An adult and healthy person may not even notice the appearance of toxoplasma in his body - infection with an infection and the disease itself, in most cases, is asymptomatic, without causing significant inconvenience and without reducing the quality of life. However, during pregnancy, an analysis for toxoplasmosis is mandatory: it is recommended to do it both before the planned conception and during the bearing of the child.

Why do I need to be tested?

Toxoplasmosis is the presence in the human body of parasitic cells that penetrate the internal organs and live off the fact that they receive nutrients from them. For an adult, this infection does not pose a great danger, but for expectant mothers, the ingestion of Toxoplasma is a threat to the health of their unborn child - a congenital infection significantly increases the risk for the manifestation of life-threatening diseases such as jaundice, hydrocephaly and microcephaly.

Also, finding this infection in a child's body threatens with the manifestation of epilepsy and brain abscess. The expectant mother must definitely check her body so as not to pass on parasites to the child, which will pose a much greater threat to him than to an adult and strong body.

Important! The main and final carrier of Toxoplasma parasites is domestic cats. He can live in other organisms, but reproduce - only in these pets living in many homes

Types of tests for toxoplasmosis

In laboratory studies, several options for detecting toxoplasmosis are used. The use of various methods allows you to get a reliable result - each of these studies has a narrow profile, and on the basis of all the collected indicators, an integral picture of the behavior of the infection in the human body is built (in the event that the analyzes show its presence).



The indirect immunofluorescence reaction detects the presence of toxoplasma in the blood at an early stage. The study is carried out by observing the reaction of serum with antibodies and human biological material.


The enzyme-linked immunosorbent assay occupies a leading position among all tests for toxoplasmosis - it allows you to obtain comprehensive information about the infection contained in the body. For the study, various biological materials are used - blood, cerebrospinal fluid, amniotic fluid. ELISA allows you to determine the presence or absence of toxoplasma in the body, as well as its amount (with a positive result).



PCR analysis (polymerase reaction method) is a popular method for examining the body for toxoplasomosis - it is often asked for a detailed and reliable result. During the analysis, the DNA of parasitic Toxoplasma organisms is searched for in human blood.


The complement binding reaction (a system of complex proteins present in human blood) shows the interaction of antibodies with biological material - this reaction allows you to determine the presence of parasites in the body.


A timely detected infection in the expectant mother will help prevent diseases in her child - therefore, it is very important to diagnose the body. Below is detailed information on toxoplasmosis tests that are required during pregnancy.


How to get tested for toxoplasmosis?

The process of passing the analysis of a pregnant woman for toxoplasmosis differs depending on what specific biological material is proposed for research. The following is checked for infection:

  • blood;
  • urine;
  • saliva;
  • sputum;
  • amniotic fluid.

This analysis does not require special preparation before passing: regardless of the type of study, the requirements are identical to any other study of blood and other biological materials.

In order to get a reliable result and have a clear idea of ​​the state of your own body, you must adhere to several rules:

  1. Exclude the use of antibiotics 14 days before the day of the test. For some pregnant women, these drugs are necessary and prescribed by a doctor, but their blood levels distort the test results, so you will need to take a break for a period of two weeks.
  2. 3-4 days before the test, fatty and spicy foods, spices, strong tea and coffee should be excluded from the diet. Alcohol is also prohibited (its use is highly discouraged during the entire period of pregnancy).
  3. On the day of the test, you need to give up perfumes with a strong aroma.
  4. The research results can only be correctly interpreted by a professional doctor. It is strictly not recommended to draw conclusions and take measures on your own - any actions must be agreed with the doctor who coordinates the expectant mother for the entire period of pregnancy.

When to get tested for toxoplasmosis during pregnancy

An analysis for toxoplasmosis is mandatory during pregnancy - timely detected and eliminated infection will exclude the possibility of a child with congenital diseases (jaundice, hydrocephalus, microcephalus).


Materials are sent for research several times: when planning a pregnancy and several times during routine examinations. The exact number of tests is consistent with the recommendations of the supervising physician (they may differ depending on the success of the treatment process, the presence of this infection in the blood before, and the individual reaction of the body).

In some cases, the test for toxoplasmosis should be taken unplanned - if the patient begins to show symptoms that indicate infection. These include:

  • a sharp increase in body temperature up to 38 degrees;
  • fever, chills;
  • decreased appetite, memory impairment;
  • muscle and headaches;
  • swollen lymph nodes;
  • the acquisition of a yellowish skin tone;
  • the manifestation of rash and redness on the skin;
  • manifestation of nervousness, stress, apathy.

Decoding a blood test

The results of a study for toxoplasmosis must be read and deciphered by a doctor, after which he gives recommendations for improving the body (in case the indicators are not normal). It is categorically not recommended to draw conclusions and start treatment on your own.


However, it will be helpful for a pregnant woman who is concerned about her health to know what the marks on the lab sheet mean. This will help to responsibly approach the study of your body and rely not only on the words of the doctor, but also on your own knowledge.

The indicators of the analysis for toxoplasmosis have the following designations:

  • IgG, IgM- (there is no infectious agent in the blood, but the immune defense is almost completely absent - its increase and constant research of the body in each trimester are required);
  • IgG +, IgM- (the body is well protected by immunity from toxoplasma);
  • IgG-, IgM + (the body has a strong reaction to Toxoplasma parasites, a high risk of infection of the child);
  • IgG-, IgM- (high risk of primary infection, PCR analysis is required).

What is Toxoplasma avidity

Avidity to Toxoplasma is one of the indicators on the basis of which conclusions are drawn about the presence of infection in the body. It is called the ability of antibodies to bind to parasitic cells and fight it.


What is IgG positive

When decoding the analysis for toxoplasmosis, the IgG indicator is the presence of antibodies in the blood. A positive result means an activation of the infection - latent or chronic (> = 3), a negative result indicates the absence of infection (<1). The measurement takes place in "IU / ml" - the amount of antibodies per milliliter of blood.

What indicators are normal

The most commonly used test for toxoplasmosis, PCR, shows the test results as an avidity indicator
