Hormones are substances of protein nature, directly affecting the functioning of the entire human body and regulates all important biochemical processes.
Due to the semi-automatic analyzers can be precisely determine the level of hormones. The key to obtain reliable results is the proper preparation for the examination.
Sometimes conducting such a survey is required urgently, when a person suffers a cold. Against this background, it is often a number of questions: what factors can affect the result of the analysis and whether it is possible to take a blood test for hormones during cold. Blood on hormones in the cold can be taken if there are no complications and temperature.
How cold affects the hormones
According to scientists, a mild form of SARS does not affect hormones, unless there are any complications, accompanied by the reception of individual drugs. However, the laboratory must be aware of the patient's condition at the fence of the biomaterial to be able to get a more accurate picture.
Effect of cough and cold preparations
Despite the fact that the anti-inflammatory as well as anti-viral agents have no effect on the hormones, there are a number drugs (antibiotics, supplements and other means), the use of which can distort results.
Aspirin may also distort the picture. For this reason, screening should be done in 7 days.
Therefore, doctors recommend in such cases to donate blood for hormones in the cold no earlier than 10-15 days after discontinuation of the drug.
Furthermore, if the mild form of SARS research will be authentic, in the event of complications, fever, chills, hormonal parameters may be distorted. In such case should not take hormones until full recovery.
What tests can and can not take
If all of the above rules are observed, to be tested for hormones in the cold as possible. These assays include:
- TSH;
- T4 (free or total);
- T3, in the absence of the temperature of the patient. And if he does not receive antipyretics.
Can not be tested for antibodies to thyroid peroxidase if a cold for a long time does not pass, because results may be unreliable due to the intake of vitamins, medicines.
Terms of delivery of analyzes for colds
It is also important to remember that you need to take hormones early in the morning on an empty stomach. When this is allowed to drink water.
Since the last food intake before the sampling of biological material must be not less than 10 hours.
On the eve of the forthcoming analysis:
- 48 hours prior to the test to stop drinking;
- for 2 hours before the sampling of biological material can not smoke;
- You can only eat a light and non-fried food;
- We need to give up strenuous exercise and sexual intercourse;
- in the case of the use of any drug it is necessary to consult a doctor because some of them may give false results or distort them;
- avoid stress.
Analysis of thyroid hormones is preferably carried out with the appearance of symptoms such as reduced hemoglobin level in the blood, weakness, drowsiness, mood swings, swelling of the thyroid gland.
This assay is undesirable to conduct during viral diseases, since possibly causing false test results. The doctor can cancel the test for this reason. This test is carried out at any time of the day. To avoid or reduce the increase in thyroid hormone levels before blood donation is recommended to cancel the use of drugs that can provoke it.
To obtain reliable results, must pass tests in compliance with all of the above rules and adhering to the basic recommendations.
As for the study of women's hormonal levels, it must be conducted on 7-8 days of the menstrual cycle, and for screening of men - just need to stick to these basic rules and guidelines required for the test.
