DYNAMIC HORMONE STIMULATION TESTING
COPEDS can perform dynamic hormone stimulation testing in our office if your child needs it. Stimulation testing is performed to assess the endocrine glands (and in particular the pituitary gland), which play key roles in controlling many body functions. Minor abnormalities of the endocrine glands (as a result of congenital problems or organic disease) can cause major disruptions of normal growth, pubertal development, glucose control, and water balance in the developing child.
The stimulating agents and testing conditions of this evaluation are associated with a strict clinical protocol in order to obtain valid and meaningful results. Testing is performed in the morning, on an empty stomach, for up to 4 hours, depending on the gland being evaluated. An intravenous line (IV) is placed in the child's arm for serial blood sample collection. COPEDS has a private room for the testing, along with a wide selection of movies to help pass the time. In very young children, the testing occasionally requires an in-patient admission and overnight evaluation. In older children and adolescents, these tests are performed in our office with one-on-one evaluation and monitoring by a COPEDS provider.
Examples of stimulation evaluations performed at COPEDS include:
- Growth hormone
- Adrenal insufficiency evaluation
- Congenital adrenal enzymatic defects
- Glucose intolerance
- Dysmetabolic syndrome
BODY COMPOSITION ANALYSIS (MEDGEM)
COPEDS can measure body composition in our office with the MedGem® indirect calorimeter if your child needs this. The MedGem indirect calorimeter is a FDA 510K-cleared Class II medical device that accurately measures oxygen consumption (VO2) to determine resting metabolic rate (RMR). Your RMR is the amount of calories (energy) your body uses each day without activity. RMR varies from person to person. Getting your RMR measured can provide important information to help you achieve your nutrition and weight goals. The MedGem® measurement is obtained while fasting and in a quiet and relaxed environment wearing a nose clip and breathing into a mouthpiece over a 10-15 minute period. The results will be used to determine what type of body composition your child has and what types of foods and exercises are best for weight loss. From COPEDS experience, the addition of metabolic personalization to a weight loss plan is a key ingredient for success. More about MedGem from other weight loss experts in this video:
BONE AGE FILMS
COPEDS can perform bone age radiographs in our office if your child needs one. Development of the bones of children occurs in a set pattern characterized by a progressive uptake of calcium in a discrete pattern. With an x-ray of the hand, we can obtain a bone age that compares a child's growth pattern with tat of a known standard. This allows us to determine if growth and development are occurring at an appropriate pace.
COPEDS can perform a thyroid ultrasound in the office if your child needs one. Ultrasounds use sound waves to image the thyroid. There is no radiation exposure. The sound waves are emitted from a small hand-held transducer that is passed over the thyroid. A lubricant jelly is placed on the skin so that the sound waves transmit more easily through the skin and into the thyroid and surrounding structures. This test is quick, accurate, cheap, painless, and completely safe. The results can be known almost immediately.
Both Dr. William Zipf and Dr. Jennifer Dyer have been trained by the American Association of Clinical Endocrinologists in thyroid ultrasonography.
