Comprehensive TORCH IgG Test – Toxoplasma, Rubella, CMV, Herpes Simplex-II Antibodies Detection

TORCH IgG Test – Toxoplasma IgG, Rubella IgG, Cytomegalovirus IgG, Herpes Simplex-II IgG: Immunity & Exposure Screening

The TORCH IgG Test from Lab Tests Dubai is a vital prenatal and preconception screening panel that detects IgG antibodies against four infections known to cause severe congenital abnormalities if contracted during pregnancy:

• Toxoplasma gondii (Toxoplasmosis)
• Rubella virus
• Cytomegalovirus (CMV)
• Herpes Simplex Virus Type 2 (HSV-2)

Using high-sensitivity chemiluminescence technology, this serum-based test delivers accurate results within just 1 day, helping doctors determine:

• Whether you’re immune (due to past infection or vaccination)
• If you’re susceptible and at risk during pregnancy
• If further IgM testing is needed to rule out recent infection

Available with confidential home blood collection, Lab Tests Dubai makes fetal risk screening fast, reliable, and stress-free—so you can plan your pregnancy with confidence.

Why You Need This Test

If you’re planning a baby or already pregnant, this test could protect your baby from lifelong disability.

You need the TORCH IgG Test if:

• You’re trying to conceive and want to check immunity
• You’re in your first trimester (routine prenatal screening)
• You’ve had unexplained miscarriages or birth defects
• You work with children, animals, or raw meat (high Toxoplasma risk)
• You’re immunocompromised (e.g., HIV, on immunosuppressants)
• You’ve had genital herpes or sexual exposure

IgG antibodies indicate past exposure or immunity:

• Positive IgG = Likely protected
• Negative IgG = Susceptible → need prevention strategies

Early testing allows for:

• Vaccination (for Rubella) before pregnancy
• Lifestyle precautions (e.g., avoiding cat litter, undercooked meat)
• Neonatal monitoring if HSV-2 positive

This is preventive medicine at its most powerful.

Symptoms That Indicate This Test

Consider the TORCH IgG Test if you or your baby may be at risk due to:

• For Toxoplasmosis:

• Exposure to cat feces or raw/undercooked meat

• Flu-like illness during pregnancy

• Fetal intracranial calcifications on ultrasound

• For Rubella:

• No MMR vaccination history

• Rash or joint pain during pregnancy

• History of unvaccinated travel

• For CMV:

• Daycare worker or young children at home

• Mononucleosis-like illness in pregnancy

• Fetal growth restriction or hearing loss

• For HSV-2:

• History of genital herpes

• Partner with HSV-2

• Risk of neonatal herpes during delivery

Even if you feel fine, silent infections can harm your baby—this test gives you peace of mind or early warning.

Natural Production: How IgG Antibodies Reveal Immunity

When your body fights an infection, it produces antibodies:

• IgM – Appears first (acute infection)
• IgG – Develops later, stays for life (immunity)

This test measures IgG only to assess:

• Past infection or vaccination-induced immunity

• Toxoplasma IgG+ → Immune (low risk in pregnancy)

• Rubella IgG+ → Protected (no congenital rubella risk)

• CMV IgG+ → Previously infected (can reactivate; risk to fetus)

• HSV-2 IgG+ → Genital herpes exposure (risk of transmission during delivery)

Note: IgG does not mean active disease—it means exposure or immunity.

What Happens If Untreated or Ignored? Risks to Mother & Baby

Ignoring TORCH susceptibility can lead to devastating congenital conditions:

• Toxoplasmosis → Hydrocephalus, blindness, seizures
• Rubella → Deafness, cataracts, heart defects (Congenital Rubella Syndrome)
• CMV → Hearing loss, microcephaly, developmental delay (most common infectious cause)
• HSV-2 → Neonatal herpes → brain damage, death (if delivered vaginally during active outbreak)

The good news? Most risks are preventable:

• Rubella: Vaccinate before pregnancy
• Toxoplasma: Avoid raw meat, cat litter
• HSV-2: Antiviral therapy (acyclovir) in 3rd trimester
• CMV: Hand hygiene, avoid saliva/urine of young children

This test is your first line of defense.

How to Prepare for the Test

Preparing for the TORCH IgG Test is simple:

• No fasting required
• Continue your regular medications—but inform your doctor
• Avoid testing during acute illness or fever (may affect immune markers)
• Best done before pregnancy or in first trimester

A serum blood sample is collected via standard draw—available at our labs or via home collection.
