Are my allergy levels of 0.75 kU/L normal?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I got the results from an allergy blood test. My specific allergy numbers ranged from 0 to 0.75 kU/L. My total IgE is 241 IU/mL.

  1. Does this total number indicate anything?
  2. Is the number high or low?

Please advise.

Thank you.

Hello,

Welcome to icliniq.com.

I read your query and understand your concern.

The IgE (immunoglobulin E, an antibody found only in mammals) value is within normal limits. Moreover, the total serum IgE values (a test that measures the quantity of immunoglobulin E in the blood) are not very indicative, rather, specific IgE levels (a test that measures how much IgE your body makes in response to a single allergen) are important. Specific IgE levels should be inferred in relation to the particular allergen. Each allergen level may be different. Currently, the most accepted form of testing for allergies is skin prick testing which is the gold standard. We do specific IgE blood tests only on those patients whose skin prick test is contraindicated, like pregnant ladies.

Your specific IgE levels need to be assessed in relation to the allergen.

  1. Can you share the whole report?
  2. Can you describe your symptoms to us?
  3. Have you had this problem for long?
  4. What medicines are you currently on?
  5. Are your problems seasonal or perennial?
  6. Is there breathing trouble or skin problems also?

I hope this helps.

Thank you.

Patient's Query

Hi doctor,

Thank you for your reply.

I have attached my report. My symptoms include an earache that feels deep on the left side; (it does not feel like a regular swimmer's earache). The eustachian tube on the left side is almost always closed (alleviated by holding the breath and blowing). Extreme back of mouth sometimes feels sore on the left side. An allergic shiners under both eyes (light purple color, very puffy). I have fluid behind the eardrum on both sides, worse on the left side. An occasional tickle in the throat causes a cough that is usually dry, but not always.

When waking up in the morning, my nose and throat feel more congested, and often have yellow or green phlegm (usually not much, though). My eyes feel heavy like I want to sleep even though I am not sleepy. Most of these symptoms have been ongoing for about seven years. I do not believe this is seasonal, because it occurs every day throughout the year. I do not believe there are skin problems.

Please help.

Thank you.

Hi,

Welcome back to icliniq.com.

Your symptoms correlate with allergic rhinitis and it is sequelae. Most probably you have a sensitivity to perennial allergens like molds, house dust mites, and animal dander. Dermatophagoides are house dust mite species, and they are commonly found in carpets, curtains, upholsteries, soft toys, pillows, and bedding inside the house. You need special measures to get rid of them.

1. You can get these items stitched or remade with an allergen-free material.

2. Washing these in water of 122 degrees Fahrenheit after keeping them immersed in that temperature for an hour can remove the mites and their droppings.

3. Molds need moisture for growth. Make sure that the interior humidity of your house is not more than 40 percent.

4. Check the air-conditioner filters and recirculated air.

5. Animal dander can be avoided by best removing the pet from the house.

I hope that you get your answer.

Please let me know if you want some help.

Thank you.
