What Medical Screenings do Clinics Require Before Matching a Surrogate?
Surrogacy is a journey that begins long before any embryo transfer, starting with comprehensive medical and psychological screenings to ensure the health, well-being, and safety of everyone involved. No clinic will match a surrogate until she has passed through a rigorous evaluation process that protects the baby, the carrier, and the intended parents.

In this article, we’ll walk you through the essential medical screenings required before matching a surrogate. You’ll learn about the tests, assessments, and standards clinics follow, including physical health checks, infectious disease panels, reproductive evaluations, and partner screenings, to meet both ethical guidelines (e.g., ASRM) and legal obligations. By understanding these steps, you’ll see how they form the foundation of a safe, responsible, and successful surrogacy experience.

Initial Physical & Lifestyle Assessment
Before a surrogate is matched with intended parents, clinics perform a thorough physical and lifestyle evaluation to ensure she can safely carry a pregnancy:
General Health Screening
- Age & BMI
Clinics follow ASRM guidelines: surrogates are typically between 21–45 years old and have a BMI under 30–35. - Pregnancy History
A prior uncomplicated full-term birth is required, with limits on total deliveries (e.g., no more than 3-5 and up to 3 C-sections). - Vital Signs & Medical History
Blood pressure, heart rate, and chronic health conditions (like hypertension) are carefully evaluated to assess safety during pregnancy .

Lifestyle Factors
- Substance Use Screening
Urine or blood tests confirm a tobacco-free, drug-free, and moderate-alcohol lifestyle and these are non-negotiable conditions. - Home Environment Evaluation
Clinics assess whether the surrogate has stable housing, emotional support, and family or partner backing, which directly impacts pregnancy outcome

Infectious Disease & Blood Testing
Ensuring health and safety is a core principle of any surrogacy program. Before a surrogate is matched, clinics conduct a series of infectious disease and blood tests to confirm her suitability and protect the health of the baby and, if applicable, any household members.
Key Blood and Infection Tests
- HIV, Hepatitis B & C, Syphilis, HTLV‑1
Standard screenings that help prevent transmission risks, which is typically done through blood draws and mandatory by ASRM guidelines. - Chlamydia & Gonorrhea Screening
Cervical swabs or urine tests are used to detect common STIs that could affect pregnancy outcomes. - Blood Type and Rh Factor
Essential for anticipating blood incompatibility issues with the intended parents or baby.
Additional Lab Assessments
- Hormone Levels such as TSH (thyroid) and prolactin help confirm overall reproductive health.
- Complete Blood Count (CBC) & Metabolic Panel
Screens for anemia, kidney or liver concerns, and general well-being. - Urine Drug Screen
Ensures the surrogate is free from nicotine, illicit substances, or alcohol, supporting a safe pregnancy.
Reproductive System Evaluations
Before proceeding with a surrogate match, clinics thoroughly assess reproductive health to ensure a successful pregnancy.
Pelvic & Uterine Health
- Transvaginal ultrasound evaluates the uterus and ovaries for fibroids, cysts, or other abnormalities, which is critical for avoiding implantation issues.
- Sonohysterogram or hysteroscopy may be recommended to check for polyps or scar tissue, ensuring a clear uterine environment.
Cervical & STI Checks
- A Pap smear and cervical swab help detect infections and ensure reproductive safety.
- STI screenings, including chlamydia and gonorrhea, are conducted via urine or swabs to safeguard against hidden risks to mother and baby.
Genetic & Advanced Testing
- Carrier screening for genetic conditions (e.g., cystic fibrosis, spinal muscular atrophy) may be recommended, especially with relevant family history.
- Additional diagnostics like HSG or hysteroscopy may uncover less common issues affecting fertility; clinics decide on a case-by-case basis.

Psychological & Emotional Readiness
The mental well-being of both the surrogate and her partner is an essential part of the screening process. This step ensures they’re emotionally prepared to handle the complexities and potential pressures of surrogacy.
Mental Health Evaluation
Clinics follow ASRM guidance on gestational carriers, which recommend a psychosocial consultation and psychological testing when appropriate. These evaluations typically include:
- A clinical interview focusing on motivations, life stressors, and expectations
- Standard mental health questionnaires to screen for anxiety, depression, or other relevant issues
- Counselor-led discussion ensuring the surrogate understands the emotional aspects and has coping strategies
Partner & Family Assessment
The surrogate’s partner or household members may also be evaluated to confirm they:
- Have a stable and supportive home environment
- Understand the emotional journey and are able to support the surrogate
- Undergo STD testing and drug screening, ensuring a healthy household for the pregnancy
Partner Medical Screening
While much of the focus is on the surrogate, clinics also screen her partner (often known as the Primary Support Person) to ensure a healthy and secure environment for the pregnancy.
Screenings Typically Include:
- STD Testing
A partner will undergo blood tests for common sexually transmitted infections, such as HIV, syphilis, and hepatitis, to prevent transmission to the surrogate and fetus. - Drug Screen
A urine test checks for illicit substances and nicotine. If a positive result emerges, medical protocols require treatment or may delay clearance for both parties.
Why This Matters:
- Creates a safer environment for everyone involved
- Ensures the surrogate’s partner supports her through a healthy and committed pregnancy
- Avoids unexpected legal or health issues after the match
- Reinforces transparency and trust between all parties
Psychological & Emotional Readiness
Emotional preparedness is just as important as physical health when matching a surrogate. Clinics aim to ensure that both the surrogate and her family feel confident, stable, and fully informed throughout the journey.
Mental Health Evaluation for Surrogates
ASRM guidelines recommend a full psychosocial consultation for every surrogate candidate, with added testing if needed. Typically, this includes:
- A clinical interview covering motivations, stress levels, and expectations
- Completion of a validated personality questionnaire (e.g., MMPI) to evaluate emotional resilience
- Discussion of issues like pregnancy termination, selective reduction, attachment, and coping strategies during and after pregnancy
Building a Strong Start Through Screening
Thorough medical and emotional screenings help build a safer, healthier, and more successful surrogacy journey, for everyone involved. Clinics follow rigorous protocols, including ASRM-endorsed evaluations, infectious disease testing, and psychological assessments, to ensure gestational carriers are physically and mentally prepared before any match is made.
By understanding these screening steps, intended parents gain peace of mind knowing:
- The surrogate has a clean bill of health and supportive home environment
- Partners are medically evaluated to reduce risk
- Emotional readiness is confirmed to support a smooth process
