The scope of our drug testing includes but is not limited to: quinolones (floxacin, anthranofloxacin, danofloxacin, sarafloxacin, ofloxacin, ciprofloxacin, oxquinic acid, etc.), sulfonamides Drugs (sulfadiazine, sulfathiazole, sulfachloropyridazine, sulfaquinoxaline, etc.), tetracycline drugs (oxytetracycline, chlortetracycline, etc.), non-steroidal anti-inflammatory drugs, aminoglycosides (kanamycin, bromycin, streptomycin, gentamicin, neomycin, etc.), macrolides (erythromycin, spiramycin, tylosin, tilmicosin, etc.), bacitracin zinc, β-lactamase, nitrobenzonitrile, cyromazine, melamine, azapiperone, cephem, nitrofurazone, ketoconazole, etc.

Technical Advantages

• Fast detection, no time-consuming
• Strong identification of drugs and high sensitivity
• Easy to operate, technicians can complete the test independently according to the instructions
• The equipment is simple, and the detection can be completed alone without auxiliary instruments
• Low requirements for testing environment, testing and storage at room temperature

How we do?

• Alfa Chemistry experts develop gold-labeled antigen-antibody and main materials required for reagent strip composition for the drug to be tested.
• Alfa Chemistry provides technical support such as sample processing, detection methods and reference ranges.
• Alfa Chemistry can analyze detection results in combination with minimum detection limits, specificity studies and methodological comparisons.
