Introduction
A wedding marks the beginning of a new chapter in life. While couples spend months planning their wedding celebrations, outfits and future home, one important aspect of preparation often gets overlooked: health and wellness.
A premarital health checkup gives couples an opportunity to understand their health status, identify certain medical conditions and discuss future family-planning goals with a healthcare professional.
It may include basic blood investigations, screening for selected infections, genetic carrier testing and other assessments depending on individual medical history and reproductive plans.
However, there is no single mandatory list of tests that every couple must undergo before marriage. The appropriate investigations depend on factors such as age, family history, lifestyle, existing health conditions and plans for pregnancy.
In this guide, we explore the important premarital health tests couples may consider, why they matter and how early health awareness can support a healthier future together.
What is a Premarital Health Checkup?
A premarital health checkup is a preventive health assessment conducted before marriage. It helps individuals understand their current health status and identify conditions that may require medical attention or follow-up.
It may include:
- General health assessment
- Blood tests to check for anaemia and other health concerns
- Screening for selected infectious diseases
- Blood group and Rh typing when relevant to future pregnancy planning
- Genetic carrier screening when indicated
- Assessment of diabetes, thyroid or other medical conditions based on risk factors
- Preconception counselling for couples planning a pregnancy
The purpose is not to determine whether two people are medically compatible for marriage. Instead, it is about informed health decisions, early intervention and planning for the future.
1. Complete Blood Count (CBC) – Understanding Overall Blood Health
A Complete Blood Count (CBC) is a commonly recommended blood investigation that measures different components of blood.
It includes:
- Haemoglobin (Hb)
- Red blood cell (RBC) count
- White blood cell (WBC) count
- Platelet count
- Red blood cell indices, such as MCV and MCH
Why is a CBC important before marriage?
A CBC can help identify:
- Anaemia
- Possible iron deficiency patterns
- Abnormal white blood cell counts
- Platelet abnormalities
- Red blood cell patterns that may suggest an inherited blood disorder
Anaemia may be associated with nutritional deficiencies, blood loss or other medical conditions. Identifying the possible cause allows appropriate evaluation and treatment.
Important: A CBC alone cannot diagnose every type of anaemia or inherited blood disorder. Additional investigations may be needed depending on the findings.
2. Blood Group and Rh Factor – Important for Future Pregnancy Planning
Blood group testing identifies whether a person has blood group A, B, AB or O and whether their Rh factor is positive or negative.
For example:
- A positive
- B negative
- AB positive
- O negative
Why does blood group matter?
Knowing your blood group can be useful for medical records and situations where blood transfusion may be required.
Rh factor is particularly relevant during pregnancy.
If a pregnant woman is Rh-negative and the developing baby is Rh-positive, Rh incompatibility may occur. Without appropriate medical care, this can lead to complications in a pregnancy.
Healthcare professionals can assess the situation and recommend preventive treatment, such as anti-D immunoglobulin, when indicated.
Important: Different blood groups or Rh factors do not make two people incompatible for marriage. Blood group testing is not a test of marital compatibility.
3. Thalassemia and Sickle Cell Screening – Understanding Genetic Risks
Thalassemia and sickle cell disease are inherited blood disorders that affect haemoglobin, the protein responsible for carrying oxygen in red blood cells.
Some individuals carry a genetic change without experiencing significant symptoms. They may not know they are carriers unless they undergo appropriate testing.
Why is carrier screening important?
If both partners carry certain disease-causing variants affecting the same inherited condition, there may be a risk of having a child affected by that condition.
For example, when both biological parents carry a relevant beta-thalassemia variant, each pregnancy can have:
- 25% chance of an affected child
- 50% chance of a child who is a carrier
- 25% chance of a child who does not inherit either variant
These probabilities apply to each pregnancy and assume both partners carry the relevant variants in the usual autosomal recessive inheritance pattern.
Which tests may be recommended?
Doctors may consider:
- Complete Blood Count (CBC) with red blood cell indices
- Peripheral blood smear, when indicated
- Haemoglobin electrophoresis or HPLC
- Genetic testing in selected situations
Carrier screening is especially relevant when there is a family history of thalassemia, sickle cell disease or another inherited blood disorder.
If one partner is found to be a carrier, the other partner may be offered testing. If both carry relevant variants, genetic counselling can explain reproductive risks and available options.
Important: Being a carrier does not automatically mean that a person has the disease or cannot have a healthy child. Screening should support informed decisions, not discrimination or stigma.
4. HIV Test – Knowing Your Status
HIV (Human Immunodeficiency Virus) affects the immune system and can be transmitted through certain body fluids, including during unprotected sexual contact.
An HIV screening test may be considered as part of sexual health or preconception care, depending on individual circumstances and preferences.
Why is HIV testing important?
Knowing one's HIV status can help:
- Identify an infection early.
- Access appropriate treatment and medical care.
- Reduce the risk of transmission to a partner.
- Support safer pregnancy planning and reduce the risk of transmission to a baby.
Which test is used?
An HIV screening test may detect HIV antibodies and, depending on the test, the p24 antigen.
A reactive screening result requires further testing according to the recommended diagnostic algorithm. It should not be treated as a confirmed diagnosis based on a screening result alone.
Testing should be voluntary, confidential and accompanied by appropriate counselling.
5. Hepatitis B and Hepatitis C Tests
Hepatitis B and hepatitis C are viral infections that affect the liver. Both can sometimes remain unnoticed for years without obvious symptoms.
Hepatitis B – HBsAg Test
The HBsAg (Hepatitis B surface antigen) test is commonly used to screen for current hepatitis B infection.
A positive result requires further evaluation with additional tests, which may include:
- Anti-HBc
- Anti-HBs
- HBeAg, when appropriate
- HBV DNA testing
Knowing hepatitis B status is important because the infection can be transmitted through sexual contact and from an infected mother to her baby.
Vaccination is an effective way to prevent hepatitis B infection in people who are not immune.
Hepatitis C – Anti-HCV Test
The anti-HCV test checks for antibodies against the hepatitis C virus.
A reactive result does not necessarily mean that the infection is currently active. HCV RNA testing is generally required to confirm current infection.
Hepatitis C is mainly transmitted through blood exposure. Sexual transmission is possible but is less common in some populations and depends on individual circumstances.
Identifying infection allows a person to access medical evaluation and treatment.
6. Syphilis Screening – RPR or VDRL Test
Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum.
It can affect multiple organs if left untreated. Some people may not notice symptoms, particularly during certain stages of infection.
Why consider syphilis screening?
Testing may be recommended based on sexual history, exposure, symptoms, local prevalence or pregnancy plans.
Common screening tests include:
- RPR (Rapid Plasma Reagin)
- VDRL (Venereal Disease Research Laboratory)
Reactive results generally require confirmatory testing using an appropriate treponemal test.
Early diagnosis and appropriate treatment can prevent complications and reduce the risk of transmission.
7. Blood Sugar Tests – Checking Diabetes Risk
Diabetes can develop without obvious symptoms. A premarital health assessment may provide an opportunity to evaluate blood glucose levels, particularly in people with risk factors.
Doctors may recommend the following tests:
Fasting Blood Glucose (FBS)
Measures blood glucose after an overnight fast, usually at least eight hours.
It helps assess blood sugar regulation.
HbA1c Test
Measures glycated haemoglobin and reflects average blood glucose levels over approximately two to three months.
Common diagnostic thresholds for non-pregnant adults are:
| HbA1c result | Interpretation |
| Below 5.7% | Normal range |
| 5.7%–6.4% | Prediabetes range |
| 6.5% or higher | Diabetes range |
In the absence of clear symptoms or unequivocal hyperglycaemia, an abnormal result generally requires confirmation.
Why are these tests useful?
Identifying elevated blood glucose can help people receive timely medical advice, make lifestyle changes and plan for pregnancy when relevant.
Not every healthy young adult requires every diabetes test before marriage. Screening decisions depend on age, weight, family history and other risk factors.
8. Thyroid Function Test – Understanding Hormonal Health
The thyroid gland produces hormones that help regulate metabolism, energy use and several body functions.
Thyroid disorders may affect both men and women.
Which tests may be recommended?
A thyroid assessment may include:
- TSH (Thyroid Stimulating Hormone)
- Free T4, when indicated
- Free T3, in selected clinical situations
Why is thyroid testing important?
Abnormal thyroid function may be associated with:
- Changes in energy levels
- Unexplained weight changes
- Menstrual irregularities
- Changes in heart rate
- Fertility-related concerns in some individuals
Thyroid testing is particularly relevant when symptoms, medical history or pregnancy-planning considerations suggest a possible thyroid disorder.
A thyroid profile is not automatically required for every asymptomatic couple.
9. Vitamin D and Vitamin B12 Tests – Checking Nutritional Health
Vitamin deficiencies can affect general health, energy levels and normal body functions.
Vitamin D Test
The 25-hydroxy vitamin D test measures vitamin D status.
Low vitamin D levels may be associated with:
- Bone and muscle discomfort
- Muscle weakness
- Increased risk of poor bone health
Testing may be considered in people with symptoms or risk factors for deficiency.
Vitamin B12 Test
Vitamin B12 is important for red blood cell production and normal nerve function.
Low levels may contribute to:
- Fatigue
- Weakness
- Tingling or numbness
- Certain types of anaemia
- Neurological problems
People following restrictive diets, particularly those who consume little or no animal-derived food, may have an increased risk of deficiency.
Important: Vitamin D and B12 testing should be based on clinical need and risk factors rather than automatically included in every premarital package.
Many couples have questions about fertility before getting married. However, it is important to understand that fertility cannot be accurately predicted through a single blood test.
Routine fertility testing is generally not necessary for every asymptomatic person before marriage.
Investigations may be recommended when there are symptoms, a known reproductive health condition, previous fertility concerns or difficulty conceiving.
For women
Depending on the medical history, a doctor may recommend:
- Pelvic ultrasound
- Hormonal tests, when indicated
- Evaluation of menstrual irregularities
- Assessment of known reproductive conditions such as PCOS or endometriosis
Tests such as AMH (Anti-Müllerian Hormone) may be useful in specific fertility assessments, but AMH alone cannot reliably predict natural conception or guarantee future fertility.
For men
When clinically indicated, investigations may include:
- Semen analysis
- Hormonal assessment
- Physical examination
- Additional investigations based on the findings
A semen analysis evaluates sperm concentration, motility, morphology and other semen characteristics. It is commonly used during an infertility evaluation, not as a universal test for every man before marriage.
Remember: A normal fertility-related test does not guarantee future fertility, and an abnormal result does not automatically mean infertility.
11. Additional Health Assessments Couples May Consider
Apart from blood investigations, certain other assessments may be useful depending on individual needs.
| Assessment | Why it may be considered |
| Blood pressure | Helps identify hypertension |
| BMI and weight assessment | Provides information about weight-related health risks |
| Liver Function Test (LFT) | May be recommended for suspected or known liver conditions |
| Kidney Function Test (KFT) | May be advised for people with kidney-related risk factors |
| Lipid profile | Helps assess cholesterol and cardiovascular risk |
| Urine routine examination | May help evaluate selected urinary or kidney-related concerns |
| Rubella immunity assessment | May be relevant before pregnancy if vaccination or immunity status is uncertain |
Preconception counselling can also include reviewing vaccination status, current medications, nutrition, lifestyle habits and any existing medical conditions.
For people planning pregnancy, a healthcare professional may recommend folic acid supplementation before conception and during early pregnancy according to current guidance.

When Should Couples Get a Premarital Health Checkup?
There is no fixed number of days before marriage when every test must be completed.
However, couples who are planning a pregnancy may benefit from preconception counselling several months before trying to conceive.
Starting early provides time to:
- Review medical and family history.
- Identify and manage existing health conditions.
- Review medications and supplements.
- Check relevant vaccination status.
- Consider genetic carrier screening.
- Discuss reproductive health concerns.
- Make informed decisions about pregnancy planning.
Some investigations may require follow-up, confirmatory testing or specialist consultation, so it is helpful not to leave health assessments until the last few days before the wedding.
Why Is Premarital Health Awareness Important?
A premarital health checkup is not about judging a person's health or deciding whether someone is suitable for marriage. It is an opportunity for both partners to approach their future with awareness and mutual understanding.
It can help couples:
1. Understand existing health conditions
Some conditions may remain undiagnosed because symptoms are mild or absent.
2. Identify certain infections early
Appropriate screening can help people access treatment and reduce transmission risks.
3. Understand inherited health risks
Carrier screening can help couples understand the possibility of passing certain genetic conditions to their children.
4. Prepare for a healthy pregnancy
Preconception care allows couples to address medical conditions, nutritional needs and vaccination status before pregnancy.
5. Build informed health habits together
Discussing health, lifestyle and family-planning goals can support better long-term health decisions.
Conclusion
A premarital health checkup is an opportunity for couples to understand their health, discuss future family-planning goals and identify medical concerns that may benefit from early attention.
From CBC and blood group testing to selected infection screening and genetic carrier assessment, the right investigations depend on individual health history and reproductive plans. Not every test is necessary for every person, and no single health report can predict the future of a relationship or guarantee a healthy pregnancy.
A thoughtful approach to premarital health screening can help couples begin their next chapter with greater awareness, informed choices and a shared commitment to well-being.
