Hormones are substances that are produced by endocrine glands (thyroid, pancreas, gonads, pituitary, etc.) and participate in all processes in the body. These bioactive compounds determine the processes of growth, development, reproduction, metabolism, the appearance of a person, their character, and their behavior depend on them.
The produced hormones go into the blood, where they are in certain concentrations and equilibrium with each other. Anomalies affect health and can lead to the defeat of various organs and systems. And it’s important not just the concentration of a hormone, but also its relationship to other types of hormones.
When is the blood test prescribed for hormones?
The blood test to determine the level of certain hormones and the hormonal background as a whole can be prescribed by almost any specialist:
- A neuropathologist;
- Oncologist, etc.
This procedure allows you to identify a large number of different pathologies, even in the early stages prior to the manifestation of clinical signs.
The reason for this analysis may be suspected dysfunction of the glands of internal secretion or an increase in the size of the glands (eg, after ultrasound). Frequently check the number of hormones required if:
- increase in weight
A repeat study can be assigned to evaluate the effectiveness of the treatment.
Preparing for the analysis of blood for hormones
To obtain high quality and reliable results should follow the recommendations set forth below for the analysis of blood for all hormones (thyroid-stimulating hormone (TSH), sex, adrenals, thyroid, etc.):

Decrypting the blood test for hormones can only be done by a qualified specialist who bases each patient on an individual approach, taking into account the characteristics of the organism, existing diseases, current therapy, and many other factors. It should be noted that the standards for the analysis of blood for hormones in different laboratories are different. This is due to the fact that different methods, equipment, reagents, holding time, etc. can be used in the study. Therefore, if you need to conduct repeated analyzes, you should contact the same institution as you did for the first time, and in deciphering you should follow the standards used.
Analysis For Hormones In Women
To determine and timely treatment of gynecological diseases in women often prescribed analysis of hormones. In this case, the most commonly performed determination of the level of luteinizing hormone, progesterone, prolactin.
Luteinizing hormone (LH) belongs to adrenal hormones synthesized by the anterior pituitary gland. It is this hormone that stimulates the production of estrogens in the female body and regulates the secretion of progesterone and is directly involved in the formation of the yellow body.
Such an analysis for female sex hormones is mandatory if:
- Decreased libido;
- Polycystic Ovary Syndrome;
- Sexual Infantilism

Blood is only taken on an empty stomach and on the 7th day of the menstrual cycle.
Normal indicators of this hormone for women differ and depend on the phase of the menstrual cycle. Thus, in the follicular phase, its concentration is 1.1-11.6 mU/ml, in the ovulation phase – 17-77. In the luteal phase, the concentration level does not exceed 14.7. It should also be noted that the intake of oral contraceptives reduces the level of this hormone to 8.0 mU/ml.
What is an analysis for progesterone?
Among the analyzes for female hormones, most often an analysis is performed to determine the level of progesterone in the blood. It is produced directly by the yellow body and is acutely necessary for the normal course of pregnancy. Progesterone prepares the preparation of the uterine endometrium, with which the fertilized egg can be implanted.

the hormone levels are different: 0.32-2.23 nmol / L – in the follicular phase and 6.99-56.63, – of the luteal.
What is the purpose of analyzing prolactin in the body?
The hormone prolactin participates directly in the process of formation and development of the mammary glands and stimulates the production of milk them during lactation.

Thus, which tests are also performed for female hormones, a preparatory preparation for them is necessary.
