm) across fresh produce matrices.
Fully Self-Contained Kit Architecture: Arrives fully packed with 10 test cassettes, 10 pre-loaded microwells, a generous 100 mL bottle of extracting solution, and 2 sampling bottles (30 mL).
User-Friendly & Field-Ready: Completely eliminates the need for complex boiling or laboratory fluidics calibration; simple hand-shaking or vortexing enables execution anywhere in the supply chain.
Definite Visual Interpretation: Utilizes an inverse competitive immunochromatographic format where an increasing insecticide concentration causes the Test (T) line to fade or disappear, removing subjective reading errors.

| Parathion (Organophosphorus Insecticide) | 56-38-2 | 50 µg/kg (0.05 mg/kg or ppm) |
Validated for multi-matrix organophosphorus screening across fresh agricultural produce:
STEP 1 Extraction Cut fresh sample into 0.5 cm pieces. Weigh 2 g into sampling bottle, add 5 mL Extracting Solution, vortex/shake 1 min, let stand 1 min. | STEP 2 Microwell Step Ensure 20–40°C environment. Pipette 100 µL clear supernatant into microwell, mix gently 3–5 times, and let stand undisturbed for 3 min. | STEP 3 Load Cassette Transfer exactly 100 µL of mixed solution from microwell directly into round sample hole on cassette. Start timing immediately. | 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. Parathion residue is safely below 50 µg/kg.
Positive (+): Control (C) line develops normally, but Test (T) line is visibly lighter or fails to appear → Parathion residue ≥ 50 µg/kg 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 foil pouch to avoid ambient moisture damage.
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 (100 mL) x1, 30 mL Sampling bottles (x2), User Manual.
Required Equipment (Not Provided): Scissors, electronic balance (2 g precision), micropipette (100 µL), centrifuge (optional, for turbid extracts), and timer.
