Does the PCR test for coronavirus surrendered on an empty stomach or not? What can and what can not be done before the PCR test on coronavirus?

The PCR test for coronavirus surrenders according to the rules. If they are not observed, the result will be false negative.

PCR Test - This is a molecular diagnosis to determine the presence of the pathogen, determines it even in the presence of several DNA molecules. This method has passed long clinical trials and has established itself as the most accurate and fast diagnostic method that does not require labor -intensive microbiological studies. It is necessary both to identify the disease and before vaccination, to give 100% The result of the absence of the virus in the body of the vaccinated.

To conduct a successful analysis, it is necessary to explain the rules of the procedure and the proper fence of the material to ensure the objectivity of the PCR test. Below we will tell you what rules exist and how this analysis is given. Read further.

PCR-Test for Covid: Where do they get the analysis-from a pharynx or nasopharynx?

Coronavirus infection (Covid-19) - This disease refers to respiratory (inflammatory diseases of the upper and lower respiratory tract). Infection occurs through the nasal and oral cavity, airborne, in contact, when coughing or sneezing an infected person nearby. Therefore, analysis PCR-Test for covid It is taken from a pharynx or nasopharynx, it will be more accurate when the two strokes taken mixed in the test tube.

Where is the analysis of the PCR test for coronavirus, Covid-19?

There are several options where you can take the analysis PCR test To the coronavirus, Covid-19. Here are some of them:

Polyclinic at the place of residence. The test will be made for free:

• If you have signs of a cold or Covid-19.
• Contacted with the patient Kovid-19 and you have signs of SARS and influenza.
• All medical workers in contact with patients with the risk of infection.
• Citizens who have arrived in the Russian Federation with signs of colds.

The preliminary record is not needed, the reception is carried out in the order of a live queue. You need to have passport, compulsory medical insurance, SNILS. If the receipt of the PCR test is connected with going abroad, then information from the passport will be required. They will be reflected in the certificate with the result of the analysis. For citizens of foreign states, a document confirming the legality of stay in the Russian Federation, a state passport and foreign countries are required. If the PCR test for the child, the birth certificate and the compulsory medical insurance policy (compulsory medical insurance) are necessary, the test is carried out only in the presence of parents.

Express test. You can make in special points located in shopping centers, railway stations, MFCs (multifunctional centers of public services), airports, medical centers. You can find out the address of the points close to you by calling the hotline by calling 8-800-2000-112.

Express test for independent conduct. You can buy in a pharmacy and do it yourself. This method is based on immunochromatographic analysis, resembles pregnancy tests. Covid express test, reveals an infection in asymptomatic media. The smear is taken from the nasal cavity, the result after 15 minutes. The procedure is painless. A negative result will not change your lifestyle. A positive result will require confirmation, it is necessary to pass the PCR test, the analysis will be ready within three days. Before receiving the result, it is required to be on self -isolation. He will go to your clinic and SMS message will come to the phone number. If the result is «+», you need to stay at home and expect the doctor’s arrival. Treatment will be prescribed and, if necessary, a sick leave is issued.

How is the PCR test for coronavirus, Covid?

The set for performing the test is individual and sterile for each person. The methodology of the fence guarantees the absence of the risk of infection. How is the PCR Test for Coronavirus, Covid? For the study, a smear from the oral cavity is taken: from the surface of the tonsils, the posterior surface of the pharynx, palatine arches.

• The nasal cavity - the tool is introduced to the required depth to the lower nasal sink, is carried out outside along the surface of the nasal passage. Then it is lowered a little down, inserted from the bottom into the nasal passage and, following the outside the wall of the nasal passage, the tool is removed with movements in the form of rotations.
• Then the tool is placed in a sterile test tube and sent to the laboratory.
• If the study is carried out from the vestibule of the nose, then the result of the test may not identify coronavirus SARS-COV-2.

Even in the absence of symptoms, the infection is easily detected in saliva and mucous tissues of the oral and nasal cavity, from the first days of infection. If there is a contact with the sick and the symptoms have appeared, then a smear is taken to determine there is a viral infection or antigenic composition of coronavirus in the body. It is necessary to make a PCR test no later than two weeks from the start of infection. After 7 days. From the onset of the disease, antibodies appear in the body. First formed immunoglobulin m, and two weeks later appears in the body immunoglobulin g. Therefore, the PCR test is made along with the test on immunoglobulin m if less than seven days have passed since the infection. A repeated test (two weeks later) is carried out with the dough for immunoglobulin G, to clarify the patient with coronavirus or not.

If there is confidence in contact with the patient, there are minor symptoms of a cold, it is necessary to visit a doctor, after examination, he will give a referral for analysis. With pronounced symptoms of colds and high temperatures, the doctor is called to the house, he will examine, clarify the symptoms and condition, and conduct the PCR test.

If the condition is severe, strong cough, shortness of breath, temperature rises above 38.5 ° CIn this case, they call an ambulance. She solves the issue of hospitalization or finding a house with a call of a local doctor. PCR test is carried out.

Attention:After passing the PCR test and before receiving effectiveness, it is necessary to be at home on self-isolation.

What can and what can not be done before the PCR test for coronavirus: how to prepare for the delivery of the analysis for Covid, the rules

As when passing any analysis, there are certain norms, so the PCR test requires compliance with the rules of delivery in order to avoid an error of inaccuracy. What can and what can not be done in front of PCR cords for coronavirus? How to prepare for the delivery of the analysis for Covid? The rules are described below. Immediately before the test is prohibited:

• Eat
• Smoke
• Drink drinks with alcohol
• Use chewing gum
• Take medications

When passing the analysis, it is important to observe individual protection measures. Be sure to put on the mask, use disposable medical gloves.

Remember: If the mask is disposable, then it requires replacement in two hours. The reusable also often needs to be changed and washed in a timely manner.

The PCR test for coronavirus gives out on an empty stomach - on an empty stomach or not: how is the analysis correctly.

Above the rules for passing the analysis were described. We repeat one of the most important. The PCR test for coronavirus is given on an empty stomach - on an empty stomach. How is the analysis correctly?

• To avoid a false result, food should be taken in 3-4 hours Before the analysis.

For the PCR test, it is important that the smear contains the required amount of infected cells. Eating cleans them from the mucous membrane of the oral cavity, and the accepted liquid rinses the infected cells.

Is it possible to drink alcohol before passing the PCR test and how will this affect the result?

The composition of antiseptics includes alcohol so that they have an active disinfectant effect, its percentage of content should be 60-80%. The composition of wines, vodka, etc. It includes much less. But its antiseptic properties can be enough to reduce the reliability of the result, and possibly the probability of coronavirus detection.

It follows that before passing pCR test, it is worth refrain from taking alcohol, even in minor doses, otherwise it will greatly affect performance, it will be inaccurate or false-negative. It is recommended not to take alcohol for two days before the smear is taken.

Why can't you brush your teeth before passing the PCR test?

Toothpaste may contain antiseptics. Even a slight hit in the test tube can distort the effectiveness of the analysis. Rinse of the oral cavity during teeth can also lower the content of cells affected by coronavirus. But the main goal of the smear in the PCR test is to obtain a sufficient number of biologist. material. Therefore, it is better not to brush the teeth before passing the PCR test.

The use of cosmetics (lipsticks, shine and lip balms) can affect the test result?

Since the test is taken from nos- and oropharynx, with the proper capture of biomaterial, the tool will not touch the lips and cosmetics will not hurt. But a random error can lead to a particle of cosmetics in the test tube and slow down the PCR reaction. It is better to use cosmetic products (lipstick, splendor and lip balmes) after the procedure so that this does not affect the effectiveness of testing.

Is it possible to use drugs in the nose and throat (drops, sprays, antiseptics) before passing strokes?

Medicines for the nose and throat (drops, sprays, antiseptics) destroy the virus. Accepting them in front of the PCR test, the surrender of strokes, you run the risk of getting the wrong result. The drugs are designed to relieve the inflammatory process, disinfect the nasopharynx and pharynx. When taking drugs, the number of the virus is reduced, you can get a false negative result, so it is better not to use them before the analysis.

Validity of the PCR test for Covid

The validity period has been reduced in Russia PCR teston Covid. At this time, it is 48 hours from the moment of receiving a laboratory result. This measure was adopted with the advent of a new strain. Now citizens who fly to the Russian Federation from other countries need to undergo testing twice and stay on self -isolation 14 days.

• The first test should be handed over no later than the second day of arrival, repeated surrenders on the twelfth day.
• The restriction of the air traffic is currently accepted with ten African countries.
• Reduction in validity PCR test It is explained by a high level of infection and the rapid spread of the virus.
• The new coronavirus strain is recorded in a number of countries, there are already infected in Russia.

In doubt caused by a state of health or suspicion of contact with an infected person, to protect yourself, your loved ones, hand over PCR test. It will help identify the virus at an early stage and start treatment faster. The disease from coronavirus can be life -threatening with its complications. In some cases, the body is very difficult to fight it, the mortality rate is quite high. Be healthy, and if necessary, make a PCR test.
