The number of people infected with coronavirus is increasing in the world. Information about deaths and the number of recovered is constantly emerging. Those who have recovered are interested in what antibodies should be for coronavirus after an illness.

What antibodies are required for

Antibodies indicate resistance and resistance to foreign cells. If the analysis shows their presence for a specific disease, this means that the patient has had it or received a vaccination. Antibodies to coronavirus show that a person has recovered or is now suffering from an infection.

Upon contact with foreign microorganisms, the immune system secretes immunoglobulins - these are antibodies. They are present in the blood, react to the penetration of viruses.

The activity of the reaction is associated with the characteristics of the organism. Asymptomatic coronavirus indicates a weakened immune system. With an active struggle, a person's temperature rises, all the painful symptoms of infection are revealed.

When there are many antibodies, this indicates resistance - the body is fighting the infection.

To determine antibodies, an analysis is performed by taking blood from a vein. The result appears within 1-3 days.

When to take an antibody test

The coronavirus has the following stages:

1. Incubation. There are practically no symptoms of the disease, but the person is considered a carrier. May be up to 2 weeks.
2. Initial. Lasts 5-7 days. Symptoms are mild.
3. Active. There is an increase in temperature, the appearance of cough, shortness of breath, weakness. The sense of taste and smell also disappear. Observed for 1-2 weeks.
4. Final. Symptoms are lessened and improvement is felt. May last 3 weeks.
5. Recovery. Lasts 2 weeks - a month. Lasts until you recover.

At each stage, different antibodies are produced. Therefore, there are tests that take this feature into account.

The production of IgM protein occurs when an intense fight against the virus is required. The protein is present in the blood for about 7 days, and is formed on the 5th day of infection. The highest concentration is observed 10-14 days after recovery.

IgM antibodies indicate the initial and active stage of infection. The IgG protein appears in people who have had coronavirus.

Where tests are done

In every city of Russia, diagnostics for antibodies to infection is carried out. Testing is carried out free of charge in polyclinics with registration and for a fee in private clinics.

You can contact the laboratories "Gemotest" and "Invitro", which function in many cities.

Number of antibodies

The indicator 1, 1 of the IgG protein indicates the presence of immunity to the ailment that was transferred. IgA and IgM antibodies should not be, since the body does not need to fight the virus.

Those who have been ill are interested in what antibodies should be for coronavirus after an illness. A positive IgM indicates an active infection. And positive IgA numbers confirm the initial stage. An IgG parameter of 40 indicates the fact that you have had Covid-19.

After recovery, people can become donors. It is necessary to donate blood, which will be used to excrete plasma. The drug is used to improve well-being in severe cases.

Donors need to follow these rules:

1. It is forbidden to drink alcohol for 2 days.
2. At the same time, you should not eat fatty, high-calorie foods.
3. You should not go to the procedure on an empty stomach.

Donors should have an IgM of 1, 5 or more, and an IgG above 40. Only then can a person donate blood.

Not everyone knows how many antibodies should be due to vaccination. After vaccination, the formation of immunity occurs within 21 days. The IgG value should be elevated, but it is different for each person. How many antibodies there should be to protect against relapse, doctors have not yet figured out.

Antibody testing helps to determine whether a person has had an infection, whether he is in the active phase of infection.

Outcome

1. After recovery, the person should develop antibodies that protect against infection.
2. This is established through testing.
3. Antibodies are also produced through vaccination.
