Animal dander, house-dust mites, cockroaches, pollens and outdoor moulds, tobacco smoke and indoor pollens are common asthma triggers.

What action can you take to avoid or eliminate them?

One of the first step in controlling and managing your asthma, is to identify and avoid these triggers.

Asthma allergens can be identified by a skin prick test (SPT) or by a blood test known as the RAST test.

These tests to identify your asthma allergens can be done from an early age. The notion that an infant's allergens can only truly be identified from the age of three, is not true.

These tests can be done with great benefit on infants of six months.
