<\/span>Introduction<\/strong><\/span><\/h2>\n\n\n\n
Seeing a positive pregnancy test can be an emotional and exciting moment, but it also brings up an important question: what should you do next?\u00a0<\/p>\n\n\n\n
After a home test confirms pregnancy, your doctor will guide you through the next steps, including confirming the pregnancy with a scan and starting your prenatal care. One of the first things you may be advised is to get a few blood tests during pregnancy first trimester, such as an advanced antenatal profile test<\/a><\/strong>. While this might feel like a lot, these tests are a normal and important part of early pregnancy care ^{1<\/sup><\/a>.\u00a0<\/p>\n\n\n\n}
Pregnancy is divided into three stages called trimesters, each lasting about 3 months. The first trimester begins at conception and continues up to around 13 weeks and 6 days ^{2<\/sup><\/a>. This is a very important phase because your baby\u2019s early development begins during this time, and your body also starts adjusting to support the pregnancy.\u00a0<\/p>\n\n\n\n}
Blood tests are an important part of prenatal, or antepartum, care, which means the healthcare you receive during pregnancy. These tests help confirm pregnancy and check for conditions like anaemia, infections, and other health concerns that could affect you or your baby if not detected early. Based on your health needs, your doctor may also suggest additional tests for conditions like thyroid issues or diabetes. These blood tests help identify any problems early so they can be managed in time, supporting a healthy pregnancy ^{1<\/sup><\/a>.\u00a0<\/p>\n\n\n\n}
In this blog, we will explain the first trimester tests, when they are done, what the results mean, and whether they are safe.\u00a0<\/p>\n\n\n\n
<\/span>Why Blood Tests Are Important in the First Trimester?<\/strong><\/span><\/h2>\n\n\n\nBlood tests in the first trimester are important because they help doctors understand the health of both the mother and the baby early in pregnancy. Doctors advise starting pregnancy care early, usually between 6 to 10 weeks, because this helps identify high risk pregnancies and detect existing health conditions. Early testing also allows doctors to screen for problems at the beginning, so that they can take the right steps at the right time ^{3<\/sup><\/a>.\u00a0<\/p>\n\n\n\n}
Below are the main reasons why these blood tests are done:<\/strong>\u00a0<\/strong><\/p>\n\n\n\n
1. To confirm pregnancy and understand early progress<\/strong><\/h3>\n\n\n\nBlood tests measure a hormone called beta human chorionic gonadotropin (beta hCG), which helps confirm a pregnancy, when an individual has signs like missed periods or irregular cycles. However, high levels of this hormone do not always mean the pregnancy is normal, because similar levels can also be seen in conditions like ectopic pregnancy (pregnancy outside the uterus), miscarriage, or other abnormal conditions. Doctors may repeat this test after 48 hours, and if beta hCG levels increase as expected, it usually suggests that the pregnancy is progressing normally in the early stage.\u00a0However, a scan is needed to confirm that the pregnancy is located inside the uterus, which can usually be seen around 5 to 6 weeks ^{1<\/sup><\/a>.\u00a0<\/p>\n\n\n\n}
2. To detect existing health conditions early<\/strong><\/h3>\n\n\n\nBlood tests help identify conditions like diabetes, high blood pressure, and obesity, which can affect how the pregnancy develops if not managed well ^{3<\/sup><\/a>.\u00a0<\/p>\n\n\n\n}
3. To check for anaemia and its cause<\/strong><\/h3>\n\n\n\nA haemoglobin test is done to check for anaemia, which usually indicates low red blood cell count. This can happen due to iron deficiency, long-term illness, or lack of vitamins like B12 or folate ^{4<\/sup><\/a>^,<\/sup>}^{5<\/sup><\/a>. If anaemia is not treated, it can increase the risk of early delivery, poor growth of the baby inside the womb (IUGR), and other complications around birth}^{3<\/sup><\/a>.\u00a0Doctors may do more tests, like checking iron stores (ferritin), vitamin B12, folate, or special blood tests, to find the exact cause of anaemia}^{4<\/sup><\/a>.\u00a0Early treatment, such as iron supplementation, can help reduce these risks}^{3<\/sup><\/a>.\u00a0<\/p>}
