Hormones are produced by male and female sex organs, thyroid and adrenal glands, with blood spread throughout the body, regulate the general state of health, the physiological and psychological activity. The concentration of biologically active substances affects the patient's lifestyle, diet, chronic diseases, emotional or physical stress. Therefore, the accuracy of the results and the detected deviations treatment depends on proper preparation for the delivery of blood to hormones.
General rules for the preparation
The analysis on hormones will be as accurate as possible, if we exclude all factors that may distort the result, and the recommendations of physicians:
- 10-14 days prior to blood sampling to stop taking any drugs that including oral contraceptives. If this is not possible, for whatever reason (eg, the patient has to take daily medication for chronic conditions), it is necessary to inform the treating physician.
- 3-5 days to give up sweets, fried, smoked and fatty foods, fast food, alcoholic and carbonated beverages, and exercise power. People go to the gym, swimming pool or fitness center, exercise should be postponed for a few days until the blood on hormones will not be dealt.
- For 2-3 days prior to visiting the laboratory to rule out any diagnostic procedures - X-rays, chest X-rays, ultrasound, MRI, CT scan, etc.. Not recommended for physical therapy - either in the clinic or at home.
All assays were performed in the first half of the day - up to 10-11 hours in the morning. Donating blood only need an empty stomach - the last meal should be 12 hours or more to visit the laboratory. The more time fasting - the better the result. On the day before the delivery of blood can not drink coffee or black tea, smoke, do gymnastics, for a morning jog. It is desirable to give a gum, and even from a dentifrice with a powder or paste.
The correct preparation for analysis of hormones depends on the accuracy of the study. To accurately diagnose the condition in hormonal levels, the clinic should come in advance. Before sampling should be 15-20 minutes to sit in the hallway to catch my breath after walking and lifting on the floor, take it easy and relax. It is undesirable to actively communicate with other patients argue and nervous.
If all of the recommendations have been followed, but in the blood donation day in a woman or a man has a fever, sample is collected can not be done. Contraindications to the investigation are any inflammations, bacterial and viral infection accompanied by fever or chills.
How to prepare for the delivery of thyroid hormones
Thyroid function endocrinologists evaluated on several parameters, prescribed to donate blood for:
- TSH - thyrotropin;
- T4 - free thyroxine;
- T3 - triiodothyronine;
- ATTG - antibodies to thyroglobulin.
If the patient is taking iodine-containing hormones or drugs to pass the tests for thyroid hormones is necessary to prepare in advance:
- 3-4 days to stop drinking medicine with iodine;
- 21 days to stop taking medication with synthetic thyroid hormones.
If the patient has undergone a full course of hormone replacement therapy, controlling sampling should be performed not earlier than 30 days after the last pill.
It is important not to be nervous, to avoid physical and mental overload, observe the recommended diet. When preparing to give blood for thyroid hormones are allowed to be sexually active. Women of childbearing period tested for TSH, ATTG, T3 or T4 can be any day of the menstrual cycle.
Preparation for analysis on hormones
Analyzing the level of sex hormones in the blood, it is possible to accurately determine fetal development, the state of a pregnant, infertility and other diseases.
For men, there are no restrictions on the delivery of the analysis on hormones.
And women conducting analyzes on hormones in gynecology appointed depending on the menstrual cycle:
| Title | day of the menstrual cycle, the recommended sampling |
| Follicle stimulating hormone (FSH) | 5 — 7 |
| Luteinizing hormone (LH) | 5 — 7 |
| Progesterone | 22 - 23, if other terms are not specified doctor |
| 17-OH Progesterone | 5 - 7, if other terms are not specified doctor |
| estradiol | 5 - 7, if other terms are not specified doctor |
| prolactin | 5 - 7, if other terms are not specified doctor |
| DHEA-sulphate | Any |
| Testosterone | Any |
One day before the date of the prolactin blood women are not recommended to attend bath or sauna, take a hot bath. In just a few days prior to blood sampling to female hormones to properly and balanced feed, give up bad habits, take care of the emotional and physical health. In preparation for the delivery of a blood test for hormones in gynecology, it is necessary for 24-48 hours before the appointed time to eliminate any sexual contact, viewing erotic materials (magazines, movies).
Preparation for the analysis of adrenal hormones
The adrenal glands produce several groups of biologically active substances:
- mineralkortikoidy (aldosterone, corticosterone and deoxycorticosterone);
- cortisol;
- catecholamines (adrenaline and noradrenaline);
- androgens.
In preparation for analysis a few days before the planned study should be excluded from the diet:
- chocolate and chocolates;
- hard and soft cheeses;
- chicken and quail eggs;
- tomatoes;
- bananas;
- pineapples;
- coffee;
- cocoa;
- Black tea.
The maximum concentration of adrenal hormones is determined early in the morning, so it is desirable to take the sample from the opening of the laboratory and not later than 10 o'clock in the morning. The results will be more accurate if within 3-5 days before delivery of analyzes on hormones the patient will have peace of mind - not conflict with family, colleagues or neighbors, to avoid arguments and resolution of all disputes transferred to the time of collection blood.
Which could affect the accuracy of the results
The accuracy of laboratory testing with blood tests for hormones affect different factors:
- the use of drugs;
- meal;
- physical exhaustion;
- emotional and mental overload;
- bad habits (alcohol, smoking, drugs);
- Times of Day;
- conduct physical therapy, X-ray, ultrasound and other surveys for a few days before sampling;
- phase of the menstrual cycle (on hormones of the female reproductive system).
Compliance with medical recommendations to prepare for a blood test is the guarantee to obtain reliable results. Their accuracy can also affect the different methods used in different laboratories. In order to reliably assess the state of hormonal, endocrinologists, gynecologists and andrology are advised to take the sample in the same place.
