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.
Younger children are more affected by croup because their airways are smaller. Therefore, a small amount of swelling can make it really hard for a child to breathe. Croup is most commonly seen in children 3 months old to 5 years. The peak time for croup to occur is 2 years old.
