Differential diagnosis allergy

 Allergies because you contact caused by a particular substance, but cold is caused by a contagious virus.

    And allergies and colds will be accompanied by a runny nose, sneezing, itchy throat. But allergies can cause itchy eyes tearing, and dry cough cough is caused by allergies. In turn, coughing and sneezing with phlegm like a cold.

    Other Criteria include:

    When allergy nose was clear, while a cold start nose was clear, but after a few days snot yellow or greenish.

    Allergies no fever, flu-like fever.

    Colds often last 5-10 days, allergy time may be very long.

    Time can be used to determine the incidence of allergies or colds, when each spring flowering tree has a "cold" is likely to be allergic to pollen.

    If your blocked nose, allergies and colds are likely to develop sinusitis . The main symptoms are runny nose, sinusitis, and allergies and colds is different, it will be accompanied by fever, sinus, skin irritation, pain and other symptoms.

Allergy which checks should be done?

Presence of antibodies to diagnose allergic diseases.

    Normal [skin reactions] negative (-), [blood like] eosinophils 5% or less, [IgE] negative (0.005mg / dl or less) ECISA France 0.1-0.9mg / l

    Showing abnormal values ​​of the major diseases of allergic rhinitis , bronchial asthma , drug allergies, atopic dermatitis allergic skin disease

    What checks

    ○ What is anaphylaxis

    When there are foreign substances into the human body, the human body will form a material to resist foreign bodies to protect the body tissues. Foreign substances called antigens such outside, while the material resistance is called antibodies.

    Once the human body to form antibodies after just one antigen invasion, will have antibodies to resist and cause allergic reactions.

   ○ The inspection can understand matters

    This occasionally cause abnormal body structure, i.e., the amount of antibody required amount exceeds the above scenario. As a result, there will be a rash, fever, throughout the body in shock and other symptoms. Allergies to check is to investigate whether there is abnormal allergic reactions, antigen types of inspection or investigation.

   ○ inspection methods

   Skin reaction test was to investigate the antigen; allergy blood test is judged abnormal.

   [Skin reaction test] on the patient's skin to give reactions observed suspicious original disease. Method to check the reaction of diluted antigen subcutaneous injection in the skin, and apply a small amount of antigen in the skin, wipe the surface of the tape is attached to paste test.

    [Blood like checking] when there is an allergic disease, eosinophilic leukocytes types of white blood cells (division) will increase. Survey eosinophilic leukocytes in the ratio to be judged.

    [ICE] to check whether the use of radioisotopes investigate serum IgE (immunoglobulin E).
