Growth Hormones

Do you lack growth hormone?

The growth hormone tests can assess your pituitary gland function, which may indicate a shortage.

GH tests are used to diagnose illnesses and problems caused by a lack of or excessive production of growth hormone (GH), assess pituitary function, and track the success of GH therapy.

Growth hormone is necessary for a child's appropriate development and growth, and it supports healthy linear bone growth from birth through puberty. GH regulates bone density, muscular mass, and lipid metabolism in adults, albeit it is not as active as in children. Deficiencies can result in lower bone density, lower muscular mass, and lipid imbalances. Adults with too much GH may develop acromegaly, characterized by bone thickening rather than bone lengthening. Skin tags and intestinal polyps can also be caused by too much GH. Acromegaly and gigantism, if left untreated, can result in consequences such as type 2 diabetes, an increased risk of cardiovascular disease, high blood pressure, arthritis, and, in general, a shorter lifespan.

Measurement of GH is primarily of interest in the diagnosis and treatment of various forms of inappropriate growth hormone secretion. Growth hormone measurements in children are used in the evaluation of short stature and help differentiate low GH production from other sources of growth failure. Stimulation and suppression tests are often more meaningful than random measurements.

Test for adrenal function/Addison's Disease


Determination of ACTH is useful in differentiating between primary and secondary adrenocortical hypo- and hyperfunctional disorders: Addison's disease, Cushing's syndrome, adrenal carcinoma, ectopic ACTH syndrome, and adrenal nodular hyperplasia.

Insulin-like growth factor I (IGF-I, or somatomedin C), a protein involved in stimulating somatic growth, is regulated principally by growth hormone (GH) and nutritional intake. IGF-I is transported in serum by several proteins; this helps maintain relatively high IGF-I plasma levels and minimizes fluctuations in serum IGF-I concentrations. Measuring IGF-I is useful in several growth-related disorders. Dwarfism caused by deficiency of growth hormone (hypopituitarism) results in decreased serum levels of IGF-I, while acromegaly (growth hormone excess) results in elevated levels of IGF-I. IGF-I measurements are also helpful in assessing nutritional status; levels are reduced in undernutrition and restored with a proper diet.

During pregnancy and postpartum lactation, serum prolactin can increase 10- to 20-fold. Exercise, stress, and sleep also cause transient increases in prolactin levels. Consistently elevated serum prolactin levels (>30 ng/mL), in the absence of pregnancy and postpartum lactation, are indicative of hyperprolactinemia. Hypersecretion of prolactin can be caused by pituitary adenomas, hypothalamic disease, breast or chest wall stimulation, renal failure or hypothyroidism. A number of drugs, including many antidepressants, are also common causes of abnormally elevated prolactin levels. Hyperprolactinemia often results in galactorrhea, amenorrhea, and infertility in females, and in impotence and hypogonadism in males. Renal failure, hypothyroidism, and prolactin-secreting pituitary adenomas are also common causes of abnormally elevated prolactin levels.

Prolactin is a single-chain polypeptide hormone secreted by the anterior pituitary under the control of prolactin-releasing factors. These inhibiting and releasing factors are secreted by the hypothalamus. Prolactin is also synthesized by the placenta and is present in amniotic fluid. Prolactin initiates and maintains lactation in females. It also plays a role in regulating gonadal function in both males and females. In adults, basal circulating prolactin is present in concentrations up to 30 ng/mL. During pregnancy and postpartum lactation, serum prolactin can increase 10- to 20-fold. Exercise, stress, and sleep also cause transient increases in prolactin levels. Consistently elevated serum prolactin levels (>30 ng/mL), in the absence of pregnancy and postpartum lactation, are indicative of hyperprolactinemia, which is the most common hypothalamic-pituitary dysfunction encountered in clinical endocrinology. Hyperprolactinemia often results in galactorrhea, amenorrhea, and infertility in females, and in impotence and hypogonadism in males. Renal failure, hypothyroidism, and prolactin-secreting pituitary adenomas are also common causes of abnormally elevated prolactin levels.

The Thyroid-stimulating Hormone (TSH) Blood Test is for differential diagnosis of primary, secondary, and tertiary hypothyroidism. The TSH test is also useful in screening for hyperthyroidism. This assay allows adjustment of exogenous thyroxine dosage in hypothyroid patients and in patients on suppressive thyroxine therapy for thyroid neoplasia.



About 1 in 6,000 children and nearly 50,000 total adults in the United States suffer from a growth hormone deficiency.

Have you ever wondered: "am I growth hormone-deficient?"

A growth hormone deficiency can be a dangerous medical condition if not diagnosed and treated correctly. If you're not sure if you have one, you should get a growth hormone test right away to be sure!

Keep reading to learn everything you need to know about growth hormone tests.

What Is the Growth Hormone Deficiency?

A growth hormone deficiency (GHD) is when your pituitary gland is not producing enough of the growth hormone the body needs. 

Most commonly found in children, a growth hormone deficiency is almost always congenital. This means that you would be born with it. It is possible that it could be due to trauma, called Acquired GHD, or Idiopathic GHD, which is when a patient's GHD has no apparent cause.

Growth hormone lab tests are the only way to be certain that GHD is what is happening within the body.

Risk Factors and Causes of Growth Hormone Deficiency

Most of the time, the cause of a growth hormone deficiency is due to a genetic disorder for GHD. Deficiency in children is more common than in adults, as most are born with it. Idiopathic GHD most likely has been present from birth and has gone unnoticed. 

However, if it is developed later in life, it may be the result of trauma, infection, radiation therapy, or tumor growth within the brain. Usually, this tumor growth is near the pituitary gland.

Signs & Symptoms of Growth Hormone Deficiency

In infants, the first sign a pediatrician will look for is delayed growth. Low blood sugar and abnormally sized genitals can also be one of the first signs. Delayed bone growth, facial structure growth abnormalities, and other signs are also common in infants and children. 

An essential period is during the first 6-12 months of life. Your pediatrician will make sure that the growth rates are normal and haven't decreased more than 10 percent. 

In adults, GHD will present itself as increased fat in the abdomen with decreased muscle mass. Depression, anxiety, low energy levels, poor concentration, and abnormal LDL Cholesterol levels can also be signs of GHD. 

Get a Diagnosis: Growth Hormone Tests

A phlebotomist will draw blood for a growth hormone stimulation test. The blood samples will provide a biomarker level in the test results that will read normal, low, or high.

The phlebotomist will collect a blood sample for your growth hormone blood panel. The lab will test GH levels and an insulin-like growth factor, and a Z Score in females.

Abnormal levels in these tests will indicate a growth hormone deficiency or normal levels of the hormone.

Treatment & Prognosis

Treatment for anyone with GHD is going through hormone replacement therapy. The hormone replacement is injected into a fatty area of the body. The GH levels will continue to be monitored via blood tests and medication adjusted accordingly.

In children, their hormones will be increased around puberty and will taper off once the body can make enough of its own growth hormone. Treatment could last for their entire life, as everyone's body is different. Adults will likely have hormone replacement for the entirety of their lives.

People with GHD can live a normal lifestyle as long as their hormones are monitored and replacement therapy is adjusted as needed.

Frequently Asked Questions Regarding Growth Hormone Deficiency

As with any medical condition, GHD comes with a lot of questions. These are the most commonly asked questions about growth hormone deficiencies.

What Causes Growth Hormone Deficiencies?

Growth Hormone Deficiencies are usually congenital, but they can also be caused by trauma or a tumor growth on the pituitary gland. There are also instances where a cause is not found. 

Am I Growth Hormone-Deficient?

If you are experiencing symptoms of adult-onset GHD, including increased belly fat, abnormalities in cholesterol levels, decreased muscle strength, or another symptom, then it is worth talking to your doctor or ordering the tests yourself through Ulta Lab Tests.

If you believe your child has a growth hormone deficiency, you should get them a test right away to help monitor their symptoms.

Where Can I Get a GH Test?

You can search for a patient service center on our website. We have locations in every state in the US, with the exception of New York, New Jersey, and Rhode Island.

How Is GHD treated?

GHD is treated by hormone replacement therapy. This is a shot usually given daily.

Can You Cure GHD?

GHD isn't considered curable. It is treated until the body can make appropriate levels of its own growth hormone.

How Common Are Growth Hormone Deficiencies?

Growth hormone deficiencies are found in about 1 in every 6000 babies. About 50,000 adults in the United States have a growth hormone deficiency. 

What Are the Side Effects of Grown Hormone Replacement?

Side effects of growth hormone replacement therapy can include high cholesterol, low blood sugar, enlarged heart, muscle and nerve pain, swelling of the arms and legs, and more. Know that if your doctor has decided that growth hormone replacement therapy is right for you, they have decided that the risks outweigh the damage that may be done without the therapy. 

What Does the Growth Hormone Do in Adults?

In adults, the growth hormone helps regulate body fat, muscle mass, and cholesterol levels. It is also necessary for proper brain function.
