What is a prenatal check-up?

A prenatal check-up is a wide range of diagnostic tests recommended for the early diagnosis of diseases or developmental abnormalities in pregnancy.

The tests check the overall state of health of the mother-to-be to avoid complications during pregnancy or childbirth. Furthermore, they detect factors that may affect the development and health of the embryo.

Except for microbiological tests, the prenatal check-up also includes ultrasound examinations, usually performed by a gynecologist.

Some cases require specialized invasive examinations, such as trophoblast retrieval or amniocentesis to check for genetic and chromosomal abnormalities.

Prenatal check-up aims to ensure the health of the mother and the baby through the early diagnosis and treatment of any potential problems.

What microbiological tests does prenatal check-up for women include?

A woman who is planning to become pregnant or is in the first trimester of pregnancy is advised to do the following tests:

1. General blood count, iron levels, and ferritin levels

A check-up for the woman’s general state of health. It may reveal possible anemia or other conditions that need to be treated.

2. Urinalysis and urine culture

Screening for diseases or infections of the urinary system that can affect the health and development of the baby.

3. Hemoglobin electrophoresis and sickle cell test

Screening for the Mediterranean anemia stigma and the sickle cell disease. The tests are recommended to take place before the woman gets pregnant or immediately after confirmation of pregnancy.

4. Blood type and Rhesus test

Screening for the mother’s blood type and the Rhesus factor of both parents. The aim is to prevent any incompatibility in the blood of the mother and the embryo.

In case of incompatibility, indirect Coombs tests take place regularly and the mother receives special treatment during the pregnancy. Without timely treatment, there is a high risk of severe anemia and hemolytic jaundice of the baby.

5. Blood sugar check

The measurement of blood sugar levels at the beginning of pregnancy and a blood sugar curve in the second trimester constitute a pre-symptomatic screening for gestational diabetes. Gestational diabetes is a type of diabetes that can develop during pregnancy and cause complications.

6. TSH check

The measurement of thyroid-stimulating hormone (TSH) in the blood monitors the proper functioning of the thyroid gland. During pregnancy, the thyroid plays an important role, especially in the first 10-12 weeks of pregnancy.

Hypothyroidism is associated with an increased risk of miscarriage, while it has negative effects on the health of the embryo and mother.

7. Screening for STDs (Sexually Transmitted Diseases)

The screening for sexually transmitted diseases minimizes the risk of transmission to the embryo and ensures the mother’s protection.

It includes the following diagnostic tests:

  • Australian antigen and hepatitis C antibodies: Test for possible hepatitis B and hepatitis C infection.
  • VDRL reactive: Serological test for syphilis.
  • HIV I and II: A blood test to detect the AIDS virus.

8. Rubella IgG and IgM antibodies

Screening for the existence of immunity against the rubella virus. In case of non-immunity, vaccination is recommended at least one month before the childbearing attempt begins.

In the first trimester of pregnancy, rubella can cause serious fetal abnormalities, such as deafness, heart damage, and intellectual disability.

9. Toxoplasma IgG & IgM Antibodies

Screening for toxoplasma infection. Toxoplasma is a parasite transmitted mainly by the feces of infected cats, raw meat, or unpasteurized dairy products.

Infection of the embryo in the first trimester can cause miscarriage, intellectual disability, and visual disorders.

10. CMV IgG & IgM antibodies

Screening for old or new cytomegalovirus infection. In the first trimester of pregnancy, cytomegalovirus infection can affect the brain, the auditory nerve and the liver, and cause intellectual disability and deafness.

11. Molecular control of cystic fibrosis

Cystic fibrosis is the most common inherited disease of white populations. If both parents are carriers of the mutation for this disease, there is a 25% chance that an infected child will be born.

Molecular testing is done by taking a blood sample or genetic material from inside the cheeks.

What does a prenatal check-up for men include?

In many cases, the father-to-be may also need to take a prenatal test.

The prenatal check-up for men may be associated with a pathological result in the partner’s examinations or with the existence of a history of inherited genetic diseases.

Finally, prenatal testing includes fertility testing for couples trying to conceive. In the case of men, this means tests such as:

  • Sperm analysissperm diagram. This test checks the sperm volume, pH, sperm count, mobility, and morphology.
