Supporting Maternal Wellbeing with Routine Infection Screening
Discover how routine infection screening during pregnancy supports maternal wellbeing. Learn which tests matter, when to screen, and how private testing in London can help.
Routine infection screening during pregnancy can be a proactive step expectant mothers take to support their own wellbeing and that of their developing baby. Many infections in pregnancy can be present without obvious symptoms, making timely blood testing a valuable part of any maternal health approach. Whether accessed through NHS pathways or private health screening services in London, understanding what these tests involve — and why they matter — can help women make informed, confident decisions throughout their pregnancy journey.
What Is Routine Infection Screening in Pregnancy?
Routine infection screening in pregnancy refers to a structured series of blood tests designed to identify infections that may affect maternal health or require clinical attention during or after pregnancy. These tests detect specific antibodies, antigens, or markers in the blood that can suggest the presence of certain infections — even in women who have no visible symptoms.
Definition (Snippet-Optimised): Routine infection screening in pregnancy involves targeted tests that can include blood markers such as HIV, syphilis, hepatitis B, and rubella immunity, plus additional provider-dependent checks at specific pregnancy stages. These pathways support maternal wellbeing monitoring in the UK.
Why Infection Screening Matters for Maternal Wellbeing
Many of the infections commonly screened for during pregnancy present with no symptoms at all. This is why blood-based testing plays such an important informational role — results can highlight areas that benefit from further medical attention, enabling women and their healthcare teams to act promptly.
Key reasons why maternal infection screening is considered important include:
- Asymptomatic infections may remain undetected without targeted testing
- Some infections are more easily transmitted during specific trimesters
- Early awareness allows expectant mothers to seek appropriate healthcare support promptly
- Results can inform birth planning conversations with midwives or obstetricians
- Testing provides reassurance and supports emotional wellbeing during pregnancy
Practical Insight: Knowing your infection status during pregnancy is not about identifying problems — it is about being informed, prepared, and supported throughout one of life’s most significant experiences.
Key Infections Included in Maternal Screening Panels
Commonly Screened Infections During Pregnancy (Across UK Pathways)
| Infection | Why It Is Screened | Test Type |
|---|---|---|
| HIV | Can be transmitted without symptoms; awareness supports care planning | Blood test (antibody/antigen) |
| Syphilis | May remain asymptomatic; detectable via blood testing | Blood test (VDRL/TPHA) |
| Hepatitis B | Surface antigen testing identifies carrier status | Blood test (HBsAg) |
| Rubella | Immunity check to assess protection levels | Blood test (IgG antibody) |
| Group B Streptococcus (GBS) | Commonly carried without symptoms; screened in later pregnancy | Swab or blood test |
| Chlamydia | May be present without symptoms in younger women | Blood/urine test |
| Toxoplasmosis | Associated with exposure to certain foods or animals | Blood test (IgM/IgG) |
| Cytomegalovirus (CMV) | Often asymptomatic; screened in higher-risk situations | Blood test (IgM/IgG) |
Practical Insight: Not all of the above may be included in a standard NHS antenatal screen. Private infection screening in London allows individuals to access a broader range of tests based on personal health history and informed preference.
Current clinic scope note: Our current API-linked offering is a blood-based antenatal infection and immunity panel, which includes markers such as HIV, syphilis, hepatitis B, hepatitis C, rubella IgG, toxoplasma IgG/IgM, and CMV IgG/IgM. Tests like Group B Streptococcus or some swab/urine STI checks may require other dedicated services depending on pathway.
Who Should Consider Routine Infection Screening?
While NHS antenatal care includes standard infection screening for all pregnant women, there are specific circumstances in which broader or more detailed pregnancy infection testing may be worth considering:
- Women who are planning a pregnancy and wish to understand their baseline immunity and infection status
- Those who have had limited prior sexual health screening
- Women with a history of travel to higher-risk regions
- Individuals who have recently changed sexual partners
- Women with a previous pregnancy affected by infection
- Those who prefer access to a wider panel of tests than the standard NHS offering

How Often Should Infection Screening Be Done During Pregnancy?
The frequency of infection testing in pregnancy can vary depending on individual risk factors and the stage of pregnancy:
- Pre-conception or first trimester: Baseline immunity checks, HIV, syphilis, hepatitis B
- Second trimester: Repeat screening may be considered for some infections depending on clinical history
- Third trimester: Group B Streptococcus screening is commonly offered around weeks 35–37
- As required: Additional testing if symptoms arise or if there has been potential exposure to infection
In the UK, NHS guidance covers several of these at routine booking appointments. However, some women choose to supplement this with private antenatal blood testing to access a more comprehensive panel or prompt written results.
Understanding Your Screening Results
Receiving blood test results can feel daunting, but it is important to understand what they can and cannot tell you.
- Reactive or positive results may suggest the presence of an infection or indicate that further testing is appropriate — they do not constitute a diagnosis on their own
- Negative results can provide reassurance but should always be interpreted alongside your medical history
- Immunity levels (such as rubella IgG) simply indicate whether protective antibodies are present
- All results from our clinic are provided with a clear written report and should be shared with your GP, midwife, or relevant healthcare professional for clinical interpretation
Practical Insight: A screening result is a starting point for informed conversation — not a final verdict. Our nurse-led team provides detailed written reports to support your next steps with your own healthcare professional.

Maternal Infection Screening in London: NHS vs Private Testing
For women based in London, both NHS antenatal screening and private health screening options are available.
| Feature | NHS Antenatal Screening | Private Infection Screening |
|---|---|---|
| Standard infections covered | HIV, syphilis, hepatitis B, rubella | These plus extended panels (e.g. CMV, toxoplasmosis, GBS) |
| Appointment availability | Linked to booking appointments | Flexible, bookable at convenience |
| Turnaround time | Variable | Prompt written reporting; turnaround times confirmed at booking |
| Report format | Through NHS record systems | Written personal report provided |

Frequently Asked Questions
What is routine infection screening during pregnancy?
Routine infection screening during pregnancy involves blood tests designed to detect certain infections that may be present without symptoms. Common tests check for HIV, syphilis, hepatitis B, rubella immunity, and other markers.

Is infection screening during pregnancy available privately in London?
Yes. Private infection screening for pregnant women is available at clinics such as Health Screening Clinic in London. Private testing can offer extended panels, flexible appointments, and prompt written results, complementing the standard NHS antenatal screening pathway.
Do I still need private screening if I’m receiving NHS antenatal care?
The NHS offers valuable standard screening. Private pregnancy infection testing may be worth considering if you wish to access additional tests not routinely offered, receive prompt written reporting, or have personal risk factors that warrant a broader panel. Speak with your midwife about what is included in your NHS care before deciding.
Can infections in pregnancy occur without any symptoms?
Yes. Many infections commonly screened for during pregnancy — including HIV, syphilis, hepatitis B, and chlamydia — can be present without any noticeable symptoms. This is precisely why routine infection screening plays such a valuable educational and informational role in maternal wellbeing.
What happens after I receive my infection screening results?
At Health Screening Clinic, all results are provided as a clear written report. Our nurse-led team does not prescribe treatment or offer clinical management, but we ensure your report is detailed and straightforward to share with your GP, midwife, or relevant healthcare professional for appropriate follow-up.
At what stage of pregnancy should screening be done?
Initial maternal infection screening is typically recommended in the first trimester or at the booking appointment. Some tests, such as Group B Streptococcus, are more relevant in the third trimester. Pre-conception screening is also a valuable option for those planning a pregnancy.
What is Group B Streptococcus (GBS) and why is it screened?
Group B Streptococcus is a bacterial infection that many adults carry without any symptoms. It is most commonly screened for in the third trimester, around weeks 35–37. Awareness of carrier status supports informed conversations with maternity care providers about birth planning options.
Does Health Screening Clinic offer antenatal blood testing?
Health Screening Clinic is a nurse-led private health screening service offering a range of blood tests, including those relevant to maternal wellbeing. We provide testing and written reporting only — we do not offer prescriptions, treatment, or clinical management. Browse our early infection testing in pregnancy guide to find out more.
Is rubella immunity testing important during pregnancy?
Rubella immunity testing checks whether you have protective antibodies against rubella (German measles). Many adults have immunity from childhood vaccination, but checking levels before or during early pregnancy can confirm this, supporting reassurance and any further conversations with a healthcare professional if needed.
How long do private blood test results take at Health Screening Clinic?
Turnaround times vary depending on the specific tests requested. Private blood testing at Health Screening Clinic aims to provide prompt written reporting. Turnaround times vary by test and are confirmed at the time of booking. Results are delivered as a written report for you to share with your own healthcare team.
