Treating asthma in children under 5

Tests to find and track asthma in young children

It can be a challenge to find out whether a child under age 5 has asthma. The main symptoms can overlap with other conditions. With older children, a healthcare professional can use a breathing test that measures how well the lungs work. But this type of test is not useful with younger children. That's because they may have trouble following instructions and breathing as they're told.

For those reasons, your child's healthcare professional likely will use many pieces of information to figure out whether your child's symptoms are caused by asthma.
