Tests before planning pregnancy: what tests to take and why it's important

The period of pregnancy planning often becomes a moment of rethinking one's own health. It is at this time that a woman or couple begins to pay more attention to their lifestyle, nutrition, and well-being. Pre-pregnancy check-up allow you to avoid unexpected difficulties, correct possible violations and create the best conditions for the future baby.

All of the tests listed below are recommended by international organizations, including the WHO and CDC, as part of pre-pregnancy preparation.

Why are tests needed before pregnancy?

Pregnancy affects all body systems. To make this period as smooth as possible, it is important to determine in advance:

• is there a shortage iron, vitamins or metabolic disorders
• whether the thyroid gland is functioning properly
• are there any chronic or hidden infections
• is there enough hormonal support for the onset and development of pregnancy?
• are there risks of hereditary and thrombotic conditions

Even minor violations can affect conception or early pregnancy, so timely examination makes it possible to correct everything in time.

Basic tests that are recommended for every woman

These studies provide a general idea of the state of the body.

Complete blood count

Allows you to detect anemia, inflammation, and possible clotting disorders.

General urine analysis

Shows kidney function and the presence of urinary tract infections.

Biochemical blood test

Reflects the condition of the liver, kidneys, electrolyte balance and protein levels.

Glucose and glycated hemoglobin

Help assess the risk of developing gestational diabetes.

Ferritin

Shows iron stores. Ferritin deficiency before pregnancy significantly increases the risk of anemia in the first trimester.

Vitamin D

Important for immunity, bones, hormonal balance, and fetal development.

Blood type and Rh factor

Necessary for the prevention of Rh conflict.

Infection tests that are important before pregnancy

Some infections can affect pregnancy or fetal development. Therefore, it is important to know at the planning stage whether there is immunity or an active infection.

TORCH complex

Includes toxoplasma, rubella, cytomegalovirus, and herpes virus. It is especially important to determine whether there are antibodies to rubella, as infection during pregnancy is dangerous for the fetus.

HIV, hepatitis B and C, syphilis

Required for all women planning a pregnancy.

Sexually transmitted infections

Chlamydia, mycoplasma, and ureaplasma can affect conception and cause complications in the first trimester.

Hormonal tests before pregnancy

The hormonal system largely determines the ability to become pregnant and successfully carry a child.

TSH and free T4

Thyroid function indicators. According to the Mayo Clinic, even minor thyroid dysfunction can interfere with conception.

Prolactin

Excess prolactin can suppress ovulation.

Progesterone

Assessed in the second phase of the cycle. Lack of progesterone can make implantation difficult.

LH, FSH

They show the state of ovarian reserve and ovulatory function.

Anti-Müllerian hormone (AMH)

Reflects the number of follicles and reproductive potential.

Additional tests recommended by a doctor

Not everyone needs them, but they may be prescribed if there are indications:

• insulin and HOMA-IR index
• folic acid and B vitamins
• coagulogram
• antibodies to thyroid peroxidase
• genetic tests for thrombophilia
• HPV test

Such studies are important for women with a complicated history or previous pregnancy losses.

Tests for men before planning pregnancy

Pregnancy planning involves both partners. WHO recommends that men undergo:

• spermogram
• sperm DNA fragmentation test
• general blood test
• tests for infections
• if necessary — hormonal profile

Sperm quality affects not only the likelihood of conception, but also the health of the embryo.

How to prepare for tests before pregnancy

For accurate results, it is advisable to:

• donate blood on an empty stomach
• do not drink alcohol 48 hours before the tests
• avoid severe stress and lack of sleep
• give hormones on strictly defined days of the cycle
• do not take vitamins without consultation
• start taking folic acid 1–3 months before conception

Such simple steps significantly improve the quality of examinations.

By completing the examination at the planning stage, a woman gets the opportunity to timely adjust her condition, make the pregnancy predictable and calm, and most importantly, support her own health even before the changes occur. A well-prepared body adapts more easily to future loads, which means more strength and confidence on the way to the desired child.
