While you go through many bodily changes in the first trimester, most of them are not visible. The tests may give you clues regarding any health concern you or your baby might have, or they may even diagnose a problem. The tests done during the first trimester are a combination of foetal ultrasound and maternal blood tests. Different tests that are done during the first trimester of pregnancy, from week 1 to week 13, are:</p><ul><li><strong>Urine pregnancy test:</strong> The first test that is performed to confirm that you are expecting is the urine pregnancy test. You can do it yourself with the help of home kits available for this test. After the confirmation of pregnancy, your doctor calculates your due date based on last menses or with the help of an ultrasound.</li><li><strong>Physical examination:</strong> This includes breast and pelvic examination, measurement of blood pressure, and monitoring your weight.</li><li><strong>Complete blood count:</strong> To check the count of blood cells and anaemia.</li><li><strong>Blood group and Rh factor:</strong> The doctor estimates your blood type and if you are Rh-positive or Negative. If you are Rh-negative and your partner is Rh-positive, your blood may develop antibodies against the foetal blood.</li><li>Ultrasound: At around 11-14 weeks, you may go through the ultrasound test. This is done to check your baby’s health and development.</li><li><strong>Human chorionic Gonadotrophin or hCG test:</strong> This blood test estimates the hormone hcg, a pregnancy indicator. Abnormal levels of this hormone indicate a chromosomal abnormality.</li><li><strong>Pregnancy-associated plasma protein A:</strong> This protein comes from the placenta throughout initial pregnancy. Abnormal levels of this protein in your blood may indicate a genetic defect.</li><li><strong>Ultrasound for foetal Nuchal translucency (NT):</strong> An ultrasound is used to check the neck of the foetus for thickening or enhanced fluid, which might suggest a problem.</li><li><strong>Tests for specific diseases:</strong> your doctor may evaluate your blood for diseases such as STDs, Hepatitis B, HIV, Rubella, measles, and cystic fibrosis.</li><li><strong>Cell-Free DNA Test or Non-Invasive Prenatal Screening (NIPS):</strong> This is a screening test to check your baby’s DNA in your blood. This test is executed after ten weeks of pregnancy. This gives an estimation of the possibility of genetic defects in the baby like Down’s syndrome.</li><li><strong>Chorionic Villus Sampling (CVS):</strong> This is a diagnostic test, which is performed around 10-13 weeks of gestation. The cells of the placenta are examined to confirm if the baby has a chromosomal defect.</li></ul><h2 id="Risk">Is There Any Risk Associated With The Screening Tests?</h2><p>Usually, these screening tests are not risky.
