Assessing Toxoplasmosis Status: Why it is Included in Our Antenatal Panel
Discover why toxoplasmosis screening is a key part of our antenatal blood panel. Learn what the test measures, who should consider it, and what results may indicate.
Toxoplasmosis screening during pregnancy is one of the most clinically informative additions to a comprehensive antenatal blood panel. Understanding your toxoplasmosis status before or during early pregnancy can provide valuable information to support informed decision-making and appropriate medical follow-up. At Health Screening Clinic, this test forms part of our extended antenatal screening service — if you are arranging tests early, see how to arrange a private antenatal health assessment appointment.
What Is Toxoplasmosis? A Clear Definition for Expectant Mothers
Toxoplasmosis is an infection caused by the parasite Toxoplasma gondii, commonly acquired through contact with cat faeces, raw or undercooked meat, or contaminated soil and water. In healthy, non-pregnant adults, it often produces mild or no symptoms. However, during pregnancy, understanding immune status to this parasite carries particular clinical relevance.
How Is Toxoplasmosis Detected? Understanding the Serology
Toxoplasmosis status is assessed through a blood test that measures two types of antibodies:
| Antibody | What It May Indicate | Clinical Relevance |
|---|---|---|
| IgG | Previous exposure and likely immunity | May suggest past infection with developed immunity |
| IgM | Possible recent or active infection | May warrant further clinical evaluation |
| Both negative | No prior exposure detected | May suggest absence of immunity |
| IgG positive / IgM negative | Established immunity | Generally considered lower risk in pregnancy context |
| IgM positive | Possible recent infection | Referral to appropriate healthcare provider recommended |
The presence and pattern of these antibodies help inform the overall clinical picture. Results are reported for educational awareness and should always be reviewed in context with a qualified healthcare professional.
Practical Insight: A positive IgG result alone is often reassuring, as it may suggest established immunity. However, interpretation should always involve appropriate medical guidance, particularly when results are ambiguous or when IgM is detected.
Why Is Toxoplasmosis Included in Our Antenatal Panel?
Many women attending private antenatal screening clinics across London and the UK are surprised to learn that toxoplasmosis is not routinely included in NHS antenatal blood panels in England. While NHS guidance acknowledges the infection’s significance, routine universal screening is not currently offered in England (unlike France, where it is mandated by law).
This is precisely why our private antenatal health assessment approach includes this marker — to offer a more complete serological profile for those who want proactive information about their immunity status before or during pregnancy.
Understanding your toxoplasmosis serology status gives you and your healthcare provider a baseline for decision-making, lifestyle awareness, and appropriate referral if needed.
Who Should Consider Toxoplasmosis Testing During Pregnancy?
You may particularly benefit from testing if you:
- Are pregnant or planning a pregnancy and have no previous test results
- Own cats or regularly handle cat litter
- Frequently handle raw or undercooked meat during food preparation
- Work in gardening, farming, or outdoor environments with soil exposure
- Have travelled internationally and may have consumed undercooked meat or unpasteurised products
- Have a weakened immune system or a history of immunosuppressive conditions
- Simply want a comprehensive antenatal health baseline as part of your pregnancy planning
Testing is suitable for those at any stage of early pregnancy planning or in the first trimester, though it can be requested at any point. Our nurse-led team is experienced in advising on appropriate timing for antenatal blood panels.
Practical Insight: Testing in the pre-conception period or early first trimester is often most informative, as it allows the clearest baseline assessment of immune status before any potential exposure-related changes may occur.
How Often Should Toxoplasmosis Status Be Assessed?
Toxoplasmosis immunity status does not typically require repeated annual testing in the general population. However, in the context of pregnancy:
- Prior to pregnancy: A single test may establish baseline immune status
- During the first trimester: Testing may confirm current serological profile
- If a previous result showed IgM positivity: Follow-up testing at a 2–3 week interval may be recommended by a healthcare provider to assess antibody avidity and clarify timing of infection
- In subsequent pregnancies: If results from a previous pregnancy are available and IgG was confirmed positive, retesting may not always be necessary — though this should be discussed with an appropriate healthcare professional
Our clinic offers antenatal screening packages that include toxoplasmosis testing alongside other key markers relevant to pregnancy health; for context on wider immune-marker planning, see early immunity assessments for infant health.
What Your Toxoplasmosis Test Results May Mean
Receiving your results can feel uncertain without context. Below is a general educational guide to interpreting common result patterns:
- IgG Positive, IgM Negative: May suggest previous infection and developed immunity. This is a common and generally reassuring result pattern in adults.
- IgG Negative, IgM Negative: May indicate no prior exposure. This can suggest you have not yet been infected and may benefit from preventive hygiene guidance.
- IgM Positive (with or without IgG): May indicate recent infection or reactivation. This result warrants prompt referral to an appropriate healthcare provider for further evaluation.
- Borderline or equivocal results: May require repeat testing or avidity assays to clarify the timeline of infection.
All results from Health Screening Clinic are provided in a written report format. Our nurse-led team will advise on when onward referral to appropriate healthcare services is recommended.
Practical Insight: Results should never be self-interpreted in isolation. Please ensure all results are shared with your midwife, GP, or appropriate antenatal care provider for clinical context and guidance.
NHS vs Private Toxoplasmosis Testing: Understanding Your Options
| Factor | NHS Antenatal Pathway (England) | Private Antenatal Screening (Health Screening Clinic) |
|---|---|---|
| Routine toxoplasmosis screen offered | Not routinely offered in England | Included in our antenatal blood panel |
| Speed of results | Variable | Typically fast turnaround |
| Flexibility of timing | Aligned to NHS schedule | Flexible appointment booking |
| IgG and IgM both reported | Not standard | Both antibody markers assessed |
| Nurse-led reporting | Varies | Nurse-led clinic with written report |
This comparison is intended to be informative and neutral. NHS antenatal care remains an essential service for all pregnant women in the UK. Private screening serves as a complementary option for those who want expanded serological information.

Frequently Asked Questions: Toxoplasmosis Antenatal Testing
1. What is toxoplasmosis screening in pregnancy?
Toxoplasmosis screening in pregnancy involves a blood test that measures IgG and IgM antibodies to Toxoplasma gondii. The results may indicate prior immunity, recent exposure, or the absence of previous infection, helping inform appropriate antenatal follow-up and lifestyle guidance.
2. Is toxoplasmosis testing offered on the NHS during pregnancy in England?
Routine toxoplasmosis screening is not currently included in the standard NHS antenatal blood panel in England. Private antenatal screening, such as that offered at Health Screening Clinic, can include this marker for those who want a more comprehensive serological profile.
3. What does a positive IgG result for toxoplasmosis mean?
A positive IgG result may suggest previous exposure to Toxoplasma gondii and the development of antibodies. In the absence of a positive IgM result, this is often considered reassuring and may suggest established immunity. Results should always be reviewed with an appropriate healthcare professional.
4. Is toxoplasmosis dangerous during pregnancy?
Primary infection acquired during pregnancy — particularly in the first and early second trimester — may carry clinical significance. However, the majority of adults with prior immunity are not considered at elevated risk of new infection. Your healthcare provider is best placed to interpret your individual result in context.
5. How is the toxoplasmosis blood test carried out?
The test involves a standard venous blood draw, typically from the arm. At Health Screening Clinic, this is performed by a qualified nurse, and samples are sent to an accredited UK laboratory. Results are returned in a written report.
6. Can I have this test if I am not yet pregnant?
Yes. Pre-conception testing is a common and clinically logical time to assess toxoplasmosis immunity status, as it provides a clear baseline before pregnancy begins. For another pre-conception immunity marker, see varicella immunity screening before pregnancy.
7. What happens if my IgM result is positive?
A positive IgM result may indicate recent or active infection and warrants prompt review by an appropriate healthcare provider or specialist antenatal service. Our clinic will advise on onward referral at the time of result reporting.
8. Does Health Screening Clinic offer treatment for toxoplasmosis?
No. Health Screening Clinic is a nurse-led testing and screening service. We do not prescribe medication, offer treatment, or provide GP services. If a result indicates the need for further clinical management, we will advise appropriate referral to suitable healthcare services.
9. How long does it take to receive toxoplasmosis test results?
Results are typically available within a few working days of your blood draw, depending on laboratory processing times. Our team will confirm expected turnaround times at the time of your appointment.
10. How does toxoplasmosis testing fit into a broader antenatal health check?
Toxoplasmosis testing is one of several serological markers included in our extended antenatal blood panel.
