 |
The growth hormone(GH) stimulation test measures the level of growth hormone(GH) in the blood after you receive arginine or GH-releasing hormone. The test measures the ability of the pituitary gland to release GH.An angiocatheter(IV) is usually pl...

|
The growth hormone test measures the amount of growth hormone in the blood.Blood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine(antiseptic).
|
|
Tests for growth hormone include Somatotropin hormone test, Somatomedin C, Growth hormone suppression test(glucose loading test), and Growth hormone stimulation test(Arginine test or Insulin tolerance test).Growth hormone tests are ordered for the...

Growth hormone tests measure the levels of specific hormones that regulate human growth. These hormone levels are measured in blood serum samples obtained by venipuncture.

The brain is a large mass of soft nervous tissue made up of both neurons and supporting glial cells lying within the cranium of the skull. The brain contains both gray and white matter.
|
 |
Magnetic resonance imaging(MRI) scanners rely on the principles of atomic nuclear-spin resonance. Using strong magnetic fields and radio waves, MRI collects and correlates deflections caused by atoms into images.
|
|
Traumatic brain injury(TBI) is the result of physical trauma to the head causing damage to the brain. This damage can be focal, or restricted to a single area of the brain, or diffuse, affecting more than one region of the brain.
|

 |
A brain tumor is an abnormal growth of tissue, either malignant(cancerous) or benign(noncancerous), in the brain. Each year, more than 17,000 brain tumors are diagnosed in the United States.A benign brain tumor is composed of slow-growing noncance...

Congenital brain defects are a group of disorders of brain development that are present at birth.Brain development begins shortly after conception and continues throughout the growth of a fetus. A complex genetic program coordinates the formation,...
|
 |
Like all other parts of the body, the brain and central nervous system are made up of cells that ordinarily grow and divide to create new cells as needed. This is usually an orderly process; but when cells lose their ability to grow normally or to...
