Transferrin saturation is a calculated value resulting from a medical laboratory test to measure the amount of iron bound to transferrin in the blood. The liver produces transferrin, which is a protein that serves to bind iron molecules and carry them through the bloodstream to the bone marrow.
In addition to the cough, your child may also have a hoarse voice and have laboured breathing. Croup is most common in autumn and winter, and when a child is between 6 months and 3 years old. However, older children up to 15 years old sometimes get croup too. Croup is a common respiratory condition in children caused by either a viral infection or allergy.
Around 3% of children get croup each year, usually during autumn and winter. Children aged from 6 months to 3 years old are most likely to get croup, but older children can be affected. A GP will usually diagnose croup from the child's symptoms and recommend treatment at home.
