Testing for toxoplasmosis


Testing for toxoplasmosis is a blood test with the aid of which the antibodies were tested to parasite Toxoplasma (Toxoplasma gondii). Upon infection with this parasite body's immune system produces antibodies. Titer and type of these antibodies can indicate whether the infection is old or new. Within several weeks, may be required to make a number of tests.
For most people with Toxoplasmosis infection is not dangerous. Of infection in pregnant women is dangerous because it is transmitted to the baby, it can cause brain damage and vision.
May acquire toxoplasmosis in eating poorly cooked or raw meat of an animal that is infected or if you have contact with droppings. Once the catch in the body to form antibodies to the parasite Toxoplasma gondii. These antibodies remain for life and protection from reinfection.
To investigate whether the fruit is infected can be made amniocentesis - sampling of the amniotic fluid.
In which case it is recommended that research?
Testing for toxoplasmosis is conducted in the following situations:
In pregnant women - to explore the type and antibody titer. If a pregnant woman has a titer of IgG antibodies, that means that the infection is old and has no risk of infection to the baby. If the titer of IgM antibodies is, this means that the infection is completely new and has a risk of infection to the baby.
In toxoplasmosis baby.
In people with diseases that affect the immune system - such as AIDS.
Do I need prior training?
Prior to conducting the assay testing for toxoplasmosis is not needed particular preparation.
Tell your doctor if:
Are pregnant and have contact with cats or clean the feces of cats report it to your doctor.
Have bleeding problems or taking IN SITU PLATE medicines that reduce blood clotting.
A method of conducting the survey:
Collection of blood by a medical professional:
Place the elastic cuff of the arm, with the aid of which the veins become larger and easier collection of blood;
Clean the place where the blood will be taken;
Insert the needle into the vein. It is possible to have more than one attempt for sampling blood
Place the syringe;
Syringe is filled with blood;
After collection of a sufficient quantity of blood sample was removed elastomeric membrane;
Place the cotton ball over the needle, and then she carefully pulled from the vein;
Pressed to the place from which blood was taken THE MICRORT SYSTEM.
What do you feel during the test?
Blood sample for testing for toxoplasmosis is taken from a vein in the arm. In this study, you can feel the tightening of the elastic cuff. At the time of blood sampling will not feel anything except possibly a slight stinging when inserting the needle.
Are there risks of conducting research?
When taking venous blood for testing for toxoplasmosis, there is minimal risk of some problems:
The place where the blood was taken can occur bruising. To reduce the risk of this complication is usually sufficient squeezing site for several minutes after withdrawing the needle.
Very rarely can occur inflammation of the vein. This condition is called phlebitis and usually resolves after treatment with bandages.
In people with bleeding problems may have prolonged bleeding. Prolonged bleeding may also have at the intake of some drugs, such as aspirin, warfarin, etc. That prevent the blood from clotting. If you have any bleeding problems or are taking medication tell your doctor.
Results from the survey:
Testing for toxoplasmosis is a blood test with the aid of which the antibodies were tested to parasite Toxoplasma (Toxoplasma gondii). Upon infection with this parasite body's immune system produces antibodies. Titer and type of these antibodies can indicate whether the infection is old or new. The higher was the level, the more antibody has the blood.
The survey results are ready within 1 to 3 days.
Normal values:
IgM in infants: invisible
IgM in adults less than 1:64
IgG: less than 1:1024
Deviations from the norm:
Antibodies after infection with Toxoplasma formed after 2 weeks. Titre is the highest of the first to second month after infection.
If found high levels of IgM antibodies of this type means that the infection is new. High antibody titer of IgG type means that the infection is old and has occurred in the past.
Within a few weeks, can be made a few blood tests to determine whether increases in antibody titer. This means that the infection is new.
Low titers, which increased talk of an old infection. Once infected with toxoplasmosis can not be infected again CRYO SHUTTER.
When you should do research?
Testing for toxoplasmosis can not be held or why the results may not be helpful in the following cases:
The presence of an infection in newborns can cause a false positive result.
The presence of other antibodies, such as rheumatoid factor, antinuclear antibodies, can also be a cause of a false positive result.
