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, also known as laryngotracheobronchitis, is a type of respiratory infection that is usually caused by a virus.[1] The infection leads to swelling inside the trachea, which interferes with normal breathing and produces the classic symptoms of barking cough, stridor, and a hoarse voice. Fever and runny nose may also be present. These symptoms may be mild, moderate, or severe. Often it starts or is worse at night. It normally lasts one to two days.
