What is a patch test given to determine?

Hair color levels
A possible sensitivity to aniline derivatives
The percentage of body water
Product service familiarity

The correct answer is: A possible sensitivity to aniline derivatives

The patch test is not used to determine hair color levels, as that can be assessed through other means such as a color consultation with a stylist. It is also not used to measure the percentage of body water, as that can be measured through other methods like a body composition analysis. Lastly, the patch test is not used to assess familiarity with a product or service, as it is specifically designed to determine if a person may have a sensitivity to aniline derivatives. These are chemicals commonly found in hair dyes and other products. Therefore, option B is the correct answer as it provides an accurate explanation of the purpose of a patch test.
