What is TORCH testing?
TORCH is a group of infections that may affect pregnancy in certain situations.It includes:
- T – Toxoplasmosis
- O – Other infections (such as syphilis and varicella)
- R – Rubella
- C – Cytomegalovirus (CMV)
- H – Herpes simplex virus
What Is the Relevance of TORCH Infection Management in High-Risk Pregnancies?
This may include:| Toxoplasmosis | • Rare, but may be considered in recurrent pregnancy loss • Risk is higher with exposure to raw meat, soil, or cat faeces |
| HIV | • Not a common cause of miscarriage • Screening is important for the mother and baby’s health |
| Parvovirus B19 (Fifth Disease) | • Rare cause of miscarriage • Considered if there is a history of foetal loss or anaemia • Testing only if symptoms or suspected exposure |
| Syphilis | • Important and treatable cause of poor pregnancy outcomes • Can lead to miscarriage or stillbirth if untreated • Routinely screened in pregnancy, especially with a bad obstetric history (BOH) |
| Varicella (Chickenpox) | • Rare contributor to pregnancy loss |
| Rubella | • Rare due to widespread immunity • May be relevant if not vaccinated |
| Cytomegalovirus (CMV) | • Not a routine cause of recurrent miscarriage • Considered in specific cases with abnormal foetal findings |
| Herpes Simplex Virus (HSV) | • Not typically linked to miscarriage • More relevant for delivery-related infection risk |
| Other Diagnostic Tests | • Viral cultures (saliva, blood, urine, etc.) • PCR tests for viral DNA/RNA • Imaging (ultrasound, CT, MRI) if needed |
What Is the Purpose of the TORCH Screening After Miscarriage?
It is a simple blood test that is prescribed for the following purposes:- Check for antibodies in your body
- Suggest past or recent exposure
When May Your Doctor Decide to Screen You for TORCH Agents?
Your doctor will suggest a screening test for TORCH infection depending on various factors. These may include:- Your individual risk level based on history
- The region or environment you live in (some infections are more common in certain areas)
- The type of infection suspected
- Number of previous miscarriages, especially if recurrent
- Any symptoms during pregnancy, such as fever, rash, or swollen glands
- Exposure history, like contact with raw meat, unpasteurised dairy, or cat litter
- Ultrasound findings, if there are signs of foetal abnormalities
- Your immunity status, especially for infections like rubella
- Presence of chronic medical conditions that may affect immunity
- Timing in pregnancy when symptoms or concerns appeared
Can Infections Really Cause Miscarriage?
Yes, sometimes. But not as often as many people assume.In fact, certain infections can increase the risk of:
- Early pregnancy loss
- Problems in foetal development
- Growth issues
- Most miscarriages happen due to chromosomal changes
- These are usually not preventable
How Can TORCH Screening Help Manage High-Risk Pregnancies?
Your doctor may consider TORCH testing as part of a broader evaluation in selected cases. So, when you plan your next pregnancy after the diagnosis, your doctor can guide you better. You can anticipate the following:| Attributes | How can it help |
| Toxoplasmosis Screening | • Not a routine test in low-risk individuals • Done if exposure risk is present (cats, raw meat) • Blood test checks IgG, IgM, and IgA antibodies • Repeat testing for rising antibody levels • PCR may detect Toxoplasma DNA |
| Understanding Antibodies | • The immune system produces IgA, IgG, and IgM • These help fight infection • Levels help assess the timing of infection |
| HIV Screening | • Routine screening in pregnancy • May be repeated before 36 weeks in high-risk cases |
| Syphilis Screening | • Routine blood test • Repeated at 28 weeks and at delivery if at risk |
| Parvovirus B19 & Varicella | • No routine screening • Tested only if symptoms (fever, rash) • Helps guide treatment if infection occurs |
| Rubella Screening | • Blood test if infection suspected |
| CMV Screening | • Tested only if symptoms present |
| Herpes Screening | • No routine screening • Pregnancy monitored if history present |
How Can You Prepare for Your Next Pregnancy?
Although you may not have all the answers right away, small, steady steps can help you feel more in control.You can gently focus on the following:
- Following and trusting your doctor
- Taking folic acid as advised
- Managing existing health conditions
- Eating freshly cooked, balanced meals
- Practising basic infection prevention:
- Wash your hands regularly
- Avoid eating raw or undercooked food
- Maintain good food hygiene
Sometimes, the most helpful step is to follow a personalised plan guided by your doctor for favourable outcomes in the future.

FAQs on Should You Get a TORCH Test After a Miscarriage? All You Need To Know
- Are TORCH infections common?
Although TORCH infections are not very common, they can cause certain medical problems that can affect the development of babies. Some studies also suggest a link between TORCH infection and spontaneous pregnancy losses. - Can TORCH infections be the cause of miscarriages?
In some cases, preterm delivery, miscarriage, or stillbirth may occur as a result of TORCH infections. The timing of infection, the type of infection, and the efficacy of treatment all play a significant role in such a scenario. - What is the meaning of a TORCH infection with an IgG-positive report?
A positive IgG usually indicates past exposure or immunity. However, your doctor may interpret it along with other tests or repeat levels if needed.
