Cockroach allergy is a respiratory condition triggered by immune system sensitivity to proteins found in cockroach waste, saliva, and body parts. It is caused by inhaling microscopic cockroach allergens that become airborne and provoke IgE antibody production in sensitive individuals. The Respiratory Allergy Panel for your region is the most important test for diagnosis because it measures specific IgE antibodies to cockroach allergens.

Cockroach allergy is caused by proteins found in cockroach feces, saliva, shed skin, and decomposing body parts. When cockroaches infest homes, these microscopic particles become airborne as dust and are inhaled by occupants. Your immune system mistakenly identifies these harmless proteins as dangerous invaders and produces immunoglobulin E (IgE) antibodies in response, triggering allergic symptoms. The problem is particularly severe in warm, humid climates where cockroach populations thrive year-round.
The Respiratory Allergy Panel for your region is the most important test for cockroach allergy because it measures specific IgE antibodies to cockroach allergens in your blood. These region-specific panels test for cockroach sensitivity alongside other common environmental allergens in your area, including the Respiratory Allergy Panel Region III for Georgia and northern Florida, the Respiratory Allergy Panel Region IV for southern Florida, and similar panels for Alabama, Arkansas, Louisiana, Mississippi, Kansas, Nebraska, and California. The blood test detects elevated IgE antibodies that indicate your immune system is actively reacting to cockroach proteins, helping confirm whether cockroaches are causing your respiratory symptoms like asthma, wheezing, or chronic congestion.
You should get tested if you experience persistent respiratory symptoms like wheezing, coughing, or shortness of breath that worsen at home, especially at night or in humid weather. Consider testing if you have year-round nasal congestion, frequent asthma attacks with no clear trigger, itchy or watery eyes, skin rashes, or ear infections that do not respond well to treatment. Testing is particularly important if you live in warm, humid climates or in older buildings where cockroach infestations are more common, or if your symptoms improve when you spend time away from home.

What this means
Your IgE antibodies to cat dander are moderately elevated, indicating a significant allergic sensitivity to cats. This level of sensitization commonly causes symptoms like sneezing, itchy eyes, nasal congestion, or even breathing difficulty when exposed to cats or environments where cats have been. Even if you don't own a cat, exposure can occur in homes, offices, or on clothing of cat owners.
Recommended actions
Avoid direct contact with cats and limit time in environments where cats live
Use HEPA air purifiers in your home to reduce airborne cat allergen particles
Wash hands and change clothes after visiting homes with cats
Consider discussing allergy medications or immunotherapy with your doctor if avoidance isn't practical
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
