About this test
The rat serum protein allergy test is a blood test that measures immunoglobulin E (IgE) antibodies against proteins found in rat serum, the liquid portion of rat blood. It helps determine whether exposure to rat serum proteins is contributing to allergy symptoms such as sneezing, nasal congestion, itchy or watery eyes, coughing, or wheezing. Rat serum proteins can be present in laboratory settings and in dust where rodents are handled. The test is typically ordered for laboratory and animal-care workers, as well as others with recurring symptoms around rats.
What this test measures
- Rat serum protein-specific IgE Detects IgE antibodies that bind to proteins in rat serum.
Who this test may be right for
- Laboratory and animal-care staff who handle rats or rat tissues.
- Researchers and technicians with occupational exposure to rat serum or blood products.
- People with asthma or rhinitis that worsens in rat housing areas.
- Those being assessed for suspected rat-related allergy.
Before your visit
- No fasting is required.
- Inform the clinician about antihistamines or other allergy medications.
- Continue prescribed medications unless a healthcare provider says otherwise.
- Wear a top that allows easy access to the arm.
Understanding your results
A positive result suggests the body has produced IgE antibodies to rat serum proteins, which may indicate a sensitivity contributing to nasal, eye, or airway symptoms after exposure. A negative result makes rat serum allergy less likely but does not exclude epithelium, urine, or other rat proteins. Occupational exposure can be ongoing, so symptoms may persist until exposure is reduced. Discuss results with a healthcare provider for a complete interpretation.

Questions people ask
What does the rat serum protein allergy test measure?
It measures rat serum protein-specific IgE antibodies in the blood, which can indicate sensitization to proteins in rat serum.
Why test for serum separately from epithelium or urine?
Rat serum contains distinct proteins, so serum-specific IgE targeting can help identify a particular exposure source that other rat tests might miss.
Do I need to fast before the test?
No. Fasting is not required for this blood allergy test.
How long until results are ready?
Turnaround is typically 1-3 business days.
