Screening Test For Maternal Infections

Screening for maternal infections is an important part of prenatal care. The goal of these tests is to identify any infections that could potentially harm you or your baby. Some infections, such as rubella, can cause birth defects if contracted during pregnancy. Other infections, such as group B streptococci (GBS), can be passed to the baby during delivery and cause serious illness.

What are the symptoms of maternal infections?

Some of the most common symptoms of maternal infections include:

  • Fever: A fever is a common symptom of many infections, including those that can affect pregnant women.
  • Vaginal discharge: Changes in vaginal discharge can be a sign of infection.  If you notice a change in the colour, consistency, or odour of your vaginal discharge, be sure to mention it to your healthcare provider.
  • Painful urination: Pain or burning during urination can be a sign of a urinary tract infection, which is more common during pregnancy.
  • Abdominal pain: Abdominal pain can be a sign of many things, including infections. If you experience abdominal pain during pregnancy, be sure to let your healthcare provider know.
  • Itching or burning: Itching or burning in the vaginal area can be a sign of a yeast infection or bacterial vaginosis, both of which are more common during pregnancy. 
  • Fatigue: Feeling unusually tired or rundown can be a sign of infection, especially if you also have a fever. 
  • Nausea and vomiting: Nausea and vomiting are common during pregnancy, but they can also be a sign of infection.

What are the causes of maternal infections?

Some of the most common causes of maternal infections include:

  • Group B Streptococcus (GBS): GBS is a type of bacteria that is found in the vagina or rectum of up to 30% of pregnant women. GBS can be passed to the baby during delivery and cause serious illness.
  • Urinary tract infections (UTIs): UTIs are more common during pregnancy and can be caused by a variety of bacteria. UTIs can cause symptoms such as painful urination, frequent urination, and fever.
  • Sexually transmitted infections (STIs): STIs such as chlamydia, gonorrhoea, and syphilis can be passed from mother to baby during delivery and cause serious complications.
  • Bacterial vaginosis: Bacterial vaginosis is caused by an overgrowth of bacteria in the vagina. It can cause symptoms such as vaginal discharge and itching.
  • Yeast infections: Yeast infections are caused by an overgrowth of yeast in the vagina. They can cause symptoms such as itching and burning.
  • Viral infections: Viral infections such as rubella, cytomegalovirus (CMV), and herpes simplex virus (HSV) can cause serious complications during pregnancy.
  • Foodborne illnesses: Foodborne illnesses such as listeriosis and toxoplasmosis can be contracted through contaminated food and cause serious complications during pregnancy.

List of infections

To screen for maternal infections, your healthcare provider may recommend a variety of tests. These tests can include blood tests, urine tests, and vaginal swabs. Some of the specific infections that may be screened for include:

  • Rubella
  • Hepatitis B
  • Syphilis
  • Chlamydia
  • Gonorrhea
  • Group B Streptococcus (GBS)


Prompt treatment of maternal infections is important to ensuring a healthy pregnancy and delivery. Treatment options for maternal infections will vary depending on the type and severity of the infection but may include antibiotics, antiviral medication, antifungal medication, prevention of transmission, and supportive care. It's important to talk to your healthcare provider about any concerns or symptoms you may have during pregnancy.

In conclusion, screening for maternal infections is an important part of prenatal care. These tests can help identify infections that could harm you or your baby and allow for appropriate treatment to be provided. If you have any questions or concerns about screening for maternal infections, be sure to discuss them with your healthcare provider.

2. Are there any treatments for Thalassemia or Sickle Cell Disease?

Yes, some treatments for both conditions include medications to reduce symptoms and complications, blood transfusions, and stem cell transplants.

3. What kinds of tests can be used to detect Thalassemia or Sickle Cell Disease?

Haemoglobin electrophoresis, haemoglobin F measurement, DNA mutation analysis, and red cell indices are all commonly used to diagnose these conditions.

4. Can diet or lifestyle changes improve symptoms of either disorder?

Yes, in some cases, making changes such as avoiding exposure to cold temperatures or increasing iron intake may help alleviate symptoms.

5. How accurate is genetic testing for Thalassemia and Sickle Cell Disease?

The accuracy of genetic tests depends on the type of test used; however, in general, they have high sensitivity and specificity.

6. Is it possible to accurately predict the severity of Thalassemia or Sickle Cell Disease based on genetic testing?

Yes, in some cases, some mutations can be used to predict the severity of the condition. However, other factors may also influence disease severity.
