The full name of this blood test — ELISA (enzyme-linked immunosorbent assay). This laboratory method can accurately determine the presence and amount of different compounds, macromolecules, viruses, etc. the analysis is based on the specific reaction of the organism to the antigen-antibody.

The advantages of the above techniques of determining the windmill visible to the naked eye:

  • conveniently;

    As the analysis determines a windmill?

    Анализ на антитела к ветрянке: где сдать и как расшифровываетсяSpecific antibodies to the virus Varicella-Zoster appear in the human body after 4-5 days after the onset of the rash. This process is called seroconversion. Seroconversion is the appearance of IgG specific antibodies in their initial absence.

    Other antibody — IgM confirm the presence of disease. After recovery of IgG retained in the human body for life and indicate immunity to smallpox.

    The virus Varicella-Zoster have been ill can no longer be activated and provoke smallpox, however, can develop into shingles. These complications occur in people with weak immune systems from nature.

    In the blood of the newborn in the first months of life may be present IgG even if he is not ill. Antibodies are passed from mother to him.

    Where to hand over IFA? How much is it?

    Анализ на антитела к ветрянке: где сдать и как расшифровываетсяWhere to donate blood for the detection of antibodies to chickenpox? Today, there are 2 reputable laboratories, which conducted similar studies.

    This lab Invitro and Hemotest. These institutions are equipped with high-precision modern equipment and offer diverse services at affordable prices.

    For example, the price of the ELISA in Invitro equates to 700-800 rubles, and in Gemotest — 750-850 RUB.

    To give blood you need to prepare

    If you don’t want to get inaccurate results and to retest the blood again, I recommend to properly prepare for the procedure. For this you need to observe the following rules:

    • you can donate blood only after 8 hours after ingestion (preferably on an empty stomach in the morning);
    • before the procedure can’t drink medications;
    • if treatment has already begun, must be in the lab what drugs were taken;

    Interpreting the results of ELISA

    Анализ на антитела к ветрянке: где сдать и как расшифровываетсяInterpreting the results of the analysis on antibodies to chickenpox — a complex process that requires certain knowledge. The results are recorded in a special form regulation and indicators.

    If to explain in simple language, decoding can be described as follows: if the number of antibodies is less than normal, the result is negative, if more, positive.

    If you want to better understand the ELISA, here’s the possible list of results:

  • If lgM antibody positive (above normal), and IgG negative, the disease is in the initial period and is acute.
  • If IgG positive and lgM, the disease is considered acute, primary, abiding in the late period or deaktivirovana (can start shingles).
  • If IgG and lgM negative, the person is healthy and chickenpox he’s never had.
  • If IgG positive and lgM negative, then the person has immunity to the virus, as it they had been ill or he produced a vaccination for prevention.
  • Agree, if you look, it’s not so difficult as it seemed initially. Now let’s take a closer look at the case where the IFA is assigned when planning a pregnancy.
