Is it possible to brush your teeth before donating blood for hormones, for sugar, before FGDS, gastroscopy

Whether it is possible to brush your teeth before donating blood is a serious and difficult question. A blood test is a method by which an accurate assessment of the general state of human health can be delivered, therefore, such an important procedure must be treated with full responsibility.

Before you go to the examination, you must familiarize yourself with the rules of preparation for it.

Briefly about the procedure

It is very important that the results are not distorted in the process of researching analyzes.

The procedure can be carried out in 2 ways:

1. A general blood test is carried out by taking a biological material from a finger. It shows the exact level of hemoglobin, red blood cells and sugar levels.
2. Vein sampling - a deeper study. With its help, you can find out: coagulability, Rh factor, blood group, determine hormonal levels, the presence of antibodies, biochemistry.

When picking up, there are certain rules that are not recommended to be violated. Otherwise, the results can be skewed, leading to the appointment of ineffective treatment. Therefore, the delivery of biological material must be approached with all responsibility.

Understanding the preparation for different types of examinations

UAC and biochemistry

The use of toothpaste has a particular effect on the result of the CBC. Its use can directly affect it far from being for the better for the patient.

It is the composition of the toothpastes that is the reason for refusing them before some analyzes.

From the synthetic antibacterial drugs triclosan and chlorhexidine, which are in most of the pastes, blood parameters depend, for these substances microflora does not matter, is it useful or harmful. When donating blood for biochemistry, you need to do without tooth brushing. Antibacterial components penetrate into saliva, and then into digestion and blood.

An undesirable component for a blood test - sodium lauryl sulfate - is also included in toothpastes. It is also incorporated into various detergents and cleaners to create a foamy consistency when used. This foam helps to get rid of dental plaque by breaking down deposits on the enamel. However, this substance affects the proteins in the blood and forms compounds that distort the accuracy of the study.

The reagents used to get the results are far from the best. The most accurate result can be only if all the rules of delivery are observed. By the way, in other countries it may be allowed to brush your teeth before donating blood, which is explained by the differences between Russian and foreign research methods, analyzes and reagents.

Before general analysis and biochemistry, it is also impossible:

• consume alcoholic and carbonated drinks;
• take food 12 hours before the procedure, stop eating fried and fatty foods a few days before;
• use medications (if it is impossible to temporarily stop using them, notify a medical professional and a doctor);
• chewing gum.

It is forbidden to drink water in some cases. This is explained by the fact that the water content in the blood can affect the glucose level and the concentration of leukocytes. This must be taken into account. Failure to comply with the rules threatens to re-prescribe biochemistry.

The rules may differ for different analyzes, but in general they are the same for everyone.

For sugar

The analysis for sugar can be submitted several times a day, this method allows you to more accurately estimate the amount of sugar. It should be remembered that the sampling is done only on an empty stomach. You need to pay special attention to this point. In addition to the general rules of preparation, you should reduce physical and eliminate emotional stress. It is advisable to stop smoking during this period.

Before donating blood for sugar and the day before, you should also not use toothpastes. Saccharin, flavoring agents and sweeteners, which they contain, give the pastes a pleasant aftertaste. All of these have an effect on blood glucose.

Although there is little chance of sugars entering the bloodstream when brushing your teeth, some doctors strongly recommend that you do not perform the procedure while preparing for the procedure.

For hormones

During the preparation period, it is allowed to use non-carbonated water in the required amount. Before donating blood for hormones, you should not drink tea, coffee, juices. At this time, it is prohibited to take medications and eat food containing iodine.

For those who are wondering if it is possible to eat before hormone tests, the categorical answer is no. In order for the indicators to be accurate, you cannot even eat or drink tea.

The preparatory period includes emotional and physical peace. You should know that the definition of the hormone of the adrenal glands is given only in the morning and no later than 10.00 h. For the hormone prolactin, blood is donated within 2 hours after waking up.

Brushing your teeth before submitting biological material for hormones is allowed.

The composition of the toothpaste and the presence of sugars in it do not affect the result of this study. The only exception can be toothpaste containing iodine in its composition. Such a tool must be abandoned.

Before gastroscopy

Three days before EGD and gastroscopy in general, you need to stop eating chocolate, seeds, nuts. Also, you cannot eat before the procedure itself, or rather, at least 12 hours before it. During this time, the food will be digested and the picture of the state of the digestive organs will not be distorted. At the expense of water, there is no such prohibition; in 2-3 hours you can drink some pure plain water.

It is important to know whether it is possible to brush your teeth before gastroscopy and, in particular, gastric EGD.

If the study is scheduled for the morning hours, brushing your teeth in the morning is not recommended. The substances that make up the pastes can negatively affect the acidity level of gastric juice. If, during the procedure, the patient takes an analysis for the culture tank, the toothpaste that has got into the blood and stomach can affect the distortion of the result.

It is also important to know what tests need to be passed before undergoing gastroscopy. Usually this is a clinical and biochemical study of blood, its study for infections, as well as OAM.

Other studies

General requirements are suitable for preparing for other examinations. Such studies include:

• determination of the Rh factor and blood group;
• immunological research;
• coagulability;
• helminths;
• onco cameras;
• blood for PCR.

The preparation for donating blood directly relates to the emotional and physical state of the patient. It is desirable that during this period a person feels satisfactory in these areas.

How to deal with oral hygiene

If it is forbidden to brush your teeth, hygiene rules should not be forgotten. It is recommended to carry out a high-quality double brushing of your teeth the day before. An unpleasant odor in the morning can be removed with a few drops of hydrogen peroxide dissolved in water. You need to rinse the mouth with this solution, the main thing is not to swallow it.

The easiest way to maintain oral hygiene is to rinse it with boiled water.
