The staining test (MBD) is a reliable and sensitive method for the diagnosis of toxoplasmosis, which is positive in early infection and can last for 1 year, but the test requires live toxoplasmosis, which is difficult for general medical laboratory. . The positive reaction of complement fixation test appeared in the late stage of the disease and turned faster, and it has reference value in combination with the dyeing test.

Basic Information

Specialist classification: Infectious disease examination and classification: immunological examination

Applicable gender: whether men and women apply fasting: not fasting

Analysis results:

Below normal:

Normal value:

Above normal:


Prompt for the presence of Toxoplasma infection.

Tips: Properly handle the feces of domestic animals, domestic pets (especially cats), prevent contamination of food water sources, and wash your hands carefully after touching animal waste. Normal value

Negative colorless spots.

Clinical significance

The choice of antigen will directly affect the specificity and sensitivity of the assay. The general sensitivity is 92.3% and the specificity is 99.4%. It can be used for the diagnosis and epidemiological investigation of Toxoplasma infection.

Need to check the population of people with chorioretinitis, and water, microcephaly, brain calcification and other symptoms, pregnant women with toxoplasmosis, the baby is best to check whether there is a disease.


Because the method requires live toxoplasma, it is difficult to carry out clinical laboratory development.

Inspection process

The method of detection: using Toxoplasma gondii tachyzoite soluble antigen and colloidal gold labeled SPA, according to the principle of immunodiafiltration, a point immunogold diafiltration assay for detecting IgG antibodies against Toxoplasma gondii was established.

Not suitable for the crowd

There are no taboos.

Adverse reactions and risks

There are no related complications and hazards.
