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.
Croup is an illness caused by a virus in which one part of the air passage to the lungs becomes swollen and narrow. Because of the swelling, when your child breathes in he makes a hoarse, raspy sound. Also, your child may have a strange cough that sounds like a barking seal. Croup may last many days, but the worst part is usually over in two to three days. It is usually worse at night.
