A pregnancy health checkup includes several blood tests and a urine test to assess important hormones like LH, progesterone, FSH, beta-HCG, and prolactin. Some doctors may also recommend tests to check free beta-HCG and testosterone levels. Additionally, tests like the Double Marker (Immulite) test are done to screen for chromosomal conditions of the fetus. These tests not only help to confirm the pregnancy, but also ensure that the hormone levels are balanced for a healthy pregnancy.
