Allergen, Individual-Animal Rat Epithelium E73

The Allergen, Individual-Animal Rat Epithelium E73 test is a targeted allergy assay that measures specific IgE antibodies directed against rat epithelium proteins (E73). Performed from a blood sample collected at home by a certified phlebotomist, it identifies sensitisation to rat-derived allergens to confirm whether symptoms such as rhinitis, conjunctivitis, or asthma are triggered by exposure to rats.

This test is important for residents across Dubai and the UAE who suspect rodent-related allergic responses—particularly those working in laboratories, pet shops, pest-control environments, or living in residences with rodent exposure. Results help clinicians and allergy specialists develop personalised avoidance strategies, guide treatment choices (including pharmacotherapy or immunotherapy), and support occupational health risk assessments in the UAE healthcare context.

• Rat epithelium (E73) specific IgE
• Quantitative IgE level (kUA/L)
• IgE class / sensitisation category (e.g., Class 0–6)

• Recurrent allergic rhinitis or persistent sneezing around suspected rat exposure
• New or worsening asthma symptoms without clear cause
• Workplace exposure (laboratory staff, pest control, pet shops)
• Unexplained chronic conjunctivitis or eye itching
• Before starting allergen immunotherapy when rat allergy is suspected

• Accurate identification of sensitisation to rat epithelium (E73)
• Enables personalised avoidance and home remediation plans
• Supports clinical decisions on treatment and immunotherapy
• Home sample collection across Dubai and the UAE for patient convenience

• At-home blood collection (capillary finger-prick or venous) by a certified phlebotomist
• No fasting required prior to sample collection
• Notify the collector/clinician of current allergen immunotherapy, biologics, or recent systemic steroids
• Must be available at the scheduled appointment and be a resident in Dubai or elsewhere in the UAE
