What is a 17-hydroxyprogesterone blood test for?
17-OHP is made as part of the process of producing cortisol. A 17-OHP test helps diagnose a rare genetic disorder called congenital adrenal hyperplasia (CAH). In CAH, a genetic change, known as a mutation, prevents the adrenal gland from making enough cortisol.
What does low 17-hydroxyprogesterone mean in adults?
Low values of 17-OHP are found in adrenal hypofunction, whether of adrenal or hypothalamic/pituitary origin. The most frequent cause of a low 17-OHP concentration is suppression of the pituitary–adrenal axis by synthetic glucocorticoids given therapeutically.
What should my 17-hydroxyprogesterone level be?
In general, normal results are as follows: Babies more than 24 hours old – less than 400 to 600 nanograms per deciliter (ng/dL) or 12.12 to 18.18 nanomoles per liter (nmol/L) Children before puberty around 100 ng/dL or 3.03 nmol/L. Adults – less than 200 ng/dL or 6.06 nmol/L.
What is the normal range for hydroxyprogesterone?
Reference Range Reference ranges of serum 17-hydroxyprogesterone (17-OHPG) are as follows [1, 2, 3] : Cord blood: 1000-3000 ng/dL. Newborns: < 630 ng/dL (> 630 ng/dL may be seen in preterm infants, but > 1000 ng/dL is uncommon) Prepubertal males: < 110 ng/dL.
Why is my 17 hydroxyprogesterone high?
High levels of 17-OH progesterone can indicate a condition called congenital adrenal hyperplasia (CAH). CAH is a glandular disorder that results in the adrenal glands being unable to create sufficient cortisol, and it may increase the production of male sex hormones called androgens.
Can 17-hydroxyprogesterone be too low?
Normal 17-OHP results mean that it is likely that the person tested does not have CAH due to a 21-hydroxylase deficiency. Low or decreasing concentrations in a person with CAH indicate a response to treatment. High or increasing levels may indicate that changes in treatment are required.
Why is my 17-hydroxyprogesterone high?
Is a progesterone level of 17 good?
Normal test results In general, normal serum progesterone test results fall in the following ranges: men, postmenopausal women, and women at the beginning of their menstrual cycle: 1 ng/mL or under. women in the middle of their menstrual cycle: 5 to 20 ng/mL. pregnant women in their first trimester: 11.2 to 90 ng/mL.
Can a woman with CAH get pregnant?
Women with classic CAH can conceive while on routine maintenance therapy, and it is estimated that 80% and 60% of women with simple-virilising and salt-wasting forms of CAH, respectively, are fertile. Most women who are compliant with maintenance therapy have ovulation rates as high as 40%.
Is 17-OHP an androgen?

What is normal range for progesterone level?

What is 17 OH progesterone?
17α-Hydroxyprogesterone, also known as 17-OH progesterone, or hydroxyprogesterone, is an endogenous progestogen steroid hormone related to progesterone. It is also a chemical intermediate in the biosynthesis of many other endogenous steroids, including androgens, estrogens, glucocorticoids, and mineralocorticoids, as well as neurosteroids.
How does progestin affect body?
Dr Philippa said: “Progesterone is sometimes considered a sleep hormone “The falling levels of oestrogen in the body affect the nails making them more dehydrated.” It’s easy for women to brush off their aches and pains as just part of old age.
