Welcome to the Oops Parents weekly blog. This week we are going deeper into one of the most confusing and emotionally loaded parts of pregnancy: prenatal testing. What tests exist, when they happen, what they actually mean, and what your insurance covers. We are drawing on what Ezgi shared with us in this week's episode, Emily Oster's Expecting Better, plus verified official sources, so you have the full picture. Enjoy!
Recap from "S1 E3 - Parenting between cultures: Miscarriage, NIPT, giving birth in Turkey & Germany"
Ezgi is a renewable energy expert, born in Turkey, who spent nearly a decade living and working across Africa before calling Berlin home. Mum of two: when we recorded this episode she was eight months pregnant, and by the time you're reading this, her second baby has already arrived. Her pregnancy journey spans three countries, a miscarriage, a false-positive NIPT result that turned her world upside down, and two very different pregnancy experiences combining Turkey, Germany and Africa. She has been through the system in ways most of us haven't, and she came to share all of it.
What stayed with us from the episode
A false positive NIPT result nearly broke her and it didn't have to. Ezgi received a positive NIPT result for Trisomy 13 during her first pregnancy. It was presented as near-certain. What she later discovered was that her risk was 23%, meaning there was a 77% chance the baby was completely healthy. And it was a false positive. She gave birth to a healthy boy. Weeks of impossible decisions for nothing.
The right doctor changes everything. The specialist who finally gave Ezgi the information she needed told her in minutes what no one had said before: Trisomy 13 is almost always visible on ultrasound. You don't need to wait for a test result to know. She changed her doctor. She says do the same if something doesn't feel right.
Find your midwife the day you get a positive test. Ezgi didn't know this with her second pregnancy and was already too late to arrange a Beleghebamme. In Germany, a midwife who attends your birth is a separate arrangement from your prenatal midwife and availability is extremely limited. Move immediately.
Read Emily Oster. Expecting Better helped Ezgi understand what her NIPT result actually meant and reduced weeks of unnecessary fear. She calls it the most useful thing she read during her pregnancy.

Your Practical Guide to Prenatal Testing in Germany
Germany has a thorough prenatal care system. But it doesn't explain itself. Here is what actually happens, when, what it costs, and what your insurance covers, with data from Emily Oster's Expecting Better folded in, adjusted for the German context.
A Note Before You Read
The legal entitlements described in this guide are set nationally by the Mutterschaftsrichtlinien and apply the same way across all 16 German federal states. What varies is everything else. Coverage for additional tests depends on your specific situation, your insurer (GKV or PKV), and your individual tariff. The rule for anything not in the standard GKV package: always confirm with your insurer before booking.
First: The Mutterpass and Routine Checkups
At your first appointment, usually around week 6 to 8, you receive your Mutterpass, your complete pregnancy medical record. Bring it to every appointment and to the hospital when you give birth. Statutory health insurance covers checkups every four weeks until week 32, then every two weeks until the due date.
First Trimester (Weeks 1–13)
Standard blood tests covered by statutory insurance
Blood group, Rh factor, rubella immunity, antibody screening, syphilis, and HIV. Urine is also tested for chlamydia. Antibody screening is repeated between weeks 24 and 27.
First ultrasound (around week 9–12) covered by statutory insurance
The first of three standard scans. Confirms the pregnancy, checks development, and estimates your due date.
First Trimester Screening (Ersttrimesterscreening)
Between weeks 11 and 14, a detailed ultrasound measuring nuchal translucency (the fluid at the back of the baby's neck) is combined with two blood markers, PAPP-A and hCG, and your age to estimate the statistical probability of Trisomy 21, 18, and 13. Not part of routine statutory care. Typically €150 to €250 privately. Private insurance usually covers it. Statutory insurance may cover it in high-risk pregnancies, so ask your insurer directly.
What Oster says about this: The combination of nuchal translucency ultrasound and blood test detects about 90 percent of Down syndrome cases, with a false positive rate of around 5 percent, meaning roughly 5 in every 100 women will be told they are "high risk" when their baby is completely healthy. This is a screening, not a diagnosis. It gives you a probability, not a definitive answer. (Oster references the FASTER trial, Malone et al., New England Journal of Medicine, 2005, and Kagan et al., Ultrasound in Obstetrics & Gynecology, 2008)
Non-Invasive Prenatal Test (NIPT)
A blood test analysing cell-free fetal DNA fragments circulating in the mother's blood. Done from around week 10 onwards. Covered by statutory insurance since July 2022, but only if you and your doctor jointly agree it is necessary in your personal situation. Not a routine test for all pregnancies. It screens for three chromosomal conditions:
Trisomy 21 - Down syndrome: The most common of the three. Caused by an extra copy of chromosome 21. Children with Down syndrome can and do live full lives, though they typically have some degree of intellectual disability and distinctive physical features. Survival is possible and in many cases likely.
Trisomy 18 - Edwards syndrome: Caused by an extra copy of chromosome 18. Associated with serious organ malformations. Most babies born with Edwards syndrome do not survive their first year, though in a few cases survival is possible.
Trisomy 13 - Patau syndrome: The most severe of the three. Caused by an extra copy of chromosome 13. Typically involves missing or malformed organs and bones. Most affected babies are either stillborn or survive only briefly after birth.
Types of NIPT commercially available in Germany: Harmony Test, Panorama Test, and Praena Test. All screen for the same three trisomies.
What Oster says about this: The NIPT detects about 99 percent of Down syndrome cases with a false positive rate of around 0.5 percent. Oster draws on a large study by Zhang et al. published in Ultrasound in Obstetrics & Gynecology (2015), covering 146,958 pregnancies, which found 720 confirmed Down syndrome cases but 61 false positives among women told their result was positive. She also references a 2016 meta-analysis by Taylor-Phillips et al. in BMJ Open which echoed these detection rates across a low-risk population. A positive result flags a chromosomal imbalance but does not confirm the condition. This is called a false positive. A negative result, however, is very reliable.
Oster's table shows that a positive or negative NIPT result means something completely different depending on your age, because your baseline risk of carrying a baby with Down syndrome changes dramatically as you get older. For a 25-year-old, a positive result means roughly a 1 in 2 chance the baby has Down syndrome, so still a coin flip, not a certainty. By age 35 the probability with a positive result rises to around 1 in 3, and by age 40 and above a positive result is close to certain. On the flip side, a negative result is reassuring at any age. For a 25-year-old, the remaining risk after a negative result drops to around 1 in 779,830, and even for a 45-year-old it falls to 1 in 3,508. The core message is this: a negative NIPT result is very reliable regardless of age. A positive result however is far from a definitive answer, especially if you are younger, and must always be followed up with confirmatory testing.
This context is almost never explained upfront and it is the single most important piece of information for understanding what your result actually means.
What the NIPT does NOT do:
It does not diagnose, it calculates probability
A positive result means statistical risk is above a threshold, not that your baby has the condition
It cannot tell you whether your baby is healthy in general
It does not replace the detailed anatomy scan, as many conditions are only detectable via ultrasound
If the NIPT comes back positive, further examination is needed to confirm.
Invasive Prenatal Test (IPT)
When screening tests flag a concern or there is a family history of genetic conditions, an invasive prenatal test may be recommended. Unlike screening tests, these give a definitive diagnosis, not a probability. There are two types.
What Oster says about invasive tests overall: Both CVS and amniocentesis involve a needle going into the uterus to collect cells directly from the baby. Both carry a small miscarriage risk. The 1 in 200 figure commonly cited comes from a 1976 NICHD National Registry study, old data conducted before modern ultrasound guidance. More recent studies tell a very different story. A 2006 study by Eddleman et al. in Obstetrics & Gynecology found no statistically significant increase in miscarriage risk from amniocentesis compared to no procedure at all. A 2019 systematic review by Salomon et al. in Ultrasound in Obstetrics & Gynecology puts the procedure-related miscarriage risk at approximately 1 in 800. Oster's conclusion: the real risk is much lower than what most doctors still quote.
Chorionic Villus Sampling — CVS | Weeks 10–13 | Covered when medically indicated
A small tissue sample is taken from the placenta under ultrasound guidance, either through the abdomen or the cervix. The placental cells carry the same genetic material as the baby, allowing definitive diagnosis of all three trisomies as well as inherited conditions like cystic fibrosis.
Key facts:
Done from week 10 to 13, earlier than amniocentesis, giving more time to consider options
Results within a few days to two weeks
Miscarriage risk: approximately 1 in 800 based on current evidence (Salomon et al., Ultrasound in Obstetrics & Gynecology, 2019); the older 1 in 100 figure Oster considers outdated
Does NOT test for neural tube defects like spina bifida
Covered by statutory insurance when medically indicated
Amniocentesis | From week 15 | Covered when medically indicated
A fine needle extracts amniotic fluid through the abdominal wall under ultrasound guidance. The fetal cells are tested for chromosomal conditions.
Key facts:
Performed from week 15 onwards
Gives a definitive chromosomal diagnosis
Also tests for neural tube defects, which CVS cannot
Miscarriage risk: approximately 1 in 800 based on current evidence (Eddleman et al., Obstetrics & Gynecology, 2006; Salomon et al., 2019); the 1 in 200 figure comes from 1980s data Oster considers no longer reliable
Covered by statutory insurance when medically indicated
CVS vs. amniocentesis: The main practical difference is timing. CVS can be done in the first trimester, giving more time and more options. Amniocentesis is done from week 15. Oster notes her own experience led her to choose NIPT first, then follow up, though she is clear this decision is deeply personal and depends entirely on what you would do with the information.
Second Trimester (Weeks 14–27)
Second ultrasound (around week 19–22) — covered by statutory insurance
The second of three standard scans. Checks growth and development. At 20 to 22 weeks the baby is large enough that organ structure and function can be assessed and the sex of the child can usually be determined at this stage.
Feindiagnostik (Detailed Anatomy Scan) — usually NOT covered | Cost varies by practice
If something is flagged in a routine ultrasound, or if it's a high-risk pregnancy, your gynecologist will refer you to a prenatal specialist for a Feindiagnostik between weeks 19 and 23. A specialist uses high-resolution ultrasound to examine every organ in detail, the baby's heart, bone structure, and blood flow via Doppler sonography. This is the scan that can directly see or rule out many of the conditions the NIPT only gives a probability for, including Trisomy 13 which is almost always visible on a detailed ultrasound without the need for a blood test.
Most standard gynecologists cannot perform this and will refer you to a Pränataldiagnostiker. Look for DEGUM Level II/III certification. In Berlin, certified specialists include feindiagnostik.de, bergmannstrasse102.de, and kudamm-199.de.
Gestational diabetes test — covered by statutory insurance
Offered between weeks 25 and 28.
Third Trimester (Weeks 28–40)
Third ultrasound (around week 29–32) — covered by statutory insurance
The third and final standard scan. Checks baby's growth, position, and placenta.
CTG (Cardiotocography) — covered by statutory insurance
From week 30, every checkup includes monitoring the baby's heartrate and checking for preterm contractions.
GBS test (Group B Streptococcus) — covered by statutory insurance
A vaginal smear close to the due date to screen for Group B Streptococcus, preventable with antibiotics during labour.
The Decision That Is Entirely Yours
Oster's central argument, and the most important thing to take from her chapter on prenatal testing, is this: there is no universally right answer. Whether to test, which test to take, and what to do with the results depends entirely on what you as a person would do with the information. Some people want to know everything so they can prepare. Others would rather not carry that weight. Both are valid. The role of the doctor is to give you accurate information and support your decision, not to make it for you.
All prenatal testing in Germany is voluntary. You can decline any test, at any point, without giving a reason. If a result raises concern and your doctor doesn't take time to explain what it means in your specific situation, ask for a specialist referral. You are entitled to one.
