Pre-Marital Health Checkup: 10 Tests Every Couple Should Consider Before Marriage

1. Complete Blood Count (CBC)

A Complete Blood Count, or CBC, is one of the common blood tests used to assess overall health. It measures different components of your blood, including red blood cells, white blood cells, haemoglobin, and platelets.

Why is it important?

• It can help detect anaemia, which may cause tiredness, weakness, and dizziness.
• It provides information about red blood cells that may suggest an inherited blood condition.
• It can identify changes in white blood cells and platelets that may need further evaluation.

Anaemia is particularly important to identify before pregnancy because low haemoglobin levels may require treatment and monitoring.

A CBC alone cannot diagnose every blood disorder. If the results suggest an underlying condition, a doctor may recommend additional tests.

2. Blood Group and Rh Factor Test

Knowing your blood group is useful for future medical care. This test identifies whether your blood group is A, B, AB, or O and whether you are Rh-positive or Rh-negative.

Why is it important?

Blood group information can be useful in emergencies when a blood transfusion is needed. The Rh factor is also relevant during pregnancy.

If a pregnant woman is Rh-negative and the baby is Rh-positive, Rh incompatibility can sometimes cause complications. Medical teams can usually prevent these problems through appropriate testing, monitoring, and preventive treatment.

Remember that different blood groups do not make a couple incompatible for marriage. This test is mainly useful for medical planning, particularly if pregnancy is planned.

3. Thalassemia and Sickle Cell Screening

Thalassemia and sickle cell disease are inherited blood disorders. A person may carry a genetic change without experiencing significant symptoms.

This makes carrier screening an important consideration, especially for couples with a family history of these conditions or other relevant risk factors.

Why is it important?

If both partners carry certain disease-causing variants affecting the same inherited blood condition, their children may have a risk of developing that condition.

A doctor may recommend a CBC, haemoglobin analysis, high-performance liquid chromatography (HPLC), or other appropriate tests to identify carrier status.

For example, when both partners carry beta-thalassemia trait, each pregnancy has a 25% chance of resulting in a child with beta-thalassemia major, a 50% chance of a child who is a carrier, and a 25% chance of a child who does not inherit either altered copy.

These probabilities apply to each pregnancy independently. Genetic counselling helps couples understand their individual results and reproductive options.

4. Blood Sugar Test

Diabetes can develop gradually, and some people may not experience noticeable symptoms in the early stages.

A fasting blood glucose test or HbA1c test can help assess blood sugar levels. The doctor will recommend the appropriate test based on age, symptoms, family history, and other risk factors.

Why is it important?

• It can help identify diabetes or elevated blood sugar levels.
• It supports early treatment and lifestyle changes.
• It helps couples understand health factors that may matter when planning a pregnancy.

An HbA1c test estimates average blood sugar levels over approximately the previous two to three months. A fasting glucose test measures blood sugar after a period without food.

Abnormal results may require confirmation or further assessment. Identifying diabetes early can help reduce the risk of long-term complications.

5. Thyroid Function Test

The thyroid gland produces hormones that regulate metabolism, energy use, and several other body functions. When the thyroid produces too much or too little hormone, it can affect overall health.

A thyroid-stimulating hormone (TSH) test is commonly used to assess thyroid function. Additional tests, such as free T4, may be needed depending on the result.

Why is it important?

Thyroid disorders can cause symptoms such as fatigue, unexplained weight changes, changes in heart rate, or menstrual irregularities. Some people may have no obvious symptoms.

Thyroid problems can also affect fertility and pregnancy when they are untreated or poorly controlled.

Testing is particularly worth discussing if either partner has symptoms, a history of thyroid disease, or other relevant risk factors. Not everyone needs a thyroid profile simply because they are getting married.

6. HIV Screening Test

HIV is a virus that affects the immune system. A person can live with HIV for years without obvious symptoms, which is one reason testing can be important.

An HIV screening test may be considered as part of sexual health planning, depending on individual circumstances and informed choice.

Why is it important?

• It helps identify HIV infection so that appropriate care can begin.
• Effective treatment can help people with HIV live long, healthy lives.
• Treatment that maintains an undetectable viral load prevents sexual transmission of HIV.
• Early diagnosis and treatment can help reduce the risk of transmission to a baby during pregnancy and childbirth.

A reactive screening result does not, by itself, confirm HIV infection. Additional testing is needed according to the recommended diagnostic process.

HIV testing should be voluntary, confidential, and supported by appropriate counselling. Couples should approach the conversation with respect rather than stigma.

7. Hepatitis B and Hepatitis C Screening

Hepatitis B and hepatitis C are viral infections that affect the liver. Some people have these infections without obvious symptoms, and untreated infections may lead to long-term liver damage.

A doctor may recommend a hepatitis B surface antigen (HBsAg) test and hepatitis C antibody screening, followed by additional testing when required.

Why is it important?

• It can help identify an infection that needs medical evaluation.
• It supports timely treatment or monitoring.
• Hepatitis B screening can help guide vaccination and prevention decisions.
• It helps healthcare professionals plan appropriate precautions during pregnancy and childbirth when relevant.

Hepatitis B can be prevented through vaccination. If a person tests positive, the next steps depend on the results and clinical assessment.

Testing recommendations vary according to personal risk factors, previous testing, vaccination history, and pregnancy plans.

8. Syphilis Screening Test

Syphilis is a sexually transmitted infection caused by bacteria. It can sometimes remain unnoticed because its early symptoms may be mild or may disappear without the infection being cured.

Blood tests such as VDRL or RPR are commonly used for screening, with additional testing when necessary.

Why is it important?

• It helps identify an infection that may otherwise go untreated.
• Early diagnosis allows appropriate treatment.
• It can help prevent serious complications.
• Treating syphilis before pregnancy can reduce the risk of transmission to the baby.

Syphilis is treatable, particularly when detected early. However, a screening result must be interpreted by a healthcare professional because other conditions can sometimes cause a false-positive result.

Sexual health screening should be based on informed consent, medical advice, and individual circumstances.

9. Fertility and Reproductive Health Assessment

A fertility assessment is not the same as a routine blood test. It may involve a medical history, physical examination, and specific investigations depending on the concerns of each partner.

For women, a doctor may recommend an assessment of menstrual health, ovulation, or reproductive organs when indicated. Tests such as anti-Müllerian hormone (AMH) or pelvic ultrasound may be appropriate in selected cases.

For men, an assessment may include a medical history and, when indicated, semen analysis to evaluate sperm count, movement, and shape.

Why is it important?

A reproductive health assessment may help identify certain conditions that could affect conception or pregnancy. It can also help couples understand when further evaluation may be useful.

However, no single fertility test can guarantee whether someone will or will not be able to have children. For example, AMH alone cannot predict the likelihood of natural conception.

If you are planning a pregnancy soon, have irregular periods, have a known reproductive condition, or have concerns about fertility, consult a qualified healthcare professional about appropriate testing.

10. Vitamin and Nutritional Deficiency Tests

Nutritional deficiencies can affect energy levels, blood health, and general well-being. Depending on symptoms and medical history, a doctor may recommend testing for iron deficiency, vitamin B12 deficiency, or vitamin D deficiency.

Common investigations may include serum ferritin, vitamin B12, and 25-hydroxyvitamin D.

Why is it important?

• Iron deficiency can contribute to anaemia and fatigue.
• Vitamin B12 deficiency can affect red blood cells and nerve function.
• Vitamin D deficiency can affect bone health and muscle function.

Identifying a deficiency allows the doctor to recommend suitable dietary changes, supplements, or further investigations.

These tests are not compulsory for every couple. They are more useful when there are symptoms, dietary risk factors, known deficiencies, or other clinical reasons to investigate.
