Dust Mite Allergy Control
Not an allergy to dust per se,
allergic reactions to dust mites is a reaction to the proteins found in the feces
and bodies of dust mites - microscopic creatures that
love warm, humid areas like bedding and pillows. For dust mite
allergy control wash all blankets, bedspreads and pillows on a
regular basis and keep mattress enclosed in a mattress
cover.
However, if you don’t have an allergy,
dust mites won’t be harmful at all. For many airborne allergens
like house dust mite, the higher the level of exposure, the
higher the likelihood of a person producing "allergic"
antibodies. High allergen levels also increase a person's risk
of becoming allergic and developing asthma. It’s thought that
many asthmatics also have an allergy to dust mites.

How Is Allergy Testing
Done?
Allergy skin testing is a
safe and simple procedure that
can yield useful information
about your allergic
sensitivities. For more than a
century, doctors have used skin
tests to diagnose
allergies.
During these tests, your
skin is exposed to
allergy-causing substances
(allergens) and then is
observed for signs of an
allergic reaction. Along with
your medical history, skin
tests can confirm whether signs
and symptoms such as sneezing,
wheezing and skin rashes are
caused by allergies. They can
also identify the specific
substances that trigger
allergic reactions.
Skin allergy testing is
widely used to diagnose
allergic conditions such as hay
fever, allergic asthma and
dermatitis (eczema).
It's safe for people of all
ages, including infants and
older adults. If you want to
start immunotherapy — a series
of injections intended to
increase your tolerance to
allergens — you need either a
skin or blood test to identify
the substances that trigger
your allergies. Blood tests are
particularly useful for those
who should not undergo skin
tests. Although blood tests can
be as accurate as skin tests,
they're not performed as often
because they may be less
sensitive and are more
expensive.
Skin allergy testing is
usually performed in a doctor's
office. Typically, a nurse
administers the test and a
doctor interprets the results.
The three main types of skin
tests are: Puncture, prick or
scratch test. In this test,
which is the type of skin test
most commonly performed, tiny
drops of purified allergen
extracts are pricked or
scratched into your skin's
surface.
This test is usually
performed to identify allergies
to pollen, mold, pet dander,
dust mites, foods, insect venom
and penicillin. The second type
of test is the Intradermal test
where purified allergen
extracts are injected into the
skin of your arm.
This test is usually
performed if your doctor
suspects that you're allergic
to insect venom or penicillin.
The last type of test is the
Patch test where an allergen is
applied to a patch, which is
then placed on your skin. This
test is usually performed to
identify substances that cause
contact dermatitis. These
include latex, medications,
fragrances, preservatives, hair
dyes, metals and resins.
Contrary to popular
belief, skin tests cause little
if any discomfort. Because the
needles used in these tests
barely penetrate your skin's
surface, you won't bleed or
feel more than mild, momentary
pain. Some tests detect
immediate allergic reactions,
which develop within minutes of
exposure to an allergen. Other
tests detect delayed allergic
reactions, which develop over a
period of several days.

Dust mite allergy is an allergy to a microscopic organism
that lives in the dust found in all dwellings and workplaces.
House dust, as well as some house furnishings, contains
microscopic mites. Dust mites are perhaps the most common cause
of perennial allergic rhinitis. House dust mite allergy usually
produces symptoms similar to pollen allergy and also can
produce symptoms of asthma.
House dust mites, which live in bedding, upholstered
furniture, and carpets, thrive in summer and die in winter. In
a warm, humid house, however, they continue to thrive even in
the coldest months. The particles seen floating in a shaft of
sunlight
Include dead dust mites and their waste products. These waste
products, which are proteins, actually provoke the allergic
reaction.
When an allergen enters the body of a person with a
sensitized immune system, it triggers antibody production.
Histamine and other chemicals are released by body tissues as
part of the immune response. This causes itching and swelling
in affected tissues, mucus production, and in serious cases,
hives and rashes, as well as other symptoms.
Symptoms of dust allergy vary in severity from person to
person. Most environmental allergens contact the skin or eyes,
or are inhaled. Therefore, most symptoms affect the skin, eyes,
or the breathing passages. Allergies are relatively common.
Heredity, environmental conditions, number and type of
exposures can affect a predisposition to allergies. For reasons
that are not fully clear to scientists, allergies are on the
rise, particularly in so-called "Westernized" regions such as
the United States and Europe.
For dust mite allergy control wash all blankets,
bedspreads and pillows on a regular basis and keep
mattress enclosed in a mattress cover.
