negative:

Positive:

Tips: oral contraceptives, estrogen, amphetamine, adrenocorticotropic hormone, ethanol, etc., can increase plasma cortisol; intake of drugs such as dexamethasone, levodopa and lithium can reduce plasma cortisol. Normal value

male

15 ~ 20mg / L.

Female

The follicular phase is 17-20 mg/L.

The luteal phase is 16 to 21 mg/L.

During pregnancy (21 ~ 28 weeks) 47 ~ 54mg / L.

(33 to 40 weeks) 55 to 70 mg/L.

Menopause 17 ~ 25mg / L.

Clinical significance

1, elevated in the application of estrogen, oral contraceptives.

2, reduced in ovarian dysfunction, stillbirth, application of androgen.

Low results may be diseases: congenital ovarian hypoplasia, ovarian function deficiency syndrome

Oral contraceptives, estrogen, amphetamine, adrenocorticotropic hormone, ethanol, etc., can increase plasma cortisol; intake of drugs such as dexamethasone, levodopa and lithium can reduce plasma cortisol.

Inspection process
