Guide To Tests And Scans
During Pregnancy
Congratulations!… You have taken a home pregnancy test. and that is positive!!! Your pregnancy is an exciting time for you and your family. You may be busy planning and dreaming about your baby and how to prepare for its homecoming. During your pregnancy, we will check your and your baby’s health and well-being by carrying out some tests. This information is an attempt to answer common questions that you may have regarding these investigations.
Confirmation Of Pregnancy
Pregnancy can be confirmed by a urine test done at home or in the hospital lab. In some instances, it is necessary to check for the levels of the pregnancy hormone (β-HCG) in the blood.
BEFORE 11 WEEKS: Early pregnancy scan (Viability scan): We perform this scan to determine the stage of your pregnancy, to check the baby's heartbeat and to rule out the possibility of an ectopic pregnancy (pregnancy occurring outside the womb).
BETWEEN 11 to 13 WEEKS: Down’s Syndrome Screening and the Dating Scan: Screening for Down’s syndrome is offered to all pregnant women. It is done by a blood test called the “Double Marker test” which is combined with a scan done at 11 to 13 weeks to measure what we call “Nuchal Translucency” or NT. The combination of the blood test result and the scan helps us to determine the baby’s risk of having common chromosomal problems like Down’s syndrome.
The estimated “date” of delivery or EDD is calculated during the “dating” scan. Certain abnormalities in the baby can be checked at this stage. If you miss the early tests for Down’s syndrome screening, another blood test, the “Quadruple marker test” can be offered between 15 and 21+6 weeks. Further details regarding the screening and diagnostic test for Down’s syndrome are available in a separate leaflet.
Booking Blood Tests:
These are the blood tests which are typically done at the time of your first visit during the pregnancy.
Blood group type and Rh factor: This test will tell us what blood group you belong to – A, B, AB or 0, and whether you have blood group antibodies. The test will also show whether you are Rh positive or Rh negative.
Tests for Thalassemia and Sickle Cell Disease: Thalassemia and sickle cell disease are genetic conditions that are passed on from parents to children. People originating from some specific regions of the world are more likely to be carrying the defective gene causing these diseases. Thalassemia causes severe anaemia in sufferers. Sickle cell causes anaemia bouts of severe pain and occasionally complicated infections. Knowing about the carrier status will be important for both the mother’s and baby’s health.
Complete blood count: This test includes the measurement of various blood components such as red blood cells, haemoglobin white blood cells and platelets. Further tests and corrective treatment will be offered if alterations in the levels of the blood components are found.
Screening Test For Maternal Infections:
A screening for HIV, Hepatitis B, Hepatitis C, Syphilis (VDRL test) and Rubella is carried out at the booking visit. Treatment of syphilis, if found during pregnancy, reduces the risk of infection in the baby. In cases where women may have infections like Hepatitis B, C and HIV, certain steps can be taken to reduce the chances of transmission to the baby. Rubella (German measles) infection during pregnancy can cause serious problems for the baby. TImmunity tests are done so that appropriate immunization for future pregnancies can be offered after delivery.
Other Tests:
On the first booking visit, a random blood sugar (RBS) test is done. It can be done at any time of the day and no fasting state is required. The thyroid gland function is checked by testing the levels of a hormone called TSH (thyroid stimulating hormone).
Apart from these, at each visit, you will be asked to provide a urine sample to look for sugar, and protein and to rule out urinary infections.
Between 18-20 Weeks:
Anomaly scan: This scan is performed to make sure that the baby is normal. This is a detailed scan and may take around 45 minutes so please plan your day accordingly. Occasionally, the baby lies in a position that does not allow for checking of all the organs. If this happens, you will be asked to come back within a week to complete the scan. Please note that sex determination is illegal in India and will not be offered.
Between 24-28 Weeks:
Blood tests: Repeat complete blood count is done. At 24-28 weeks, a Glucose Tolerance Test (GTT) is done to screen for diabetes in pregnancy. Your first blood sample will be obtained when you are fasting. Following this, you would be given a glucose drink and then 3 separate blood samples would be obtained at 1 hour, 2 hours and 3 hours respectively.
Growth Scan:
This scan is usually done at 32 weeks. It may also be offered at 28 and 36 weeks depending on individual circumstances.
