A patch test is not performed in the ear canal (A) because this is a sensitive area that may be difficult to accurately measure and may cause discomfort to the patient. In addition, certain products used for patch testing may be harmful if they enter the ear canal.

A patch test is not performed on the forehead (B) because this area is more prone to sweating and irritation, which can interfere with the results of the test.

A patch test is not performed under the foot (C) because this area is typically covered by shoes and socks, making it difficult to accurately read the test. In addition, the skin on the bottom of the foot is thicker and less sensitive, making it less likely to react to potential allergens.

The patch test is performed on the inner bend of the elbow (D) because this area has thin, sensitive skin that is less prone to sweating and irritation. This allows for accurate readings and reduces discomfort for the patient. Additionally, this area is easily accessible for the patient and allows for easy monitoring of any reactions.
