A new patch of irritated, inflamed, or red skin might make you want to turn to Google Images for help determining the cause. But it’s important to evaluate skin abnormalities thoughtfully and seek medical attention if you’re unsure.

Rashes are a visible sign of a medical condition or a reaction to an irritant, medication, or infection. They can be a harmless manifestation of acne or a mild irritant, or they may indicate a more serious medical issue, like an allergic reaction or autoimmune disease.1

To determine the cause of a rash, pay attention to where it's located, how quickly it spreads, and what it looks and feels like. Also, look for other signs of illness in your body. Take this quiz to help you identify the signs of a serious rash.

About This Quiz

This quiz will ask questions about your rash and help you determine when it’s time to see a provider.

Certain signs indicate a rash may be part of a serious health problem that requires medical attention. However, many rashes may not appear as serious as they are, and vice versa. When in doubt, always call a trusted health provider.

Diagnosing a Rash

Rashes come in many shapes and sizes and look different depending on skin tone. Sometimes, you’ll see small blisters or bumps. Other times, rashes appear as large patches of scaly, itchy skin.

A dermatologist or other healthcare provider may not be able to diagnose the cause of a rash without seeing it in person.

Simply examining the rash can provide a doctor with information about its potential cause. Many rash-causing conditions have characteristic symptoms and respond easily to treatment.  

Still, some rashes may require a biopsy or a sample to be analyzed in a lab. This can help determine the cause of the rash and identify the most effective treatments.2
