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.
Symptoms of croup are often worse at night and when a child is upset or crying. The same viruses that cause the common cold also cause croup. Most often seen in the fall, croup can affect kids up to age 5. There are two types of croup, viral croup and spasmodic croup, both of which cause the barking cough. Most cases of croup are viral.
