How long should you wait to check results after a patch test?

12 hours
18 hours
24 hours
48 hours

The correct answer is: 24 hours

After conducting a patch test, it is essential to wait for 24 hours before checking the results. This waiting period allows enough time for the skin to react to the substances applied during the patch test fully. Checking the results too soon may not accurately reflect whether there is an allergic reaction or sensitivity to the product. Therefore, waiting for 24 hours ensures a thorough and reliable assessment of the skin's reaction.
