TOXO IgM & IgG Test Kits

Both one-step lateral flow Rapid Test kit and Dot Filtration Assay kit are available for the detection of toxoplasma IgG and IgM antibody isotypes, which are used in diagnosis of toxoplasma infection.

Toxoplasma POCT Rapid Test

TOXO IgG & IgM Test Kits

For the detection of Toxoplasma infection, Atlas Link Technology Co, Ltd supplies both lateral flow Toxoplasma rapid test kits and Toxoplasma Dot Assay Kits; for both methods, both IgG and IgM test kits are available.

All these rapid TOXO test kits are based on the principle of Gold Immuno-chromatography Assay (GICA), using the antibody-antigen reaction to detect IgM and IgG antibody isotypes in human serum or plasma specimen respectively.

Application of TOXO Test

By detecting the Toxoplasma specific antibodies in serum samples from pregnant women, and by differentiating the IgM and IgG antibodies, TOXO test kits help to determine the immune status and the infection status of the patient, thus help administration properly.

Effects of Toxoplasma Infection

Toxoplasmosis is a systemic disease, caused by the protozoa Toxoplasma gondii. Human can be infected by contacting with infected meat and feces of a cat that has recently been infected, or by transmission from mother to fetus.

About one third of the world's human population is estimated to carry toxoplasma. During the first few weeks after infected, the infection typically causes a mild flu-like illness. Thereafter, the parasite rarely causes any symptom in adults. However, infection in a fetus can lead to serious consequences; abortion and stillbirth may occur when infection takes place during the first trimester of pregnancy, and irreversible neurological damages in case of infection during the second or third trimester.

Specimen

Serum Collection

Collect blood specimen into a red top blood collection tube by vein puncture, which contains no anticoagulants.

Allow the blood to clot, or separate the serum by centrifugation.

Carefully withdraw the serum into a new pre-labeled tube.

serum Storage Condition

Test specimens as soon as possible after collecting. The specimens can be stored up to 5 days at 2-8°C if not tested immediately. The specimens should be frozen at -20°C for longer time storage. Don’t freeze and thaw the specimens for many times. Prior to testing, bring frozen specimens to room temperature slowly and mix gently. Specimens containing visible particulate matter should be clarified by centrifugation before testing. Do not use samples demonstrating gross lipemia, gross hemolysis or turbidity in order to avoid interference on result interpretation.

Testing Principle of Lateral Flow Indirect

GICA Indirect Method Illustration

In the lateral flow indirect chromatographic rapid test, recombinant or purified antigens are immobilized in the test band region. In the end of the Conjugate pad of the membrane strip where the samples are supposed to be added, rabbit or mouse anti-human IgG antibodies conjugated with colloidal gold particles is embedded.

During the testing process, specimen is added to the end of the membrane strip. anti-IgG colloidal gold particles resolve into the specimen, where the anti-IgG conjugate will react and bound with the target IgG antibody, if present.

This complex of IgG and anti-IgG will move along the membrane strip to the testing band region, under capillary effect, where the immobilized antigen captures the IgG antibody. When the antigen-IgG-Anti-IgG complex accumulate on the test band region, the congregated colloidal gold particle will develop red or pink color, indicating there are target IgG antibodies in the specimen.

If there is no target IgG antibody in the specimen, the secondary anti-IgG conjugate will not bind to the immobilized antigen in the test band region, and no color will develop.

As a procedural quality control, a secondary antibody or recombinant antigen will be immobilized in the control band region. When the specimen climb to this region, the unbound anti-IgG colloidal gold particle will be captured, thus a red band will always develop. This inner control process ensure that enough specimen is added, proper testing procedure has been followed, and the reagent has not deteriorated.

Testing Principle of Lateral Flow Capture

GICA Capture Method Illustration

For the detection of IgM-class antibodies, in order to avoid the interference from the IgG class, capture assays technology is usually the best choice.

In capture lateral flow test kit, a secondary antibody, usually antibody directed to human IgM (anti-human IgM), is immobilized in the test band region on the strip membrane. And monoclonal viral antigen or protein conjugated with colloidal gold particle is embedded in the end of membrane strip.

During the testing process, the sample is added to the end of the membrane strip, the embedded antigen conjugate will resolve into the sample, where the target IgM antibody, if present, will react with and bound to the antigen conjugated with colloidal gold particles.

When the IgM-antigen complex moves to the test band region under the capillary effect, the IgM antibody will be captured by the immobilized anti-human IgM antibody. When the colloidal gold particles congregate in the test band region, a red or pink color will develop, indicating a positive result.

If there is no IgM antibody in the specimen, the antigen conjugated with colloidal gold particle can’t be captured by the anti-human IgM secondary antibody, and no color will develop, indicating a negative result.

Testing Principle of DGFIA Capture

DGFIA Capture Method Illustration

For the detection of IgM-class antibodies, capture technique has its advantage in that it can reduce the interference from the IgG class, thus increase the specificity of the test kit.

In a capture dot filtration test kit, antibodies directed to human IgM antibody (anti-i chain) are pre-coated in the test region on the millipore filtering membrane. When specimen is added, the IgM, if present, will be captured by this secondary antibody, anti-IgM.

After washing away the specimen, especially the IgG antibody, the antigen conjugated with colloidal gold particle will be added. If the IgM antibody was captured in the prior step, the IgM will bind to the antigen conjugate. When the colloidal gold particles congregate, a red or pink color will develop, indicating a positive result.

If no IgM in the specimen, this complex will not develop, the antigen conjugated colloidal gold particles will not congregate, and no color will develop in the test region, indicating a negative result.

Testing Principle of DGFIA indirect

DGFIA Indirect Method Illustration

With indirect Dot filtration test kit, the millipore filtering membrane is pre-coated with purified or recombinant viral antigens. The detecting conjugate reagent is stored in a vial, whose main component is rabbit anti human IgG (anti-IgG) antibodies, which is conjugated with colloidal gold particles.

During the first step, sample is added to the sample well in the test cassette. The target IgG antibodies, if present, will be captured by the pre-coated antigens.

The wells are washed to remove unbound serum proteins. Then, the colloidal gold conjugate is added. If the target IgG antibodies have been captured in the first step, the IgG antibody will react with the added secondary antibody, anti-IgG conjugate, and red color will develop, indicating a positive result.
