The doctor will usually order blood tests, an electrocardiogram, urinalysis, and bone densitometry (bone density test) in order to exclude other diseases and to assess the patient's nutritional status.
Many pediatricians order various tests during the first two years depending on the family's history and the child's symptoms, i.e., urinalysis, tuberculin test, and blood tests.
Diagnostic testing will include a complete blood count (CBC), electrolytes (sodium, potassium, chloride) and other blood chemistries, blood urea nitrogen (BUN), and urinalysis.
A complete blood count, various serum chemical and electrolyte tests, and a urinalysis may be helpful in discovering any underlying medical disorders.
The diagnostic evaluation for headache may include blood tests and urinalysis to rule out other medical conditions that may be causing the headaches.
