Ten Signs That You Need an Allergy Testing

Due to sunscreen products containing multiple active ingredients it is often difficult to determine the cause of dermatitis. Patch testing for the individual component is the only exact method for determining which of the chemicals the allergen is.

Patch testing and photopatch testing of topical sunscreen preparations may be performed if the active sunscreen ingredient is the suspected allergen. The prevalence of allergy to chemical absorbers in sunscreens is not known for the general population, however, in patch test clinics the prevalence of allergy to the active sunscreen component appears to be quite low. On the other hand, photopatch testing shows sunscreen chemical absorbers to be a common cause of photoallergic contact dermatitis. Hence it is important to carry out photopatch testing in addition to patch testing.

Ige Specific Blood And Skin Test Work Identically

Contributed by Anke Tillman

A RAST is a way of measuring the amount of IgE antibody in the blood stream made against a specific allergen. RAST tests and allergy skin tests give similar information. Both identify IgE antibody against materials you might be allergic to. RAST tests must be done by specific methods to be accurate and therefore must be sent to specific laboratories. RAST tests and skin tests each have their advantages and disadvantages. Skin tests may pick up some allergies that would be missed by RAST tests but skin tests have a small risk of precipitating an allergic reaction.

RAST tests report IgE made against specific foods in units known as KU/L. Higher levels indicate a higher chance you will have a reaction if you eat the food. Lower levels indicate a lower chance you will have a reaction.

Traditionally RAST TESTS have been reported as CLASS 0 to CLASS 5 or 6. Class 0 indicates no allergy. Class 5 or 6 indicates high allergy


The significance of a result varies with the degree of reaction on the test and with the food. For some foods the predictive value of the RAST test is very high, for others it is lower and not as clear cut as we would like it to be. At times, additional skin testing and in office challenges are required to clarify the significance of a test.

Examples of RAST test significance include:

Egg RAST greater than 7KU/L indicates a 98% chance one will react when eating eggs .

How Is An Antibiotic Medication Allergy Diagnosed

  • A patch test means a small amount of the antibiotic is put on your skin. The area is covered with a patch that stays on for 2 days. Then your healthcare provider will check your skin for a reaction.
  • A skin prick test means a small drop of the antibiotic is put on your forearm and your skin is pricked with a needle. Your healthcare provider will watch for a reaction.
  • An intradermal test means a small amount of antibiotic liquid is put under the surface of your skin. Your healthcare provider will watch for a reaction.
  • A drug provocation test is also known as an antibiotic challenge test. Your healthcare provider gives you increasing doses of the antibiotic medicine and watches for a reaction.
