The FSTest Avermectins Rapid Test Kit is an advanced, competitive lateral flow immunochromatographic assay engineered for rapid qualitative screening of avermectin (abamectin) pesticide residues across fresh fruits and vegetables.

Avermectins are widely applied macrolide antiparasitic and insecticidal agents strictly controlled under international Maximum Residue Limits (MRLs). With an exceptional baseline sensitivity of 0.01 mg/kg (10 ppb) and multi-matrix dilution tables calibrated to specific statutory thresholds, this test kit provides agricultural farms, wholesale produce markets, supermarket quality assurance teams, customs border quarantine checkpoints, and testing laboratories with a dependable, mobile on-site screening method that delivers visual results in just 5 to 8 minutes without requiring heavy analytical instruments.

2. Key Benefits

Ultra-High Analytical Sensitivity (0.01 mg/kg Baseline LOD): Features an ultra-sensitive baseline detection threshold of 0.01 mg/kg (10 ppb), ensuring trace-level compliance with strict global agricultural safety regulations.
Fast 5–8 Minute Readout: Generates clear, visual qualitative results within 5 to 8 minutes post-application, greatly expediting harvest release, intake screening, and port quarantine.
Broad Multi-Matrix Validation: Includes pre-calibrated dilution ratios covering more than 40+ agricultural commodities (root tubers, leafy greens, cucurbits, brassicas, solanaceous fruits, legumes, stone/pome fruits, berries, and tea leaves).
Safe & Non-Toxic Extraction Solution: Formulated with an eco-friendly, non-toxic extraction solution that guarantees user safety and simplifies routine laboratory waste disposal.
Zero Cross-Reactivity with Common Agrochemicals: Exhibits superior analytical specificity; samples containing 10 mg/L of Imidacloprid, Triazophos, Parathion, Carbofuran, and Omethoate all test negative.

4. Applicable Sample Types

Optimized specifically for identifying avermectin residue levels across fresh produce commodities:

Root & Tuber Vegetables (Potatoes, radishes, sweet potatoes, ginger, wild rice stem) Brassica & Leafy Greens (Cabbage, cauliflower, broccoli, celery, spinach, bok choy, lettuce, mustard greens) Solanaceous, Cucurbits & Legumes (Tomatoes, sweet peppers, cucumbers, zucchini, bitter gourd, cowpea, soybeans) Orchard Fruits, Berries & Tea (Apple, pear, peach, grape, strawberry, citrus, kiwi, banana, mango, lychee, tea leaves) Farms, Produce Logistics Hubs, Supermarkets & Quarantine Checkpoints

5. Test Procedure

STEP 1

Extraction

Chop sample into 0.5 cm pieces. Weigh 1.0 g (±0.05 g) into a 30 mL sampling bottle, add 3 mL Extracting Solution, invert gently 50 times (do not shake vigorously).

STEP 2

Matrix Dilution

In a 2 mL tube, mix X µL clear supernatant with Y µL extracting solution according to the matrix guide table, and vortex for 10 seconds to mix thoroughly.

STEP 3

Microwell Incubation

Ensure 20–40°C environment. Pipette 120 µL prepared solution into a microwell, mix up and down 3–5 times with pipette, and incubate undisturbed for 3 minutes.

STEP 4

Load & Read (5–8 Mins)

Transfer all mixed liquid from microwell into cassette sample well. Interpret visual lines strictly at 5–8 minutes. Results are completely invalid after 8 minutes.

Visual Results Determination Guide:

Negative (-): Both Test (T) line and Control (C) line appear clearly. T line color intensity is equal to or darker than C line → Avermectins are absent or below the specific LOD threshold. Sample passes screening.
Positive (+): Control (C) line appears distinctly, while Test (T) line is invisible or visibly weaker/lighter than C line → Avermectins residue is present at or above the designated LOD. Confirmatory testing recommended.
Invalid: Control (C) line fails to appear, regardless of whether T line is present or absent. Re-test with a new unit.

6. Performance & Crucial Operational Controls

Adhere to strict operational parameters to ensure maximum screening accuracy:

Qualitative Screening Purpose: Intended for preliminary qualitative screening; suspicious or borderline samples should be confirmed using standard reference laboratory methods (e.g., LC-MS/MS).
Gentle Inversion Mixing: Invert the sampling bottle gently 50 times during extraction; avoid vigorous shaking to prevent sample emulsion or excessive foaming.
Moisture Protection: Begin testing within 1 hour after removing the test cassette from the sealed foil packaging to avoid moisture-induced strip deterioration.
Strict Time Window: Read visual test results strictly between 5–8 minutes after sample mounting; results interpreted after 8 minutes are invalid.

7. Included Components & Auxiliary Equipment

Kit Components Included: 10 Test Cassettes (individually sealed with desiccant in foil pouches), 10 Microwells (pre-coated reagent wells), 1 bottle of Extracting Solution (50 mL), 20 Centrifuge Tubes (2 mL), 2 Sampling Bottles (30 mL), User Instruction Manual.
Required Equipment (Not Provided): Knives/scissors, precision balance (±0.05 g precision), timers, micropipettes (100 µL, 200 µL, 1000 µL range) & pipette tips, vortex mixer, and centrifuge (optional, for turbid supernatants).
