The manifestation of an allergic reaction is always accompanied by a number of unpleasant symptoms, among which the most harmless are the runny nose, tearing of the eyes, redness of the eye proteins. Some manifestations of allergy of any kind can greatly worsen overall well-being, negatively influence social contacts and even lead to serious consequences in the absence of the necessary medicinal effect.
Carrying out skin allergoprobes allows to identify the causes of allergies in a timely manner, narrow the circle of "suspects" - provoking factors that can become the starting point for manifesting this unpleasant condition. This simple analysis is especially important for allergic manifestations in childhood, when the child is not yet able to fully describe his feelings and requires treatment for symptomatic relief in the shortest possible time. This article will tell you in detail about where you can take and how skin allergens are done to children and adults, at what age, and what allergens are.
What are skin allergens
Skin allergens are a set of manipulations that can detect a particular sensitivity of the body to certain substances of chemical or natural origin. At the same time you can see which situations or even at what time of year the allergic symptoms can manifest themselves most. Through this analysis it becomes possible to avoid the negative effects of allergens( substances that, if ingested, have a negative effect).
Modern methods of dermal allergic tests allow avoiding unpleasant sensations, are carried out in a short time and provide the most accurate information about substances with negative effects on the body. At the same time, the cost of this manipulation is quite affordable, which allows you to get the most complete picture of your health to almost everyone.
The doctor of one of the well-known clinics in this video will tell you about what allergens are:
To whom they are appointed
Allergy test is prescribed by an allergist doctor in the course of revealing the causes of allergy. Usually, in parallel with this study, a series of blood tests, urine tests are carried out, which are also aimed at determining allergens. Thanks to allergic tests, it becomes possible to make the most effective treatment, which will help to remove allergic manifestations and stabilize the state of health.
Allergens for skin can be used for adults and children. This diagnostic procedure does not have contraindications.
What is the procedure for
The procedure of skin allergic tests is carried out to determine all types of allergens that cause allergy manifestations in humans. It can be prescribed in the following cases:
- with frequent allergy and its seasonal exacerbations;
- when allergic manifestations occur for no apparent reason;
- with frequent colds and lachrymation without apparent cause;
- with suffocation, difficulty breathing, coughing and bronchospasm;
- in case of edema of the skin;
- often itchy eyes, there are abundant discharge from the nose without manifestations of a cold;
- is probably the occurrence of an allergy after allergic manifestations on animal hair or animal bites.
Often appearing disorders of the digestive system in the form of diarrhea and constipation, the appearance of rash on the skin, the urge to vomit - are also the reasons to make skin allergic tests. This is called for by dietitians, who often encounter such manifestations of food allergies.
Its types
Today, medical institutions offer several varieties of this procedure that allow you to determine the sensitivity of the organism to many types of the most common allergens.
There are the following types of skin allergic tests, prescribed with the body's predilection for pathological manifestations for no apparent reason:
- qualitative;
- is quantitative;
- provocative.
Each of the listed species has a number of subspecies, which differ in the method used for carrying out this procedure and in the method for analyzing allergens.
So, the qualitative kind of cutaneous allergic test is divided into:
- subcutaneous,
- drip,
- performed by scratching,
- injections,
- as well as application and indirect.
Quantitative allergoproby allows you to determine not only the presence of an allergy to a certain substance, but also the possibility( the tendency of the body) to manifest allergic reactions.
Provocative allergic tests are subdivided into the following subspecies:
- leukocytopenic;
- thrombocytopenic;
- thermal;
- cold;
- inhalation;
- nasal;
- exposure.
The above variants differ in the method of carrying out, but they all allow to determine the type of allergen to which the organism is most sensitive, and also to prevent possible serious negative manifestations when taking medications( for example, before surgery to exclude allergic shock to the drug) and in the testing of cosmetologymeans.
Indications for
The implementation of cutaneous allergic tests is usually indicated for those who have either a tendency to manifest allergic reactions, or already have an allergy. In the presence of any type of allergy to virtually any substance of natural or chemical origin in humans, there is a significant propensity to develop other types of allergic reactions. So, especially allergic tests are prescribed with:
- urticaria:
- cholinergic,
- Quinck edema,
- aquatic,
- cold,
- thermal, etc.,
- skin erosions,
- allergic contact dermatitis,
- echinococcosis.
The tendency to develop an allergic reaction can be observed in children whose parents also had any allergies. Therefore, in this case, a doctor may be appointed to conduct allergic tests as prevention and exclusion of contact with a certain allergen.
About when it is better to undergo allergic tests, the expert in this video will tell:
Contraindications to the use of
There are a number of situations when this diagnostic procedure can be contraindicated. These include the following:
- period of exacerbation of allergies, as well as remission after exacerbation of less than 10 days - at this time the body is actively recovering, and the additional effect on it in the form of a dose of an allergen is contraindicated;
- old age - more than 60 years;
- period of pregnancy, as well as breastfeeding;
- when taking glucosterol preparations. After a period of application, at least two weeks must pass;
- at the time of taking any kind of antihistamine drug, since in this case the efficiency of the spent allergic test is significantly reduced;
- for exacerbation of any chronic disease.
Safe procedure
The safety of this procedure for the detection of an allergen is proved by numerous practical experiments. However, the presence of contraindications must be taken into account before carrying out this manipulation of a diagnostic nature.
For example, in early childhood, carrying out allergic skin tests can bring certain harm to an unborn child, since up to three years is considered to be not yet fully formed human immunity. Also, this procedure is unsafe if the organism is sensitive to a certain kind of allergen: in this case, the extremely undesirable consequences of introducing an allergenic substance are likely.
In any case, the dermal allergenprobe is carried out only under the supervision of a doctor and in the conditions of a medical institution. Next we will tell you how to prepare for allergens.
Preparing for the
survey So, are there any special features in preparation for allergic tests to children and adults?
- Before carrying out this procedure, the main requirement is the absence of significant loads, both physical and psychological, in order to avoid possible negative consequences.
- Immediately before the procedure itself, the skin at the injection site is treated with any kind of antiseptic.
On how allergens are made to children and adults, we will tell further.
How everything passes
The injection is usually carried out at the point of flexion of the bows in the forearm area, however, if necessary, the dose of the allergen can be administered in the back area. On the surface treated with antiseptic, allergen samples are applied, then - a skin prick, the needle penetration is made to a depth of at least 1 mm.
Sensations with particularly pronounced negative manifestations are not noted, since the depth of the skin prick is minimal. The result is evaluated after 20 minutes after the application of allergens.
Decoding of results
The process of decoding the obtained results of allergic tests is carried out only by a specialist who has experience and data for this.
The formation of redness at the injection site indicates the extent to which there is an allergy to a certain type of allergen:
- The appearance of severe redness in the next few seconds after the procedure indicates a positive reaction to this allergic test.
- The appearance of redness of the skin in the area of the injection within the prescribed 20 minutes indicates an immediate reaction to the allergen.
- If the reddening of the skin is noted only within the next 24-48 hours, then we can talk about a delayed reaction to the allergen.
The doctor also evaluates the reaction on a specific scale from 0 to 4 points.
Next we will tell you about the prices for skin allergens for adults and children.
Average cost of an allergy test
So, how much are allergens? Today, skin allergic tests are an affordable exercise that preserves the health of adults and children: the average cost is from 850 to 1,580 rubles, depending on the type of sample and the pricing policy of the medical institution. About where to make allergens, your doctor will tell you.
