This test will determine the quantity of 17-hydroxyprogesterone (17-OHP) in your blood monster.17-OHP is the substance that makes your adrenals.
Your adrenals are two small organs on top of each kidney. They make different types of hormones that you need to stay in life. Hormones are considered chemical messengers in the blood that control the effects of certain cells or organs.
Normally, the adrenal glands use 17-OHP to make a hormone called cortisol. Cortisol helps organize the body’s response to energy levels, blood sugar (sugar), blood pressure, stress, illness, and injury.
The 17-OHP test helps diagnose a group of abnormal hereditary genetic disorders that affect how well adrenal cortisol occurs. These genetic disorders of the adrenal glands are called congenital adrenal hyperplasia (CAH).
People with CAH have a genetic change that makes an enzyme necessary to make hormones unavailable; the well-known picture of CAH is caused by the lack of an enzyme called 21-hydroxylase. 21-hydroxylase allows the adrenals to apply 17-OHP to helps to make cortisol.
Without adequate amounts of 21-hydroxylase, the adrenals have difficulty making enough cortisol. Since the adrenals have to work hard to do their job, they grow and make abnormally high amounts of 17-OHP. These high levels of 17-OHP are considered a symptom of CAH with 21-hydroxylase deficiency.
The adrenal glands use the extra 17-OHP to make more male sex hormones than normal amounts. This occurs in boys and adults of both sexes. Therefore, testing for male hormones, including testosterone, is often used in conjunction with the 17-onP test to diagnose CAH.
Symptoms of CAH depend on the number of cortisol levels the adrenal glands can make; CAH is often divided into two groups, depending on how severe the symptoms are.
- Classic CAH includes a form of nonsense fear. Diagnosis is usually made at birth. Without diagnosis and treatment, CAH can be life-threatening. Nonsense symptoms can occur soon after birth. They have a good chance to include
- Dehydration
- Low blood pressure.
- Irregular heartbeat (arithmie)
- Shock
Newborn babies of young women with loom CAH may have external genitalia that are not considered distinctly female or male. This is caused by the highest levels of male hormones. In newborns, the genitalia usually appear normal, but the penis may be more than normal.
Conventional CAH, caused by a deficiency of 21-hydroxylase, can be diagnosed with the 17-ONP test. Less commonly, CAH is caused by a deficiency of another enzyme.
- Boys are more likely to show symptoms of early puberty, i.e., sexual maturation before the age of 8 and before the age of 9 in boys.
- Teenage girls and women are more likely to have more whiskers than normal or bottomless eyes.
- Adults are at increased risk of infertility.
Other names: 17-OH progesterone, 17-OHP, 17 alpha-hydroxyprogesterone, 17-hydroxyprogesterone: serum, progesterone: 17-hydroxy.
What is it used for?
The 17-OHP test is used to detect and monitor the well-known CAH pattern, also known as 21-hydroxylase deficiency. The test is used to
- Screen all newborns for difficult CAH (classical CAH). Screening newborns is not likely to detect the presence of non-severe CAH (non-classical CAH).
- It can help diagnose mild CAH in boys, adolescents, and adults who show signs that symptoms may be the cause.
- Find out if there is a treatment for CAH.
- Help resolve CAH in women who have specific symptoms such as heavy beards and irregular menstruation. These symptoms can be caused by other diseases such as polycystic ovarian syndrome (PCOS).
17-Why is the OOHP test necessary?
Babies need the 17-OHP test as part of the regular newborn screening test to find out if they have a difficult CAH.
- If the baby is delivered in the clinic, the baby will usually have the 17-OHP analysis before going home. The test is more accurate if performed at least 24 hours after birth. If your baby has been tested previously, ask your gynecologist if you can have a second test later. Some states require two tests for all babies.
- If you are delivering at home, make sure your baby has all the necessary screening tests.
Symptoms of CAH usually begin in the first few days or months of life, but in some cases may not be noticed until early adolescence. These symptoms can be severe and include
- Energy deficiency
- Vomiting or other eating disorders
- Diarrhea
- Dehydration
- Stunting (failure to gain weight and grow as expected)
Children, adolescents, and adults may require testing for signs of nonsevere CAH (non-classical CAH).
In children and young adults, signs of non-severe CAH may include
- It increases rapidly and decreases at younger than normal ages. As a result, mature youth and mature adults with CAH are more likely to be shorter than average in height.
- Signs of early puberty.
- Severe acne that may persist into adulthood.
In girls and women, signs of mild CAH may include
- More facial and body hair than normal.
- Irregular or no menstruation at all
- Hair loss on head, especially during sleep (alopecia due to male pattern)
- Enlarged clitoris
- Infertility
Signs of severe CAH in boys and men
- Enlarged penis with small balls (testicles)
- Low sperm cell count.
- Infertility
What happens in the 17-on-p test?
For screening in newborns, the doctor rubs alcohol on the baby’s heel. The doctor then presses the baby’s heel with a small needle to collect a drop of blood. The heel is rotated during this process.
In older children and adult children, a caregiver with a small needle will take blood from a vein in your arm. After the needle is inserted, a small amount of blood is collected in a test tube or vial. As the needle goes in and out, things get a little busier. This usually takes less than 5 minutes.
Need to prepare for the test?
No special materials are needed for the 17-OHP test.
Are there any risks involved in the test?
The risks of blood testing are not sufficient. You can have minor soreness and bruising at the site where the needle was inserted, but most signs disappear quickly. The baby has the opportunity to feel some acceleration when the heel is pressed. Small bruises may form on the heel, but disappear quickly.
What do the results mean?
The results of the 17-OHP test indicate whether you or your baby has the better-known pattern of CAH caused by a deficiency of 21-hydroxylase.
If the test result shows a normal 17-OHP count, this means that you or your baby probably do not have CAH due to 21-hydroxylase deficiency. If you or your baby has signs, your doctor can perform other tests to find the cause.
If the test results show a higher than normal 17-OHP value, you or your baby probably has CAH. Your doctor can do other studies to learn more about the effects of CAH on you and your baby.
If you or your child has been treated for CAH, a decrease in the 17-OHP value means that treatment will begin in a short time. treatment for CAH can consist of medications to change the cortisol that your body cannot regulate. depending on the type of CAH, other medications may still be needed. In some cases. If a woman has atypical external genitalia, surgery is still possible.
If CAH has been established in you, your child, or another family member, you may want to speak with a genetic consultant. Genetic consultants are trained in genetics and genetic testing. They can help you estimate how great the likelihood is that you will pass CHAA on to your future children.
If you have questions about your 17-OHP test results, talk to your own care provider.
Is there anything else I should know about the 17-OHP test?
If the results of the 1-OHP test are not clear, your doctor can order another test to measure 17-OHP. This is called the ACTH Stimulation Test. With this, cortisol and 17-OHP are measured before and after an injection of ACTH (adrenocorticotropic hormone).
ACTH is the hormone that your body prepares your adrenals to produce cortisol; if you have CAH, injecting ACTH will increase your 17-OHP levels but not your cortisol levels.
