House dust allergies are a reaction to the particular allergens found inside a house, such as dust mites, pollens, etc. The daily use items such as bedding, upholstered furniture, etc., form an ideal ground for the shelter and growth of allergens.

As an immune response to the allergens, the body produces antibodies which trigger chemical releases such as histamines, leukotrienes, and prostaglandins from immunoglobulin E (IgE) cells to combat the spread of the perceived infection and pathogens. The immune system develops house dust (Hollister-Stier) (h2) IgE antibodies upon interaction with the pathogen. Due to the reaction, the affected patient experiences inflammation along with other uncomfortable symptoms in the body.

The most common symptoms of the allergic reaction consist of:

  • Persistent sneezing
  • Runny nose
  • Itchy, watery, or red eyes
  • Nasal congestion 
  • Uncomfortable post-congestion nasal dripping
  • Facial pressure 
  • Swollen and bluish skin under the eyes
  • Scratchy roof of the mouth or nose

The severe allergic reaction can have asthma-inducing effects such as:

  • Chest pressure and tightness
  • Audible wheezing sound with exhalation 
  • Difficulty sleeping due to shortness of breath, wheezing or coughing
  • Chronic bouts of coughing similar to respiratory illnesses like flu or cold

In certain extreme cases, the allergy can cause an anaphylactic reaction, eczema flare, and severe asthma attack. Since most of the symptoms of the allergy are similar to the flu, it's difficult to diagnose the specific causes of the reaction without an allergy house dust (Hollister-Stier Labs) test. The analysis assists the medical practitioner in detecting the underlying causes of the present signs and preventing the severity of the allergy.

For IgE house dust, Hollister-Stier (H-S) laboratory test, a lab technician draws out blood from the arms of the affected individual. The blood specimens are collected in a vial to extract the serum for house dust (Hollister-Stier) (h2) IgE antibody detection. The sample is centrifuged first for extracting the clear liquid called serum, upon which the tests are performed with immuno-sensitive chemicals.

Usually, the blood sample collection for Hollister-Stier allergy testing causes little to no side effects. However, in a few patients, it can form complications like:

  • Bruising at the site of extraction
  • Bleeding at the needle insertion part
  • Mild rash
  • Skin irritation due to bandages
  • Clogged vein due to inflammation
  • Dizziness due to a vasovagal reaction 
  • Infection at the needle insertion site due to lack of post-collection hygiene.

The symptoms subside within 1-3 days. In the event of prolonged discomfort post collection, the patient must visit a medical expert at the earliest.
