Pregnancy brings excitement, but it also brings many questions about blood tests, scans, baby growth, genetic screening, and safety.
Many mothers feel anxious when they hear terms like beta-hCG, NT scan, dual marker, NIPT, Hb electrophoresis, or anomaly scan.
In my clinical experience, prenatal tests are not meant to create fear — they help us detect concerns early and plan safer care.
This guide explains which tests are needed, when they are done, and how they help protect mother and baby.
Prenatal screening and tests help assess the mother’s health, baby’s growth, genetic risk, infection risk, placenta, liquor, and pregnancy safety.
Prenatal screening means tests done during pregnancy to check whether the pregnancy is progressing safely.
These tests may include:
At Vardaan Hospital, Goregaon West, prenatal tests are planned according to:
The purpose is simple:
Detect early. Decide early. Treat early. Protect mother and baby.
NHS explains that screening tests in pregnancy are offered to help find conditions that could affect the mother or baby, and the choice to accept screening remains with the patient.
Dr. Dimple Doshi’s Tip:
Prenatal testing should always be explained clearly. A mother should know why a test is advised, what it can detect, and what the next step may be.
Prenatal screening is also called antenatal screening, pregnancy screening, fetal screening, and pregnancy testing.
Common terms include:
Prenatal tests are important because many pregnancy problems can be silent early but manageable when detected at the right time.
Many mothers feel completely normal even when there is:
Prenatal screening helps your doctor:

Screening tests estimate risk, while diagnostic tests confirm whether a condition is present or absent.
Type of Test | What It Means | Examples |
Screening test | Tells whether risk is low or high | NT scan, dual marker, quadruple marker, NIPT, Hb electrophoresis carrier screening |
Diagnostic test | Confirms the diagnosis | CVS, amniocentesis, fetal genetic testing |
A screening test may say:
But screening does not always mean the baby is affected.
A diagnostic test checks fetal or placental cells and can confirm selected chromosomal or genetic conditions.
ACOG explains that prenatal screening tests assess the chance of certain genetic disorders, while diagnostic tests such as CVS and amniocentesis examine fetal or placental cells for more definite answers.
Dr. Dimple Doshi’s Tip:
A “high-risk” screening report does not always mean the baby has a problem. It means we need further counselling and sometimes confirmatory testing.
Early pregnancy tests confirm pregnancy location, dating, heartbeat, mother’s baseline health, blood group, infections, sugar, and thyroid status.
In early pregnancy, your doctor may advise:
An early scan may check:
Usually include:
Dr. Dimple Doshi’s Tip:
Early pregnancy testing is not only about confirming pregnancy. It also helps us detect silent issues like anemia, thyroid imbalance, urine infection, and blood group-related risks.
Repeat beta-hCG is used in selected early pregnancies to assess pregnancy progression when scan findings are too early or symptoms raise concern.
Repeat beta-hCG is not needed for every pregnancy.
It is useful when there is uncertainty in very early pregnancy.
In many early viable pregnancies, beta-hCG rises over 48 hours.
But interpretation depends on:
Repeat beta-hCG is a monitoring test, not a guarantee. It should always be interpreted with symptoms and ultrasound findings.
Once a clear intrauterine pregnancy with fetal heartbeat is seen on ultrasound, repeated beta-hCG usually has limited value.
At that stage, ultrasound follow-up is more useful.
Dr. Dimple Doshi’s Tip:
Please do not compare beta-hCG numbers with another pregnancy. The trend, symptoms, and ultrasound findings matter more than one isolated value.
Hb electrophoresis helps identify thalassemia, sickle-cell trait, and other hemoglobin disorders that may affect the baby if both parents are carriers.
Hb electrophoresis is also called:
It helps detect whether the mother is a carrier of:
ACOG states that hemoglobinopathy testing may be done using hemoglobin electrophoresis or molecular genetic testing.
NHS recommends sickle cell and thalassemia screening early in pregnancy, ideally before 10 weeks, because early testing allows time for partner testing and informed decisions if the baby is at risk.
If the mother is a thalassemia or sickle-cell carrier, the father should also be tested to understand the baby’s risk.
This is a crucial counselling point.
The baby’s risk of major hemoglobin disorder is usually low.
The father should be tested.
The baby may be at risk of a serious hemoglobin disorder, such as:
In such cases, the couple may be advised:
ACOG’s carrier screening FAQ explains that hemoglobin electrophoresis is one method used to test for hemoglobinopathies.
Hb electrophoresis does not mean something is wrong with the baby. It simply checks whether parents carry genes that could affect the baby if both partners are carriers.
Dr. Dimple Doshi’s Tip:
If the mother is a carrier, partner testing is very important. This helps the couple understand the baby’s actual risk instead of worrying unnecessarily.
First trimester screening helps assess early baby development, chromosomal risk, pregnancy dating, and maternal baseline health.
First trimester testing may include:
NT scan measures the fluid space behind the baby’s neck.
It is commonly done in the first trimester as part of chromosomal risk assessment.
Dual marker is a blood test used with the NT scan to estimate the risk of selected chromosomal conditions.
This may include:
It gives a risk estimate, not a final diagnosis.
Dr. Dimple Doshi’s Tip:
First trimester screening is most useful when done at the correct pregnancy week. Please bring all previous reports so the test timing can be planned properly.
NIPT is a blood test that screens fetal chromosomal risk using cell-free fetal DNA present in the mother’s blood.
NIPT is also called:
It may screen for selected chromosomal conditions such as:
NIPT may be discussed when:
NIPT is a screening test.
It is highly useful in selected situations, but it is not the same as a diagnostic test.
If NIPT is high risk, confirmatory testing like CVS or amniocentesis may be advised after counselling.
Second trimester tests assess baby anatomy, maternal health, diabetes risk, infection risk, and pregnancy progress.
Second trimester testing may include:
Quadruple marker may be advised if first trimester screening was missed or if the doctor feels it is needed.
It is a screening test.
It does not confirm a chromosomal condition by itself.
Gestational diabetes screening is usually planned around mid-pregnancy as per clinical protocol.

An anomaly scan checks the baby’s major organs, spine, brain, heart, limbs, placenta, liquor, and overall fetal structure.
Anomaly scan is also called:
It usually checks:
Anomaly scan helps detect major structural concerns early enough for counselling, planning, fetal medicine referral, and delivery preparation if needed.
No test can guarantee everything.
But a well-timed anomaly scan provides important information about fetal structure and pregnancy planning.
Dr. Dimple Doshi’s Tip:
Please do not miss the anomaly scan window. This scan gives very important information about the baby’s organs and helps us plan further pregnancy care.
CVS and amniocentesis are diagnostic tests used when a clearer answer is needed after screening, family history, or scan findings.
Diagnostic tests may be advised when:
CVS means chorionic villus sampling.
It tests placental tissue.
Amniocentesis tests amniotic fluid around the baby.
These tests are not routine for every pregnancy.
They are advised only when clinically needed after detailed counselling.
Dr. Dimple Doshi’s Tip:
When diagnostic testing is advised, the couple should receive calm, step-by-step counselling. The aim is clarity, not pressure.
Routine pregnancy tests check anemia, blood group, infections, sugar, thyroid, urine infection, and other mother-related health risks.
Common routine tests may include:
These tests help identify common but important pregnancy issues such as:
High-risk pregnancy may need extra blood tests, ultrasound scans, Doppler, NST, growth monitoring, and specialist review.
Extra testing may be needed if the mother has:
High-risk pregnancy monitoring may include:
For detailed care, add internal link to high-risk pregnancy care in Goregaon West.
Prenatal test timing depends on pregnancy week, symptoms, risk factors, previous history, and scan findings.
A general pregnancy test timeline may include:
Pregnancy Stage | Common Tests |
Early pregnancy | Urine pregnancy test, serum beta-hCG, repeat beta-hCG in selected cases, early ultrasound |
First visit | CBC, blood group, Rh type, sugar, TSH, urine test, infection screening, Hb electrophoresis |
First trimester | Dating scan, NT scan, dual marker, NIPT in selected cases |
Second trimester | Anomaly scan / Level 2 scan, quadruple marker if needed, routine blood tests |
Mid-pregnancy | Gestational diabetes screening, hemoglobin review, urine test |
Third trimester | Growth scan, Doppler if needed, NST if indicated, delivery planning |
High-risk pregnancy | Extra growth scans, Doppler, NST, blood pressure, sugar, urine protein, fetal medicine review |
This timeline may change depending on:
Dr. Dimple Doshi’s Tip:

Important prenatal tests include early ultrasound, blood group, CBC, infection screening, sugar, thyroid, Hb electrophoresis, NT scan, dual marker, NIPT, anomaly scan, growth scan, and Doppler when needed.
The exact list depends on:
A good pregnancy test plan should be personalized, not copied from another patient’s prescription.
Ans. Prenatal screening tests are strongly recommended because they help detect maternal and fetal concerns early.
However, screening should be explained clearly, and the mother should understand why each test is advised.
Ans. No. Repeat beta-hCG is not needed in every pregnancy.
It is mainly used when pregnancy is very early, ultrasound is inconclusive, bleeding or pain is present, or ectopic pregnancy needs to be ruled out.
Ans. Hb electrophoresis is a blood test used to screen for thalassemia, sickle-cell trait, and other hemoglobin disorders.
It helps identify whether the mother is a carrier and whether partner testing is needed.
Ans. If the mother is a thalassemia carrier, the father should also be tested.
If both parents are carriers, genetic counselling and further fetal testing may be discussed.
Ans. NT scan is usually done in the first trimester to assess early chromosomal risk.
Anomaly scan is done later to examine the baby’s major organs and body structures.
Ans. NIPT is a more advanced screening test for selected chromosomal risks, but it is still a screening test.
The choice between dual marker and NIPT depends on age, risk factors, scan findings, previous history, and counselling.
Ans. No. A high-risk screening result does not confirm that the baby has a problem.
It means further counselling and possibly diagnostic testing may be needed.
Ans. Diagnostic tests like CVS or amniocentesis can confirm selected genetic or chromosomal conditions.
These are advised only when needed after screening, scan findings, or family history.
Prenatal screening and tests are an important part of safe pregnancy care.
They help assess the mother’s health, baby’s growth, genetic risk, infection risk, placenta, liquor, and overall pregnancy safety.
