Skin prick testing. This involves placing drops of possible allergens onto an individual’s skin, usually the lower forearm.  The arm is then pricked to allow the allergen to be introduced.  Within 15 minutes, it is usually possible to see if an individual is developing an allergic reaction, as a small itchy patch will appear.  It is important that you are well informed about what is involved with this type of testing by a healthcare professional, as certain medications can affect the results.

Blood testing, known as RAST (radioallergosorbent test).  The test measures the levels of allergic antibodies in the blood to allergens.  If the levels of these antibodies (known as IgE) are high in the blood, it suggests that the individual is allergic.

Patch testing.  This type of Allergy Testing is used to test individuals with dermatitis.  Small patches with the allergen on them are placed on the skin (usually the back).  These patches are left in place for 48 hours. Once removed, the practitioner will look for symptoms of an allergic reaction.  The patient will also be assessed again a few days later, to determine the extent to which a person is allergic.

Elimination testing.  This involves removing suspect foods from the diet for several weeks, and then slowly reintroducing them.  During this time, the individual keeps a diary, writing down anything the may indicate a reaction.   After a period of time, foods are reintroduced, one at a time, until again symptoms are observed.  This is quite an arduous procedure, and should be done with the guidance of a professional healthcare practitioner.

These are also numerous holistic approaches to testing an individual for allergies.  Here are just a couple that are sometimes used.

Kinesiology.  This involves asking the body through muscle testing if there are any imbalances in the body.  The practitioner can test for specific allergens.

Vega testing.  This involves measuring the body’s electro magnetic response to specific substances tested.
