Prenatal Care


The family physicians at Marda Loop Medical provide prenatal care until the patient is assigned to an obstetrician (if patient is high risk or needing a cesarean section) or referred to a family physician who offers low risk obstetrics services. Below is a recommended schedule for tests performed during pregnancy. The tests aim to provide basic information while tracking a routine pregnancy. Please consult with your doctor if you have any questions.

A pregnancy is tracked according to gestational weeks, calculated based on the date of a woman’s last menstruation. If there is a discrepancy between the date of a woman’s last menstruation and the gestational age, it will be found during the early (first trimester) ultrasound and an accurate gestational age will be calculated.

The Process

Around the time of the delayed menstruation, a urine or blood test is performed to determine pregnancy. A visit is scheduled every 2-3 weeks until 16 weeks thereafter.

At 4 weeks (first visit for pregnancy): A detailed maternity file is opened, and family personal history is recorded.

At 7-8 weeks: A woman should have (1) an ultrasound to determine the location of the pregnancy sac, size and vitality (heartbeat) of the fetus. Routine tests are done for: blood count, ferritin, urinalysis, blood type (and RH antibodies level if negative), rubella antibodies, syphilis, hepatitis B and C. Some patients may require thyroid activity testing.

Week 11-12: Early chromosomal genetic diagnostic testing and placental structure (chorionic placenta) examination is performed.

Week 12 (10-14): (2) Ultrasound is performed to determine nuchal translucency or fetal development and first trimester screening is done – a lab test is done 3 days before this ultrasound. Patient is referred to a maternity clinic where they will receive a complete maternity physical exam which involves a pap smear (screening for cervical cancer cells), swabs for bacterial vaginosis, chlamydia and gonorrhea.

Weeks 16 – 32: Patient is transferred to maternity clinic and monthly visits start.

Week 17: Triple screen test, feto-protein or amniocentesis and blood count test is conducted if needed.


Week 18–19: Fetal Movements are detected through (3) detailed ultrasound.

Week 28: Gestational glucose tolerance test, blood count and RH antibody levels are measured for those with negative blood type.  A visit to the physician is arranged to discuss glucose test results and talk about receiving RH immune globulin vaccine if RH negative. Review of fetal growth.

Week 32-39: Begin weekly tracking of fetal growth weight.

Week 40: Follow-up with doctor for ultrasound and monitoring biophysical profile every 2-4 days.

Week 41-42: Referral to the delivery room to perform a stress test or induce labour. Up until week 32, the pregnancy will be tracked once a month, then every 2-3 weeks until week 36, and finally every 1-2 weeks until week 40. Beyond this stage, the pregnancy will be passed over to another department which specializes in overdue pregnancies (in certain cases the pregnancy will be passed over to the hospital delivery room).
