1st Trimester

According to stages of fetal development, human pregnancy is divided into three trimesters. Among all trimesters, the First trimester is considered the crucial one. During this phase, the female body undergoes major changes for preparing for pregnancy. Therefore, the first trimester symptoms includes nausea, vomiting, mood swings, breast tenderness and sore nipples, fatigue, and frequent urination. It is the developmental phase of the fetal organs and organ system. Moreover, this phase marks the surge of female hormones surge due to fetal uterine implantation and placental growth. Therefore, lack of adequate care and monitoring can lead to miscarriages and birth defects. Accelerating research on pregnancy, Central BioHub offers invaluable access to the hard-to-find human biospecimens obtained from pregnant women well stored at the partnered serum bank.

The first trimester covers the first 13 weeks of pregnancy. In the 4th or 5th week of pregnancy, the fertilised egg implants in the uterus, and the embryo begins to grow. During this period, the person begins to experience the first symptoms of pregnancy ad can be detected by a simple urine test. From the 8th week of pregnancy, the embryo develops into the foetus.
One of the first symptoms is the absence of menstruation. This causes typical pregnancy symptoms. As the pregnancy progresses, the typical pregnancy symptoms often start to appear with noticeable changes in breasts, circulation problems, nausea and vomiting, frequent urination, fatigue and abdominal distention.
During pregnancy, the hormone levels change drastically. Shortly after the uterine implantation of the fertilised egg, the body begins to produce the hormone human chorionic gonadotropin (hCG). This has a pregnancy-sustaining effect by stimulating the production of progesterone. Furthermore, the HCG level reaches its peak towards the end of the first trimester. In early pregnancy, an increase in oestrogens causes the breasts to enlarge and prepares them for breastfeeding in the coming months.
Pregnancy can be detected in several ways. The quickest and easiest method is to test for beta-HCG presence in the urine or blood, as this hormone is usually only produced during pregnancy. The detection of the embryo in its gestational sac during ultrasound scanning from the 5th week is the confirmation of pregnancy.
These are the serum samples isolated from the consented pregnant donors, ideal for in-vitro biomedical research. The samples are screened for pregnancy hormones like beta-HCG and are stored at <-18 °C at our suppliers biobank. Central BioHub provides patient information such as the donors, the week of pregnancy, medical history, and multiple pregnancy reports.
