Are there tests for coronavirus in Tver

Today, the most popular is the analysis for covid-19. In Tver, such a study is carried out in citizens with symptoms of the disease or in those who have recently returned from abroad. According to the government, there are enough tests in the region to detect coronavirus infection.

How is coronavirus diagnosed?

This diagnosis can only be confirmed by laboratory testing. For this, RT-PCR (reverse transcription polymer chain reaction) and ELISA (enzymatic immunoassay) are used. Using enzyme immunoassay, antibodies are detected and titers of specific antibodies are determined.

Important! If pneumonia is suspected, the doctor will order an x-ray.

The first test, reverse transcription polymer chain reaction, is carried out only in specially equipped laboratories. To do this, a swab is taken from a person’s throat or nose, and, after the studies, the presence or absence of the virus is established.

The second test is enzyme-linked immunosorbent assay, or, a rapid test, indicates the presence or absence of immunoglobulins in the blood. Its efficiency is lower than that of the first one, because. indicates only indirect signs of the presence of the disease. Usually immunoglobulins, antibodies, are produced a week after infection.

Not every person can pass this test, it is usually carried out if there are severe symptoms of covid-19, or if there is information about contact with an infected person. To begin with, the doctor makes sure that the patient does not have the flu, for this they make a swab from the nose. After that, the possibility of the presence of other viruses, for example, adenoviruses or rhinusitis, is excluded. If all diagnoses are refuted, then the collected biomaterial is sent to the laboratory to be tested for the presence of coronavirus infection.

Important! You should not buy express tests for self-diagnosis of the disease, this requires medical knowledge. It is worth noting that such tests do not give a 100% result.

What biomaterial is needed

To detect the virus by RT-PCR, the following samples are taken:

1. From the lower respiratory tract:
2. sputum;
3. aspirate;
4. lavage.

2. From the upper respiratory tract:

• nasopharyngeal and oropharyngeal swabs;
• nasopharyngeal flush.

With the “Serology” research method, serum is taken for serological testing. Paired specimens should be tested to confirm the diagnosis, i.e.:

1. In the first week after the onset of symptoms, the first sample is taken.
2. If possible, the second is taken after 2-3 weeks.

Important! If the above deadlines cannot be met, then sampling is carried out no earlier than two weeks after the onset of symptoms.

If the disease is asymptomatic, but there was contact with the infected, nasopharyngeal and oropharyngeal swabs are taken for PCR analysis, if possible, then sputum. For analysis "Serology" - serum. It is necessary to conduct a laboratory study within two weeks from the moment of contact with an infected person.

When conducting a laboratory study "Serology", after 2-3 weeks, a repeated analysis of the serum is taken.

How long to wait for the result

You won’t have to wait long for the result of a coronavirus test in Tver, usually they are ready in 4-6 hours. However, there are times when the result will have to wait a bit, for example, if the laboratory is far away. In this case, test tubes with biomaterials are transported at a temperature not exceeding 4 degrees Celsius.

Important! If it takes more than 3 days to transport the biomaterial, it is recommended to keep it at a temperature of -80 degrees and transport it in dry ice.

How many times the test is repeated

The examination is repeated at least two times. Testing for coronavirus in Tver to clarify the diagnosis in people who do not have symptoms is carried out from the respiratory tract until two consecutive negative tests are obtained. How often the analysis will be performed depends on the specific circumstances of the disease.

Important! They should be selected at least once every 2-4 days.

If the result is necessary to transfer the patient from the isolation room, then it can be done every day.

To detect antibodies and confirm the presence of infection, paired samples are needed, which are taken after a certain period of time. If possible, this interval should be from 14 to 21 days.

Important! The first sample is taken during the first week of illness.

If a single serum sample is used, it should be taken no earlier than two weeks after the onset of symptoms.

Is there a coronavirus system test in the city

Tver and the region are provided with sufficient tests for coronavirus. The selected samples are sent to the Center for Hygiene and Epidemiology of the Tver Region, where samples are examined.

If the test results are positive or doubtful, the samples are sent to the Vector State Scientific Center for Virology and Biotechnology, which is located in the Novosibirsk Region.

Symptoms to check: who can count on a free test

Any person cannot be tested for coronavirus in Tver, this is done in two cases:

1. In the presence of symptoms of the disease (dry cough, fever).
2. They came into contact with a person who later tested positive for coronavirus.

In the first case, the symptom appears within two weeks of visiting countries with an "adverse epidemiological situation". Upon returning from there, a person must voluntarily go into self-isolation and pass all the necessary tests. Only after at least two weeks have passed, if the test results are negative, you can return to your usual lifestyle.

Where to go to get tested for coronavirus

If you have returned from abroad or feel symptoms of a coronavirus infection, you should immediately seek medical help. It is best to do the following:

1. Call a doctor at home or go to the nearest medical facility on your own.
2. Inform the doctor about visiting "countries with an unfavorable epidemiological situation."
3. After that, the doctor will send you for a coronavirus test. For this, a swab is taken from the nose and throat.

Important! Be sure to report contact with people. They also conduct tests for coronavirus infection.

4. The doctor hospitalizes the patient in the infectious diseases department of the hospital, after which a number of laboratory tests are also carried out.

5. From the clinic, the analysis is sent to the nearest medical center of Rospotrebnadzor. There are such centers in every region of Russia.

6. After 4-5 hours, the test result will be ready. If he does not confirm the presence of infection, another swab is taken. And after receiving two negative tests, the patient is transferred to a general hospital.

Many people want to take such a test without having symptoms of the disease, but there are fears of infection. In this case, it will be much more difficult to do this. You can contact private centers where a doctor's referral is not required, however, such tests are paid for this. In any case, if you have symptoms of SARS, you can contact the local clinic, where the doctor, based on the history, will give further instructions.

Private laboratories: prices, addresses, phones

At the moment, you can take tests for coronavirus without a doctor's referral only in two medical centers:

1. "Helix" - centers are located in St. Petersburg, Moscow and Yekaterinburg.
2. "Gemotest" - medical centers are located in Moscow, Dzerzhinsky, Podolsk, Mytishchi, Krasnogorsk, Balashikha and Odintsovo. Work in Simferopol should begin in the near future.

Preliminary cost of analysis:

• Petersburg - 200 rubles;
• Moscow and the region - 300 rubles;
• Yekaterinburg - 180 rubles.

Important! In the near future, the Invitro Medical Center plans to start testing for coronavirus infection.
