Allergy Evaluation

Drug allergy is a reaction caused by drugs and is a special type of adverse drug reaction. Our company's allergy evaluation service is a simplified workflow by a group of specially trained and experienced scientists. We offer comprehensive services and technical support, designed to help our clients address possible barriers and challenges in rare disease therapy research and development.

Introduction to Allergy

Allergy refers to a specific immune response that manifests as tissue damage or physiological dysfunction after the body is re-stimulated by the same antigen. It is an abnormal or pathological immune response. Drug allergies generally occur after multiple exposures to the same drug. There is an incubation period for the first onset, but the recurrence can occur immediately. It occurs due to an abnormal immune response, which is generally harmful to the human body. Allergies are generally divided into four types.


  • Type I

    Common symptoms:

    rash, itching, sneezing, runny nose, asthma attack, etc.

  • Type II

    Common symptoms:

    anemia, bleeding purpura, etc.

  • Type III

    Common symptoms:

    fever swollen lymph nodes, joint swelling and pain, kidney damage, etc.

  • Type IV

    Common symptoms:

    eczema, herpes, skin pigmentation, etc.

Animal Models for Allergy

Animal models are very important for allergy evaluation. They are the premise of screening allergens in drugs and the basis of preventing the occurrence of allergic reactions to drugs. Mice and rats are widely used in allergy evaluation. Among them, mice are commonly used as experimental animals for drug sensitization models due to their diverse immunological and molecular reactions. SD rats have the advantages of high sensitivity and good reproducibility. In addition, beagles, miniature pigs, and guinea pigs are also additional choices for allergic reaction research models.
