Allergy - Basil Test

Basil is a member of the mint family which is used in both fresh and dried ways, and as an extract. It is commonly found in Italian and Indian food items, added to give a distinct flavour. It is also found in chartreuse and other liqueurs. The allergy basil test is performed on a sample of skin to measure the degree and extent of the allergic skin reaction. It is done to assess a further course of treatment for the same.

This test, unlike other common blood tests, does not require fasting. No other special preparation is required, and it is advisable for the test taker to inform their doctor or test provider about any medical conditions or allergies otherwise existing. The doctor must also be informed of any other medications that the test taker is taking, pursuant to which the doctor will give specific instructions. It is advisable that the test taker wears a shirt or t-shirt which exposes the forearm or is loose enough to roll up, as the test site is the forearm.

The test is done to identify if the person is allergic to basil or not. If the results come out positive, the level and extent of the allergy is assessed to decide if merely refraining from consuming basil will suffice or if any medication is required to control it generally. The normal values for an allergic skin reaction to basil is a wheal and flare reaction of at least 3 mm. This applies to both men and women, and across all age groups.

The test type is called skin prick test. Here, a needle is pricked on the forearm of the person with a small amount of the allergen, which is basil in this case. The test is done is specialised allergy testing centers, full service testing centers or at a clinic or hospital. A part of the skin on your arm is chosen as the site, which is cleaned by rubbing alcohol. After this, the needle is injected. The skin is observed for a period of time to see if it shows any reaction to the allergen.
