Sulfonamides Rapid Test Kit for Egg and Egg Product Screening

Not just a rapid test supplier — a long-term, globally proven food safety partner.

Fast screening for sulfonamide residues in eggs, egg products and related poultry-derived food matrices.

The Sulfonamides Rapid Test Kit provides a fast, simple and reliable front-end screening solution for egg producers, layer farms, egg processors, exporters, laboratories, inspection authorities and quality control teams seeking to identify veterinary drug residue risks before laboratory confirmation, shipment or market release.

Suitable for egg quality control, supplier verification, export risk control, market surveillance and food safety monitoring applications.

Product Principle & Result Interpretation

This rapid test kit is based on competitive lateral flow immunochromatographic assay technology and is designed for rapid qualitative screening of sulfonamide residues in egg matrices.

Results can be interpreted visually for routine front-end screening. Optional quantitative analysis is available for users requiring objective result interpretation, numerical result management, digital records and traceable QC workflow management.

The test is suitable for high-frequency screening in layer farms, egg collection centers, egg processing facilities, export preparation, market inspection and laboratory pre-screening applications.

Fast • Simple • Reliable

Rapid Results in 3–5 Minutes

Support immediate batch release, hold, re-check or laboratory confirmation decisions.

Visual Screening, No Instrument Required

Simple operation suitable for egg producers, processing facilities, inspection teams and routine high-volume screening programs.

Optional Quantitative Analysis

Supports objective result interpretation, numerical result management, digital records and traceable QC workflow management.

Egg Industry Ready

Suitable for shell eggs, fresh eggs, liquid egg products, egg powder and processed egg products.

Laboratory-Verified Performance

Supported by CMA / CATL / CNAS certified analytical laboratories with LC-MS/MS, GC-MS/MS and real-matrix validation capability.

Target Compounds Covered

This rapid test kit is designed for screening major sulfonamide residues, including:

• Sulfamethazine (SMZ)

• Sulfadiazine (SDZ)

• Sulfamethoxazole (SMX)

• Sulfamonomethoxine (SMM)

• Sulfaquinoxaline (SQ)

These compounds are commonly monitored in poultry and egg residue-control programs worldwide.

Why Screen for Sulfonamide Residues in Eggs?

Sulfonamides are among the most frequently monitored veterinary drug residues in egg safety programs and international egg trade.

Many egg importers, food brands and regulatory authorities include sulfonamide residues in routine testing programs as part of export compliance and supplier qualification requirements.

Egg producers, processors, exporters, laboratories and inspection authorities routinely screen for sulfonamide residues to support:

• Veterinary drug residue monitoring

• Egg export compliance

• Supplier and farm verification

• Incoming material inspection

• Egg processing quality control

• Buyer testing program compliance

• Market surveillance programs

• Regulatory compliance monitoring

• Shipment risk control

• Brand reputation protection

The detection of sulfonamide residues above permitted limits after shipment, buyer inspection or market release may result in shipment rejection, buyer claims, delayed payments, regulatory action and damage to supplier credibility.

Front-end rapid screening helps identify high-risk batches earlier and supports faster risk-control decisions before eggs enter processing, packaging or trade channels.
